Simulation of Haptic Force Feedback Interaction Using Virtual Model

Due to the massive calculations of force feedback, and the difficulty in haptic scenes and graphic scenes refreshing, the real-time force feedback interactive technology in virtual model is studied. Based on the research of force feedback simulation model, a mechanical simulation model using material scrapers rate is presented. This model can calculate the scraping of force feedback according t...

Haptic Feedback for Virtual Reality

Haptic feedback is a crucial sensorial modality in virtual reality interactions. Haptics means both force feedback (simulating object hardness, weight, and inertia) and tactile feedback (simulating surface contact geometry, smoothness, slippage, and temperature). Providing such sensorial data requires desk-top or portable special-purpose hardware called haptic interfaces. Modeling physical inte...

Assembly Simulation on Collaborative Haptic Virtual Environments

Currently, Virtual Environments (VEs) are used within engineering industry: physical prototypes or mock-ups are replaced by virtual prototypes. Increasingly, these VEs also allow designers and engineers to carry out assembly/disassembly processes and assembly sequences before any physical prototype is built. Moreover, different designers or engineers, which may be situated in the same or in geo...
