In Computing , a mouse (the proper plural form is '''mouses''') functions as a Pointing Device by detecting Two-dimensional motion relative to its supporting surface. Physically, a mouse consists of a small case, held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The mouse's motion typically translates into the motion of a Pointer on a Display . The name ''mouse'', coined at the Stanford Research Institute , derives from the resemblance of early models (which had a cord attached to the rear part of the device, suggesting the idea of a tail) to the common Eponymous Rodent .See, for instance: 1 The first integrated mouse — shipped as a part of a computer and intended for personal computer navigation — came with Xerox Star 1981. TECHNOLOGIES Early mice
Douglas Engelbart of the Stanford Research Institute invented the mouse in 1963 http://www.afrlhorizons.com/Briefs/Mar02/OSR0103.html Retrieved 31 December 2006 http://www.time.com/time/covers/1101041011/nextessay.html Retrieved 31 December 2006 after extensive 2006 Mechanical mice shine through the disks. 5: Sensors gather light pulses to convert to X and Y velocities.]] Bill English , builder of Engelbart's original mouse,2 invented the so-called ball mouse in 1972 while working for Xerox PARC . ''Byte'', issue 9/1981, pp. 58-68 The ball-mouse replaced the external wheels with a single ball that could rotate in any direction. It came as part of the hardware package of the Xerox Alto computer. Perpendicular Chopper Wheel s housed inside the mouse's body chopped beams of light on the way to light sensors, thus detecting in their turn the motion of the ball. This variant of the mouse resembled an inverted Trackball and became the predominant form used with Personal Computer s throughout the 1980s and 1990s. The Xerox PARC group also settled on the modern technique of using both hands to type on a full-size keyboard and grabbing the mouse when required. The ball mouse utilizes two rollers rolling against two sides of the ball. One roller detects the horizontal motion of the mouse and other the vertical motion. The motion of these two rollers causes two disc-like encoder wheels to rotate, interrupting optical beams to generate electrical signals. The mouse sends these signals to the computer system by means of connecting wires. The driver software in the system converts the signals into motion of the mouse pointer along X and Y axes on the screen. Modern computer mice took form at the École Polytechnique Fédérale De Lausanne (EPFL) under the inspiration of Professor Jean-Daniel Nicoud and at the hands of Engineer and Watchmaker André Guignard . http://news.softpedia.com/news/Of-Mice-and-Men-and-PCs-43129.shtml Retrieved 31 December 2006 This new design incorporated a single hard rubber mouseball and three buttons, and remained a common design until the mainstream adoption of the scroll-wheel mouse during the 1990s. 3 Honeywell produced another type of mechanical mouse. |
