Abstract: | Parameterized Action Representation (PAR) designed to bridge the gap between
natural language instructions and the virtual agents who are to carry their action for virtual
maintenance process. PAR is therefore constructed based jointly on implemented motion capabilities
of virtual human or agent action for instruction interpretation. Maintenance Task Decomposition
Model and Actions Database (Action-DB) is presented based on the PAR and Intelligent Virtual
Maintenance Training System in Delmia environment in this paper. And a real time execution
architecture controlling 3D animated virtual human or agent is proposed based on PAR model.
Finally, an example is given to verify the simulation process of models and method proposed. And
results show that PAR Action-DB is convenient to simulate the virtual maintenance process. |
