A unique resource covering a full spectrum of issues around human–computer interaction Written by experts from around the globe, this landmark two–volume set introduces emerging technologies for human–computer interaction in contexts such as motion capture, embodied conversational agents, human–robot interaction, corneal imaging and more. While following the traditions of the past, it also points to key technologies and challenges of the future. Volume I begins with design issues (criticality, semiotics, and standards) and the process of design (agile, ethnographic, and user modeling), and moves from factors of evaluation (stress, immersion, and experience) to methods of evaluation (usability testing). It ends with the user from input to output (Fitts’ Law, motion capture, and gaze). Volume II of opens with the interface (multi–surface, visual query, and natural language) and the interactions (embodied agents, mobile media, and robots) that take place there. The remainder of the work deals with accessibility and special needs of user groups, the social aspects of users and communities, and finally a number of specific applications (motor vehicle, advertising, and healthcare). Contributions from authors from research and academic centers around the world (Australia, Brazil, China, Denmark, Egypt, Finland, India, Ireland, Italy, Japan, Korea, Portugal, United Kingdom, and United States) Includes guidance, standards, principles, and case studies for researchers and practitioners in human–computer interaction and design of new technologies Features numerous illustrations, screen shots, and diagrams that bring the text to life The Wiley Handbook of Human Computer Interaction is intended for practitioners and researchers in human–computer interaction (including designers of new products, evaluators and testers, and teachers). It is also ideal for graduate level courses in human–computer interaction.
