Accomplished authors, Preece, Rogers and Sharp, have written a key new textbook on this core subject area. Interaction Design deals with a broad scope of issues, topics and paradigms that has traditionally been the scope of Human--Computer Interaction (HCI) and Interaction Design (ID). The book covers psychological and social aspects of users, interaction styles, user requirements, design approaches, usability and evaluation, traditional and future interface paradigms and the role of theory in informing design. The topics will be grounded in the design process and the aim is to present relevant issues in an integrated and coherent way, rather than assembling a collection of chapters on individual HCI topics. KEY FEATURES: aeo This truly integrated approach to HCI provides students with background information from psychology, sociology, anthropology, information systems and computer science aeo Provides principles and skills for designing any technology through the use of many interesting and state of the art examples aeo The author supported, highly interactive Web Site provides resources that allow students to collaborate on experiments, participate in design competitions, collaborate on design, find resources and communicate with others aeo The accompanying Web Site also features examples, step--by--step exercises and templates for questionnaires CONTENTS: Preface 1.
