Abstract

A universal touch input driver includes a device driver interface through which touch data is obtained from a device driver. Also included is a computation module that processes the touch data and converts it into a standardized format. Also included is an application interface through which the standardized touch data is transferred to a touch input application.

Claims

1. A universal touch input driver comprising:

a device driver interface through which touch data is obtained from a device driver;

a computation module that processes the touch data and converts it into a standardized format; and

an application interface through which the standardized touch data is transferred to a touch input application.

2. The universal touch input driver of claim 1, wherein the standardized touch data is formatted so as to include, for a record of a touch instance, an x-coordinate, a y-coordinate, a change in x, a change in y, a width, a height, and an acceleration.

3. The universal touch input driver of claim 1, wherein the standardized touch data is formatted in accordance with user datagram protocol.

4. The universal touch input driver of claim 1, wherein said transfer of standardized touch data is a transmission to a network port.

5. The universal touch input driver of claim 1, wherein the standardized touch data is formatted in extensible markup language.

6. The universal touch input driver of claim 1, wherein said transfer of standardized touch data is a transmission to a TCP or UDP port.

7. The universal touch input driver of claim 1, wherein the standardized touch data is formatted so as to be consistent with both user datagram protocol and extensible markup language.

8. The universal touch input driver of claim 1, further comprising:

a storage module that stores the touch data from the device driver.

9. The universal touch input driver of claim 8, wherein the universal touch input driver incorporates the stored touch data along with additional touch data not stored in the storage module into the standardized touch data.

10. A method of providing standardized data to a touch input application, the method comprising:

obtaining touch data from a device driver;

converting the touch data to touch data having a standardized format;

transferring the touch data having the standardized format to the touch input application.

11. The method of claim 10, further comprising:

storing other touch data.

12. The method of claim 11, further comprising:

incorporating the touch data and the other touch data into the touch data having the standardized format.

13. The method of claim 10, wherein converting the touch data to touch data having a standardized format comprises defaulting data.

14. The method of claim 13, wherein defaulting data comprises defaulting a height and a width.

15. The method of claim 10, wherein converting the touch data to touch data having a standardized format comprises generating a change in x value and a change in y value.

16. The method of claim 10, wherein converting the touch data to touch data having a standardized format comprises generating touch data in multiple formats.

17. A universal touch input driver comprising:

an interface through which is received a first set of data from a touch input device and a second set of data from another device;

a computational module that process the first and the second sets of data and converts them into a combined set of data having a standardized format; and

another interface through which the combined set of standardized data is transferred to an application.

18. The universal touch input driver of claim 17, wherein the another device is a non-touch device.

19. The universal touch input driver of claim 17, wherein the another device is a multitouch input device.

20. The universal touch input driver of claim 18, wherein the another device has a different shape, orientation, or size than the touch input device.

21. The universal touch input driver of claim 17, wherein the another device is an image recognition device.

22. The universal touch input driver of claim 17, wherein the another device is a fiducial marker recognition device.
