Microsoft continues to work with assistive technology companies and to incorporate accessible features into the company's products. Here are a few of Windows 2000 Professional's accessibility features: On Screen Keyboard displays a virtual keyboard on the computer screen that enables people with mobility impairments to type data by using a pointing device or joystick. Magnifier is a display utility that makes the computer screen more readable for people who have low vision. Magnifier creates a separate window that displays a magnifier portion of the screen. Narrator is a text-to-speech utility for people who are blind or have low vision. Narrator reads what is displayed on the screen - the contents of the active window, menu options or text that has been typed. SerialKeys allows the use of alternative input devices instead of a keyboard and mouse. ShowSounds instructs programs to display captions for the speech and sounds they make.
