A Uniform Specification of Mixed Reality Interface Components

This is a short presentation of a uniform approach for specifying mixed reality user interfaces, including 3D interaction techniques and 3D widgets. Our main goal is to facilitate the process of reusing previous work, so more complex applications can be built and documented in a formal and uniform way. We describe here the conceptual model of user interface components, which allows us to generalize user interface components and to port them to different hardware settings and application contexts. An XML-based specification language implements the conceptual model and allows for automatic processing and tool support.
