Designing for Humans

in the cards

You may already be familiar with IDEO's Method Cards, which succinctly show & tell 51 methods for conducting research and design.  The cards tend to emphasize ways of thinking like "Look" and "Try", rather than specific, concrete methods.

Enter design consulting firm nForm with their own set of "user experience trading cards".  These provide more tactical methods, apparently focused on UI design, with cards for "Ethnography" (pictured), "Taxonomy" and "Usability Capture Software".

The IDEO cards are probably more valuable due to the greater diversity of ideas presented (although they do overlap internally in some cases) and are more of a way to think about a problem; whereas the nForm cards are more of a primer to user-centered design methods.  And the IDEO cards are tangible in a more important way - you can order a set of actual cardsfor reference and sharing.

Ergonomics, the Elderly and Elevators

A couple of interesting articles related to design and ergonomics in the past week:

-Businessweek had a blurb on Nissan's efforts to design cars for the elderly by wearing a restricting body suit (see image).  Although Bw was not the first one to report on this, and in fact other designers have previously developed similar simulation techniques, I really liked this illustration.  See, "How to Drive Like and Old Guy"  fourth image in slideshow. 

-In an unrelated piece, The New Yorker magazine featured an article "Up and Then Down: The lives of elevators",  While intrinsically interesting to anyone who rides elevators, ergonomists and designers will find the discussion of "proxemics" particularly fascinating from both psychological and anthropometric perspectives:

"Bodies need to fit. Designers of public spaces have devised a maximum average unit size—that is, they’ve figured out how much space a person takes up, and how little of it he or she can abide. The master fitter is John J. Fruin, the author of “Pedestrian Planning and Design,” which was published in 1971 and reprinted, in 1987, by Elevator World, the publisher of the leading industry magazine, Elevator World. (Its January issue came with 3-D glasses, for viewing its best-new-elevator-of-the-year layout, of the Dexia BIL Banking Center, in Luxembourg.) Fruin introduced the concept of the “body ellipse,” a bird’s-eye graphic representation of an individual’s personal space. It’s essentially a shoulder-width oval with a head in the middle. He employed a standard set of near-maximum human dimensions: twenty-four inches wide (at the shoulders) and eighteen inches deep. If you draw a tight oval around this figure, with a little bit of slack to account for body sway, clothing, and squeamishness, you get an area of 2.3 square feet, the body space that was used to determine the capacity of New York City subway cars and U.S. Army vehicles. Fruin defines an area of three square feet or less as the “touch zone”; seven square feet as the “no-touch zone”; and ten square feet as the “personal-comfort zone.” Edward Hall, who pioneered the study of proxemics, called the smallest range—less than eighteen inches between people—“intimate distance,” the point at which you can sense another person’s odor and temperature. As Fruin wrote, “Involuntary confrontation and contact at this distance is psychologically disturbing for many persons.”

Data Visualization of Qualitative User Research

While it is extremely important to gather qualitative data such as user interviews, it can be difficult to make sense of such ‘unstructured information’.   Often the biggest challenge is knowing just where to start.  For example consider trying to make sense of the transcriptions from several dozen user interviews - you might have a mix of positive and negative feedback, anecdotes, opinions and narratives.  You could painstakingly sift through all of the conversations, highlighting meaningful terms or search for keywords.  

But data visualization tools, typically thought of in terms of quantitative data, can also help to understand qualitative information.  Data visualization has been promoted as an effective means to present data, but its enormous value in analyzing data has been largely overlooked. 

One such example is IBM’s Many Eyes.  While this web application set is known to many for its beautiful graphing capabilities, I find the text visualization tools most valuable for analyzing qualitative data.  In particular, the Word Tree in Many Eyes “lets you pick a word or phrase and shows you all the different contexts in which it appears. The contexts are arranged in a tree-like branching structure to reveal recurrent themes and phrases.”

When applied to qualitative data (e.g. interview transcripts, free-text survey comments), the Word Tree allows a researcher to quickly scan through text-based content by searching via keyword or phrase.  For example to see what a group of users said about a particular product feature, the researcher can create a word tree around the feature (e.g. “portable” or “installation”) or around particular terms that are likely to indicate problems (e.g. “difficult to”, “but”).  

