The field of human-computer interaction (HCI) has attracted researchers with interests as diverse as formal mathematics, ethnography, cognitive psychology, and conversation analysis. Each approach has different assumptions and perspectives on the practical problem of designing more effective systems. Perspectives on HCI: Diverse Approaches contains 10 tutorial chapters, each written to illustrate a particular approach to HCI. The authors are all international authorities in their particular fields. The book will be of interest to researchersand students in computer science, management science, psychology, human factors, ergonomics, and sociology who want to know how other disciplines approach the practical problem of making computers into more effective tools for people to use.
