DESIGNING *for humans

Canine Ergonomics

 

Canine Ergonomics: The Science of Working Dogs, is due out later this month from CRC press and was written by William Helton (who was, coincidentally, a classmate of mine in grad school).  The book is an attempt at bringing disparate perspectives together into a definition of canine ergonomics, with topics including the role of dogs in mine detection, search and rescue and assisting people with disabilities.

Product Ergonomics in Metropolis

The March issue of Metropolis is focused on products, with the theme of Good Design.  And it contains several articles with a specific focus on ergonomics.  Niels Diffrient (illustrated above) presents what might be read as a self-contradicting design process, in The Real Driver.  On the one hand he posits a master-of-the-universe expertise as a best practice over contextual research:

"if you know what people do, how they do things, what their reactions are—and if you can measure all this—then you have a foundation reference for what they could use or want. You don’t have to go out and ask them, or track previous sales records, or determine what products are selling well."

On the other hand, the result of this approach is a chair that was "ten years in the making—I realized that people needed more comfort with less complication. By that, I mean fewer but­tons, levers—everything."  I recognize that I'm oversimplifying, but one wonders if the need for a less complex chair could have been identified with a few weeks of research rather than ten years of tinkering (although maybe getting it simple was all in the tinkering).

In the same issue Don Norman's Selective Memories, gives perspective on the evolution of design focus:

"If the last century was about rationality and reason (or attempted to be), let’s hope this one ushers in a deeper appreciation of human behavior. Ideally, logic and reason would remain important, but cognition (how we understand things) and emotion (how we value them) should play equally important roles."

Perhaps the fact that Niels and Norman - both well into their golden years - were the representation for ergonomics issues, speaks to the continued perception of human factors as the domain for gurus, while design is the realm of young rock stars?  But the content is is balanced by A Call to Arms, examining high-tech prosthetics for returning soldiers - "the ultimate ergonomic challenge."

Last, but not least, check out Ben Katchor's The Nozzle, a pseudo-nostalgic comic strip perspective on the role of customer research in design and marketing.

Human Factors of Imaginary Objects

Bruce Stirling's new undertaking, The Imaginary Gadgets Project, has re-inspired my thinking around the human factors of imaginary objects.  Stirling describes his project as "a catalog of the weirdest things imaginable."  Compared to real-life gadgets, imaginary ones include everything from "futuristic gadgets" (pictured above), to "radically impossible gadgets" and "gadgets of the fantastic and the occult (crystal balls, magic wands); the personal hardware of the saints and the gods", to name a few categories.

What interests me about such devices is not their obviously incredible and/or supernatural capabilities, but rather the more mundane aspects of how a user would interact with them.  For no matter how complex, esoteric or unfathomable the capabilities of an imaginary object, there must be some connection between the user and the system, be it tangible, telepathic or otherwise. 

I said I was re-inspired to look at this area because in 2007 I had looked at the human factors of nonobjects, nonobjects being branko Lucic's forthcoming design fiction book.  For example, I examined the ergonomics of dialing the Tarati, a touch-less phone, pictured below, that has spaces instead of buttons (ergonomic issues included lack of tactile feedback and need to accommodate a range of finger diameters).

Curiously, the nonobjects book has yet to be published, making it something of an imaginary object itself.

So what's the value of this imaginary human factors & usability beyond intellectual curiosity?  I think there are at least two relevant benefits.  The first is inspiration - thinking about how people might interact with a crystal ball or time machine takes us outside of our everyday human-computer interaction thinking, and can give us ideas, if only metaphorical, about how to design a user experience.  I don't have any proof, but there's a good chance that the Wii controller was influenced by light sabers.

The second benefit is more subtle, but perhaps more important - motivation.  Consider that virtually every product a designer works on prior to its development and launch is an imaginary product.  It's really just a question of degree.  A new online form is not much different than an existing one that it might be replacing, but whatever small details need significant enough changes to require a designers input are imaginary until they are designed and realized.  Similarly, determining the appropriate human factors for the controls on a new car is necessary because the controls for that car do not yet exist.  In other words, the very nature of human factors design is making the imaginary concrete.  Studying the hypothetical human factors for imaginary products is really just an extreme version of what we do as designers every day. 

I plan to follow Bruce Stirling's thread and find out what practical ideas might come from these fantastic gadgets.  Now there is the other side of the coin...an imaginary human factors - but that's for another discussion.

IDSA Updates

The Industrial Designers Society of America has launched their new web site at IDSA.org.  In addition to an improved visual layout, the site takes a direct approach to user-centered design by providing navigation options for three targeted groups: public, members and media.  Once you select your group, the relevant sub-set of primary navigation options appear.  This is one of those information architecture approaches that is often discussed but rarely applied, so I'm curious to see if it works out effectively.

{note the site design was up as of 4 Feb, but then went back to the old version and a note that the updated design would be back soon}

In other IDSA news, Human Factors section chair Steve Wilcox was voted as IDSA President-elect.  Therefore I am taking over as section chair until the fall elections, so please contact me (robtannen at hotmail dot com) with any questions or suggestions. The full list of IDSA interest sections and chairs is listed here.

Asterisks *2 Feb 2009

Asterisks - our new label for brief notes of interest.  In this case, items that relate to the visual, auditory and tactile senses.

• Visual - Rafe Needleman of CNET writes about "The Myth of Width: When widescreens don't work".  He takes on the ongoing trend of widescreen format displays in a range of consumer products, a presentation form that isn't always task approrpriate:

One area where I believe we should (but probably won't) see continued releases of consumer portrait-mode displays, though: personal navigation devices. Recently the PND companies have started to offer wide-screen navigation units. How does this make sense? When we use a computer-generated map that's always rotating to show us where we're going at the top of the screen, why do we care what's out the side windows? It's what's coming up that matters. Serious navigation products for back-country hikers are portrait mode. The wider you make a map display the more you sacrifice useful information for distraction--although, again, it makes the devices look cool.

 

• Auditory & Tactile - File this one under why didn't I think of that?  Carnegie Mellon University researchers are using simple microphones and software to turn virtually an surface into a gestural-based controller.  From a tabletop to your leg.  See the video for a clear technical explanation (from the interaction-focused site johnnyholland.org)

Automobile Dashboard Design

While the prestige of this year's North American International Auto Show was somewhat diminished by the poor financial condition of the auto industry, there was a strong showing for the state-of-the-art in dashboard user interfaces.

Automobile manufacturers are frequently leaders at bring new technology to mainstream consumers (e.g. satellite radio, GPS), so it seems like it's time the industry caught up to the rapidly changing field of interface design.

The New York Times reported on "Dashboards that Promise to Do More Than Inform":

Drivers accustomed to receiving vehicle information from familiar needle-and-dial gauges will soon benefit from the work automakers are doing to create information systems that are more flexible and take advantage of the latest developments in computer displays.

