What is hid-compliant mouse?

The types of these two mice are as follows:

1. HID-compliant mouse is an external optical mouse for computers.

2. PS/2-compatible mouse has two definitions: it is defined as an old-fashioned round-mouth external mouse on desktop computers, which is called PS/2 interface mouse. , defined as notebook touchpad on notebooks.

Extended information

The working principle of the mouse

1. Rolling ball mouse: the rubber ball is transmitted to the grating wheel with light-emitting diode and photosensitive Transistor chip pulse signal sensor.

2. Optical mouse: A light source pulse signal sensor with a light-emitting semiconductor and a photoelectric sensor that irradiates particles with infrared scattered light spots.

3. Wireless mouse: Use DRF technology to convert the mouse movement on the X or Y axis, button press or lift information into wireless signals and send them to the host.

4. The mouse is a very commonly used computer input device. It can position the cursor on the current screen and operate the screen elements at the location passed by the cursor through buttons and wheel devices.

5. The originator of the mouse appeared in 1968, when American scientist Douglas Englebart made the first mouse in California.

6. Mouse is divided into mechanical mouse and optical mouse according to its different working principles. Mechanical mouse is mainly composed of rolling ball, roller and grating signal sensor.

7. When the mouse is dragged, the rolling ball is driven to rotate, and the rolling ball in turn drives the roller to rotate. The grating signal sensor installed at the end of the roller collects the grating signal.

8. The photoelectric pulse signal generated by the sensor reflects the displacement changes of the mouse in the vertical and horizontal directions, and then is processed and converted by the computer program to control the movement of the cursor arrow on the screen.
