Jensen identifies the roots of interaction and interactivity in media studies, literature studies and computer science, and presents definitions of interaction as something going on among agents and agents and objects, and of interactivity as a property of media supporting interaction.
Virtual Interaction: Interaction in Virtual Inhabited 3D Worlds answers the basic research questions involved in the development of new, user-friendly interfaces. Containing the edited research papers resulting from an ambitious, cross-disciplinary research project, this volume examines the core activity of interfaces: interaction. (Two other volumes look at Space Construction, and Staging.) This book takes the reader all the way from general theories and conceptualisations of interaction aspects of virtual inhabited 3D worlds, through theories of and methods for the design of autonomous agents, ending in specific design methodology considerations and suggestions for management in the multimedia industry.
