If it is the former, it is determined as the starting point of the touch operation, and step 204 is performed; if the latter, the touch position is determined to be a continuation of the current touch operation, and step 205 is performed. In step 204, a cursor moving speed is determined according to the touch position where it is located. Since the touch position is the starting point of the touch operation, the cursor moving speed of the corresponding cursor on the display during the touch operation is also determined. There are various ways for the microprocessor 130 to determine the moving speed of the cursor. In this embodiment, A table look-up corresponding manner may be employed, but is not limited to this manner. In step 205, since it is a continuation point of the current touch operation, using the current touch position and the relative position and orientation at the starting point, and determining the moving speed of the cursor by the starting point, a cursor is obtained. Moving distance. Step 206 is to transmit the data obtained in step 204 or step 205 to the display through the transmission module 140, and return to step 201 until the end of the touch operation, that is, the user's finger leaves the touch panel.

It should be noted that in the present invention, the touch moving speed is determined according to the position of the starting point of the touch operation on the touch panel. Therefore, the touch surface of the touch panel 110 of the present invention can be divided into a plurality of regions, which respectively correspond to different cursor moving speeds, and the user can drop the finger in the corresponding cursor according to the desired moving speed of the cursor. In the area, when you start the touch operation, you can reduce the moving speed of the cursor and perform detailed and precise operations. The third figure shows a schematic diagram of an embodiment of the division of the touch area of the touch panel of the touch panel of the present invention. As shown in the third figure, the surface of the touchpad can be divided into concentric square-shaped areas, labeled A, B, C, and D, respectively, corresponding to different cursor moving speeds, for example, from D area to A area. Decrease in sequence. When the user starts the touch operation, if the finger falls in the D area, the moving speed of the cursor can be set to be the fastest. If the user wants to reduce the speed of the cursor for precise operation, the user can start the touch operation and drop his finger in the C area, the B area, or even the A area.
