On December 9, 1968, the world's first mouse was born at Stanford University in California, USA. Its inventor was Dr. Douglas Englebart. Dr. Englebart's original intention of designing the mouse was to make computer operation easier and replace the cumbersome instructions on the keyboard. The mouse he made is a small wooden box. The working principle is that the small ball at the bottom drives the pivot and drives the rheostat to change its resistance to generate a displacement signal. After the signal is processed by the computer, the cursor on the screen can move. Since then, the mouse and the PC have formed an indissoluble bond that is difficult to express in words.
