Abstract

An imaging device (100) having an imaging system (102) that optically detects movement of an appendage (104), and a processor (200) that automatically translates the movement of the appendage to alphanumeric symbols (400) or graphical user interface navigation commands. The processor can automatically implement the alphanumeric symbols or navigation commands in an application (208). In addition, the processor can automatically identify a second alphanumeric symbol (502) that has a high statistical probability of following a first alphanumeric symbol (500). The processor also can detect a speed at which the appendage is moved and generate a motion parameter correlating to the detected speed. The processor can process the motion parameter to automatically translate the movement of the appendage. The processor can correlate the motion parameter to a user interface scroll speed.

Claims

1. An imaging device, comprising:

an imaging system that optically detects movement of an appendage; and

a processor that automatically translates the movement of the appendage to alphanumeric symbols or graphical user interface navigation commands, and automatically implements the alphanumeric symbols or navigation commands in an application.

2. The device of claim 1, wherein the processor further detects a speed at which the appendage is moved, and generates a motion parameter correlating to the detected speed at which the appendage is moved.

3. The device of claim 2, wherein the processor processes the motion parameter to automatically translate the movement of the appendage.

4. The device of claim 2, wherein the processor further correlates the motion parameter to a user interface scroll speed.

5. The device of claim 1, wherein the processor automatically identifies a second alphanumeric symbol in response to translating the movement of the appendage to a first of the alphanumeric symbols.

6. The device of claim 5, wherein the second alphanumeric symbol identified by the processor has a high statistical probability of following the first alphanumeric symbol.

7. The device claim 6, wherein the processor changes the second alphanumeric symbol to an alphanumeric symbol that correlates to the additional movement of the appendage that is optically detected by the imaging system

8. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:

optically detecting movement of an appendage;

automatically translating the movement of the appendage to alphanumeric symbols or graphical user interface navigation commands; and

automatically implementing the alphanumeric symbols or navigation commands in an application.

9. The machine readable storage of claim 8, further causing the machine to perform the steps of:

detecting a speed at which the appendage is moved; and

generating a motion parameter correlating to the detected speed at which the appendage is moved.

10. The machine readable storage of claim 9, wherein the step of automatically translating the movement further comprises processing the motion parameter.

11. The machine readable storage of claim 9, wherein the step of automatically translating the movement further comprises correlating the motion parameter to a user interface scroll speed.

12. The machine readable storage of claim 8, further causing the machine to perform the step of:

responsive to translating the movement of the appendage to a first of the alphanumeric symbols, automatically identifying a second alphanumeric symbol.

13. The machine readable storage of claim 8, further causing the machine to perform the step of:

responsive to translating the movement of the appendage to a first of the alphanumeric symbols, automatically identifying a second alphanumeric symbol that has a high statistical probability of following the first alphanumeric symbol.

14. The machine readable storage of claim 13, further causing the machine to perform the step of:

responsive to optically detecting at least one additional movement of the appendage, changing the second alphanumeric symbol to an alphanumeric symbol that correlates to the additional movement.

15. A method for controlling a device having an image capture system, comprising:

optically detecting movement of an appendage;

automatically translating the movement of the appendage to alphanumeric symbols or graphical user interface navigation commands; and

automatically implementing the alphanumeric symbols or navigation commands in an application.

16. The method according to claim 15, further comprising:

detecting a speed at which the appendage is moved; and

generating a motion parameter correlating to the detected speed at which the appendage is moved.

17. The method according to claim 16, wherein the step of automatically translating the movement of the appendage further comprises processing the motion parameter.

18. The method according to claim 16, wherein the step of automatically translating the movement further comprises correlating the motion parameter to a user interface scroll speed.

19. The method according to claim 15, further comprising:

responsive to translating the movement to a first of the alphanumeric symbols, automatically identifying a second alphanumeric symbol.

20. The method according to claim 15, further comprising:

responsive to translating the movement of the appendage to a first of the alphanumeric symbols, automatically identifying a second alphanumeric symbol that has a high statistical probability of following the first alphanumeric symbol.
