| <H1 id="guiCheck">Checking the accessibility of an application in the GUI Accessibility mode</H1> |
| <P> |
| The GUI Accessibility mode can check the accessibility of any Windows® application running on the computer. |
| It can also check the accessibility of ActiveX controls embedded in a webpage, such as Flash ActiveX controls. |
| </P> |
| <P> |
| The following steps will check the accessibility of an application using the GUI Accessibility mode: |
| </P> |
| |
| <OL class="space"> |
| <LI>Switch to GUI Accessibility mode: |
| <OL> |
| <LI>Select the <B>File</B> > <B>Switch Modes...</B> menu to open the <B>Select a mode</B> dialog. |
| <LI>Select the <B>GUI Accessibility</B> mode, and click the <B>OK</B> button. |
| </OL> |
| <LI>Select a webpage or an application window to check its accessibility: |
| <BR>Select a target for checking by using the <B>Target Window</B> menu. |
| <UL> |
| <LI>Select an external browser window in the <B>External Browsers</B> submenu to check the accessibility of a webpage. |
| <LI>Select an external application window in the <B>External Windows</B> submenu to check the accessibility of a Windows® application. |
| </UL> |
| <LI>The accessibility check starts immediately, and may take a few moments to be completed. |
| <LI>Analyzing the results of the automated accessibility check: |
| <BR>The <B>GUI Report</B> view shows the accessibility problems. Please refer to <A href="#guiProblems">Problems reported in the GUI Accessibility mode</A>. |
| <UL> |
| <LI>To change the type of problems reported (Error, Warning, or Information), use the View menu(Ctrl+F10) to change the display settings. The results displayed will change immediately. |
| <LI>When a line of the report is selected, the area with the problem is highlighted on the screen, and the object icon in the GUI Outline view is also selected. |
| The cause of the problem can then be verified. |
| </UL> |
| <LI>Accessibility verification with manual inspection: |
| <BR>First, the contents of the <B>GUI Summary</B> view and the screen of the application can be compared to verify that the important information on the application screen is available as appropriate text information. |
| If the text information is missing or inappropriate, then using the application operation with a screen reader will be difficult. |
| <BR>Next, the order of the text shown in the GUI Summary view should be checked to make sure it is appropriate. |
| The order of the text in this view corresponds to the reading order with a screen reader. |
| <UL> |
| <LI>Use the <B>Refresh</B> function when the application screen changes due to scrolling or some other operation. |
| <LI>Set <B>Show Off-Screen Items</B> on to show off-screen object information. |
| <LI>If necessary, use the <B>Read Entire Text</B> function to check the listenability using synthetic speech. |
| <LI>If additional diagnostic support is necessary, please refer to the <B>GUI Outline</B> view or the <B>GUI Property</B> view to analyze the cause of problem. |
| </UL> |
| <LI>After fixing the accessibility problems the previous steps can be repeated to check the accessibility improvements. |
| </OL> |
| |
| <H2 id="guiProblems">Problems reported in the GUI Accessibility mode</H2> |
| <P> |
| The <B>GUI Report</B> view shows the accessibility problems found in the target application. The problems are categorized into Error, Warning, and Information. |
| The severity of each problem is uniquely defined based on how a blind person would use a screen reader. |
