Abstract

Implementations and techniques for differentiating inputs of a display device are generally disclosed.

Claims

1. A method for differentiating inputs of a display device, the method comprising:

receiving an indication of a first distortion of an electric field of the display device, the first distortion having a first pattern;

associating the first pattern with a first input;

receiving an indication of a second distortion of the electric field of the display device, the second distortion having a second pattern;

determining if the first pattern and the second pattern are substantially similar;

associating the second pattern with the first input if it is determined that the first pattern and the second pattern are substantially similar; and

associating the second pattern with a second input if it is determined that the first pattern and the second pattern are not substantially similar.

2. The method of claim 1, wherein the display device comprises a touch screen type display device.

3. The method of claim 2, wherein the touch screen type display device comprises a capacitive touch technology type display device.

4. The method of claim 1, wherein the first and the second distortions comprise a first distortion and a second distortion caused by a conductive material.

5. The method of claim 4, wherein the conductive material comprises a stylus.

6. The method of claim 5, wherein the stylus comprises a stylus configured to provide one or more conductive patterns.

7. The method of claim 1, wherein the first input comprises an input associated with a first user.

8. The method of claim 1, wherein the second input comprises an input associated with a second user.

9. The method of claim 1, wherein the first input comprises an input associated with a first stylus type.

10. The method of claim 1, wherein the second input comprises an input associated with a second stylus type.

11. The method of claim 1, wherein determining if the first pattern and the second pattern are substantially similar further comprises classifying the first pattern and the second pattern among two or more predetermined patterns, wherein associating the first pattern with a first input is based at least in part on one of the two or more predetermined patterns, and wherein associating the second pattern with the second input is based at least in part on one of the two or more predetermined patterns.

12. The method of claim 11, further comprising assigning a dedicated action to the first input and/or the second input based at least in part on the classification of the first pattern and the second pattern among the two or more predetermined patterns.

13. An article comprising:

a signal bearing medium comprising machine-readable instructions stored thereon, which, if executed by one or more processors, operatively enable a computing device to;

receive an indication of a first distortion of an electric field of a display device, the first distortion having a first pattern;

associate the first pattern with a first input;

receive an indication of a second distortion of the electric field of the display device, the second distortion having second pattern;

determine if the first pattern and the second pattern are substantially similar;

associate the second pattern with the first input if it is determined that the first pattern and the second pattern are substantially similar; and

associate the second pattern with a second input if it is determined that the first pattern and the second pattern are not substantially similar.

14. The article of claim 13, wherein the display device comprises a touch screen type display device.

15. The article of claim 14, wherein the touch screen type display device comprises a capacitive touch technology type display device.

16. The article of claim 13, wherein the first and second distortions comprise a first distortion and a second distortion caused by a conductive material.

17. The article of claim 16, wherein the conductive material comprises a stylus.

18. The article of claim 17, wherein the stylus comprises a stylus configured to provide one or more conductive patterns.

19. An apparatus comprising:

a display device;

an input sensitive screen included in the display device;

conductive material included in the display device, the conductive material providing an electric field for the input sensitive screen;

a processor coupled to the display device; and

a signal bearing medium comprising machine-readable instructions stored thereon, which, if executed by the processor, operatively enable a computing device to;

receive an indication of a first distortion of the electric field of the display device, the first distortion having a first pattern;

associate the first pattern with a first input;

receive an indication of a second distortion of the electric field of the display device, the second distortion having second pattern;

determine if the first pattern and the second pattern are substantially similar;

associate the second pattern with the first input if it is determined that the first pattern and the second pattern are substantially similar; and

associate the second pattern with a second input if it is determined that the first pattern and the second pattern are not substantially similar.

20. The apparatus of claim 19, wherein the display device comprises a touch screen type display device.

21. The apparatus of claim 19, wherein the first and second distortions comprise a first distortion and a second distortion caused by a conductive material.

22. The apparatus of claim 21, wherein the conductive material comprises a stylus.

23. The apparatus of claim 22, wherein the stylus comprises a stylus configured to provide one or more conductive patterns.

24. The apparatus of claim 19, wherein the first input comprises an input associated with a first user.

25. The apparatus of claim 19, wherein the second input comprises an input associated with a second user.
