A little more than 40 years ago Douglas Engelbart introduced his "X – Y position indicator for a display system" – more commonly known today as the computer mouse. During a 90-minute presentation on a "computer-based, interactive, multiconsole display system" at the Stanford Research Institute (SRI) in Menlo Park, Calif. This event – attended by some 1,000 computer professionals would later be called by many the "mother of all demos" and would introduce a number of computing capabilities largely taken for granted today: the mouse, hy- pertext, object addressing and dynamic file linking. Engelbart, now 84, filed the patent in 1967 but had to wait three years for the U.S. to acknowledge his technology, which provided the tool needed to navigate graphics-filled computer screens with a simple motion of the hand rather than by wading through screens filled with green-tinted text using keys or a light pencil pressed up against a com- puter monitor. "I don't know why we call it a mouse," he said during the demo. The original mouse housed in a wooden box twice as high as to- day's mice and with three buttons on top, moved with the help of two wheels on its underside rather than a rubber trackball. The wheels – one for the horizontal and another for the vertical – sat at right angles.
