Virtual prototyping system based on haptic interactive sensors

This paper presents a Virtual Prototyping System (VPS), which can be used in virtual environments generated with the help of computer to simulate the process of real product model that the modelers sculpt product profile. With this system, designers can use the combination of haptic technologies and virtual prototyping method to increase real sense of Human Computer Interaction (HCI) during different steps of design process. The operation of cutting, pasting, and compensating is accomplished by a haptic sensor device, PHANToM Desktop. The virtual mechanics simulation model of the feedback force is proposed to solve the real-time force feedback simulation problem of haptic-based virtual prototyping method. Furthermore, a novel haptic rendering technology that enables users to perceive tactile feedback from virtual 3-dimensional models is studied. Finally, VPS with real-time force feedback interactive technology is completed by using sensing technologies of haptic sensor devices. The study reported in the article adopted an actual case to examine these sensory responses to virtual model that may deeply influence user judgment and decision.
