The editor will share with you what kind of device the mouse is in the computer. I hope you will get something after reading this article. Let's discuss it together.

The mouse is a kind of external input device of the computer, and it is also an indicator of the vertical and horizontal coordinate positioning of the computer display system, which is named because it is shaped like a mouse; the mouse can locate the cursor on the current screen. and through the keys and wheel device to operate the screen elements of the position of the cursor.

The mouse is a computer external input device.

The mouse, an external input device of the computer, is also an indicator of the vertical and horizontal coordinates of the computer display system. It is named because it looks like a mouse (RTHK is a mouse). Its standard name should be "mouse", English name "Mouse". The use of the mouse is to make the operation of the computer easier and faster, instead of the tedious instructions of the keyboard.

The mouse was invented in 1964 by Dr. Douglas Engelbart (Douglas Engelbart) of the University of California, Berkeley, when Douglas Engelbart worked at the Stanford Research Institute (SRI), an institution sponsored by Stanford University. Douglas Engelbart had long considered how to make computers easier to operate and what means to replace the cumbersome instructions entered by the keyboard. The name of the patent application is the display system Xmury position indicator.

working principle

Ball mouse: a crystal element pulse signal sensor for rubber ball transmission to grating wheel light-emitting diode and photosensitive transistor.

Optical mouse: infrared scattered spot irradiating particles with light emitting semiconductors and photoelectric sensors light source pulse signal sensor.

Wireless mouse: using DRF technology to convert the information of mouse movement, button pressing or lifting on the X or Y axis into a wireless signal and send it to the host computer.

The mouse is a very commonly used computer input device, which can locate the cursor on the current screen and operate the screen elements of the cursor through keys and wheel devices. The ancestor of the mouse appeared in 1968, and American scientist Douglas Engelbart (Douglas Englebart) made the first mouse in California.

According to the different working principle, the mouse is divided into mechanical mouse and optical mouse. The mechanical mouse is mainly composed of ball, roller and grating signal sensor. When you drag the mouse, the ball rotates, and the ball rotates the roller, and the raster signal sensor installed at the end of the roller collects the raster signal. The photoelectric pulse signal generated by the sensor reflects the vertical and horizontal displacement 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.

After reading this article, I believe you have a certain understanding of "what kind of device the mouse is in the computer". If you want to know more about it, you are welcome to follow the industry information channel. Thank you for reading!
