Patent ID: 8405625

Claim:
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 the specific touch position corresponds to a specific identification; and determining a track of the specific touch input on the touch-sensitive panel according to a plurality of distances that are between the specific touch position and the N touch positions respectively; wherein the step of determining the track of the specific touch input comprises: comparing the distances so as to determine a nearest touch position of the N touch positions that is closest to the specific touch position; setting the nearest touch position to correspond to the specific identification as well; and determining that the specific touch input is moved from the specific touch position to the nearest touch position on the touch-sensitive panel according to the specific identification.
