Development of virtual model creation system by real-time force feedback interactive technology

The haptic-based sensing technology (HST) has the potential to be a powerful tool in Human-Computer Interaction (HCI). When developing a new product, the trend is to compress product development cycles and reduce costs. Virtual modeling, sometimes referred as digital prototyping, is widely used in industry for simulating the visual appearance and functionalities. Unfortunately, conventional virtual modeling techniques are hard to simulate the physical properties of a real product in user-to-product interactions. Force feedback, also called sensible feeling, is best envisaged as an evolution of virtual modeling. Thus, a novel haptic rendering technology that enables users to perceive tactile feedback from virtual 3-dimensional models is studied. We mainly carried out some innovative studies on the real-time force feedback in HCI by using sensing device based on the virtual model creation system (VMCS). With this in-depth research work, a virtual mechanics simulation model of the feedback force is proposed to solve the real-time force feedback simulation problem of haptic-based virtual model creation method. Finally, VMCS with real-time force feedback interactive technology is completed by using sensing technologies of haptic sensor devices. All these research works provide theories for the further application of virtual model creation method and HST in related industries.
