Meet the optical mouse: a revolutionary device that eliminates sticky roller wheels, dirty sensors and irritating banging just to get your mouse to work. Gone are the days when you had to worry about opening a mouse to clean the scroll ball or sensors; the optical mouse makes all this bother obsolete by using imaging technology.
What Is an Optical Mouse?
An optical mouse doesn't use sensor bars and a roller ball like a mechanical mouse. Instead, it bounces light off a surface to determine where it's located and whether or not you've moved the mouse. Because an optical mouse works using a CMOS light sensor, you don't have to worry about any moving parts. Desktop dirt and dust can still block the lens, but this is easily wiped off and you don't need to take the mouse apart to do it.
Optical mice are ideal in households with pets, because you don't have to worry about dirt or fuzz accumulating and clogging the mouse sensors. They're also great if you have an aversion to dusting, and you tend to accumulate fuzz or dirt on your desktop. You can use an optical mouse in a workshop or other area prone to dust or smoke without worrying about the mouse getting gummed up or having to clean it every couple of days.
Pictures Become Movement
An optical computer mouse works by bouncing light off a surface and taking hundreds of pictures per second to determine whether the surface has changed. The digital signal processor analyzes the pictures and measures the change in the surface, which translates to how far and in what direction you've moved the optical mouse. Because the mouse works from hundreds of pictures per second, the cursor appears to move very smoothly and you don't have a jumpy, juddering motion.
This means that you can use an optical mouse anywhere. Because it doesn't require contact with a slightly soft, tactile surface to manipulate a scroll ball, you can use an optical mouse on any surface, as long as its not transparent. You don't need a mouse pad or even desk space; you can use an optical mouse on a book, your lap or any other relatively flat surface that can hold it. An optical laptop mouse is a great traveling companion for your laptop.
Precision and Control
Because an optical mouse can detect very small movements, this type of mouse offers superior precision and fine control over your mouse functions. Cursor movement is very smooth, enabling you to be much more precise than you would with a mechanical mouse. Gamers and graphic designers prefer the optical mouse because of its superior precision and fine control.
