Abstract :
The paper presents a reliable method of extracting finger 2D gestures on an optical touch panel. All the testing data is captured from an optical AMLCD under the normal office lighting. The experimental results show that the method is efficient to correctly extract one or more-finger gestures from the shadow of finger(s) on the AMLCD. Development of such a method contributes to simplification of hardware requirements for reliable detection technique
