Abstract
The present invention discloses a method for determining touch points on a touch panel and a system thereof. The method includes the following steps: sampling, calculating a difference, comparing the difference, sampling a determinative area, and calculating a barycenter. The barycenter position from the said steps is a touch point position. The present invention can overcome the problem of the ghost point in traditional touch panels and also be applicable for touch panels of various types.
