(Sorry for the inconvenience)


The GNOME and KDE desktop environments included with PC-BSD provide accessibility features to assist users with vision and mobility impairments. This section provides an overview of these features and references to additional accessibility information.

NOTE: If you install GNOME or KDE-Accessibility using Package Manager, most of the applications installed with those components can also be started from the command line, regardless of which desktop a user is logged into.

GNOME Accessibility Tools

GNOME3 provides a "Universal Access" utility for configuring the desktop for accessibility. To open this utility, go to Applications → Settings → Universal Access. This will open the screen shown in Figure 9.10a.

Figure 9.10a: Universal Access Screen

The “Seeing” tab shown in this screen has options for assisting users with low vision.

The “Hearing” tab can be used to enable visual alerts, either to the window title of the current window or the entire screen. It provides a “Test flash” button for testing the settings.

The “Typing” tab, shown in Figure 9.10b, is used to enable features to assist users with mobility impairments.

Figure 9.10b: Keyboard and Key Options

More information about each of the options provided by Universal Access can be found here[1].

Orca Screen Reader

If you enable the “Screen Reader” in the “Seeing” tab, you can open the reader from Applications → Utilities → Orca Screen Reader. In the example shown in Figure 9.10c, the user has clicked the "Preferences" button.

KDE Accessibility Tools

To install the KDE accessibility tools, make sure that the "KDE-Accessibility" box is checked (it is by default) when selecting to install KDE either during installation or afterwards using Control Panel → Package Manager → Desktops.

The KDE-Accessibility component installs the following software:
Figure 9.10d: Configuring KMouseTool
  • espeak[2]: a speech synthesizer for English and other languages. DOES NOT WORK, NEEDS MORE TESTING
  • KMag[3]: a screen magnifier. In KDE, this application is in Applications → Utilities → Screen Magnifier or you can type kmag from the command line. Drag the magnifier window over the text you wish to magnify or click its "Settings" button to view the shortcuts for its various modes. Press F1 while the application is open to access the Kmagnifier Handbook.
  • KMouseTool[4]: clicks the mouse whenever the mouse cursor pauses briefly. It can also drag the mouse, although this takes a bit more practice. To start this utility in KDE, click Applications → Utilities → Automatic Mouse Click or type kmousetool from the command line. In the screen shown in Figure 9.10d, check the settings you wish to use, click the "Apply" button, then click the "Start" button. If you quit this screen, it will be added to the system tray and will continue to run until you launch its icon and click the "Stop" button. A PDF of the KMouseTool Handbook can be downloaded from the KDE site[5].
  • kmouth[6]: enables persons that cannot speak to speak through their computer. It keeps a history of spoken sentences from which the user can select to be re-spoken. To start this program, click Applications → Utilities → Speech Synthesizer Frontend or type kmouth from the command line. The first time you run this application, a configuration wizard will prompt you to set the command to use for speaking texts, the character encoding, and a language phrase book. DOES NOT WORK, NEEDS MORE TESTING

More information about KDE-Accessibility can be found in the KDE UserBase Wiki[8].
