~ The First Computer Mouse ~

The history of the  computer mouse starts at the  Stanford Research Institute in the United States.

The first computer mouse was invented and designed by a man named Douglas Engelbartas, one of the memebers of the Stanford Research Institute.

 It was demonstrated by him in 1968 at the Fall Joint Computer Conference in San Francisco.

The first mouse was bulky, carved out of wood, and only had one button.

 It worked with two metal wheels which made contact with the working surface.

He named it a computer mouse because the cord came out from behind it, resembling a mouse.

Over the next 15 years researchers refined the mouse, making it more flexible and easier to use.

Then in 1972 the ball-mouse was invented by a man named Bill English.

 The ball-mouse was better than the older computer mouse that was invented before, because it contained a single ball instead of the two metal wheels.

 This ball could rotate in any direction.
