A gesture based user interface prototyping system

Abstract

GID, for Gestural Interface Designer, is an experimental system for prototyping gesture-based user interfaces. GID structures an interface as a collection of "controls": objects that maintain an image on the display and respond to input from pointing and gesture-sensing devices. GID includes an editor for arranging controls on the screen and saving screen layouts to a file. Once an interface is created, GID provides mechanisms for routing input to the appropriate destination objects even when input arrives in parallel from several devices. GID also provides low level feature extraction and gesture representation primitives to assist in parsing gestures.
