DFH Follow-Ups

Here's some follow-ups on several items I've blogged about in recent months:

• Redesigned BMW iDrive: The New York Times reviewsthe improved user interface (including rotary text entry, pictured above) and control system for the storied design failure that I discussed most recently in July.
  

• Design Research Blog: Sam Ladner provides a new article and slide set discussing Qualitative versus Quantitative Research (part 2) on her blog.  I discussed a couple of her earlier posts on design research back in June.

• Design Research Portfolio Review: Last, but not least, following up from this past April's IDSA northeast district conference, Marty Gage (Lextant) has provided his presentation slides for his talk, What is a Design Research Portfolio? - Download Research_portfolio_final(PDF).
