METHOD FOR DETECTING TRACKS OF TOUCH INPUTS ON TOUCH-SENSITIVE PANEL AND RELATED COMPUTER PROGRAM PRODUCT AND ELECTRONIC APPARATUS USING THE SAME
First Claim
1. A method for detecting tracks of touch inputs on touch-sensitive panel, applied to an electronic apparatus having a touch-sensitive panel, the method comprising:
- during a first period, detecting M touch positions of M touch inputs on the touch-sensitive panel;
during a second period, detecting N touch positions of N touch inputs on the touch-sensitive panel, wherein M and N are positive integers and M is less than or equal to N;
selecting a specific touch input from the M touch inputs, wherein the specific touch input corresponds to a specific touch position of the M touch positions; and
determining a track of the specific touch input on the touch-sensitive panel according to N distances that are between the specific touch position and the N touch positions respectively.
