User-interface developments for the nineties

Abstract

The purpose and history of user interfaces are briefly recounted. The language model and the implementation model of the user-computer dialogue are examined. User-centered design is discussed, and approaches to design tools are described. Key developments for the 1990s are considered. These include base technologies, 3-D user interfaces, virtual realities, multimedia and hypermedia, groupware, and intelligent agents, i.e., computer-based assistants or guides.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
