1. A method for driving a multi-touch system, the method comprising:
- extracting using a digital processor a touch frequency and at least one angle associated with at least one touch from image information captured by each of at least two cameras;
selecting a touch mode on the basis of sum value of the touch frequencies extracted from the image information captured by the cameras; and
performing a touch function corresponding to the selected touch mode using a user interface.

Abstract
Provided are a multi-touch system and a driving method thereof. The method includes, extracting using a digital processor a touch frequency and at least one angle associated with at least one touch from image information captured by each of at least two cameras, selecting a touch mode on the basis of sum value of the touch frequencies extracted from the image information captured by the cameras, and performing a touch function corresponding to the selected touch mode using a user interface.

5. The method according to claim 4, wherein the touch mode is selected when a sum value of the touch frequency of the at least one touch in the generated image information for the cameras is included within a range of sum values of the frequency of touches that correspond to the touch mode, for between 50 and 100% of the frames in the set of frames.
- 6. The method according to claim 4, wherein the touch function simulates pressing of a mouse left button.
- 7. The method according to claim 4, wherein the touch function simulates pressing of a mouse right button.
- 8. The method according to claim 4, wherein the touch function simulates pressing of a mouse scroll button.
- 9. The method according to claim 4, wherein the touch function performs toggling the state of a virtual keyboard between an off state and an on state.

15. A multi-touch system comprising:
-
a touch recognition unit generating at least two image information; a digital processor calculating a frequency of touch and angles from each image information; a controller selecting a touch mode in response to the sum value of the calculated frequency of the touch from the at least two image information; and a user interface performing a touch function corresponding to the touch mode. - View Dependent Claims (16, 17, 18, 19, 20)