Instrument panels that can be customized to a driver’s whim are already available, but the next wave could include designs where the gauges are not fixed in place on the dashboard

I'm all for adapting interfaces to drivers' needs, but hope that the customization is limited to effective information displays that support visibility and reaction time.

Of particular note was a system demonstrated by Mercedes, which uses an array of driving behavior sensors to "sense" if the driver may be inattentive or drowsy, and displays a coffee cup warning light (pictured above). 

The magazine design mind by Frog has also recently published an article, "Driver Experience Design", that reviews other emerging technologies in automobile control design, including haptic feedback for safety:

Nissan is also working on a design called “Eco-Pedal” that uses chip sensors to determine when excessive throttle is causing poor fuel mileage, triggering a push-back mechanism on the driver’s foot. Volvo’s “City Safety” system uses radar technology to sense imminent collisions at speeds between nine and 18 mph, and it automatically applies the brakes when closing speeds are too high.

Ergonomic Innovations at CES

I'm trying to track the hundreds of new product announcements at this year's Consumer Electronics Show.  And while there's always innovations in technical functionality, it's hard to spot a direct ergonomic improvement. 

But here's a couple of exceptions to that rule:

• The Samsung HMX-R10 video camera(pictured above).  A CNET previewer said that it features a "lens that's angled at 25 degrees so you can grip the camera more naturally in front of you for both photos and video--or at least that's what I'm hoping for."
• The Kodak Z980 digital SLR camera  has two shutter buttons.  One in the traditional top right, and the other on the side of the body for taking pictures in portrait mode ((see video below).  In other words when you hold the camera sideways, you have a more accessible and natural reach to the secondary shutter button.

Ergonomists Without Borders

I think there's a real opportunity for ergonomic expertise to support many of the international programs that support developing communities.  For example, Engineers Without Borders enables the "implementation of sustainable engineering projects, while involving and training internationally responsible engineers and engineering students."  These projects are frequently focused on basic human needs such as water purification/delivery and sanitation.  Many of these solutions require human power.  I wonder whether ergonomic expertise has been applied to the design and implementation of these systems.  This is particularly important, given the diversity of anthropometric characteristics across the served communities.

One organization that is contributing is Synergo Arts, which is a "resource for ergonomics education, consulting, and design for communities of artists and artisans around the  world, to maximize their health, income, performance, productivity, and the quality of the art or craft that they create."  Their ergonomically designed weaving bench (pictured above) also won a User-Centered Design Award from the Human Factors & Ergonomics Society in 2007.  The bench is actually produced by local carpenters (in South America) for local weavers, thereby benefiting two industries.

If you know of similar organizations or individuals working towards improving ergonomics in developing communities, please contact me.

From "The Greatest Product Demo Ever" to the "Macbook Wheel"

...or from the sublime to the ridiculous.  Two interesting videos in juxtaposition:

Scott Berkun of the Harvard Business Review discusses the 40th anniversary of the "The Greatest Product Demo Ever" - computer pioneer Douglas Englebart's presentation that introduced the world to the computer mouse, email, hyperlinking, and other innovative human-computer interaction solutions.  The video, above, is a little hard to hear, so turn up your volume.  Bekrun uses the demo as a jumping point for a discussion on why it takes so long for great products to reach the mainstream:

One might ask "Why are we so stupid that we can't adopt good ideas faster?" But the problem isn't about being smart or stupid. New ideas travel through cultures at much slower rates that we realize, especially if the idea requires 1) throwing something away and replacing it with something else 2) re-learning skills or 3) co-ordination by large independent organizations.

 

Fast forward to the present.  The satirical Onion has created a convincing demo of the "Macbook Wheel", a keyboard-less laptop that uses an iPod navigation wheel and button for all functions - including typing.  It's simplicity that violates usability.  I especially enjoyed the automatically suggested sentence completion choices.  One wonders whether Englebart's demo received similar disbelief and laughter at the time.

Objectified Trailer Online

 

Objectified - The trailer for this forthcoming industrial design-focused film by Helvetica creator Gary Hustwit is available.   The new film is focused on famous industrial designers (think Jonathan Ive, Karim Rashid), but I had emailed Hustwit several months ago about the inclusion of design research and human factors, since it plays an important role in the ID process.  Hustwit responded that IDEO's Jane Fulton Suri was interviewed as part of the film.

"Green" Ergonomics in LEED Building Design

 

Several months ago I discussed the relevance of user-centered design to the successful design of sustainable products and services.  Now a more concrete (literally) example of the intrinsic connection between human factors and green design.  

Alan Hedge writes about The Sprouting of "Green" Ergonomics (PDF) in the December issue of the HF&ES Bulletin.  Hedge reports on the new version of the U.S. Green Building Council's LEED Green Building Rating System, which includes specific guidelines and credits for creating an ergonomic environment.

The guidelines focus primarily on office workstation ergonomics (although industrial settings are touched on as well).  For example, the LEED guidlines cover standards around display adjustability and glare, work surface dimensions, and chair adjustability.  You can download relevant "green" ergonomic checklists from Cornell's ergonomic resource.

Adding ergonomics to LEED requirements seems like a natural extension to me - both are targeted at improving the health and comfort of individuals who work within buildings.  There may also be some direct correlations between the more traditional LEED categories such as materials & resources, and ergonomics. For instance, a poorly fitted workstation may be more readily replaced than one chosen appropriately - thereby leading to increased materials use.

Hedge also makes the point that the new LEED guidelines will change perceptions about office ergonomics - from a reactive, problem-solving model in most cases, to a proactive problem-avoiding approach as it is intended.

 

"There is No Angle on the Human Body that was Designed for a Collision"

Acura is running an elegant new TV ad highlighting vehicle safety.  It shows human bodies in motion as if they were in collisions, but out of the context of an automobile. 

Not to be taken too literally, but I might disagree that "there is no angle on the human body that was designed for a collision" - case in point, the orbit that protects the eye -

"The bony structures of the orbit protrude beyond the surface of the eye. They protect the eye while allowing it to move freely in a wide arc." (Merck Manual)

Brain-Computer Interfaces on 60 Minutes

A very impressive story on 60 Minutes on the real-world application of brain-controlled interfaces that allow disabled individuals (and potentially, everyone) to control software and hardware interfaces. 

"Once in a while, we run across a science story that is hard to believe until you see it. That's how we felt about this story when we first saw human beings operating computers, writing e-mails, and driving wheelchairs with nothing but their thoughts."

See embedded video above and link to story transcript. 

And for more information on the general topic, read my review of the book Neuroergonomics.

"Designers' Version of the Scientific Method"

Lots of blog buzz around "design thinking" re: the New York Times article Designing is More than Packaging - see comments by Steve Portigal and Christoper Fahey to name a few. 

