Optical mouse device is a kind of hardware device that detects the displacement of mouse by infrared ray or laser, converts the displacement signal into electric pulse signal, and then controls the movement of cursor arrow on the screen through program processing and conversion. The photoelectric sensor of the photoelectric mouse replaces the traditional rolling ball. This sensor needs to be used with special pads with stripes or dot patterns.
The blue mouse is characterized by using blue LED and blue sensor.

This is the most important part of the mouse. Using blue LED with special lens to capture displacement can be used on a series of materials such as transparent glass, white tiles, black tiles, long-haired carpets, mahogany desktops, granite slabs and so on. "blue
"Track" is the Blu-ray mouse technology of Microsoft in the United States, and different companies have different Blu-ray technologies.
The optical engine mouse uses the red visible light source emitted by the light emitting diode, and uses the principle of diffuse reflection of light to record the change of diffuse reflection shadow irradiated by the LED light source on the surface of the object in unit time to judge the movement track of the mouse. Laser engine mouse uses short-wave invisible laser emitted by laser diode. Using the principle that short-wave light is easily reflected, the mouse can clearly image and record the light spots reflected from the surface of the object on the optical sensor. Strictly speaking, both the traditional optical engine and the laser engine should be called optical engines, but two different desktop grasping principles determine that the optical mouse must use a mouse pad, while the laser mouse can be used freely on more surfaces.
Trackball mouse: This kind of mouse is mostly used in notebook computers. It looks like an inverted mechanical mouse, and its internal principle is similar to that of a mechanical mouse.
Its biggest advantage is that it doesn't have to run around like a mechanical mouse, saving space and reducing the fatigue of users' wrists.
Compared with ordinary mouse, trackball has the advantages of accurate positioning and not easy to shake because of its design characteristics, and is suitable for graphic design, 3D design and so on. However, due to this design feature, it is not suitable for general games and other applications.
