In this paper, a collaborative product development and prototyping framework is presented by using web-based distributed haptic interfaces along with network flow analysis. Techniques of Collaborative Virtual Environment (CVE) are presented for industrial product development and virtual prototyping. Network control problems such as network traffic and network delay in communication have greatly limited collaborative virtual environment applications. A hybrid network architecture is proposed to balance the computational burden of haptic rendering and deformable object simulation. Adaptive artificial time compensation is used to reduce the time discrepancy between the server and the client. Interpolation and extrapolation approaches are used to synchronize graphic and haptic data transmitted over the network. The presnted techniques can be used for collaborative product development, virtual assembly, remote product simulation and other collaborative virtual environments.
