Abstract
A dual mode input device, e.g. an optical mouse, is capable of performing data input function by moving the input device. Alternatively, the dual mode input device can also be an optical trackball. By turning the dual mode input device upside down, a trackball can be mounted to or exposed from the bottom surface to perform data input function by manipulating the trackball so that no movement of the input device is required.
