Computer mouse Wikipedia. A computer mouse with the most common features two buttons left and right and a scroll wheel, which can also act as a third button. A computer mouse is a hand held pointing device that detects two dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface. The first public demonstration of a mouse controlling a computer system was in 1. Originally wired to a computer, modern mice are often cordless, relying on short range radio communication with the connected system. Mice originally used a ball rolling on a surface to detect motion, but modern mice often have optical sensors that have no moving parts.

Mice often also feature other elements, such as touch surfaces and wheels, which enable additional control and dimensional input. Torrentz will always love you. Farewell. 20032016 Torrentz.

The earliest known publication of the term mouse as referring to a computer pointing device is in Bill Englishs July 1. Computer Aided Display Control. The plural for the small rodent is always mice in modern usage. The plural of a computer mouse is mouses and mice according to most dictionaries, but mice being more common.

HistoryeditThe trackball, a related pointing device, was invented in 1. Ralph Benjamin as part of a post World War II era fire controlradar plotting system called Comprehensive Display System CDS. Benjamin was then working for the British Royal Navy Scientific Service. Cam Open Software Source Webpage there. Benjamins project used analog computers to calculate the future position of target aircraft based on several initial input points provided by a user with a joystick. Benjamin felt that a more elegant input device was needed and invented what they called a roller ball for this purpose. The device was patented in 1. Another early trackball was built by British electrical engineer. Kenyon Taylor in collaboration with Tom Cranston and Fred Longstaff. Taylor was part of the original Ferranti Canada, working on the Royal Canadian Navys DATAR Digital Automated Tracking and Resolving system in 1. DATAR was similar in concept to Benjamins display. The trackball used four disks to pick up motion, two each for the X and Y directions. Several rollers provided mechanical support. When the ball was rolled, the pickup discs spun and contacts on their outer rim made periodic contact with wires, producing pulses of output with each movement of the ball. By counting the pulses, the physical movement of the ball could be determined. A digital computer calculated the tracks and sent the resulting data to other ships in a task force using pulse code modulation radio signals. This trackball used a standard Canadian five pin bowling ball. It was not patented, since it was a secret military project. Early mouse patents. From left to right Opposing track wheels by Engelbart, November 1. U. S. Patent 3,5. Ball and wheel by Rider, September 1. U. S. Patent 3,8. Ball and two rollers with spring by Opocensky, October 1. U. S. Patent 3,9. Douglas Engelbart of the Stanford Research Institute now SRI International has been credited in published books by Thierry Bardini,1. Paul Ceruzzi,1. 2Howard Rheingold,1. Engelbart was also recognized as such in various obituary titles after his death in July 2. By 1. 96. 3, Engelbart had already established a research lab at SRI, the Augmentation Research Center ARC, to pursue his objective of developing both hardware and software computer technology to augment human intelligence. That November, while attending a conference on computer graphics in Reno, Nevada, Engelbart began to ponder how to adapt the underlying principles of the planimeter to X Y coordinate input. On November 1. 4, 1. He wrote that the bug would be easier and more natural to use, and unlike a stylus, it would stay still when let go, which meant it would be much better for coordination with the keyboard. In 1. 96. 4, Bill English joined ARC, where he helped Engelbart build the first mouse prototype. They christened the device the mouse as early models had a cord attached to the rear part of the device which looked like a tail, and in turn resembled the common mouse. As noted above, this mouse was first mentioned in print in a July 1. English was the lead author. On 9 December 1. Engelbart publicly demonstrated the mouse at what would come to be known as The Mother of All Demos. Engelbart never received any royalties for it, as his employer SRI held the patent, which expired before the mouse became widely used in personal computers. In any event, the invention of the mouse was just a small part of Engelbarts much larger project of augmenting human intellect. Inventor Douglas Engelbart holding the first computer mouse,2. Several other experimental pointing devices developed for Engelbarts o. N Line System NLS exploited different body movements  for example, head mounted devices attached to the chin or nose  but ultimately the mouse won out because of its speed and convenience. The first mouse, a bulky device pictured used two potentiometers perpendicular to each other and connected to wheels the rotation of each wheel translated into motion along one axis. At the time of the Mother of All Demos, Engelbarts group had been using their second generation, 3 button mouse for about a year. On October 2, 1. 96. Rollkugel German for rolling ball was described as an optional device for its SIG 1. German company Telefunken. As the name suggests and unlike Engelbarts mouse, the Telefunken model already had a ball. It was based on an earlier trackball like device also named Rollkugel that was embedded into radar flight control desks. This trackball had been developed by a team led by Rainer Mallebrein at Telefunken Konstanz for the German Bundesanstalt fr Flugsicherung as part of their TR 8. SIG 1. 00 8. 62.

Mallebrein and his team came up with the idea of reversing the existing Rollkugel into a moveable mouse like device, so that customers did not have to be bothered with mounting holes for the earlier trackball device. Together with light pens and trackballs, it was offered as an optional input device for their system since 1. Some Rollkugel mouses installed at the Leibniz Rechenzentrum in Munich in 1. Telefunken considered the invention too unimportant to apply for a patent on it. The Xerox Alto was one of the first computers designed for individual use in 1.

The third marketed version of an integrated mouse shipped as a part of a computer and intended for personal computer navigation came with the Xerox 8. Star in 1. 98. 1. By 1. 98. 2, the Xerox 8. The Sun 1 also came with a mouse, and the forthcoming Apple Lisa was rumored to use one, but the peripheral remained obscure Jack Hawley of The Mouse House reported that one buyer for a large organization believed at first that his company sold lab mice.
