ABSTRACT:
A pointing device according to the present invention includes a trackball embedded in the case of a computer display. The trackball is placed adjacent to the display and the select buttons for the trackball are located on the backside of the display case behind the trackball. The user guides the trackball with his thumb and pushes the select buttons on the backside of the case with his index and middle fingers, allowing the user to operate the pointing device with only one hand. Alternatively, the trackball is embedded in the corner of the keyboard of a desktop system, with the select buttons on the opposite side of the keyboard behind the trackball. With the keyboard standing on legs, the user's fingers can reach the two select buttons opposite the trackball to operating the pointing device.
