There are a number of options for producing braille when only
having the use of one hand. A technology assessment is recommended to determine
the best option for the individual.
A set of extension keys can be obtained for the Perkins
Brailler that allows the operator to stretch their hand over the keys that
are required.
The Mountbatten brailler can be modified for a person with
the use of one hand either as a right hand user or a left hand user. One
student became very adept at using his Mountbatten brailler by pressing
the required keys serially before releasing to produce each braille cell.

Both the BrailleNote and Braille Lite (and possibly other
notetaking devices incorporating refreshable braille) can be used in one-handed
mode. Entry of braille is fairly slow, but speed develops with practise.
You can purchase a ‘unimanual brailler’ which
looks exactly the same as a regular brailler but has a very small switch
that allows the operator to individually hold down the required keys at
the one time and when released will produce the appropriate cell. This machine
recently cost A$1,700 Australian and is available from Howe Press.
