Computer expert Douglas Engelbart developed the idea for the mouse in the early nineteen-sixties. The first computer mouse was a carved block of wood with two metal wheels. It was called a mouse because it had a tail at one end. The tail was the wire that connected it to the computer.十九世纪六十年代早期,计算机专家道格拉斯.恩格尔巴特提出了鼠标的概念.全球第一个鼠标是一个有着两个金属轮子的木雕制品.因为它在一端有条尾巴而被称为鼠标,这个尾巴就是连接计算机的数据线.