I agree with Fahey's observation that the NYTimes article "included by far the clearest summary of what design thinking is that I’ve ever read, including from all the design thinking leaders".  Then again, it sounds a hell of a lot like just plain old user-centered design to me:

"While definitions vary, design thinking usually involves a period of field research — usually close observation of people — to generate inspiration and a better understanding of what is needed, followed by open, nonjudgmental generation of ideas. After a brief analysis, a number of the more promising ideas are combined and expanded to go into “rapid prototyping,” which can vary from a simple drawing or text description to a three-dimensional mock-up. Feedback on the prototypes helps hone the ideas so that a select few can be used."

What I did find more interesting, was the sentence in the Times article that immediately followed that description:

"It’s the designers’ version of the scientific method,” explains Greg Galle, co-founder and managing partner of the C2 Group, a consulting firm based in Half Moon Bay, Calif. “It’s sloppy and messy and not nearly as disciplined as the scientist, but we do trial and error and we hypothesize and test and we see what we learn and then we go back and try again.”

For those interested in understanding more about true scientific methods, read here.

Fitbit - Tracking Physical Behavior

So here's my take on the "next big thing" in the little world of user research for product design.  Measurement of physical activity is typically tedious (e.g. time and motion studies), highly expensive, or inaccurate (participant self-reporting).  Despite these limitations, it has the potential to be very valuable in quantifying user behavior, such as level of exertion, or rest/motion periodicity in shifts.  For example, the ROI for a new system or product may depend on measuring before and after differences in user physical effort or movement.

I recently learned of the soon-to-be launched Fitbit, what one of my colleagues described as a "pedometer on steriods".  And it is marketed towards the health/fitness marktet.  But what makes its particularly useful to user research are its accuracy, battery life (claimed at 10+ days) and reporting features.  According to the Fitbit web site:

"The Fitbit Tracker contains a motion sensor like the ones found in the Nintendo Wii. The Tracker senses your motion in three dimensions and converts this into useful information about your daily activities. The Tracker measures the intensity and duration of your physical activities, calories burned, steps taken, distance traveled, how long it took you to fall asleep, the number of times you woke up throughout the night and how long you were actually asleep vs just lying in bed. You can wear the Tracker loosely in your pocket or clipped to your clothing, even bras."

Here's a screenshot of the tracking web interface...

 

 

Launch date is "late Dec- early Jan". Well if they're anything like LiveScribe, maybe March or June, but I'd love to be surprised

The Design (Researchers) Accord

I just wrote a posting for the new Bresslergreen blog on how design researchers can modify their practices and methods to support the environment, based on the guidelines provided by The Designers Accord.

Photosynth: 3D Visualization of Digital Photos

Microsoft Live Labs has launched a public version of Photosynth, a Web tool that uses the overlapping information in a set of still photos taken in a space to create a 3D mapping between the images. I put together a quick collage of the product "museum" space in my office - the more pictures you take from different positions, the better. When viewing, use "f" for full screen and "ctrl" to toggle to the data points.

Potential applications to user research include modeling observed work environments when videotaping is not allowed or impractical.  There's also the possibility of using Photosynth to create 3D views of products or concepts, although it's better suited for large spaces than close ups.  But for one example, see this joystick and note how you can move around it from all sides.

Like IBM's Many Eyes for text and data visualization, all Photosynths currently created are publicly viewable.  Understandably the site has a high traffic load so prepare to be patient.

Service Design: A Model for Green Product Design

While there's clearly a great deal of attention around "green design" these days, there's very little guidance on how to design such products (e.g. energy-saving, recyclable, super-efficient, etc.) from a user-centered perspective.  One could argue that there's nothing unique about such products that a typical user-centered design approach would not already accommodate.

But an interview with Terry Swack, which is making the blog rounds, emphasizes the importance of considering the uniqueness of positioning sustainable products:

"...most consumers still don't see the environment as a problem. Marketers have to help them not only to understand the problem, but to actually care about it. It's a matter of making it personally relevant and that their actions matter. But even the greenest consumers don't use sustainability as their primary decision criteria. The green product has to work as well or better than as the other, and be priced relatively the same. Then they'll look at the green attributes."

In other words, a sustainable product not only needs to provide comparable cost, functionality and ease-of-use, but also has the added imperative of effectively communicating its value above and beyond traditional product alternatives. 

How is one to accomplish that?  Since we're talking about attributes that go beyond the user's short-term engagement with the core functionality of the product - like its impact on the environment -  I believe it is most effective to take a service design, rather than a product design approach.  In service design we are not only interested in the ease-of-use around the product, but the user's holistic awareness and experience. 

In a service design analysisI conducted last year, I defined three key characteristics of a service experience:

• Guidance - Information delivered to service consumers to learn about the
  service, understand how to use and navigate the service, and to take
  away for reference.
• Comfort  - Transitioning to physical, emotional and cognitive ease and
  familiarity is necessary for services that take place in new contexts or
  locations.
• Sensation Excitement, surprise and other emotional factors can attract
  interest and maintain engagement over the duration of the service.

While these characteristics were used in the context of a multi-dimensional user experience (i.e. attendance at a design conference), they can also be applied to a user's experience with a sustainable product:

• Guidance - This refers to the educational component of the user experience.  Increasing the user's awareness of the relative value of a sustainable product, as well as it's appropriate usage, is (at least for the short-term). Implicit and explicit guidance needs to be factored into the design.
• Comfort  - On one level, users need to be convinced that the sustainable aspects of a product will not compromise their experience in terms of mental demand, physical comfort or other comfort-related factors.  At the other level, many users will feel a sense of satisfaction if they are sacrificing a degree of comfort in order to lessen environmental impact.  The design challenge is balancing those two types of comfort across different types of users, and even within an individual's range of experiences with the product.
• Sensation - Excitement can come in many forms, but perhaps none more tangible then the pairing of saving money while "saving the planet".  Many, but not all sustainable products can provide comparable functionality at a competitive or reduced cost. 

As with designing services, it's critical to mindfully combine these three characteristics.  One example is home power monitoring applications.   These interfaces provide explicit guidance via reporting energy usage for various appliances within the home, support comfort, quite literally, through effective temperature management, and deliver sensation through a combination of heightened user control and cost savings.

IDEA Winners in Design Resarch

2008 was a landmark year for the design research category of the International Design Excellence Awards, with a research project winning "best in show".   

SizeChina, the ergonomic data research project focusing on Asian populations won a Gold for the research category and is sharing best in show honors with the Apple iPhone.  SizeChina "assembled data from a representative cross section of people from mainland China to create the first-ever digital database of Chinese head and face shapes. Now, designers hoping to reach the two billion people in the Southeast Asian market will be able to create products that genuinely fit the needs of this audience."

I covered SizeChina last year after attending Roger Ball's presentation at the 2007 IDSA conference.

Coincidentally, the Silver winner (pictured) in the research category also has a Chinese connection - How the torch of 2008 Beijing Olympic Games came into being.  According to the site "this project's approach infused a sleek and modern design with symbols of both Chinese culture and the spirit of the Olympic Games", although it's not apparent what research was done to support this.

