Abstract:
A method for detecting touch-point coordinates includes: scanning a plurality of signal points in sequence to generate a plurality of original data including a plurality of original touch point data; performing a grouping algorithm for the original touch point data to group the original touch point data into a plurality of group sets; and calculating a barycentric coordinate of each of the group sets and outputting the barycentric coordinate as a touch-point coordinate of each of the group sets.
