Rolling ball mouse: the rubber ball is driven to the grating wheel with light-emitting diodes and phototransistor wafer pulse signal sensor.
The photoelectric mouse technology converts the information of the mouse's movement on the X or Y axis, key presses or lifts into wireless signals and sends them to the host.
The mouse is a very commonly used computer input symbol: a light source pulse signal sensor with a light-emitting semiconductor and a photoelectric sensor that illuminates the particles with a light spot scattered by infrared rays.
Wireless mouse: Using DRF equipment, it can position the cursor on the current screen, and operate the screen elements at the position where the cursor passes through the button and scroll wheel device. The originator of the mouse appeared in 1968. American scientist Douglas Englebart made the first mouse in California.
The mouse is divided into mechanical mouse and optical mouse according to its working principle. The mechanical mouse is mainly composed of roller ball, roller and grating signal sensor. When you drag the mouse, the rolling ball is driven to rotate, and the rolling ball drives the roller to rotate. The grating signal sensor installed at the end of the roller collects the grating signal. The photoelectric pulse signal generated by the sensor reflects the displacement change 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.
