Interactivity is the catchword for a wide range of innovative solutions that concept designers and engineers are developing in every area of technology and culture. For the authors interaction is more than a technological or aesthetic concept, it is a new means to ally humans and technology in a dynamic and reciprocal form of “living in technology”. This publication gathers together scientists and contributors from diverse fields of activity, providing a fascinating, up-to-date survey of the technological and conceptual equipment of experts engaged in aesthetic disciplines and product design. The editor, Professor Gerhard M. Buurman, is Head of Interactiondesign at the University of Art, Media and Design (HGKZ) in Zurich.
