鼠标英文称MOUSE,是PC最重要的输入设备之一。鼠标于1968年12月9日诞生在美国加州斯坦福大学,它的发明者是Douglas Englebart博士。Englebart博士设计鼠标的初衷就是为了使计算机的操作更加简便,来代替键盘那繁琐的指令。他制作的鼠标是一只小木头盒子,工作原理是由它底部的小球带动枢轴转动,并带动变阻器改变阻值来产生位移信号,信号经计算机处理,屏幕上的光标就可以移动。随着操作系统广泛采用图形界面,鼠标在各种应用程序中起着越来越重要的作用。
Mouse MOUSE English, is one of the most important PC input devices. The mouse was born on December 9, 1968 at Stanford University in California, USA. Its inventor was Dr. Douglas Englebart. Dr. Englebart designed the mouse in the original intention is to make the operation of the computer easier, instead of the keyboard that tedious instructions. His mouse is a small wooden box, the working principle of which is driven by the bottom of the ball pivot, and lead the rheostat to change the resistance to generate a displacement signal, the signal processed by the computer, the cursor on the screen can move. With the widespread use of graphical interfaces in the operating system, the mouse plays an increasingly important role in a variety of applications.
