Accessibility on Public Access Computers

The Bill & Melinda Gates Foundation is committed to making public access computing available to everyone. The Bigprint profile was created with this in mind. Because there is a broad range of accessibility issues we were not able to address every issue, but we have worked with the Washington Assistive Technology Alliance to create a profile that works for many. The Bigprint profile is available as an option on all U.S. Library Program granted computers.

Log On To The Bigprint Profile

1. If you are logged on to the computer in a profile other than Bigprint, click Start and select Log Off. Click Yes to log off Windows.

2. Type Bigprint in the User name box. Click OK.

  •  Accessibility testing has shown a dark (blue) background with white text to be easier to read than dark text on a white background.
  • Only programs that work with accessibility tools are available in Bigprint.

Options For People with Vision Impairments

The Magnifier and Display Options modifications can assist patrons and staff that have vision problems to use Public Access Computers.

Using the Magnifier

The Magnifier enlarges the active part of the screen for easier viewing. You can modify the magnifier by:

  • changing the size and placement of the magnifier window
  • modifying the magnification settings

To Change Size of the Magnifier Window

The Magnifier window can be enlarged to take up more space on the computer screen.

Hint: Occasionally a window will open behind the Magnifier. If you cannot access the Title bar of the window because it is behind the Magnifier, you will either need to resize the Magnifier window or close the Magnifier entirely.

To Move the Magnifier

The Magnifier window can be anchored on any side of the computer screen or can float anywhere on the computer screen.

1. Move the mouse pointer to the middle of the Magnifier window. The mouse pointer changes to a hand with a pointing finger.

2. Click and drag to move the Magnifier.

  • To float the window: Release the mouse button anywhere in the middle of the computer screen.
  • To anchor the window: Drag the window until the magnifier expands and attaches to another side of the computer screen.

To Modify the Magnification Level

When the Magnifier opens the level is set at 2, but can be increased to 9. 1 is normal sized text.

1. Click the Magnifier Settings button on the Taskbar.

2. Make desired changes to the settings.

Clicking the Close button will close the Magnifier Settings dialog box and the Magnifier.

If you accidentally close the Magnifier, you can open it again by double-clicking the Magnifier icon on the Desktop.

Click the upward and downward pointing arrows to change the magnification level.

The Colors options are similar to what you can select in the Display Properties.

3. Click the Minimize button to hide the Magnifier Settings dialog box.

Using the Narrator

The Narrator reads text displayed on the screen aloud. Because this is not a full featured program, like some screen readers, it has limited capabilities. For instance, even though it cannot read text in Microsoft Word, it can read characters as they are typed. It reads aloud the text on most dialog boxes and can read words aloud that are copied into Notepad or WordPad.

To Explore Narrator Options

1. Click Start > Programs > Accessories > Accessibility > Narrator. The Narrator opens.

2. Double-click the Microsoft Word icon on the desktop.

3. Type The Narrator only reads individual letters as they are typed in Microsoft Word, but will read whole words in Notepad or WordPad. If you type slowly, you will be able to hear each letter read aloud.

4. Press Ctrl + A to select all of the text in the Microsoft Word document.

5. Press Ctrl + C to copy the selected text.

6. Click Start > Programs > Accessories > Notepad. Notepad opens.

7. Click Edit and select Paste.

8. Press Ctrl + Shift + Spacebar. The Narrator begins reading the contents of the Notepad window.

9. Click the Close button on the Notepad window. Wait until the dialog box has been read by the narrator, then click No to discard changes.

10. Click the Close button on the Microsoft Word window. Click No to discard changes.

11. Click Exit on the Narrator dialog box to close the Narrator.

Hint: To use the Narrator to read Web pages, copy the text from Internet Explorer into Notepad.

Changing the Display Options

If there is not enough contrast on the computer screen with the default settings in Bigprint or if you want to use a light background with dark text, you can change the color settings to a preset color scheme or create your own color scheme.

To Select Color Schemes

1. Double-click the Display icon on the Desktop. The Display options window opens.

2. Click the downward-pointing arrow next to the Scheme drop-down list. A list of predefined schemes appears.

Hint: If you want to quickly return to the display settings that are set for the Bigprint profile without logging off, click the Save As button next to the Scheme drop-down box. Name the scheme Bigprint. After applying a new scheme, you can select and apply the Bigprint scheme listed in the scheme list to return to the original settings. The scheme is deleted when you log off.

3. Select a scheme, such as High Contrast White (large). Schemes containing the words large, extra-large, and/or high contrast were developed for persons with vision difficulties.

4. Click OK. The changes are applied and the Display dialog box closes.

To Change the Text Size

There are eight items that have a font size associated with them. If you do not want to use the Magnifier to enlarge text on the computer screen, you can modify any of these settings to enlarge the text displayed on the computer screen.

1. Double-click the Display icon on the desktop.

Hint: If you created a Bigprint scheme in the color schemes exercise, and want the display to appear as it does when you log onto Bigprint, select that scheme before making any changes to the text size.

2. Click the downward-pointing arrow next to Item and select Active Title Bar.

3. Click the downward-pointing arrow next to Size and select 16. This increases the font size to 16 pt.

4. Click Apply. The text size on the title bar changes to reflect the new size.

The following table lists the items that you can change the font size for along with the default settings and a description of what the items modify.

Keyboard Options

There are a number of alternatives and alterations you can make to the keyboard to improve accessibility on the Gates Library Computer.

Access the settings for the keyboard options by double-clicking the Access Options icon on the desktop.

StickyKeys

Keys that normally need to be pressed together, can be pressed individually in sequence. For instance, if you want to copy a selected area of text in Word, you could press Ctrl, release it, and then press C to complete the action.

StickyKeys are on when you log on to Bigprint.

FilterKeys

When FilterKeys are on, extra, repeated letters will not appear on the screen.

Using the On-Screen Keyboard

The On-Screen Keyboard is useful for persons who are not able to use the keyboard or who want to use the mouse to type. You can even set the On-Screen Keyboard to hover mode, which enables a person to just move the mouse pointer to a character on the On-Screen Keyboard to select it.

To Use the Hover Mode

For persons who are unable to click a mouse, the On-Screen keyboard can be set to accept input by just hovering the mouse pointer over a character on the On-Screen keyboard.
