“Designing Interactions gives access to a very detailed and adept summarized history of commercial interaction design. It’s an invaluable resource to anyone who wants to know what happened to get us to this point, especially with the computer interfaces. But, again, it does beg the question to be answered, ‘Why did these few people have such an effect, something that more designers producing more varying designs could have had?’” (Clifton Evans – Boxes and Arrows)
