Checking the accessibility and usability of a document in the blind tab

An HTML document can be opened with aDesigner to determine how accessible and usable the page is to readers who rely on voice browsers to read webpages.

To check the accessibility and usability of a document for people who are blind:

1. Open the document in one of the following ways:
   • Click File > Open, and then navigate to URL or the local file to be checked.
   • Type the URL in the address line, and then click GO.
     The document opens in the Browser View pane.
2. Click Blind above the top right pane to select the blind mode.
3. Open the Blind Usability Visualization preference page in one of the following ways:
   • Click Settings.
   • Click Window > Preferences > ACTF > Blind Usability Visualization. Set the visualization mode that aDesigner should use, and click either Apply or OK.
4. Visualize the blind usability and detect the accessibility and usability problems in one of the following ways:
   • Click the Visualize button.
   • Click the Visualization menu > Visualize (blind) or use the shortcut key (Ctrl+Shift+B).
5. Click ID/CSS to see the relevant information in the tabs.
6. (Optional) Click Save to save the report file as an HTML document.
   Note: The report file is an HTML document consisting of three parts: a diagram showing the overall rating, a usability visualization view, and a problem list. When you click a line in the problem list, its corresponding element in the visualization view is highlighted, and the page automatically scrolls if necessary to show the element.
7. Address each entry in the problem list. See Line View pane (blind usability) for details. As each problem is successfully resolved, the rating in the Overall Rating pane improves.
