What Does a Computer Mouse Do

What does a computer mouse do? Your mouse provides an easy point-and-click interface with your computer. However, different mice work in different ways, so select the mouse whose computing style works best for your needs.

A mouse provides an easy graphical interface.
Without a computer mouse, you'd need to remember difficult keyboard shortcuts to perform any function on your computer. With a mouse, you simply move the physical mouse around until the arrow on the screen matches the object you want to select, and click away. Mice are infinitely customizable, and they provide the easiest possible way to interact with your computer.

You can calibrate your mouse to be as sensitive or as slow as you'd like.
Calibration changes how your physical mouse interacts with your computer. If you feel like you have to make big, clumsy swipes with the mouse to move the arrow, you can calibrate your mouse to be more sensitive. On the other hand, if you feel like every tiny movement of the mouse sends your arrow darting across the screen, you can reduce the sensitivity and tone down your mouse.

Finally, if your mouse moves too quickly for you to follow, you can program it to move slower, or to give you a longer interval that gives you time to perform a double-click. Mouse calibration enables you to use your mouse in whatever manner suits you best, so calibrate your mouse if you're having trouble.

To calibrate your mouse, consult your manufacturer's instructions, or go into your Control Panel on your computer. Some mice come with custom software to control mouse functionality, but you may also be able to adjust your mouse settings from the Control Panel by selecting the Mouse icon.

A trackball computer mouse is a different kind of mouse.
While most mice require you to move the mouse around physically in order to move the arrow on the screen, a trackball computer mouse is a stationary mouse. With a trackball mouse, the mouse sits in a fixed position, and you scroll a large ball to move the arrow on the screen. The trackball computer mouse is theoretically more ergonomic than regular computer mice, and it may be a good choice for people with arthritis, carpal tunnel or other hand-related problems.

A wireless computer mouse is ideal for laptops and helps avoid annoying entanglements.
A wireless computer mouse is exactly how it sounds; a mouse with no wires to get tangled up or restrict your mouse's movement. A wireless computer mouse still has an adaptor that plugs into the back of the computer where your mouse would normally connect, but it has a wireless receiver that sits somewhere on your desk instead of connecting directly to your mouse. Your mouse then transmits signals back and forth with the wireless receiver to move the arrow around the screen. Wireless computer mice don't get their power from the computer, so you may need to change batteries periodically, or you might want to look for a rechargeable model so you don't have to worry about battery power.
