Mouse is used as an input device to translate hand movements into signals for the computer to use. It takes into a form of a small, mouse-shaped device that is moved by the hands, it also comes with two clickers, which corresponds to different computer actions. Sometimes, it also has a scroller that enables the user to easily scroll through different files and pages within the screen.
How a mouse works:
- A ball inside the mouse touches the desktop and rolls when the mouse moves.
- Two rollers inside the mouse touch the ball. One of the rollers is oriented so that it detects motion in the X direction, and the other is oriented 90 degrees to the first roller so it detects motion in the Y direction. When the ball rotates, one or both of these rollers rotate as well. The following image shows the two white rollers on this mouse:
- The rollers each connect to a shaft, and the shaft spins a disk with holes in it. When a roller rolls, its shaft and disk spin.
- On the other hand, an optical mouse uses an infrared LED and an infrared sensor. The holes in the disk break the beam of light coming from the LED so that the infrared sensor sees pulses of light. The rate of the pulsing is directly related to the speed of the mouse and the distance it travels.
- An on-board processor chip reads the pulses from the infrared sensors and turns them into binary data that the computer can understand. The chip sends the binary data to the computer through the mouse's cord.
- Logitech is probably the best or at least what the consumers usually choose in the realm of computer mouse, in general. But as for the basic corded mouse, Microsoft seems to be the best choice.
