Douglas Engelbart’s Demo of The Mouse

The introduction of a new computer inrerface, The Mouse. Prior to the mouse, if you wanted to position your cursor on the screen, it required the equivalent of using up and down arrows to pace up and down, and left and right. “The public presentation was a session of the Fall Joint Computer Conference held at the Convention Center in San Francisco, and it was attended by about 1,000 computer professionals. This was the public debut of the computer mouse. But the mouse was only one of many innovations demonstrated that day, including hypertext, object addressing and dynamic file linking, as well as shared-screen collaboration involving two persons at different sites communicating over a network with audio and video interface. “
