A coordinate input device is provided to contribute to improvements in a mechanical mouse, opto-mechanical mouse and the like which are used to control cursor movements in the visual display unit of a computer system. The device comprises a position sensor and a pressure sensor. The position sensor detects a two-dimensional position of the device, which is moved on a flat surface or the like by a person, so as to produce two-dimensional coordinates. The pressure sensor detects a pressing force applied to the device by the person. Hence, the two-dimensional coordinates and the pressing force detected are used as parameters which control a cursor or a graphic image displayed on the screen of the visual display unit. The pressure sensor comprises an air-pressure sensor which detects a change of air pressure caused by the pressing force applied to the device. In addition, the pressure sensor can be replaced by a grip sensor which detects a gripping force applied to the device by the person.
