What kinds of mice are there and what are their characteristics?
According to its working principle and its internal structure, it can be divided into mechanical type, opto-mechanical type and photoelectric type.
1. Mechanical mouse: The photoelectric pulse signal generated by the grating signal sensor installed at the end of the roller column reflects the vertical and horizontal displacement changes of the mouse, and then the movement of the cursor arrow on the screen is controlled by the processing and conversion of the computer program.
2. Optical mouse:
The optical mouse is an improvement on the basis of a purely mechanical mouse, and the positioning accuracy of the mouse is improved by introducing optical technology.
Like a purely mechanical mouse, the opto-mechanical mouse also has a small glue ball, and is connected to the X and Y shafts. The difference is that the opto-mechanical mouse no longer has a circular decoding wheel, instead it has two A grating code disc with grating slits, and the addition of light-emitting diodes and photosensitive chips.
3. Optical mouse:
By detecting the displacement of the mouse, the displacement signal is converted into an electrical pulse signal, and then the movement of the cursor arrow on the screen is controlled through the processing and conversion of the program.
