Mice often also feature other elements, such as touch surfaces and scroll wheels, which enable additional control and dimensional input.Ī 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 selection of a menu item on a display. Though originally all mice were connected to a computer by a cable, some modern mice are cordless, relying on short-range radio communication with the connected system. Most modern mice use optical sensors that have no moving parts. Later, the standard design shifted to utilise a ball rolling on a surface to detect motion. Mice originally used two separate wheels to 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 in 1968. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer. A computer mouse (plural mice, sometimes mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface.
