Abstract
A multi-mode input control device for use with a computer via a graphic user interface (GUI) is disclosed. The input control device may optionally perform functions of a mouse device and a trackball device. The mouse and trackball devices share the same key switch, control unit, interface circuit, and signal channel to the computer, which are included in the mouse device. In the mouse mode, the mouse device is individually moved to perform the input control operation in a conventional manner. For the trackball mode, a first signal connector of the trackball device and a second signal connector of the mouse device are connected to each other so that the trackball device can perform the input control operation via the mouse device.
