Pointing and fingerprint identifier mechanism for a computer system

摘要

A computer system controller in the form of a pointing and fingerprint identifier mechanism provides both a pointing mode and a fingerprint identification mode. In the pointing mode, the mechanism serves as a pointing device for cursor movement control. In the fingerprint identification mode, the mechanism serves as a fingerprint identification device to prevent unauthorized use. These modes are generated and controlled by device code executed by control logic within the mechanism. The device code thus integrates pointing functions and fingerprint identification functions in a single device. The need for a distinct fingerprint scanner separate from a pointing device in a computer system is thereby eliminated.
