The plural for the small rodent is always 'mice' in modern usage.

The popularity of wireless mice without cords makes the resemblance less obvious.Īccording to Roger Bates, a hardware designer under English, the term also came about because the cursor on the screen was for some unknown reason referred to as 'CAT' and was seen by the team as if it would be chasing the new desktop device. This likely originated from its resemblance to the shape and size of a mouse, with the cord resembling its tail. The earliest known written use of the term mouse or mice in reference to a computer pointing device is in Bill English's July 1965 publication, 'Computer-Aided Display Control'.

Mice often also feature other elements, such as touch surfaces and scroll wheels, which enable additional control and dimensional input.Įtymology A computer mouse is named for its resemblance to the rodent. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system. Most modern mice use optical movement detection with no moving parts. Later, the standard design shifted to use a ball rolling on a surface to detect motion, in turn connected to internal rollers.

Mice originally used two separate wheels to directly track movement across a surface: one in the x-dimension and one in the Y. The first public demonstration of a mouse controlling a computer system was done by Doug Engelbart in 1968 as part of the Mother of All Demos. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer. For the animal, see Mouse.Ī computer mouse with the most common features: two buttons (left and right) and a scroll wheel (which can also function as a button when pressed inwards) A typical wireless computer mouseĪ computer mouse (plural mice, also mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface.
