Abstract

A basic device combining a tactile display function and a touch position sensing function is proposed. The trial device consists of two major components, a tactile graphic display and a six–axis force/torque sensor. The force sensor measures six dynamic values generated by touch action on the display surface and a PC estimates the touch position based on the data. Since the defects of the first trial production are the weakness of the touch surface, an assembly error, and the measurement error of six–axis force/torque sensor, they are solved in the second trial production. The effect of a contact force on the estimated position are examined respectively by a vertical component and a horizontal component. It is shown from the above experimental results that the second trial production is practically sufficient estimated position accuracy.
