Abstract
Some embodiments include an input device comprising a processor and a key frame having a plurality of keys disposed therein and a motion sensor controlled by the processor and disposed below the key frame. The plurality of keys includes a controller key and one or more input keys, where the motion sensor generates a signal corresponding to a movement of an object along the surface of the one or more input keys when the controller key is activated, where the signal can be used to control a cursor on a display. Each of the one or more input keys generates an input function when activated and can include one or more of an alphanumeric input, arrow key input, or function key input. In some cases, the controller key can be one or more of a shift key, control key, windows key, command key, alt key, dedicated controller key, or user-assigned key.
