In this paper we describe ongoing research that aims at the development
of a generic demonstration platform for virtual prototype modeling by
utilizing multimodal ­ speech and gesture ­ interactions in Virtual
Reality. Particularly, we concentrate on two aspects. First, a knowledge-
based approach for assembling CAD-based parts in VR is introduced.
This includes a system to generate meta-information from geometric models
as well as accompanying task-level algorithms for virtual assembly.
Second, a framework for modeling multimodal interaction using gesture
and speech is presented that facilitates its generic adaptation to
scene-graph-based applications. The chosen decomposition of the required
core modules is exemplified by an example of a typical object rotation
