A virtual environment for collaborative assembly

To allow geographical dispersed engineers to perform an assembly task together, a virtual environment for collaborative assembly (VECA) has been developed to build a typical collaborative virtual assembly system. This presents the key parts of VECA, such as system architecture, HLA-based (high level architecture) communication and collaboration, motion guidance based on collision detection and assembly constraints recognition, data translation from CAD to virtual environment, reference resolution in multimodal interaction.
