Garnet: comprehensive support for graphical, highly interactive user interfaces

The Garnet research project, which is creating a set of tools to aid the design and implementation of highly interactive, graphical, direct-manipulation user interfaces, is discussed. Garnet also helps designers rapidly develop prototypes for different interfaces and explore various user-interface metaphors during early product design. It emphasizes easy specification of object behavior, often by demonstration and without programming. Garnet contains a number of different components grouped into two layers. The Garnet Toolkit (the lower layer) supplies the object-oriented graphics system and constraints, a set of techniques for specifying the objects´ interactive behavior in response to the input devices, and a collection of interaction techniques. On top of the Garnet Toolkit layer are a number of tools to make creating user interfaces easier. The components of both layers are described.<>
