Still being so simple, the mouse occupies a privileged place in the world of computer accessories.
It appeared in the market in 1981 and it was popularized in 1984 with the Macintosh. Since its birth, in 1963, it's basic method of operation is the same nowadays. It has been improved in the mechanics and the ergonomics. The main improvements have been in the detection of the movement and the resolution.
Although there still seems to be more room for improvements. The elimination of the annoying cable: the wireless mouse has been born.
A wireless mouse require two components to work: a Radio transmitter and a Radio receiver.
The receiver station uses a PS/2 or USB connection to plug into the computer. The mouse houses the transmitter, and relies on batteries for its power (alkalines or rechargeables). When the mouse detects movement or button clicks, sends this information via radio signals to the receiver. The receiver decodes the signal and sends these to the computer.
To be able to transfer data at high speed and to have little or no interference in a work or home environment, the working frequency is of 2.4 gigahertz.
Bluetooth is a telecommunications specification that describes how different types of components can communicate with each other. This technology uses adaptive frequency hopping, a software that helps the device to automatically choose a radio frequency that has the least amount of traffic.
Bluetooth has become a standard and many laptops incorporates a Bluetooth receiver, so that you only need a Bluetooth mouse.
Wireless mice are generally more reliable, lightweight and cheaper than mechanical mice.
