Abstract
In the past, contact imaging devices were large and costly. It has been proposed that for contact imaging device adoption for the personal computing market, cost and size must be reduced. In an attempt to address these concerns, a biometric pointing device such as a mouse is presented incorporating therein a contact imager. The contact imager fits within a small enclosure. Further, data transmission means within the mouse provides a signal to a single port on a computer indicative of the output data from both the contact imaging means and the pointing device.
