Abstract
Methods for determining positions of objects for use in an optical touch system are provided. The optical touch system at least includes a depth image sensor and a touch plane, the depth image sensor having a sensing area covering the touch plane. First, when an object is detected by the depth image sensor, image information is obtained by using the depth image sensor, wherein the image information includes angle information and depth information related to the depth image sensor for the object. Thereafter, it is determined whether a position of the object is located at the inside or the outside of the touch plane according to the angle information and the depth information.
