TOUCH INTERFACE SYSTEM AND METHOD

摘要

A touch interface system and a method for providing a touch interface by detecting a change in a pixel characteristic in a pixel selected with a sensing terminal. The touch interface system includes the sensing terminal to select a location corresponding to a pixel on a display unit, and a display processing module to change a pixel characteristic of the selected pixel to generate a processed pixel on the display unit. The sensing terminal in response recognizes the pixel with a changed pixel characteristic as the processed pixel, and the display processing module communicates with the sensing terminal to determine the location of the processed pixel. Accordingly, the location of the processed pixel may be received as a user input.
