Window xp lesson 12

Accessibility and the Accessibility Options Dialog Box

As you know, a computer functions with both input (keyboard and mouse, for example) and output (monitor and printer, for example) devices. In this lesson, we'll focus on how Windows XP allows you to configure your computer's input and output behaviors to accommodate people with a range of disabilities.
To access the Accessibility Options dialog box:

* Open the Control Panel.
* Click the Accessibility Options link.

Accessibility Options link

* Under Or pick a Control Panel icon, click the Accessibility Options link.
* The Accessibility Options dialog box opens

Adjusting the Keyboard


When you open the Accessibility Options dialog box, notice that it is equipped with five tabs: Keyboard, Sound, Display, Mouse, and General.

The Keyboard tab allows you to change the way your keyboard inputs information into Windows XP.

Accessibility Options dialog box
The following features are especially helpful for users who have difficulty using the keyboard.

StickyKeys. Enable StickKeys so you don't have to hold down several keys at once on the keyboard. For example, if you want to use Control + Alt + Delete, StickKeys allows you to press one key at a time rather than having to hold them down all at once. To use StickKeys, check the Use StickyKeys box and press the Settings button to adjust your personal settings. Once you enable or disable these, you can use them by pressing the Shift key five times in a row.

Filterkeys. Enable FilterKeys to ignore brief or repeated keystrokes. To use FilterKeys, click the Use Filterkeys checkbox and click the Settings button to adjust your personal settings.

Togglekeys. Enable ToggleKeys if you want to hear tones when pressing CAPS LOCK, NUM LOCK, and SCROLL LOCK. To use ToggleKeys, click the Use ToggleKeys checkbox and click the Settings button to adjust your personal settings.

Adjusting the Sound

The Accessibility Options Sound tab allows you to enable Windows sounds to help you operate Windows XP.

Accessibility Options dialog box
These features are especially helpful for users who are hearing impaired. Choose from two options:

SoundSentry. Windows XP uses sound to alert the user to certain warnings or notices. Sound Sentry enables these warnings to appear on your screen instead of as a sound. To use Sound Sentry, click the Use SoundSentry checkbox. Then choose the kind of visual warning you want to receive.

ShowSounds. Use ShowSounds to tell any programs to show text for any sounds or speech they may use. To use ShowSounds, click the Use ShowSounds checkbox.

Adjusting the Display

The Display tab allows you to use high-contrast colors and adjust the cursor to make reading easier.
These features are especially helpful for users who are visually impaired. Choose from two options:

To enable High Contrast, click the Use High Contrast checkbox. Clicking the Settings button enables the shortcut for High Contrast, ALT+SHIFT+PRINT SCREEN.

Use the sliders to change the cursor blink rate and the width of the cursor.

Using MouseKeys

The Mouse tab allows you to use the numeric keypad on your keyboard to control the pointer. To use MouseKeys, click the Use MouseKeys checkbox. Clicking the Settings button enables the shortcut for MouseKeys, LEFT ALT+LEFT SHIFT+NUM LOCK.

Notification. Receive a warning when turning a feature on or make a sound when turning a feature on or off.

SerialKeys. Turn on SerialKeys so other input devices (other than the traditional keyboard and mouse) can work with Windows XP.

Administrative options. Computer administrators can apply all accessibility options to the logon desktop and apply all accessibility settings for each new user.
