Coherency of Kinesthetic and Visual Sensation in Virtual Reality System

|To realize highly realistic sensation of presence in virtual environment, it is necessary to implement virtual reality system tting human sensory mechanism, which integrates multiple kinds of sensory information, including kinesthetic and visual sensation. To provide coherency between kinesthetic and visual sensation of presence, we have proposed the concept of virtual human. However, this concept has not been realized mainly because of di culty in description of virtual environment. We developed an objectoriented method for describing virtual environment, which is exible, easy to construct the environment, and e cient for image generation, using the class of C++ language. We con gured a system using human motion measurement and visual information display, and implemented the virtual environment description method on the system. Using this system, we made an experiment on the in uence caused by the condition whether the coherency between kinesthetic and visual sensation of presence is satis ed. The result shows that there is signi cant di erence between the case which the above condition is satis ed and that does not.
