Introduction to Accessibility Options (Windows)
Windows XP, Vista, and 7 include built-in accessibility settings and programs that make it easier to see, hear, and use the computer. The accessibility settings and programs in Windows Vista are particularly helpful to people with visual difficulties, hearing loss, discomfort in their hands or arms, or reasoning and cognitive issues. The Ease of Access Center makes it easier to find and use accessibility settings.
To open the Ease of Access Center, press:
- Windows logo key

Magnifier Enlarge a portion of the screen to make things easier to see with Magnifier. Choose a magnification level from 2 to 16 times the original and choose to track the mouse, the keyboard, or text editing.
Narrator A text-to-speech program that reads aloud on-screen text and describes some events (such as error messages) that happen while you're using the computer. Narrator in Windows Vista now reads Narrator menus without leaving the active window and has a natural sounding voice.

Introduction to Accessibility Options (Mac)
Mac OS X comes with a variety of assistive technologies to help those with vision disabilities, including a built-in screen reader, screen and cursor magnification, high-contrast settings, and more.
VoiceOver Every new Mac includes an advanced, full-featured screen-access technology that makes it possible for those who are blind or have low-vision to control their computer. It’s called VoiceOver and it’s built into the Mac OS X operating system, so it’s preinstalled and ready to use right out of the box. VoiceOver is much more than simply a text-to-speech tool. It uses speech to describe what is happening on your computer, and you can use it to control the computer without seeing the screen.
Screen Magnification Zoom is a built-in, full-screen magnifier that can magnify the items on the screen up to 40 times. You can activate it using keyboard commands, a button on the screen, a trackpad gesture, or the scroll ball (or wheel) on a mouse. Thanks to the powerful Quartz rendering engine in Mac OS X, text, graphics, and even motion video can be magnified without affecting system performance.
High Contrast and Reverse Video Mac OS X includes flexible adjustments for changing the characteristics of your display. There are settings to increase and decrease contrast, remove color (switch to grayscale) and even reverse the video to white-on-black or black-on-white. These settings do not rely on applications to support them, and they also apply systemwide so you are assured of a consistent view in every application.
