Abstract:
This paper introduces a semantic representation for virtual prototyping
in interactive virtual construction applications. The representation
reflects semantic information about dynamic constraints to define
objects’ modification and construction behavior as well as
knowledge structures supporting multimodal interaction utilizing speech
and gesture. It is conveniently defined using XML-based markup for
virtual building parts.
The semantic information is processed during runtime in two ways:
Constraint graphs are mapped to a generalized data-flow network and
scene-graph. Interaction knowledge is accessed and matched during
multimodal
analysis.
