Modern mice have three buttons: left button, right button, scroll button.

Most mice have two buttons to click. Due to the incompatibility between the two protocols, some manufacturers sold serial mice with a mode switch: "PC" for MSC mode, "MS" for Microsoft mode. The Xerox PARC group also settled on the modern technique of using both hands to type on a full-size keyboard and grabbing the mouse when required. Below is a general overview of the parts found on most computer mice. Because a laptop is designed for portability almost all laptops today use a touchpad as the mouse, and some Lenovo laptops still use a TrackPoint. Moving the mouse turns the ball. For other uses, see Spaceball disambiguation. Infrared LEDs shine through the disks. In those days, computers were large and expensive.

There are three basic types of mice Mechanical: Has a rubber or metal ball on its underside that can roll in all directions. History of the Computer Mouse Invented by Douglas Engelbart of Stanford Research Center in , and pioneered by Xerox in the s, the mouse is one of the great breakthroughs in computer ergonomics because it frees the user to a large extent from using the keyboard. Cordless mice instead transmit data via infrared radiation see IrDA or radio including Bluetooth , although many such cordless interfaces are themselves connected through the aforementioned wired serial buses.

The most common models manufactured by Logitech and Gyration work using 2 degrees of rotational freedom and are insensitive to spatial translation. After studying and designing for a long time, Engelbart succeeded in inventing an input device which he named 'XY index'.

Main article: Optical mouse Optical mice rely entirely on one or more light-emitting diodes LEDs and an imaging array of photodiodes to detect movement relative to the underlying surface, eschewing the internal moving parts a mechanical mouse uses in addition to its optics.

five uses of computer mouse

Mouse use in DOS applications became more common after the introduction of the Microsoft Mouselargely because Microsoft provided an open standard for communication between applications and mouse driver software.

This command line interface is still used by some people, such as programmersto get things done faster.
