| Greta Engine |
Gesture Engine, an animation system
that synthesizes human gesturing behaviors from augmented
conversation transcripts using a database of highlevel
gesture definitions. An abstract scripting language to
specify hand-arm gestures is introduced that incorporates
knowledge from sign language research, psycholinguistics,
and traditional keyframe animation. A new planning algorithm
instantiates and adjusts gestures according to communicative
context and temporal constraints obtained from
a speech synthesizer. The system animates an MPEG-4
compliant skeleton using Body Animation Parameters. |