Visualizing the interviews around critical terms provides a starting point for reviewing and understanding qualitative data in an efficient manner.  It is not a substitute for thoughtful analysis, but a head-start. 

Note: One significant caveat in the case of Many Eyes is that all submitted data is publicly viewable, so it’s not always suitable for proprietary data analysis – but it is free.

"User Anthropologist" Article in NY Times

There's already a lot of buzz about the April 13th New York Times Magazine article that prominently features the role of field research to inform design.  Can the Cellphone Help End Global Poverty? follows Nokia researcher Jan Chipchase in Ghana.  While the article is great for introducing the benefits of corporate user research to a mass audience, it is also tactially valuable in describing some of the field research and design techniques employed by Nokia.

For example, even when apparently traveling light, Chipchase relies on high-end reliable equipment:  "Pretty much wherever he goes, he lugs a big-bodied digital Nikon camera with a couple of soup-can-size lenses so that he can take pictures of things that might be even remotely instructive back in Finland or at any of Nokia’s nine design studios around the world."

Nokia not only conducts field research for gathering information, but a form of user-driven field design:

"Nokia’s temporary design studio sat in a rented two-room concrete hut at the intersection of two busy dirt lanes, across from a woman selling chunks of watermelon and peeled lemons and next to a large water tank labeled “Church of God.” There was a sheet of fabric strung up in front, with neat painted lettering that read: “Your Dream Phone. Share it with the world.” It went on to describe how the community was invited to come share ideas and drawings for the ideal mobile phone. Prizes were offered. So far, 140 people had shown up to sketch their dream phone."

And on-the-fly feedback on product concepts: "Each time the group stopped to chat with someone, Burns pulled out several prototypes — or “physical sketches,” as he called them — for potential phones, handing them over one by one for examination."

Overall, the article validates that common user research techniques done in context, can provide revealing information to drive design.

Recap: Design Research at IDSA Northeast District Conference

While design research wasn't the overall theme at this past weekend's northeast district conference, it was certainly a prominent part of it.  On Saturday, Marty Gage spoke about the how to better communicate design research findings to designers - focusing on the essential transition between research findings and design solutions.  And research was wide-awake on sleepy Sunday.  We had our two-parter (panel/portfolio review)focusing on design research:

During the morning panel discussion, Art Swanson discussed the value of data visualization as a way of presenting information to clients.  Visualization, as opposed to analysis, presents data in an unfiltered, interactive manner to allow people to draw their own conclusions.  He suggested wefeelfine.organd gapminder.org as a couple of interesting examples of data visualization.

Sunmee Kim spoke next, focusing on the various aspects of a design research project at Motorola.  She finished by discussing an internal tool used by all of the design researchers around the world at Motorola to document and share data.

And Marty Gage appeared again, combining clear tactical advice with humor in discussing what should go into a design research portfolio.  It should be an extension of your design portfolio (if you have one), but is about meaning, not sexy imagery.

Following some great Q&A with the speakers, we had the first design research portfolio review, which was combined with the overall portfolio review (see photo above, courtesy of Core 77, and some more photos from that session).

My initial feedback on participating in the research portfolio review was that while there weren't many examples of detailed research projects to review,  it was useful to have professional researchers giving input to design students.  I'd love to hear feedback from other reviewers/reviewees, so please feel free to add your comments.

NY Times Review of Casio High Speed Digital Camera

Following up from my preliminary posting on the Casio Exilim Pro Ex-F1 high speed digital camera.  Last week, New York Times technology writer David Pogue, wrote a detailed review of the unique camera, including pointing out some limitations and constraints (e.g. light sensitivity, focus speed).  But Pogue is clearly impressed, suggesting that "it does seem ungrateful to criticize such an astonishing camera; it’s like complaining that your 7-year-old violin virtuoso is lousy at sports."

Pogue's article indicates that the camera will be available by mid-April.  I impatiently ordered one from Japan, where it was released at the end of March.  I should have in hand in a few days, so stay tuned...
