Defining an accessible user for the Web
To enable accessibility mode, user preferences must be set in the BMC Remedy AR System User Preference form. The following settings are available in the Accessibility tab of the User Preference form:
- Accessible Mode — Defines sight-impaired users' capabilities for a generated HTML page.
- Default — No optimization.
- Screen Magnifier/Low Vision — Accessed by Low Vision users with a third-party screen magnification device.
- Screen Reader/No Vision — Accessed by No Vision users with an assistive device, such as JAWS.
When adding image buttons to a form, you must add a label for the button image or alternative text so that screen readers can read the ALT tag for the image. When the No Vision option is set in user preferences, the screen reader uses the label text or alternative text.
- Accessible Message — Controls the amount of nonvisual feedback provided through active links. The following options are not used in the mid tier for version 6.3 and later.
- No Action — No messages are shown for accessibility. Active link message actions of the Accessible type are ignored.
- Message Action — Displays accessibility messages defined by an active link message action of the Accessible type.
- All Actions — Displays accessibility messages to reflect visual changes on the page, as well as accessibility messages defined by an active link message action of the Accessible type.
On the Web tab of the BMC Remedy AR System User Preference form:
- Session Timeout in Minutes — Specifies the number of minutes for the session to time out. If no value is defined, the default value defined in the BMC Remedy Mid Tier Configuration Tool is used. This value should be increased for No Vision users to provide them enough time to go through a form.
If no user preferences are set, no Section 508 enhancements are made to the form. Section 508 enhancements are added dynamically for each user when the HTML for the form is generated.
