For Users with Disabilities
Note
KPresenter is not usable by totally blind users. It is hoped that
a general screen reader for the blind will be available in future versions of KDE.
For low-sighted or light alergic users, several features are available from
->
.
Under
->
, you may select from several themes. If you are light alergic, the
HighContrastDark
or
HighContrastLight
themes
may be helpful. If you have difficulty reading small fonts or seeing small icons, the
HighContrastDark-Big
or
HighContrastLight-Big
themes will increase the size of text, buttons, and icons. You may also customize
background, colors, fonts, and icons from the same screen. A set of monochrome icons
is available.
Tip
If you choose one of the
Big
themes, you may discover that
some screens are too large to fit your monitor. Purchasing a larger monitor will be helpful.
You can drag the portions of the screen not visible into the visable area by
holding down the
Alt
key and dragging with the mouse anywhere
within the screen. If you have trouble operating a mouse, you can also move screens by pressing
Alt
+
F3
. In
the dropdown Windows Operations Menu, choose
.
Move the screen with the arrow keys and press
Esc
.
The
kdeaccessibility
module includes a screen magnifier
application called KMagnifier.
If it is installed, you may run it from
->
->
->
.
The
kdeaccessibility
module includes a Text-to-Speech
component called KTTS. If KTTS is installed, you can configure KPresenter to
speak the text that is under the mouse pointer or speak the text of each
screen widget as it receives focus. Before using this feature, first configure
KTTS. See The KTTS Handbook for details.
To turn on the TTS feature in KPresenter,
select
->
from the menubar.
This will display a dialog box.
Clicking
TTS
will allow you to change
the following.
-
Speak widget under mouse pointer
-
When checked, KPresenter will speak the text of each widget
as the mouse pointer moves over the widget.
-
Speak widget with focus
-
When checked, KPresenter will speak the text of each widget
as it receives focus.
-
Speak tool tips
-
When checked, KPresenter will speak the popup tool tip
for each widget in addition to the text of the widget.
-
Speak Whats This
-
When checked, KPresenter will speak the Whats This help
for each widget in addition to the text of the widget.
-
Say whether disabled
-
When checked, KPresenter will speak the word "disabled"
if the widget is currently disabled (grayed).
-
Speak accelerators
-
When checked, KPresenter will speak the accelerator
of the widget in addition to the text of the widget.
Accelerators are the underlined letters you see in the text of the
widget. For example, in the main menu, the
menu item
has the "Q" underlined. You can choose it by pressing
Q
.
To speak the accelerator, check this option and enter the
word you want to speak before the accelerator in the
Prefaced by the word
box. In this
example shown above, KPresenter will speak "Accelerator Q".
-
Polling interval
-
This option determines how often KPresenter will
check for a change in the widget under the mouse pointer or
a new focused widget. You should leave this option on the
default setting.
Note
If the
TTS
option does not appear
on this screen, you do not have the KTTS component installed
in your system.
Note
Not all widgets are spoken. For example,
the items on the main menubar are not spoken.
