How the mouse works

Rolling ball mouse:The rubber ball is transmitted to the grating wheel with the light-emitting diode and the photo transistor of the photo transistor.

 

　　Optical mouse:Infrared-scattered light spot illuminating particles with a light source pulse signal sensor of a light-emitting semiconductor and a photoelectric sensor.

 

　　Wireless mouse:Use DRF technology to convert the mouse's movement on the X or Y axis,button press or lift information into a wireless signal and send it to the host.

 

　　The mouse is a very common computer input device that can position the cursor on the current screen and operate the screen elements of the position where the cursor passes by the button and scroll wheel device.The originator of the mouse appeared in 1968,and American scientist Douglas Englebart made the first mouse in California.

 

　　The mouse is divided into a mechanical mouse and an optical mouse according to the working principle of the mouse.The mechanical mouse is mainly composed of a rolling ball,a roller column and a grating signal sensor.When you drag the mouse,the ball is rotated,the roller moves the roller,and the grating signal sensor at the end of the roller collects the grating signal.The photoelectric pulse signal generated by the sensor reflects the displacement of the mouse in the vertical and horizontal directions,and then the movement of the cursor arrow on the screen is controlled by the processing and conversion of the computer program.
