Laser mice use a laser beam to track movement and are becoming more popular due to their better tracking ability and lack of moving parts. Optical mice were introduced in the late 1990s and are now more common than ball mice. Mice were introduced to interact with computers, and using a mouse is often faster and easier than keyboard shortcuts. Laser mice move smoothly and accurately and can reflect off almost any surface, making them versatile.
A laser mouse is a type of computer pointing device that uses a laser beam rather than a ball to track the movement of the user’s hand. This type of mice is becoming more and more common because they are believed to have better tracking ability. Furthermore, they are not subject to rubbering and subsequent signal distortion like conventional ball mice. The lack of moving parts also makes them much less prone to damage.
Before the laser mouse, the optical mouse became popular in the late 1990s, commercializing it as an add-on feature on many computer systems. Users immediately started praising this device, saying that it made work much easier than a traditional mouse, and as a result it is becoming more and more difficult to find a ball mouse. The optical mouse is also available in a wireless format, making it an extremely versatile and flexible tool for users who want to have their cordless desks close at hand.
With the introduction of a graphical user interface in the late 1980s, computer companies saw the need for some sort of device that could be used to interact with the computer, which had transcended the boundaries of the traditional user interface based on text. The mouse was introduced and became a quick success: very few computer users now work without a mouse, although it is technically possible to use keyboard shortcuts to bypass the mouse. However, using the mouse is often faster and easier. As anyone who has used traditional wheeled mice knows, the ball tends to get clogged with material from the work area it’s used in, and can eventually start malfunctioning until it’s disassembled and cleaned. Optical and laser mice were an excellent introduction to the computer world, because they are not subject to interference.
An optical mouse usually uses a light-emitting diode (LED), which is often red, although mice of other colors such as blue are not uncommon. A laser mouse, on the other hand, which is a type of optical mouse, uses a laser beam that is invisible, or nearly invisible, to the human eye. Logitech introduced the first to the market in 2004. The beam emitted by the mouse moves with the user’s hand, activating a system of optical sensors. It works in tandem with a system that keeps track of how far the mouse has moved by bouncing hundreds of images every second, constantly updating the position of the mouse and the next cursor position on the screen.
In general, the laser mouse moves very smoothly and accurately, although if the system memory is bogged down, the cursor will move, along with everything else. Plus, the mouse can reflect off almost any surface, which means you don’t need a mouse pad. Users have been known to use everything from desk tops to pant legs as a reflective surface for their mouse, making it a great tool anywhere.
