How visually impaired people enter
data into a computer
If we choose to, most people could learn the layout of a
'querty' keyboard, and type a document without any problems -
including visually impaired people. However, we all usually like to
check the keyboard every now and then, especially to find those
characters we don't use very often! So how do visually impaired
people manage in situations like this? Read on to find out about
the various specialist devices available for people with less
sight....
 These are keyboards of standard size, with
the usual size keys. However, they have a bigger and bolder
typeface so the keys are easier to see. No special software is
required. Also available are Large Print Keyboard Sticker Label
Kits, which are simply added to your existing keyboard.
Good colour contrast is essential, with the usual combinations
being white text on a black keyboard or black text on an ivory
keyboard. yellow text on a black background, or visa versa is
another alternative.
Combination Braille & Large Print Sticker Label Kits or
Braille and Large Print keyboards are also available
 In the same way as Large Print keyboards, these
keyboards are of standard size, with the usual size keys. The
tactile Braille characters are embossed on each key, so pressing
any key on the Braille keyboard produces the text shown in print on
that key, just like a standard keyboard. No special software is
required.
A cheaper alternatively would be to purchase a Braille Keyboard
Sticker Label Kit. These are usually clear so the original keys
show through. Combination Braille and Large Print Sticker Label
Kits or Braille and Large Print keyboards are also available.
3. Dictation software
This Software allows the user to dictate text directly into an
application such as Microsoft Word or Outlook using just their
voice, therefore getting rid of the need to type into a keyboard
altogether. An example is Dragon Naturally Speaking Professional.
Over time the software learns the way you speak and subsequently
recognises what you say.
Another feature of most of this software is the ability to
control computer functions using your voice, from opening folders
to copying and pasting or simply accessing the start menu or
opening and closing your programs. It allows a great deal of
flexibility.
4. Screen readers or synthesizers
As discussed in our July newsletter, people with little vision
can use a screen reader to access on-screen computer information.
The user can therefore use a standard keyboard to enter data, and
the screen reader will read out what they type. The screen reader
can be set to read out each letter as it is entered, or each word,
or simply to read out the whole sentence when it is finished.
Examples of this software are Jaws, HAL and LookOUT.
We hope this information helps you appreciate the range of data
input aids available to visually impaired people. Please see

keyboards and stickers sets, and other access products.
