Configure JAWS Screen Reader for Unified Service Desk

JAWS (Job Access With Speech) is a computer screen reader program for Microsoft Windows that allows blind and visually impaired users to read the screen either with a text-to-speech output or by a refreshable Braille display.

Unified Service Desk supports JAWS version 18 for Windows screen reader for speech output in the Unified Service Desk client. All the Unified Service Desk controls and custom controls that are part of the Web Client package are JAWS compliant. For the custom controls that you develop as part of the solution package, you need to define the necessary properties to make the controls JAWS compliant.

JAWS support for focusable controls (Interactive controls)

You can configure JAWS screen reader support for controls that are focusable (Interactive controls), such as buttons, list box, menu, radio button, and check box.

For JAWS screen reader to read a focusable control, you must specify a value for the AutomationProperties.Name Attached Property.

For example:

<Button Width="30" Height="30" Name="Save" ToolTip="Click to save the doc." AutomationProperties.Name="Save" Focusable="True" IsTabStop="True">

JAWS support for tooltip

By default, JAWS screen reader does not support reading toolbar button tooltip text. However, you can create JAWS custom scripts to enable JAWS screen reader to read tooltip text.

Here is a sample script for checking button name and tooltip text (help text). In Unified Service Desk, if you do not configure the tooltip text explicitly, the system applies the button name to the tooltip text. In such case, JAWS read both the button name and the tooltip text. To avoid reading the button name and tooltip text, you can create a custom script to check whether the button name and tooltip text is same.

In the sample script, if the help text is not the same as button name, JAWS screen reader reads the tooltip (help text).

include "hjConst.jsh"
void function SayObjectTypeAndText(int nLevel)
SayObjectTypeAndText(nLevel)
if nLevel == 0
   var string sHelp = GetObjectHelp()
   var string objName = GetObjectName()
   if sHelp && sHelp != objName // If help text is not equal to the object name, the JAWS screen reads the help text
      Say(sHelp,ot_help)
   endIf
endIf
EndFunction

In the example image, the button name and the tooltip text is same: REMINDER. In this scenario, the script checks for the button name and tooltip text, which is different and hence, JAWS does not read the tooltip text.

In the example image, the REMINDER button name is different than the tooltip text: SET REMINDER. In this scenario, the JAWS screen reads the tooltip text.

You can write script for your application in JAWS. For more information about writing scripts, see Basics of Scripting Manual.

After you write the script, name the file as per the product name (example: UnifiedServiceDesk.jss). These are called application script file, and must be saved in either the JAWS shared or user settings folder in order to be loaded with the application at run-time. More information: JAWS Scripts and Script Files.

JAWS support for non-focusable controls (Non-Interactive controls)

By design of the product, the tab position does not focus the non-focusable controls (Non-interactive controls). Hence, JAWS screen reader does not read controls that are non-focusable, such as text block, image, and labels.

Workaround

One of the ways to enable JAWS screen reader to read the non-focusable controls is to wrap the non-focusable control using the UserControl element, which enables the JAWS to read the non-focusable controls.

When JAWS reader lands on the first focusable control, reads the non-focusable controls and then reads the focusable controls.

The XAML example for Session Overview control displays you the UserControl wrapping of the grid.
