Industrial design is something that should be more widely taught in engineering courses. My favorite book on the subject is "Turn Signals are the Facial Expressions of Automobiles". (Yes, that's the real title) "Things that make us smart" and "Emotional design" are also good. Affordances are a good example: What's on top of your washing machine and dryer? If they are front-loaders, then I imagine there may be a fair amount of "junque" piled on top. The manual of course tells you that you shouldn't pile anything there, but the large flat surface creates an affordance for piling junk on top. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
