Workflow: LED (light)-desktop-optics-optical sensor (SENSOR)-main control chip (MCU)-RF IC-antenna-antenna-PC-RF IC-USB main control chip-USB lines screen coordinates.

Mouse mobile Shi optical sensor in constantly of collection desktop Shang each a points, will collection of points bit sent to main control chip for memory and compared next points of bit poor, main control chip will compared out of displacement signal conversion for corresponding of interface information through RF IC adjustable made wireless carrier signal through wire launches out, received device through antenna received to corresponding of wireless carrier signal, after RF IC modulation detection out corresponding of interface information to USB main control chip, main control chip conversion into USB signal, Transmitted through the USB cable to your computer, so as to achieve the cursor moves up and down movements.
