Mochitsuki

Abstract

We made a system to reproduce the experience of pounding rice cake with pestle ("Mochitsuki") by presenting integrated visual, auditory and haptic sensations. In Mochitsuki, players turn steamed glutinous rice into rice cake by pounding it with pestles. In our system, we focused on three important aspects of Mochitsuki: reaction force/deformation at the moment of pounding, rice cake sticking, and rice cake stretch when lifting pestles. In order to reproduce the change of the feeling from steamed glutinous rice to rice cake, these three elements (Reaction force/deformation, sticking, and stretch) are controlled and presented to experiences.
