Computer peripheral devices that are hand-operated electronic devices used to control the coordinates of a cursor on the screens of computers, workstations, or other computerized equipment or systems. These computer input mice typically consist of handheld or hand-guided pointing devices used on a mouse pad or on a desktop to move a cursor on a computer screen to point to and click on various data elements within a computer program. They typically include a right and left button and a scroll wheel, and are used to navigate around a computer program or web page. A variety of computer input mice are available according to the intended use, such as mechanical (using an internal ball on two rollers) and optical (which tracks mouse movement through sensing the small, red light-emitting diode light reflecting off a surface onto a complimentary sensor). Applications of specific computer mouse devices include data input for computers, workstations, and computerized systems, often as an integral component of computers (e.g., laptop computers) and other computerized systems. Computer input mice can be either plugged into the computer system or can be operated wirelessly. There are computer input mice that are washable, fully sealed, waterproof, and/or flexible and that can be easily cleaned and disinfected.
