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

Abstract

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.

A software model and specification language for non-WIMP user interfaces

“…Finally, the SHADOW system [Morrison 1998;Morrison and Jacob 1998] incorporates its own solver along similar lines, along with features for time management and run-time decimation of link bodies.…”

“…We are developing a more ambitious system based on this approach [Morrison 1998;Morrison and Jacob 1998]. SHADOW uses the same two-part model, combining one-way constraints for its continuous part with state transition diagrams for its discrete part.…”

A toolset supported approach for designing and testing virtual environment interaction techniques

“…Jacob et al have developed another visual hybrid formalism which describes virtual environment interaction (Jacob, 1996;Morrison & Jacob, 1998). Again, because this was designed as a control formalism for a virtual environment user interface management system (UIMS), as part of a design process we consider it to be a mix of abstractions.…”

“…In Section 4.1 we discussed the hybrid notation developed by Jacob et al and presented in Jacob (1996) and Morrison and Jacob (1998) for use in a UIMS. Similarly, the work we present here links a hybrid speci"cation to implementation but in a di!erent way.…”

“…In addition, it handles discrete events as discrete events and it provides a mechanism for communication between the continuous and the discrete sub-system. Our UIDL is described in more detail and with more examples in [28] and [31]; and a related, more powerful system based on it, in [1].…”
