Computer mouse

In 1968, the first demonstration of the use of a computer mouse was given at the American Federation of Information Processing Societies' Fall Joint Computer Conference at Stanford University, California. The mouse's inventor, Doug Engelbart and a small team of researchers from the Stanford Research Institute stunned the computing world with an extraordinary demonstration at a San Francisco computer conference. They debuted the computer mouse, graphical user interface, display editing and integrated text and graphics, hyper-documents, and two-way video-conferencing with shared workspaces. These concepts and technologies were to become the cornerstones of modern interactive computing. Engelbart patented the mouse on 17 Nov 1970.
