[89] Windows 2000 and Windows Me expanded this built-in support to 5-button mice. Later, inspired by the Star, Apple Computer released the Apple Lisa, which also used a mouse. A sensitivity converter is required in order to translate rotational movements properly.[107]. In 2000, Logitech introduced a "tactile mouse" that contained a small actuator to make the mouse vibrate. This wireless mouse was worn on a ring around a finger, which enabled the thumb to access three buttons. Several rollers provided mechanical support. Moving the pointer a long distance: When a practical limit of mouse movement is reached, one lifts up the mouse, brings it to the opposite edge of the working area while it is held above the surface, and then replaces it down onto the working surface. William Kirk English was born on Jan. 27, 1929, in Lexington, Ky., the only son of Harry and Caroline (Gray) English. The original mouse had the cord in front, but they quickly moved it to the back end to get it out of the way. Hence, cordless mice did not get traction until this problem was solved. Mickeys per second is a unit of measurement for the speed and movement direction of a computer mouse,[77] where direction is often expressed as "horizontal" versus "vertical" mickey count. After receiving a doctorate in electrical engineering from the University of California, Berkeley, in 1955, he stayed on as an acting assistant professor for a year before accepting a position with the Stanford Research Institute (SRI; now SRI International) in Menlo Park, California. It is interesting, that the inventor of one of the most popular computer interface devices ever in the world didn't received any royalties for his mouse invention. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. The earliest optical mice detected movement on pre-printed mousepad surfaces, whereas the modern LED optical mouse works on most opaque diffuse surfaces; it is usually unable to detect movement on specular surfaces like polished stone. Benjamin felt that a more elegant input device was needed and invented what they called a "roller ball" for this purpose. April 18, 2005. For the San Francisco event, he used a video projector the size of a Volkswagen Beetle (borrowed it from a nearby NASA lab) to arrange and project the live images behind Mr. Engelbart as he demonstrated NLS from the stage. Since around the late 1990s, the three-button scrollmouse has become the de facto standard. He was one of the computing pioneers who “showed what a computer interface could — and should — look like,” a colleague said. Whether to use a hard or soft mousepad with an optical mouse is largely a matter of personal preference. Multiple mice are often used in multi-user gaming in addition to specially designed devices that provide several input interfaces. Mouse Systems). (Sept. 14, 2012) http://sloan.stanford.edu/mousesite/1968Demo.html, University of California, Berkeley.

However, a few gestural conventions have become widespread, including the drag and drop gesture, in which: For example, a user might drag-and-drop a picture representing a file onto a picture of a trash can, thus instructing the system to delete the file. Thus, a small but fast movement (known as "flick-shotting") using a gamepad requires the player to quickly move the stick from its rest position to the edge and back again in quick succession, a difficult maneuver. For example, on platforms with more than one button, the Mozilla web browser will follow a link in response to a primary button click, will bring up a contextual menu of alternative actions for that link in response to a secondary-button click, and will often open the link in a new tab or window in response to a click with the tertiary (middle) mouse button. In addition the stick also has a finite magnitude; if the player is currently using the stick to move at a non-zero velocity their ability to increase the rate of movement of the camera is further limited based on the position their displaced stick was already at before executing the maneuver. Bill English, Engelbart's lead engineer, testing the first mouse and keypad (source www.dougengelbart.org). A Microsoft IntelliMouse relies on an extension of the PS/2 protocol: the ImPS/2 or IMPS/2 protocol (the abbreviation combines the concepts of "IntelliMouse" and "PS/2"). In the late 1950s, after leaving a career in the Navy, Mr. English joined a Northern California research lab called the Stanford Research Institute, or S.R.I. Palm Grip: the hand rests on the mouse, with extended fingers. Sept. 1, 2006. [48] In 1985, René Sommer added a microprocessor to Nicoud's and Guignard's design. Starting with Windows XP, Microsoft introduced an SDK for developing applications that allow multiple input devices to be used at the same time with independent cursors and independent input points. Because the IBM PC did not have a quadrature decoder built in, early PC mice used the RS-232C serial port to communicate encoded mouse movements, as well as provide power to the mouse's circuits. Some mice may include several different rests with their products to ensure comfort for a wider range of target consumers. Some designs attempt to place the palm more vertically, so the bones take more natural parallel position. For the pointer it controls, see, Pointing device used to control a computer, "SpaceBall" redirects here. This control system resembles that of aircraft control sticks, where pulling back causes pitch up and pushing forward causes pitch down; computer joysticks also typically emulate this control-configuration. They required the ability to interact with information displays using some sort of device to move a cursor around the screen. Douglas Engelbart, inventor of the computer mouse, passed away earlier this week in his California home, The Register reports. [clarification needed][citation needed]. The engineer and researcher William English testing the first computer mouse, a device envisioned by his colleague Douglas Engelbart. From his early vision of turning organizations into augmented knowledge workshops, he went on to pioneer what is now known as collaborative hypermedia, knowledge management, community networking, and … In early 1967 Engelbart and Bill English published a paper, discussing this test also referred to a “knee-control” device that appeared promising.
