| 20110096028 | ELECTRONIC DEVICE WITH INFRARED TOUCH PANEL AND TOUCH INPUT METHOD THEREOF - A touch input method includes steps: controlling one of the infrared emitters to turn on and send an infrared signal to the infrared receivers in sequence, thus forming a number of first infrared lines. Detecting whether an infrared receiver does not receive the infrared signal. Determining if the first infrared line is blocked by an object, thus determining a first blocked infrared line. Controlling the other infrared emitter to turn on and send the infrared signal to the infrared receivers, thus forming a number of second infrared lines. Determining if the second infrared line is blocked by the object, thus determining a second blocked infrared line. Determining touch position according to the first and the second blocked infrared lines, executing the function of a GUI element corresponds to the touch position. The disclosure also provides an electronic device with an infrared touch panel. | 04-28-2011 |
