ABSTRACT:
The present invention is described as a computer data entry apparatus having a keyboard comprised of a keypad assembly and equipped with one or multiple motion sensing devices, and having a motion monitoring visual aid display. The motion sensing device is included to the apparatus to detect and sense the motion of operator finger locations before or after keys are actuated for data entry. A map with a keypad layout and sensed finger locations is interactively generated and displayed on a window of the computer display screen to provide the data entry visual aid. The combined function of motion sensing and visual aid displaying advantageously constitutes an easy operation computer data entry apparatus or system.
