Computer Mouse

The first computer mouse was developed around 1964 by Doug Engelbart. Patent filed June 21, 1967, by Doug Engelbart in which he describes the mouse as an X-Y position indicator control for movement by the hand over any surface to move a cursor over the display on a cathode ray tube, the indicator control generating signals indicating its position to cause a cursor to be displayed on the tube at the corresponding position. The indicator control mechanism contains X and Y position wheels mounted perpendicular to each other, which rotate according to the X and Y movements of the mechanism, and which operate rheostats to send signals along a wire to a computer which controls the CRT display.