Bronze award winners included three medical-related projects, a field where user research is typically a critical component.  This year, the IDEA site not only lists the award winners, but all of the finalists, which range from color trends to condom dispensing projects.

You can also read more coverage of the awards at Businessweek, and learn about my experience as an IDEA juror this year (although not in the Research category).

Wall Street Journal Special Section on Product Design

I'm a few weeks late in reporting on this, but the WSJ had a very relevant section in the Monday, June 23rd edition, that you can access online.   Form and Function contains a series of case studies on recent product designs, ranging from golf clubs, to blue jeans, to power tools and even a Buick.

What each of these min-articles has in common is a focus on the role of user research, human factors and usability in the success (and sometime failures) of products. 

One of the more interesting examples discusses the MK Diamond portable masonry saw (pictured here).  It's a clear demonstration of what happens when you don't design for your users appropriately, and then learn from your mistakes.  And while I could argue the finer points of the described design research (e.g. risks of relying on focus groups for identifying requirements, using product designers as representative users, etc.), let's be happy with this sort of message getting across to a mainstream audience:

"The completed product, released in 2003, was an immediate hit, selling 3,120 units in its first year. But through customer feedback, the company began learning about design flaws in the BX3.

For example, the design assumed that most masons would operate the pull-down handle that brings the saw into cutting position with their right hand. It turns out, though, that masons typically grip the material they're cutting with their right hand and pull the handle with their left. That made the handle somewhat awkward for many users.

The company also realized there had been a critical flaw in its design process: It had conducted focus groups with contractors and suppliers who would buy the saw, but not the masons who would actually use it."

"After four years, MK Diamond decided to redesign the saw, and invited masons to its focus groups...designers became familiar with the BX3 by mimicking its everyday use -- carrying it around, transporting it in a pickup truck and cutting cement blocks. All that was videotaped and photographed, and the designers examined the images to help them find ways to make the saw easier to use.

One conclusion was that the saw folded in a way that required a mason to extend his arm outward while carrying it, causing shoulder strain. Tweaking the design, so the user could hold the folded saw closer to his leg, would make it seem lighter and reduce the strain"

BMW Redesigns i-Drive

In recent years the BMW i-Drive system has become the poster child for bad usability in interfaces (e.g. Don Norman's criticisms) - a conveniently-named foil to the positive user experience of the iPod.  But CNET now reports that a new version of the i-Drive (pictured) is in the works.  As a past user of the i-Drive, the new design seems to be addressing some of the key problems I experienced, with dedicated buttons for accessing each of the primary modes, and a single-axis rotary control apparently replacing key functions that previously relied on a multi-directional joystick.

Design Research and Sustainable Design

Mark Vanderbeeken (Core77) reports on the Changing the Change conference, which focused "on the role and potential of design research in the transition towards sustainability".  Design research can mean a lot of things, and in fact there were 138 papers presented on related topics.  Speakers included arch-IDEOer Bill Moggridge, who provided an "explanation of the three types of design research: generative, evaluative (or formative) and predictive, and his description of the Designers Accord, which is a powerful sustainability initiative spearheaded by some people within IDEO."

State of the Art in Interface Design

Coming Soon: Nothing Between You and Your Machine (New York Times) discusses the recent trends in direct manipulation interfaces in consumer products. The popularity of the Nintendo Wii and the Apple iPhone are in large part due to their intuitive user interfaces that utilize physical manipulation to give users a more direct feeling of control.  The re-emergence of voice control as a potential interface medium is also discussed.  The overall shift away from the point and click paradigm may be finally happening:

“I’ve wondered for a long time why the computer interface hasn’t changed from 20 years ago,” said Austin Shoemaker, a former Apple Computer software engineer and now chief technology officer of Cooliris. “People should think of a computer interface less as a tool and more as a extension of themselves or as extension of their mind.”

Back to the Future of Ergonomics

The first issue for 2008's volume of the journal Ergonomics is focused on the future of the field.  While an academic or professional subscription is required to access the volume, the lead article, Bartlett and the future of ergonomics, is available for free online. 

The article takes a retrospective look at Sir Frederic Charles Bartlett's 40+ year old predictions on the future of ergonomics, which were surprisingly insightful and accurate:

"Bartlett predicted that developments in automation and communication technologies were likely to present a significant challenge for Ergonomics. Specific predictions he made seem to derive from overall anticipated changes in working activities, and research foci, as a result of the new technologies. These were:

1. greater physical isolation of individuals;
2. greater demands on technologically-mediated communication;
3. reductions in physical workload;
4. increases in mental workload;
5. combining of the work of several people into the work of one;
6. presentation of multi-modal stimuli;
7. greater emphasis placed upon decision making; and
8. shorter working hours and more leisure time."

The article closes with a look at more recent predictions made by ergonomists, as well as design research practitioners:

"Fulton Suri (2001) proposed the adding of 'empathy' to the armoury of the professional ergonomist. She saw challenges arising from an ever widening field for the application of ergonomics, from resolving conflict between the commercial goals of organisations and the societal goals of maintaining human values and from trying to influence how systems are designed and operated. Fulton Suri saw the role of the ergonomist as being one of a centrally positioned facilitator of effective solutions through being more empathetic to the needs of all concerned."

Beyond this lead article, the content of the special issue contains articles on future ergonomics trends taken from the present context, presented by a range of international experts.  If these experts are nearly as accurate as Bartlett was about the future, then this is clearly worthwhile reading.

On a related note, the Human Factor & Ergonomics Society recently published an article, On the future of ergonomics, based on a survey of their members.  It includes estimates of the ergonomics job market across a number of relevant fields and industries.

Sketching:Designer :: ______:Researcher

If you've taken a standardized test you may recall analogy questions.  For example, if the problem posed was air:airplane :: _______:ship, a reasonable solution for the blank would be water (apparently this notation is called the Aristotelian format).

I started thinking about analogies after reading Carl Alviani's recent Coroflot posting - Questioning the Cult of the Sketch.  The article challenges the common view that strong sketching, or drawing skills, are critical for a designer, especially in the context of judging whether to hire a designer.  Alviani quotes a Creative Director at Nike: "A designer who can't sketch is like a journalist who can't write!".  Alviani's point is that sketching, which has traditionally been table stakes in the design industry, is now just one of many design-related skills - and arguably not one of the most important ones, compared to other forms of communication, management, etc.  A great designer need not be a great sketcher.

This got me thinking about the analogous skill to sketching in the design research field.  That is, what skill is considered so fundamental to conducting research that it would not only be possessed, but well-honed in experienced design researchers?  I made an initial, incomplete list:

• research planning
• observational aptitude
• note taking proficiency
• interviewing skills
• data capture competency (photo, video, audio)
• data synthesis and analysis

To narrow this down, I focused on those skills that had characteristics which were most analogous to sketching: early in the process, raw/unrefined, driven by personal interpretation and feel.  This led me to settle on a consolidated grouping of observing, interviewing and note-taking, that collectively we can call field research skills.

