Claim Text:
1. A method for touch identification, comprising: performing an axial scanning on a touch screen, and when a touch region is detected, recording scanning axes with scanning rays shielded; corresponding to the detected touch region, according to axial directions, obtaining sets of intersections of the scanning axes with scanning rays shielded; calculating a confidence level for each of the intersection in each set of intersections; and performing a coordinate fusion to all the sets of intersections which correspond to the touch region based on the confidence levels to obtain positions of the touch region, wherein a portion of the touch region where a scanning axis locates is a parallelogram region, a base of the parallelogram region is an axial position of the touch region, and an angle between the base and a lateral side of the parallelogram region is a deflection angle of the scanning rays with scanning rays shielded.
