The optical sensors are arranged around a touch plane and are spaced from each other. The two adjacent optical sensors located at one side of the touch plane are defined as one set of an optical sensing module, such that the optical sensors are paired to form multiple sets of the optical sensing modules. The processing unit generates a plurality of touch coordinates data corresponding to the plurality sets of the optical sensing modules according to the optical touch data, and determines whether the touch coordinates data corresponding to each set of the optical sensing modules is in at least one touch-excluded area corresponding to each set of the optical sensing modules, and respectively excludes the touch coordinates data in the touch-excluded area.

Abstract: A method of detecting a touch position and a touch apparatus thereof are provided. At least three intervally distributed light sensing devices are provided to obtain a plurality of touch information. Based on peak values of the touch information, a total number of touched points is determined. When the total number is larger than 1, touched points on a touch surface are calculated. Touched points being examined corresponding to one of the peak values of a first touch information are obtained. According to distance values related to the touched points being examined, a first and a second to-be-examined touched point are selected. Whether the first and the second to-be-examined touched points are simultaneously corresponding to any one of the peak values of each touch information is determined. If the determination is positive, then a touch position is determined from the first and the second to-be-examined touched points.
