COMBINED FINGERPRINT ACQUISITION AND CONTROL DEVICE
First Claim
1. A system for imaging a fingerprint for input of pointing information for a computer, said system comprising:
- a fingerprint image acquisition scanner for acquiring a fingerprint image of a finger; and
an image processor for extracting from said fingerprint image at least one contact parameter other than any optional authentication status data for said fingerprint image.

Abstract
The present invention combines the functionality of a computer pointing device with a fingerprint authentication system. In the preferred embodiment, by regularly scanning fingerprints acquired from the pointing device touch pad, fingerprint features may be extracted and compared to stored data on authorized users for passive authentication. Furthermore, calculations based upon the acquired fingerprint images and associated features allows the system to determine six degrees of freedom of the finger, allowing the user to control a variety of functions or to manipulate a three-dimensional model or virtual reality system.
