A basic device combining a tactile display function and a touch position/force direction sensing function is proposed. The first trial device consists of two major components, a tactile graphic display and a 6-axis force/torque sensor. The proposed device is substituted for the mouse functions of clicking and scrolling, and it provides fundamental GUI operations. From the knowledge acquired from the first trial device, we developed new tactile input/output device which focused on enlargement of tactile presentation area, improvement in position detection accuracy, and improvement in ease of movement. In this paper, we explain the structure of the device, and development of a 3-axis force sensor. Since the new position detection principle accompanies the change of the device mechanism, we also illustrate the position detection method.
