This book takes a lighthearted look at the very serious business of designing simple (and not so simple) everyday objects. The principles necessary to design ergonomically acceptable phone systems and swinging doors are the same principles needed to effectively design automated computer systems. Software engineers, designers, and requirements analysts will find this a rewarding and useful book. Buy a copy for your favorite employee or relative, or anyone who is occasionally frustrated or baffled with the complexities of life's everyday objects.
