Dilatant fluid based tactile display -Basic concept

Recent years with the spread of tactile interfaces, there are many types of tactile displays. Many types of these conventional devices are displaying the physical information of the environment, such as the object shapes or forces. In other hand recent devices displays not the physics itself but the information of cutaneous sensation. However these latter devices are not multi purposed but very much specialized devices. Each expression of the object requires each different device. Here we propose multi purpose oriented display using a fluid which is deformable and elasticity changeable. With this device we consider the new type of display which has expression of various type of elasticity and the possibility of controllable deformation. In this paper we propose tactile display using dilatant fluid as having dynamic elasticity and deformable material.
