Abstract

The present invention relates to a novel pointing device for use with a computer system. The pointing device can be in the form of a mouse, trackball or any other type of apparatus that can be employed by the user of the computer system to displace a cursor on the screen. The novel pointing device features a finger print identification system that enables the computer system to recognize the identity of the individual whose finger is being scanned. The advantage of providing the pointing device with a finger print recognition capability is the ease and simplicity with which user identification can be effected. In another aspect of the invention, a pointing device is provided that is capable of optically detecting and tracking significant papillary features the user's finger. Thus, the movement of the user's finger can be mapped to the displacement of the cursor on the screen. The main advantage of this approach is to enable a much higher resolution in detecting the finger position by comparison to traditional methods.

Claims (14)

1. A pointing device for a computer system, said pointing device comprising:
- a finger scanning surface for through which an image of a finger can be transmitted;
- means responsive to a light excitation communicated through said finger scanning surface to generate an output signal representative of an image of at least a portion of a finger.
2. A pointing device as defined in claim 1, wherein said means responsive to light excitation includes a camera optically coupled to said finger scanning surface.
3. A pointing device as defined in claim 2, wherein said camera issues an analog signal representative of the papillary lines of the finger.
4. A pointing device as defined in claim 3, further comprising a signal processing device coupled to said camera and receiving said analog signal for generating an array of bytes, each byte representing at least one image pixel.
5. A pointing device as defined in claim 2, comprising a focusing lens between said camera and said finger-scanning surface.
6. A pointing device for a computer system, said pointing device comprising:
- a finger scanning surface;
- processing means responsive to an image of at least a selected portion of a finger transmitted through said finger scanning surface to generate an output signal mapping a position of the selected portion of the finger relative the finger scanning surface.
7. A pointing device for a computer system as defined in claim 6, wherein said finger scanning surface has an area substantially exceeding an area of a tip of a finger, thereby permitting the tip of the finger to move over said finger scanning surface.
8. A pointing device for a computer system as defined in claim 7, wherein the area of said finger scanning surface is of a size selected to allow the tip of the finger to be displaced over said finger scanning surface in two orthogonal directions.
9. A pointing device for a computer system as defined in claim 6, wherein said output signal constitutes an input suitable for use in a computer system to displace a cursor on computer screen.
10. A pointing device as defined in claim 6, wherein said processing means is capable of detecting and tracking the selected portion of a finger to continuously generate said output signal mapping the position of the selected portion of the finger relative the finger scanning surface.
11. A pointing device as defined in claim 10, wherein said processing means includes means responsive to a light excitation communicated through said finger scanning surface to generate an output signal representative of an image of at least a portion of a finger.
12. A pointing device as defined in claim 11, wherein said means responsive to light excitation includes a camera optically coupled to said finger scanning surface.
13. A pointing device as defined in claim 12, wherein said camera issues an analog signal representative of the papillary lines of the finger.
14. A pointing device as defined in claim 13, further comprising a signal processing device coupled to said camera and receiving said analog signal for generating an array of bytes, each byte representing at least one image pixel.
