If you are new to accessibility, review "Understanding accessibility" before completing the checklist or contacting the Human Ability and Accessibility Center for help. |
|
Use this checklist for:
- general software products and applications that have a user interface
- software tools, this applies to both the user interface as well as the output of the tool
- Java 1.1.x applications that use standard AWT components and are designed to run only on Windows platforms
- software used by system administrators to control and monitor servers or other remote equipment
- Eclipse applications written with Standard Widget Toolkit (SWT) controls. Note: SWT controls do not use the Java Access Bridge.
- software with a command line interface
