Abstract
A sensor device is placed either underneath a key cap of a key on a keyboard or in between two keys on a keyboard so that cursor movement may be carried out from the keyboard itself. If the sensor device is placed underneath a key cap, then the key cap is a manual cursor controller. If, on the other hand, the sensor device is placed in between two keys, a joystick is used as a manual cursor controller.