Now, turning back to Question the Cult of Sketch, can a great design researcher lack great field research skills?  I would think not - there is a critical distinction from sketching here - field research skills are intrinsically broader and multi-disciplinary relative to sketching.  One might be a weaker note-taker, for instance, but still excel with effective interview questions (and a good memory).

But perhaps Alviani and I are both asking the wrong questions because we are inwardly focused.  A more fitting question of the modern designer is - can you conduct research to inform your designing, and of the modern researcher - can you design to communicate your research results?  Otherwise expressed as research:designer :: design:researcher*.

*See Christopher Fahey's Design Research is a Design Process for an interesting perspective on these issues.

I.D. Magazine 2008 Annual Design Review Jury Experience

Last week I had the privilege of serving on the equipment category jury for the 2008 I.D. Magazine Annual Design Review (to be published this summer).  By way of background, I.D. has been conducting an annual review of the best designs for over 50 years.  This is something I had wanted to do since I read the magazine as a teenager (perhaps that says as much about my social life as my interest in design, but anyway).   Besides equipment, there are a range of categories including consumer products, interactive design, furniture, environment and graphics.  Consequently, the selected winners are not only considered the best designs, but represent the state of the art in each category.

Given my background, I saw my responsibility as focusing on the ergonomic aspects of each of the nearly 50 products we reviewed.  My sensitivity to usability was heightened by staying in a New York hotel room the preceding night where the temperature controls were reversed.  Unable to get my $300 room warmed-up, I later found out that, due to some technical fluke, I had to set the control to cold to activate the heat.  This also meant lowering the thermostat to below the current room temperature so that the "cold" would switch on.

Fortunately, it turned out that my co-jurors who are designers/design teachers had as much to say about human factors, as I did about aesthetics.  By its nature, the equipment category tends to evolve gradually, compared to the more dynamic year-to-year changes of interactive or even consumer products.  The Annual Review issue will be published in a few months, so I can't go into details on the entries at this point (see the 2007 Annual Review for reference), but by participating in the judging process, I did learn or confirm some principles about what makes a successful entry. 

The judging process is based on expert review and consensus - in other words the criteria changes from year to year based on the expertise, opinions and criteria of the particular judges in each category.  At the same time, the nature of the judging process - one full day of going through a large number of entries - suggests the following to submitters:

1. Treat the Entry Process Like a Design Project: Successful designs meet the needs of their users.  In this context, the users of the entry forms are expert designers and their tasks are to relatively quickly review and classify submissions.  Design basics like appropriate use of typography and visuals to communicate information quickly and effectively are critical (one would think this would go without saying).  In other words, given two hypothetically equal design submissions, the one with the well presented, visually structured entry may get more attention than the scribbled one.  This may mean going above and beyond the constraints of the entry form, where appropriate. 

2. Communicate to a Naive Audience: While jurors are experts in design, they can come from a range of industries and backgrounds.  The equipment category in particular, includes a variety of complex, technical products that may be unfamiliar and require explanation.  Explanations should include a scenario to describe when, how and why such products are used.  In some cases, videos can illustrate usage with a demonstration or simulation.  Similarly, it is valuable to explicitly communicate why a particular product is an improvement over competitor or predecessors, as jurors may not be knowledgeable of particular domains.

3. Link the Product to the Greater Design World: Jurors are not only looking at the inherent strengths of a particular design, but how it fits into the current, changing design world (re:  my earlier comment about the Annual Review representing the state-of-the art). Consider that two well-designed products from completely different fields need to be compared against each other - broad, less tangible factors such as symbolism of emerging design trends,  or benefits to society and the environment may come into play.  This is not an easy area for the submitter to address, but I suggest considering the ramifications of a design to the field of "Design", as well as a product's specific users and industry.

I look forward to discussing the Annual Review issue when it comes out.

Human Factors in Mechanical Engineering

February's issue of Mechanical Engineering is focused on the role of human factors in design.  The lead article, the new point of view, discusses the renewed importance of human factors in product design, with a veritable who's who of IDSA experts in the subject, including Don Norman, Rob Tannen and Bryce Rutter.

The article is a useful introduction targeted at an engineering audience, and covering the wide range of human factors aspects, from physical fit to creating an emotional connection with the end-user:

"More than ever, successful companies incorporate human factors engineering, psychology, and cognitive theory in designs. Their goal is nothing less than to create a user experience that makes us love the product."

The issue also contains a focus on use - an article on the importance of collaboration between designers, researchers and engineers in creating usable products, and a video of a human factors discussion panel moderated by Don Norman.  Accessing the video requires filling out a brief registration form.

Finally, ME magazine is clearly putting its money where its mouth is, by launching the human factors articles in conjunction with a nice upgrade to it's web site design.

CES and Bug Labs

 

While I was not able to attend the Consumer Electronics Show this year due to other work commitments, all reports indicate that it was bigger than ever.  As expected, a number of high performance, high definition videocameras were announced, featuring researcher-friendly capabilities including larger capacity hard drives, image stabilization and greater optical zoom ranges.  I'm somewhat partial to the new JVC Everio line from a styling point of view, especially the top of the line GZ-HD7.

But beyond the typical consumer product lines, one product stood out and even took the Best of CES award for the emerging technology category.  That product is Bug Lab's Bug, described as a:

"collection of easy-to-use electronic modules that snap together to build any gadget you can imagine. Each BUGmodule represents a specific gadget function (ex: a camera, a keyboard, a video output, etc). You decide which functions to include and BUG takes care of the rest letting you try out different combinations quickly and easily. With BUG and the integrated programming environment/web community (BUGnet), anyone can build, program and share innovative devices and applications. We don't define the final products - you do."

In other words, a set of modular consumer electronics components that can fit together and then be custom programmed to do whatever the user/developer desires - open source will help with that a lot. 

The current set of modules include an LCD display, a camera, GPS and motion detector - all to be released this quarter, with second quarter modules including a touch screen, keyboard, and audio module.  Check out some videos on YouTube.

These components represent a promising set of opportunities for user and design research:

• Create custom data gathering devices and programs to conduct observational research (camera), time and motion studies (motion sensor, GPS), etc.
• Develop custom products and user interface prototypes for testing using the hardware and software capabilities

The quality of the hardware (e.g. video image quality, motion detector sensitivity) and the ease and flexibility of the development environment will be key of course, but I look forward to the possibilities that BUG may enable for the creative designer/researcher.

Featured in IDSA designperspectives (and happy 8th birthday to us!)

The recent update to the DesigningforHumans site was covered in the December 07 issue of IDSA designperspectives.  The page 3 blurb, titled "A Blog for Joe and Josephine", briefly describes some of the recent changes to the site. 

