Interview with Dan Saffer
I've started a new blog for long articles about the design of products called Designing Devices. I'd like to turn them into a book one day, but for now they're just a free blog for your enjoyment, so happy reading!
Some excerpts you might enjoy:
Other new chapters include Design Strategy (Chapter 3); Design Research Analysis (Chapter 5); and Prototyping and Development (Chapter 8). Most of the rest of the book has been substantially re-written. All in all, I feel it's a much better introduction to the field than the first edition. (First edition readers: contact me and I'll be happy to send you the Design Strategy chapter as a pdf for purchasing the "Beta" book!)
