Simulation and presentation of curved surface in virtual reality environment through surface display

Force feedback can be thought as a concept which was motivated by the phenomenon of contact. Efforts were made to describe cross sections in interfaces and methodologies to realize force feedback from differences in the cross sections. Based on this discussion. The concept of surface display was submitted and technical issues for the implementation of the concept were pointed out. A prototype device to demonstrate the concept was created and solutions for technical issues mere suggested. The concept of surface display is an idea to present the surface of a virtual object itself to the user, rather than the sensation of force or tactile caused by the contact with the virtual object. The prototype device consisted of a mechanism to form arbitrary surfaces and sensors to measure the force affected on the surface. The control and calculation methods for this device are also described