Here's some additional detail above and beyond what's covered in the article:

I created the original IDSA Human Factors section site in 2000 (!), but at the time it was somewhat of a hassle to keep it current due to the available web editing technologies and it didn’t last very long. You can actually still access the home page circa 2000, although most of the links have rotted: http://www.idsa.org/whatsnew/sections/hfactors/

In January 2005 I restarted the site as a web log (aka blog) format because that accommodates quick entry of short to medium pieces of information that I could update frequently. It also allows people to subscribe to updates via email or RSS feed.  It’s been going strong since then with page views increasing by 100%+ in every year since 2005.

A large part of the audience is international and non-IDSA, who use the site for reference info on human factors issues (it’s ranked pretty high for relevant human factor searches in Google and elsewhere)

Usability and Aesthetics

In a New York Time's Magazine* Consumed article, Rob Walker discusses the IDEA award winning HomeHero fire extinguisher.  The product is notable because unlike traditional fire extinguisher designs, the HomeHero is clearly designed to be attractive .  More than just an aesthetic issue, the argument is that making such a product visual appealing will influence owners to place it in a visible and presentable location - thereby improving access and speeding up time to use in a fire.  So there's an interesting concept on making products (at least or especially safety products) attractive to promote their accessibility and enhance user situational awareness.  [Incidentally, Walker points out that the IDEA judging is not based on direct experience with the actual products, but rather images and descriptions submitted by the entrants.]

On a related point, Walker mentions Don Norman's idea that "attractive things work better".  (Incidentally, this is frequently confused with the Aesthetic-Usability Effect where attractive things are perceived as easier to use.)  I bring this up because I imagine the HomeHero's simple, clean aesthetic is perceived as easier to use, but I doubt that its perceived to work better.  Rather, it may be the case that traditional fire extinguishers, while less attractive in a designer's aesthetic sense, have an industrial appearance that may more strongly communicate effectiveness to the consumer.  In other words when we discuss "attractive" or "aesthetic" qualities, we need to qualify what we mean in the appropriate context. 

*Incidentally - if you read one issue of the New York Times Magazine this year.  This should be it.  It's the "Annual Year in Ideas" - a summary of the most interesting and provocative inventions, theories, studies and concepts that emerged in 2007.  Everything from an airborne wind turbine to Radiohead's music pricing approach.  And the back-page listing of some of the year's strangest patents (e.g. a chewable toothbrush).

Eight Design Research Themes for 2008: Technologies and Methodologies

2007 has witnessed the continued maturity of user research practices in product design/development organizations. As this continues, we look to 2008 and key areas of growth and change in user research technologies and methodologies. What many of these themes have in common reflects a shift from how to conduct research, to how to manage all of the research findings and results – clearly a positive trend and a nice problem to have.   Stay tuned into 2008 as these themes are tracked in further detail.

Technologies

Even a casual reader of this web log will have observed the ever-growing options in data gathering technologies available for a variety of research applications. For 2008, the themes in technology are diverse – from high definition video to a new resource of anthropometric head measurements of the Chinese population. But the more compelling tools address needs in organizing and analyzing qualitative data:

1. High Definition (HD) Video- HD video cameras are rising in popularity while falling in price. Higher resolution video means larger file sizes and typically more time for video editing and file management. On the other hand, greater visual clarity can be extremely valuable for studying fine motor control tasks, small control/interface element usage and visually-rich environments. Surgical observation and consumer electronics usability are two applicable areas for HD video.

2. International Anthropometric References – Much of the reference anthropometric data used to guide designs is based on the body dimensions European and North American populations, limiting applicability and, ultimately fit, to a broader user population. The availability of three-dimensional scanning technology, while still time-consuming and expensive, is driving the inclusion of additional populations. Size China is a program to create the first-ever digital database of Chinese head and face shapes for helmets, sunglasses and surgical masks. Such resources will provide a richer starting point for guiding form and size in product designs, but of course are not a replacement for fit testing with real participants.

3. Qualitative Data Management Software – As research capabilities mature, organizations will deal with a new set of challenges around handling larger volumes of research data. Research teams will struggle with organizing, presenting and efficiently re-using findings across projects. With that “embarrassment of riches, there is a need for techniques and tools that support research data management. For example, QSR Internationals’s forthcoming NVivo 8 provides a structure for entering, tagging and querying various forms of multimedia, qualitative data across multiple projects. These types of tools will enable more effective collaboration amongst both localized and geographically distributed researchers, and can provide a centralized repository for observational data.
4. Qualitative Data Analysis Software – The value of well-conducted research is extremely limited if it is not easily organized for effective communication. It is especially challenging to organize, analyze and interpret qualitative data such as user interview transcripts and observational field notes. Following many years of adapting general purpose software and technology, we now have access to a variety of software and hardware tools to support planning, collection, analysis and sharing of research data. Several new technologies can support unstructured data analysis in various ways including searching speech via text and syntactically mapping information. For example, IBM’s Many Eyes application visualizes text in a tree-like branching structure to enable more efficient analysis and data mining.

 

Methodologies

Design research methods will continue to adapt for studying the wider range of user experiences, beyond the primary product. Frameworks and techniques for mapping out user touch points will assist research planning, which will become specialized to particular domains (e.g. medical vs. consumer). Threading across all of this is the need for guidelines for effective research communication and presentation:

5. Comparative Ethnography - While many organizations are using ethnographic observation to understand end-user perspectives and stimulate innovative thinking, such research is frequently focused on a limited set of tasks and users. But a growing trend is to use ethnographic methodology to identify differences between contexts. For example, in a study of automobile driving behavior, Bresslergroup’s research plan not only focused on the in-car driving experience, but studied related, non-driving activities. Observing how comparable tasks (e.g. planning a route, choosing music to enjoy) are conducted in disparate contexts (in this case, in car vs. in home) provides unique insights to inform creative solutions.

6. Service Design - Beyond the “total product lifecycle” approach, organizations will need to understand where they fit within the range of loosely tied user experiences beyond the product itself. For example, medical implant designers should expand user research beyond surgery to understand the touch points that potential patients, caregivers and healthcare providers utilize to make treatment decisions, prepare for surgery, and deal with recovery and beyond. The emerging discipline of service design provides a framework for understanding how multiple types of providers and users interact across the various products, interfaces and environments where interactions and decisions occur.

7. Domain-Specific Research Methods – Although research practices can vary among domains (e.g. medical, consumer, industrial), core methods remain consistent. But as research teams mature, there is a movement towards industry-specific user research and design techniques. For example, in appliance design, usability testing with high-fidelity simulations is frequently necessary to elicit reliable performance feedback from consumers. By contrast, healthcare professionals are typically more capable of responding to lower-fidelity prototypes, partly attributable to their professional problem-solving processes.

8. Presenting Design Research – Typically, product development organizations can effectively present and communicate their work and capabilities in design and engineering. But even when products are backed by quality user research, teams may struggle with effectively communicating its influence on product design. Similarly, organizations have difficulty evaluating the research capabilities of potential employees. The Industrial Designers Society of Americas (IDSA) is leading the way in developing guidelines for design research presentations, starting with the organization of design research portfolio workshop & review at the Northeast District conference this April in Philadelphia.

