THREE-DIMENSIONAL OPERATION CONTROL METHOD AND DEVICE FOR TOUCHSCREEN, AND MOBILE TERMINAL THEREOF

Disclosed are a three-dimensional operation control method and device for a touchscreen, and a mobile terminal thereof. The method comprises the following steps: collecting capacitance values of at least two collection points in a motion track formed by a finger or a conductor in a touchscreen sensing space; according to the capacitance values of the collection points, respectively performing calculation to obtain the coordinates of the collection points on the X axis, the Y axis and the Z axis, thereby obtaining the three-dimensional coordinates of the collection points; and according to the three-dimensional coordinates of the at least two collection points, determining the motion track and executing corresponding operations. By means of the above-mentioned manner, the present invention can achieve the identification of three-dimensional gestures and abundant mobile terminal operations.
