ABSTRACT:
A device provides pointing device functions in a keyboard without requiring a keyboard operator to move his hands from their normal typing positions. Position sensitive elements at the top surfaces of a set of keys are used together to provide a large touch surface to allow accurate pointing. The position sensitive elements detect the position of a pointing object such as a finger on the top surfaces of these keys as an indication of information to be conveyed by the user.
