First Claim
1. A mobile device comprising:
- a display;
a fingerprint sensing circuit; and
a fingerprint movement detection circuit, operatively coupled to the fingerprint sensing circuit and to the display, and operative to determine at least one of;
a direction of movement and a rate of movement, of skin texture being sensed by the fingerprint sensing circuit and to produce pointing output data for the display.

Abstract
A display pointing device (10) includes a fingerprint sensing circuit (18) that optically senses, for example, a portion of a fingerprint or other skin texture, and a fingerprint movement detection circuit (20), operatively coupled to the fingerprint sensing circuit (18), that is operative to determine a direction of movement and a rate of movement of skin texture being sensed by the fingerprint sensing circuit (18) to produce pointing output data (24) for a display (12). The pointing output data (24) may be, for example, data representing a visual indication of a position on a display screen, such as a position of a cursor or of highlighted text, or any other suitable position indication. A method for providing pointing information for display includes sensing a fingerprint, determining a direction of movement and a rate of movement of the fingerprint and producing a pointing output for display based on a determined direction of movement and rate of movement of the sensed fingerprint.
