Remote control system and method for computer

A remote control method for a computer, comprising:

• (a):
• moving a label device;
• (b):
• capturing images of the label device through a camera at an preset time interval and sending the images to a signal processing module;
• (c):
• obtaining a movement distance and a movement time of the label device according to the received images by the signal processing module, and comparing the movement distance with first and second preset distances and comparing the movement time with first and second preset time stored in a signal processing module by the processing module;
• (d):
• determining whether the movement distance is less than the first preset distance and whether the movement time is less than the first preset time;
• (e):
• outputting a first instruction to control the cursor in response to the movement distance being less than the first preset distance and the movement time being less than the first preset time, and then the procedure going back to step (b);
• (f):
• determining whether the movement distance is greater than the first preset distance and less than the second preset distance, and the movement time is greater than the first preset time and less than the second preset time, in response to the movement distance being not less than the first preset distance and the movement time being not less than the first preset time;
• (g):
• outputting a second instruction to control the cursor in response to the movement distance being greater than the first preset distance and less than the second preset distance, and the movement time being greater than the first preset time and less than the second preset time, and then the procedure going back to step (b);
• (h):
• determining whether a track of the movement distance is a circle in response to the movement distance being greater than the second preset distance and the movement time being greater than the second preset time;
• (i):
• outputting a third instruction to control the cursor in response to the track of the movement distance being not a circle, and then the procedure going back to step (b);
• and
• (j):
• outputting a fourth instruction to control the cursor in response to the track of the movement distance being a circle, and then the procedure going back to step (b).
