Recently, various controllers are developed. However, the operation of controller is very difficult for elderly persons. Therefore, the operation that uses the gesture like the hand gesture that can be operated intuitively and easily is researched. Three-dimensional coordinates of the hand are necessary to operate it by the hand gesture. The triangulation is a general method of the three-dimensional coordinates metrology. However each sensor should take the distance enough. Therefore the downsizing of the device is difficult. we suggest three dimension coordinates metrology using camera and ultrasonic sensor. The device can be miniaturized by using the camera and the ultrasonic sensor.
