Accessibility for Java-based visualizers

Accessibility features help users who have a physical disability, such as restricted mobility or limited vision, to use software products successfully.

The visualizer is a Java™ JFC (Swing) application. If you want to use JAWS as screen reader on Windows, the Java Access Bridge is required. The default Java runtime environments (JREs) that are used for the visualizer is in the following directory:

<installation>\Commons\jre

Copy the following files to the directory jre\lib\ext:

jaccess-1_4.jar for Java platform edition 1.5.x
access-bridge.jar

If you use a special JRE, copy the files above to the directory jre\lib\ext and add the following line to the file accessibility.properties that is located in the directory jre\lib.

assistive_technologies=com.sun.java.accessibility.AccessBridge

For more information about the Java Access bridge, visit Java SE Desktop Accessibility.

imvisualizer97.exe -J-Dgui.optimization=ScreenReader

The file imvisualizer97.exe is in the following directory:

<installation>\im\IMVisualization\bin
