Computer Mouse

Your main tool for accessing your computer’s information

A computer mouse is an input device that allows you to access icons, programs, links and more on your computer screen. Mice work as pointers – with one click, you can open new pages on the Internet, select what you want on the computer screen, and highlight, copy and paste text to where you need it to go.

Mice come in two different forms. You can buy a trackball mouse, which allows the device to move by means of a ball on its base. However, these are quickly going out of style and are being replaced by another model: the optical mouse. This mouse uses a laser sensor to move the pointer around. Unlike a trackball, which needs a mouse pad and regular cleaning in order to ensure the mouse moves smoothly, an optical mouse can be used on any surface and never needs cleaning.

You can also find mice that don’t need to be moved on a surface at all. These mice are moved in the air and allow you to control the cursor using 3D movements. Most devices are a form of USB mouse, which means that they use a USB port to connect to your computer. Also, mice come in different sizes. For example, if you have a laptop, you can buy a smaller mouse.

Mice can come with different features, too. For example, a wireless mouse can be used on any surface, as long as it has a direct line to its wireless adapter. A Bluetooth mouse, which is a specialized version of a wireless mouse, can be used anywhere without an adapter as long as the computer is near. An ergonomic mouse allows you to comfortably position your hand and wrist movements so that you can use the mouse without pain. Most mice come with a scroll wheel or scroll trackball to make navigating through Web pages and documents easier.

Must-Have Features

  • A scroll wheel for easier movement.
  • A USB hookup – most computers will not include a PS/2 hookup for a mouse.
  • An optical laser sensor to reduce cleaning and eliminate the need for a mouse pad.
  • A middle button or the ability to depress the scroll wheel.
  • A comfortable range of motion.

Major Considerations

  • What will I use my mouse for? Will I need it for gaming or other applications that need an adjustable optical laser sensor?
  • Will I use my mouse a lot? Would an ergonomic model be better?
  • Do I want a wireless model?
  • What size do I want my mouse to be?

Summary

A computer mouse is important to get the most out of your computer. Trackball and optical mice are both available, but an optical laser sensor mouse will last longer and need less maintenance. Wireless mice are more expensive but tend to be easier to use. Mouse features can include scroll wheels, middle buttons and more. What you choose will depend on your computer needs.