Bang & Olufsen: Great Designers vs. Great Process

This past week's Businessweek contains an interesting article about the design process at Bang & Olufsen.  Bang & Olufsen: Design Reigns Supreme describes what might be called the "great man" theory of design, where design vision takes precedence over engineering and business, and does not include design research. This "model is a throwback to an earlier time when CEOs worked closely with gifted designers to differentiate their products in the marketplace".

While B&O is clearly a leader in aesthetic design of consumer electronics, they have been failing at making the transition to the digital world (e.g. from CDs to MP3s).  And it's evident from reading the article that this is partly attributable to the lack of a research process:

"They don't, for example, do even the basic market research ethnography common among consumer-oriented companies. Sorensen says consumers often don't really know what they want. Instead, B&O designers intuit the products that will fly."

Read between the lines and it's apparent that there's a lack of understanding about design research.  Ethnography is not about asking consumers what they want, it's about identifying their unmet needs, a very creative process in itself.  Later in the article there's a likely example of what happens when you rely on designer intuition:

"Take the digital music player. Even the company's loyal cognoscenti prefer Apple's iPod, with its elegant design and easy interface, to the $460 BeoSound 2--conceived by none other than Lewis in 2002. BeoSound 2 has been, by all accounts, a dud. Lewis says his mistake was not appreciating how quickly digital memory would grow. He figured with 50 songs on a device, the amount the original memory card would hold, consumers wouldn't need a screen to navigate through their music."

Perhaps if Lewis and his team had better understand their user audiences - typically high-net worth music lovers - it would have been discovered that 50 songs was not going to meet their needs long terms and a different design approach would have been more successful.

Of course hindsight is 20/20 and B&O is shifting its focus to bringing in designers who understand the digital world. Unfortunately, it appears that they're still missing the point - they don't so much need new designers, as a new design process.

Human Factors of nonobjects

The release of branko Lucic's forthcoming design fiction book, nonobject has been moved from late 2007 to early next year.  This seemingly fascinating book is about:
" deliberately creating objects that cannot exist -- because the material is not yet available, or the business plan, or the manufacturing process, or the infra- structure to support it, or even the human sensibility -- it becomes possible to explore the meaning of design at a more profound level and to think more richly about what is and what might be."

In addition to a penchant for starting proper nouns with lowercase letters, Lucic's four initially available concepts and videos emphasize communication, with two versions of cell phones - the CUin5 (pictured above) and the Tarati (pictured below).  I recommend viewing the videos about each of the design concepts before reading further to get a clearer understanding.  At his presentation at Connecting '07, Lucic previewed some to-be-released concepts as well including a motorcycle design, which will presumably be available online at a later date.

In the spirit of intellectual/conceptual thought, I started thinking about these nonobbjects for a human factors perspective.  One of my first realizations is that while these are conceptual product designs, the concepts that are strongly human-centered.  I don't know whether or not ergonomic and usability aspects of these concepts will be discussed in the book, but here's my take with respect to the two phone concepts - based on the limited information currently available:

CUin5
This concept might best be described as the anti-iPhone.  While Apple's device is all about screen size and minimal buttons, the CUin5 is literally all buttons and no display.  Multiple sets of numeric keypads are provided on all six sides in different arrangements and orientations.  The foreseeable human factors aspects of this include:

• Ability to "dial" the phone without re-orienting it.  In other words it may be used immediately whichever way the device is facing when you pull it out of your pocket or pick it up.
• The large, clearly visible and tactile buttons would lend the device well to use by individuals with visual and motor limitations.
• Single-handed and multi-finger dialing.  For example, when holding the phone in the palm of one hand, the user could conceivably use all 5 digits in their resting positions to access the buttons on the various faces of the device, perhaps somewhat analogous to holding down different strings on a guitar.  Compare this with the relatively laborious current process of holding the phone in one hand and selecting buttons in sequence with a single finger.  Similar benefits might be applicable to text messaging as well - were there a display for reading messages.
• At the same time, the presence of buttons across the device suggests a risk of inadvertently pressing buttons.  This could be addressed by finding an appropriate resistance for the buttons (which may vary from face to face) as well as a lock-out feature.
• The lack of a dynamic display would suggest that the phone would have limited functionality compared to current smart phones. But this might be fine by many people who just want a phone that works well as a phone. And some features (e.g. address book) could be handled through interactive voice functionality.

Tarati
If CUin5 is all about maximizing tactile connection with a phone, the Tarati is about minimizing it.  A very thin design is accomplished by removing all buttons and replacing them with spaces for the user's finger to pass through while dialing.  A dynamic digital display, in conjunction with dial tones, provides feedback on actions.  From a human factors perspective, several issues are worth considering:

• The lack of tactile feedback when "pushing" buttons is probably not a problem for most users, given the familiarity of the keypad arrangement, the audio/visual cues and and procedural or muscle memory that we have for using phone keypads.  One case where it may be a bit of an impediment is when dialing consecutive numbers - tactile feedback is more important here as it let's the user judge when to reverse the application of force from withdrawing to re-pressing.  The effectiveness of this in Tarati will largely depend on the sensitivity, distance, and timing of the sensing system.
• It's not clear whether the lack of visible and tactile buttons would automatically be an impediment for users with limited vision and/or motor skills.  For example, the lack of visible button labels is of no consequence to blind users, and the fact that no force is required to depress a button may make use easier for some people.
• Minimum finger dimensions, particularly circumference, would need to be accounted for in the size and shape of the insertion points to accommodate use with large fingers without getting scraped by the edges or stuck - not to mention long fingernails.
• A device with openings such as this is likely to collect dirt from both use and lack of use - so cleaning and maintenance are important factors.

Usability of Videogames

The cover story of the current issue of Wired magazine (15.09) discusses the user-centered approach to make an upcoming game playable.  Halo 3: How Microsoft Labs Invented a New Science of Play focuses on the work of Randy Pagulayan and his team at Microsoft, who conduct usability testing and analytics to optimize game play - for example, when an area of the game might be too difficult, or a key weapon overlooked by too many players. (Note - Randy is a grad school buddy of mine from University of Cincinnati - I've personally visited his lab and its quite impressive in terms of technology and methods).

I'm also trying out a new feature on the IDSA Human Factors site called Snap Shots, which displays a preview of a linked site on rollover.  Let me know if it's more useful than annoying or vice versa.

RedesignMe.org - The YouTube of Usability?

http://www.redesignme.org/ is a Flash-based beta site where anyone can post video, photo and text of a product with usability problems.  You can also add comments to other people's postings (down with OPP?), ratings, and most importantly, post your own design solutions in image or video format.  The goal of the site is to "promote simplicity in product design" and give "a signal to industry".

