The mouse is the external input device of the computer and the indicator of the vertical and horizontal coordinate positioning of the computer display system, so it is named because it looks like a mouse (Hong Kong and Taiwan are mice). Its standard name should be "Mouse" and its English name is "mouse". The use of the mouse is to make the operation of the computer easier and faster, rather than the tedious instructions of the keyboard.
The mouse was invented by Dr. douglas engelbart of the University of California, Berkeley in 1964. At that time, douglas engelbart worked in the Stanford Research Institute (SRI) sponsored by Stanford University. Douglas Engelbart has long been thinking about how to make the operation of the computer easier and what means to replace the tedious instructions entered by the keyboard. When applying for a patent, his name was the X-Y position indicator of the display system.
