We propose a wristband-shaped touch input device. Our system uses the surface of the user’s hand as a touchpad. The wristband device detects a position of user’s fingertip by using infrared photo reflective sensors. The user who wears the sensor can input pointing action by touching across the surface of his/her back of hand. Additionally, haptic sensation on the skin surface of the hand supports the user to control various small computing devices (especially touch screen devices) without any visual assistance.
