A specification paradigm for design and implementation of non-WIMP user interfaces

The SHADOW System is a user interface management system designed to address the specific needs of non-WIMP interfaces such as virtual environments, gesture recognizers and other interactions that involve highly parallel, continuous interaction. The proposed UIMS consists of a graphical specification language based on augmented transition networks and data flow graphs, a code translation system which supports dynamic constraint binding, modular design and code reuse, and a run time engine designed to optimize the use of processing resources within a time sensitive environment while preserving a layer of platform independence for the application.
