Passive force display method to actualize virtual clay

The purpose of this study is to construct a force display method for virtual clay with a passive force display. It is difficult for passive systems to send feedback forces against soft objects such as clay because the systems cannot actively send feedback elasticity. However, it is essential for virtual worlds to send feedback forces from virtual clay because there are many soft objects like clay in the real world. Passive force display will enable force feedback from clay by way of expressing resistance against an operator's force. Therefore, if the force feedback of virtual clay is actualized in the same way as active force display with a motor, then it will be possible to realize many applications and easily control the systems compared with active systems.
