Haptic canvas

Abstract

Some kinds of substances naturally attract people to touch them. The slurry made from water and starch is one of the haptically fascinating substances, and presents the amusing but mysterious sensation like playing in the mud when you were in childhood. The mysterious haptic sensation comes from the property of the fluid, "dilatancy", which is the change in the state from liquid-like to solid-like according to the external force. The purpose of this study is to establish the new haptic interaction by presenting both direct touch and mechanically variable haptic sensations with the slurry made from water and starch-i.e., "dilatant fluid".
