The Active Braille as Braille Display

The Active Braille is supported by various screen output programs that include drivers for
the device, e. g.:



WINDOW EYES



JAWS



HAL (Dolphin Systems)



NVDA



VoiceOver



Blinux (SuSE LINUX)

If these programs are used, all of the Active Braille's functionality is assured.

7.1 Screen reader using Windows, Example Window-Eyes

Window-Eyes by GW Micro is one of the most commonly used screen readers worldwide.
It  enables  access  to  all  kinds  of  different  applications,  without  complicated  scripts.
Window-Eyes  is  highly  customizable,  so  you  can  control  how  to  display  the  monitor
information.

When you use Window-Eyes with a Braille display, you can track both the focus as well as
the mouse cursor. In addition, there is also an invisible cursor, the so-called WE-cursor. If
you  bind  the  Braille  display  to  the  WE-cursor,  you  can  move  the  position  of  the  Braille
display  relative  to  the  screen  without  changing  the  position  of  either  the  focus  or  the
mouse cursor.

7.1.1 Overview

Your Active Braille, just like all the other Handy Tech Braille displays, is supported by
Window-Eyes. The following table provides an overview of Window-Eyes commands that
can be entered with the control keys on the Braille display. We have not included an
exhaustive description of each of the functions, because they are already contained in the
Window-Eyes manual.
