ABSTRACT:
A cursor control device is provided which has good operability and can reflect clearly an operator's natural motion in accordance with a qualified value (conversion coefficient). The cursor control device is constituted of an operation plate 5 with an operation surface 7, an operation pressure detecting detector with a pressure-sensitive sensor 3 arranged on the back surface of the operation plate 5 to detect a touch pressure by a control member, and an arithmetic circuit. The arithmetic circuit performs an arithmetic operation of both the coordinate position and the moving rate of the control member using a detection signal from the operation pressure detection detector, and the movement of a cursor based on a first qualified value and a second qualified value. The first qualified value is determined according to the movement and the moving rate of a coordinate position. The second qualified value is determined according to the touch pressure of the control member.
