We built an entertainment VR system that provides the experience of Mochitsuki. This system reproduces the unique feel when pounding rice cake with a pestle. We chose an approach that breaks down the haptic experience into multiple elements and assigns devices to each element, either a physical device or an electronically-controllable device. With this configuration, direct interactions between the user and the system are all performed by physical devices to ensure the quality of experience, while the parameters affecting the experience can be controlled by electronic devices and mechanisms. In this thesis, we report the findings obtained up to the present time.
