In this research, we have measured the grasping touch discrimination by using devices developed by our research group. The device can be varied the hardness of the display by the pressure adjuster of liquid in the device. Subjects have adjusted the hardness of a device to be the same as another referenced device. In this paper, we describe the discrimination of grasping touch action obtained from pressure difference between the referenced device and the adjusted device.
