The touch control method according to claim 16, wherein, in the step 104, when the direction of the touch action is a direction of moving from left to right, a touch instruction for turning pages backward is generated; When the direction of the touch action is from the right to the left direction, a touch command for turning the page forward is generated; when the touch action is clicked, a confirmation command is generated.

The touch control method according to claim 15, wherein in the step 105, the motion track of the touch action is determined and acquired according to a preset threshold, and the motion track includes but is not limited to multiple touches. The motion track formed by the backward movement of the control point, the motion track formed by the opposite movements of the plurality of touch points, the motion track formed by the clockwise movement of the plurality of touch points, and the motion track formed by the counterclockwise movement of the plurality of touch points.

The touch control method according to claim 18, wherein, in the step 106, the motion track is a font enlargement touch command generated when a plurality of touch points are moving in a backward motion; When the motion trajectory formed by the movement of the plurality of touch points is opposite to each other, the font reduction touch command is generated; when the motion trajectory is a motion trajectory formed by the clockwise movement of the plurality of touch points, a clockwise rotation touch command is generated; When the trajectory is a motion trajectory formed by moving a plurality of touch points in a counterclockwise direction, a touch instruction that rotates counterclockwise is generated.
