Abstract
THESEUS++ is an object-oriented high level user interface toolkit especially designed to ease development of application-specific interaction with 2,5 D graphics. THESEUS++ enforces the separation between the application and user interface in a flexible way. These parts of the dialogue, that don't require application-specific knowledge, can be described on a high level of abstraction, while semantic feedback on a low level is possible for those dialogue cycles needing application knowledge. This is accomplished by the following features: * A description model for the separate specification of interaction components like prompt, feedback, and semantics on each level of the interaction hierarchy * Dynamic composition mechanisms both for the definition of complex interactions (dialogue hierarchy) and for complex graphical objects (picture hierarchy). * Support for constraint-based direct manipulation of application-defined graphics including continuous interactions like dragging and stret ching * Mechanisms to support extensibility by new classes of domain-specific interaction techniques and graphical objects. THESEUS++ has been implemented in object-oriented C++ on top of X Window System and OSF/Motif.
