The mouse is an external input device of the computer,

and it is also an indicator of the vertical and horizontal coordinates of the computer display system. It is named after the shape of a mouse (Hong Kong and Taiwan are used as a mouse).

The standard name should be "mouse" and the English name is "Mouse". Using the mouse is to make computer operation easier and faster, rather than complicated keyboard commands.

The mouse was invented in 1964 by Dr. Douglas Engelbart of the University of California, Berkeley.

At the time, Douglas Engelbart was working at the Stanford Research Institute (SRI),

an institution sponsored by Stanford University.

Douglas Engelbart was thinking all along about how to make computer operations easier and what it means to replace cumbersome input with keyboard instruction,

the name at the time of the request is the XY position indicator of the display system.
