The Accessibility Tools are some of the least known applications included in Windows XP. However, that doesn't mean they are not important or useful. Practically these tools are a life-saver for people with disabilities. The Accessibility Tools allows them to adjust settings that make it easier to see their computers, use their mouse and keyboard or other input devices.
In Windows Vista these tools were updated to provide more configuration options. Also, their location and some of the application names were changed.
To find them, go to Start -> All Programs -> Accessories -> Ease of Access.
Here you will find the following tools: Ease of Access Center, Magnifier, Narrator, On-Screen Keyboard and Windows Speech Recognition.
Ease of Access Center is like a Control Panel for all the other accessibility tools. If offers quick access to all the tools and plenty of adjustments options.
The Magnifier, Narrator and the On-Screen Keyboard are pretty much the same as in Windows XP. Windows Speech Recognition is a new tool added in Windows Vista. It allows users to control their computers using their voice. With it, you can say commands that the computer will respond to, and dictate text to the computer.
