083 - What is Computer Mouse

A Mouse is one of the primary input devices used with a computer. Originally referred to as an X-Y Position Indicator for a Display System. Mouse allows an individual to control a pointer in a Graphical User Interface (GUI) and manipulate on-screen objects by pressing scroll, left and rigth button.

A mouse is a hand-operated electronic device that controls the coordinates of a cursor on your computer screen. Computer mouse is a pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface. Mouse consists of an object held in one's hand, with one or more buttons. Anywhere from one to six or more buttons, and usually a scroll wheel, are integrated onto the mouse to provide a wide variety of functions. It is one of the main input device for most computers.

Basic parts of a mouse:

A mouse typically has two buttons: a primary button (left button) and a secondary button (right button). You will use the primary button most often. Most mice also include a scroll wheel between the buttons to help you scroll through documents and webpages more easily. On some mice, the scroll wheel can be pressed to act as a third button. Advanced mice might have additional buttons that can perform other functions.

Types of Computer Mouse:

Mechanical mouse • Houses a hard rubber ball that rolls as the mouse is moved. Sensors inside the mouse body detect the movement and translate it into information that the computer interprets.

Optical mouse • Uses an LED sensor to detect tabletop movement and then sends off that information to the computer for merry munching.

Cordless mouse • With both these types, the mouse relays a signal to a base station wired to the computer's mouse port. The cordless mouse requires power, which comes in the form of batteries.

Multi button mouse • The extra buttons can be programmed to do specific things, such as navigate the Web or turn pages when you’re reading a document.

Trackball mouse • Like an upside-down mouse. Rather than roll the mouse around, you use your thumb or index finger to roll a ball on top of the mouse.

Stylus mouse • Another mouse mutation enjoyed by the artistic type is the stylus mouse, which looks like a pen and draws on a special pad.

Cordless 3-D mouse • This kind of mouse can be pointed at the computer screen like a TV remote.

Mouse is also known as: clicker, pointer, paddle, remote.
