Abstract:
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 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:
