Abstract
An object positioning method for touch panel is disclosed. The method includes steps as follows: obtaining a motion estimation vector according to the operational analysis of a positioning coordinate and a sensing coordinate, and determining whether the length of the motion estimation vector is smaller than a predetermined distance or not, if the length of the motion estimation vector is smaller than the predetermined distance, outputting the positioning coordinate; on the contrary, if the length of the motion estimation vector is larger than the predetermined distance, updating the value of the positioning coordinate and outputting the positioning coordinate updated.