The site has a friendly, comic-book feel, although is a bit navigationally clunky.  For example, when I submitted a new example (poor placement of the volume control in the Mini Cooper), I had to refresh the site following submission to view my entry.  And when viewing a full-size image I had to negotiate three vertical scrollbars at one time. I also can't send you a direct link to my posting.   Let's chalk it to growing pains - it is a beta, so please don't submit the site as a self-referential product example.   A simple registration is required to submit content.

This site is a great idea - a slicker interactive update on classics like http://baddesigns.com/

The Future of "User-Designed"

Core77 is featuring an article about a collaborative project between Ignition, Texas Instruments and Southern Methodist University students/users to design next-generation digital projectors. 

In, The Future of "User-Designed": How one company worked with end-users to design their perfect product, by Bryan Hynecek, ininitial design concepts were created by gaming users - in this case master's students in video game development - and then reviewed and improved by the professionals. 

One might question whether using master's students in game development is truly "user-centered" in the sense that these might not be considered novice users.  On the contrary, I applaud the selection of a targeted, expert end-user sample who have clear interest and motivation, but are by no means product designers.  Decide for yourself.

"Female-Friendly" Design

A recent New York Times article discuss some of the trends in designing technology products to be more appealing and/or more usable by women:

To Appeal to Women, Too, Gadgets Go Beyond ‘Cute’ and ‘Pink’

Though anecdotal, the article makes the point that product designers are feminizing technology to give it a broader appeal, rather than creating specifically masculine or feminine specific products.  In the case of technology these typically lean towards masculine designs by default.

MIT Technology Review - The Design Issue

Update (7 May) - The article on the Helio Ocean phone discussed below is now available online, at least temporarily:

http://www.technologyreview.com/Infotech/18648/

I've mentioned MIT Technology Review magazine before as an excellent resource for keeping up with emerging technologies, design-related and otherwise.  Well, the May/June 2007 issue is focused on design, with an emphasis on user-centered design and technology.  Articles of interest include:

• case study of the forthcoming Helio Ocean smartphone, specifically the human factors and related mechanical engineering challenges of creating a multi-function mobile device
• discussion of Apple's industrial design process and advantages
• an interview with Bill Moggridge (IDEO)

Note the magazine print edition is currently available, but will be available online in the coming months.  You can actually view the issue's table of contents here, but the article links are not functional yet:

User-Driven Innovation

Yesterday's NY Times business section (free registration required) included a brief article titled:  How to Improve It? Ask Those Who Use It.  The article discussed the rising use of user-driven innovation, where companies are receiving input from customers on the design and customization of their products. 

Unlike user-centered design which incorporates end-user input into a company's internal design process, user-driven innovation is externally motivated.  For example, a company may adapt a customization made by a current product user into the next version of its product. 

The article discusses how this has happened for a particular medical device manufacturer, and touches on the logistical and legal challenges to this approach.  For additional information, the article refers to Eric Von Hippel's Democratizing Innovation, which can be downloaded as a PDF.

Human Factors Product Design Award

Two medical devices are the winners of the 2006 User-Centered Product Design Award. Submitted entries are judged in terms of application of Human Factors process and the effectiveness of the resulting design.  There was actually a tie this year between two medical devices:

http://www.hfes.org/web/DetailNews.aspx?Id=116

The winning devices are the Medtronic Straightshot M4^TM Microdebrider and Hospira's Symbiq™ Infusion System. Contributing to the winning designs were Metaphase Design Group (Straightshot M4 Microdebrider) and HumanCentric Technologies, Inc. (Symbiq Infusion System).

As a committee judge I can tell you that the overall quality of entries has increased over the years, a sign that HF and user-centered design has a growing presence in industry.

Cooper-Hewitt People's Design Award

New York's Cooper-Hewitt museum has a number of design events going on:

• People's Design Award - You can view, nominate and vote (although it doesn't count) for your choice for the annual award.  Frankly, the site itself is poorly designed: it's not clear that there are many more award nominees than then six visible on the home page, and there's no place for a collective list. Still a nice summary of great designs from the past and present.
• National Design Week - October 15-21 2006 is National Design week, with free admission to the museum.  This week will include the announcement of the National Design Award winners.
• National Design Triennial - From December 2006 though July 2007, the museum will host "experimental designs and emerging ideas—including animation, new media, and fashion, robotics, architecture, product, medical, and graphic design—at the center of American culture from 2003 to 2006."

New User Interface Technologies

It was an eventful week in the field of user interface control design. Two new technologies were announced by industry leaders Synaptics and Logitech:

• Synaptics announced the Onyx phone concept - a concept platform for a new touchscreen technology.  Touchscreen control on mobile devices is nothing new, but the Onyx technology recognizes  more than just single touchpoint inputs.  It can identify natural behavioral patterns and gestures - for example the profile of a user's face as an indicator that the user is ready to answer an incoming call.  This can reduce interaction to basic gestures rather than deliberate controls.  It also makes the device extensible to a wide range of activities (e.g. phone, music, messaging, etc.).  It will be interesting to see who this potential is realized in the design of devices in the near future. 
• Logitech is launching a new computer mouse (MX Revolution).  The key innovation in this product is a new type of scroll-wheel that spins with less friction, along the lines of a flywheel.  This enables the user to scroll more quickly and with less effort compared to standard scroll wheel designs.  This change in function will require an adaptation in user behavior to adjust to this new method of scrolling.  As with the Synaptics Onyx, it will be interesting to observe the extent to which both product designers and consumers adapt to the potential benefits (and drawbacks) of new human-computer interaction technology.

"Get out of That Rut and Into the Shower" discusses the business advantages of conducting field research to understand customer experiences and product usage.  The article emphasizes the value of field observation over traditional marketing methods (e.g. focus groups) for identifying unexpected opportunities for innovation.  Design firm Continuum's research on how people take showers is cited as an award-winning example.

Innovation: Design Research

The Summer 2006 issue of the IDSA quarterly, Innovation, has just been published.  This issue is of particular interest because it features eight articles representing a range of perspectives on design and user research.  Three articles of particular interest for Human Factors advocates:

• Digital Ethnography Sparking Brilliant Innovation - Darrel Rhea, IDSA and Lisa Leckie - Discusses the role of digital consumer technology as a means to for users to capture and deliver self-report research from the field.
• The Integration of Industrial Design and Human Factors Bricks & Mortar - Barry H. Beith, PhD and Joseph Jasinski, IDSA - Provides a discussion of how Industrial Designers and Human Factors experts can work together effectively.
• The Future of User Research Ubiquitous Computing - Rob Tannen, PhD, IDSA - Posits that many of the constraints of current research methods may be overcome through the development of product usage measurement technology.  You may download Tannen's artice:  innovation_tannen.pdf.

Note - IDSA typically publishes a few of these articles online.  The journal site has not been updated as of this posting (it still features the Spring 2006 issue), but when the Summer issue is posted, we will post a blog entry with the specific links.
