The first public demonstration of a mouse controlling a computer system was in 1968. Originally wired to a computer, many modern mouse are cordless, relying on short-range radio communication with the connected system. Mouse originally used a ball rolling on a surface to detect motion, but modern mouse often have optical sensors that have no moving parts. In addition to moving a cursor, computer mouse have one or more buttons to allow operations such as selection of a menu item on a display. Mouse often also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input.
