Title: The Design of Everyday Things by Don Norman Description: One of the world's great designers shares his vision of "the fundamental principles of great and meaningful design", that's "even more relevant today than it was when first published" (Tim Brown, CEO, IDEO). Even the smartest among us can feel inept as we fail to figure out which light switch or oven burner to turn on, or whether to push, pull, or slide a door. The fault, argues this ingenious -- even liberating -- book, lies not in ourselves, but in product design that ignores the needs of users and the principles of cognitive…
