One of the most important developments in computer ergonomics, the computer mouse, has redefined the PC-Human interactions since it was first introduced publicly by Apple Macintosh in 1984.

Invented by Douglas Engelbart of Stanford Research Center, this palm-sized device has become such an inherent part of our computing life that we notice it only when it behaves erratically or stops functioning at all.

This pointing device, which derives its name from its shape that resembles a mouse is used to control the movement of an object called the cursor or pointer on the display screen.

A computer mouse translates the motion of your hand into signals that the computer can use.

Most wired mice use a USB connector to attach to computers while some older mice use a PS/2 or a serial type of connector to attach to computers. On the other hand Cordless or wireless mice use radio frequency (RF) technology to communicate with the computers.

Over the years computer mice have evolved to cater to our different computing interaction needs and any problem of this vital peripheral can bring our computing life to standstill.
