Hailed on first publication as a compendium of foundational principles and cutting-edge research, The Human-Computer Interaction Handbook has become the gold standard reference in this field. While human-computer interaction may have emerged from within computing, significant contributions have come from a variety of fields including industrial engineering, psychology, education, and graphic design. No where is this more apparent then when designing solutions for users as diverse as children, older adults, and individuals with physical, cognitive, visual, or hearing impairments. Derived from select chapters in The Human-Computer Interaction Handbook, this volume emphasizes design for these groups and also discusses HCI in the context of specific domains including healthcare, games, and the aerospace industry.
