In 1964, 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. According to Roger Bates, a hardware designer under English, another reason for choosing this name was because the cursor on the screen was also referred to as “CAT” at this time. By 1963, Engelbart had already established a research lab at SRI, the Augmentation Research Center , to pursue his objective of developing both hardware and software computer technology to “augment” human intelligence.
In 2008, Motion4U introduced its “OptiBurst” system using IR tracking for use as a Maya plugin. 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. Laser diodes provide good resolution and precision, improving performance on opaque specular surfaces. Later, more surface-independent optical mice use an optoelectronic sensor (essentially, a tiny low-resolution video camera) to take successive images of the surface on which the mouse operates.
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. Modern computer mice took form at the École Polytechnique Fédérale de Lausanne under the inspiration of Professor Jean-Daniel Nicoud and at the hands of engineer and watchmaker André Guignard.
- The mouse turns movements of the hand backward and forward, left and right into equivalent electronic signals that in turn are used to move the pointer.

- One exception occurs when the desk surface creates problems for the optical or laser tracking, for example, a transparent or reflective surface, such as glass.
- Microsoft’s mouse shipped in 1983, thus beginning the Microsoft Hardware division of the company.
- Mouse vendors also use other extended formats, often without providing public documentation.
The popularity of wireless mice without cords makes the resemblance less obvious. Signals XA and XB in quadrature convey X-direction motion, while YA and YB convey Y-dimension motion; here the pointer is shown drawing a small curve. Inspired by PARC’s Alto, the Lilith, a computer which had been developed by a team around Niklaus Wirth at ETH Zürich between 1978 and 1980, provided a mouse as well. “Connect a Bluetooth device that does not have or require a transceiver”. Silicon Graphics SpaceBall model 1003 , allowing manipulation of objects with six degrees of freedom. 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 8010 Star in 1981.
With spring-loaded centering, it sends both translational as well as angular displacements on all six axes, in both directions for each. In November 2010 a German Company called Axsotic introduced a new concept of 3D mouse called 3D Spheric Mouse. This new concept of a true six degree-of-freedom input device uses a ball to rotate in 3 axes and an elastic polymer anchored tetrahedron inspired suspension for translating the ball without any limitations. A contactless sensor design uses a magnetic sensor array for sensing three aches translation and two optical mouse sensors for three aches rotation. The special tetrahedron suspension allows a user to rotate the ball with the fingers while input translations with the hand-wrist motion.
However, speed can also refer to the ratio between how many pixels the cursor moves on the screen and how far the mouse moves on the mouse pad, which may be expressed as pixels per mickey, pixels per inch, or pixels per centimeter. Windows also has full support for multiple input/mouse configurations for multi-user environments. While primarily a motion-sensing device , Wii Remote can also detect its spatial position by comparing the distance and position of the lights from the IR emitter using its integrated IR camera . The obvious drawback to this approach is that it can only produce spatial coordinates while its camera can see the sensor bar. More accurate consumer devices have since been released, including the PlayStation Move, the Razer Hydra, and the controllers part of the HTC Vive virtual reality system. All of these devices can accurately detect position and orientation in 3D space regardless of angle relative to the sensor station.

However, the mouse remained relatively obscure until the appearance of the Macintosh 128K (which included an updated version of the single-button Lisa Mouse) in 1984, and of the Amiga 1000 and the Atari ST in 1985. After id Software’s commercial hit of Doom, which did not support vertical aiming, competitor Bungie’s Marathon became the first first-person shooter to support using the mouse to aim up and down. The “invert” feature actually made the mouse behave in a manner that users now regard as non-inverted . Soon after, id Software released Quake, which introduced the invert feature as users now know it.
Bill English, builder of Engelbart’s original mouse, created a ball mouse in 1972 while working for Xerox PARC. The plural for a computer mouse is either “mice” or “mouses” according to most dictionaries, with “mice” being more common. The first recorded plural usage is “mice”; the online Oxford Dictionaries cites a 1984 use, and earlier uses include J.
