Abstract

A device, system, and computer-readable medium for an interactive whiteboard including an interface which receives a first control signal from a touch-sensitive display surface and a second control signal from a codec, the first control signal identifying a position on the touch-sensitive display surface, and the second control signal identifying a codec setting of the codec; and a processor which calculates, based on the first control signal and the second control signal, a corresponding position on a display screen of a computing device to the position on the touch-sensitive display surface, and which sends the corresponding position to the computing device.

Claims

1. A calibration logic device comprising:

an interface configured to receive a first control signal from a touch-sensitive display surface and a second control signal from a codec, the first control signal identifying a position on the touch-sensitive display surface, and the second control signal identifying a codec setting of the codec; and

a processor configured to calculate, based on the first control signal and the second control signal, a corresponding position on a display screen of a computing device to the position on the touch-sensitive display surface, and to send the corresponding position to the computing device.

2. The calibration logic device of claim 1, wherein the position on the touch-sensitive display surface identifies a position of an occurred event, the occurred event including at least one of touching the touch-sensitive display surface, double tapping or clicking the touch-sensitive display surface, and performing a dragging motion on the touch-sensitive display surface.

3. The calibration logic device of claim 1, wherein the position on the touch-sensitive display surface is represented by X₁, Y₁ coordinates.

4. The calibration logic device of claim 3, wherein the corresponding position on the display screen of the computing device is represented by X₂, Y₂ coordinates.

5. The calibration logic device of claim 1, wherein the second control signal includes American Standard Code for Information Interchange (ASCII) information.

6. The calibration logic device of claim 1, further comprising:

a calibration profile database configured to store a plurality of calibration image layouts,

wherein the codec setting of the codec is associated with one of the plurality of calibration image layouts.

7. The calibration logic device of claim 6, wherein the corresponding position on the display screen of the computing device is calculated based on the touch-sensitive display surface and at least one of the plurality of calibration image layouts.

8. The calibration logic device of claim 1, wherein the processor determines at least one of a model and manufacturer of the codec and a model and manufacturer of the touch-sensitive display surface.

9. The calibration logic device of claim 1, wherein the codec setting identifies at least one of an image layout, an active or inactive signal, a data sharing setting, and a region source.

10. The calibration logic device of claim 1, wherein the second control signal further identifies a position in the codec setting of a screen image generated on the computing device.

11. A system comprising:

a touch-sensitive display surface;

a codec; and

a calibration logic device configured to,

receive a first control signal from the touch-sensitive display surface and a second control signal from the codec, the first control signal identifying a position on the touch-sensitive display surface, and the second control signal identifying a codec setting of the codec,

calculate, based on the first control signal and the second control signal, a corresponding position on a display screen of a computing device to the position on the touch-sensitive display surface, and

send the corresponding position to the computing device.

12. The system of claim 11, wherein the position on the touch-sensitive display surface identifies a position of an occurred event, the occurred event including at least one of touching the touch-sensitive display surface, double tapping or clicking the touch-sensitive display surface, and performing a dragging motion on the touch-sensitive display surface.

13. The system of claim 11, wherein the position on the touch-sensitive display surface is represented by X₁, Y₁ coordinates.

14. The system of claim 13, wherein the corresponding position on the display screen of the computing device is represented by X₂, Y₂ coordinates.

15. The system of claim 11, wherein the second control signal includes American Standard Code for Information Interchange (ASCII) information.

16. The system of claim 11, wherein the calibration logic device further comprises:

a calibration profile database configured to store a plurality of calibration image layouts,

wherein the codec setting of the codec is associated with one of the plurality of calibration image layouts.

17. The system of claim 16, wherein the corresponding position on the display screen of the computing device is calculated based on the touch-sensitive display surface position and at least one of the plurality of calibration image layouts.

18. The system of claim 11, wherein the calibration logic device determines at least one of a model and manufacturer of the codec and a model and manufacturer of the touch-sensitive display surface.

19. The system of claim 11, wherein the codec setting identifies at least one of an image layout, an active or inactive signal, a data sharing setting, and a region source.

20. A computer-readable storage medium including computer executable instructions, wherein the instructions, when executed by the computer, cause the computer to perform a method comprising:

receiving a first control signal from a touch-sensitive display surface and a second control signal from a codec, the first control signal identifying a position on the touch-sensitive display surface, and the second control signal identifying a codec setting of the codec;

calculating, based on the first control signal and the second control signal, a corresponding position on a display screen of a computing device to the position on the touch-sensitive display surface; and

sending the corresponding position to the computing device.
