Half QWERTY One
Handed Keyboard
Who
are potential users?The Half QWERTY one handed keyboard is an excellent alternative for
individuals who require one handed access to a standard keyboard. Candidates are
individuals with hand or arm injuries, Carpal Tunnel Syndrome, RSI,
Hemiplegia or Deaf-Blind.
How does the Half QWERTY one handed keyboard work?
The Half-QWERTY typing technique is very similar to the standard two-handed
touch-typing technique. You place your hand where it would normally be if you were
touch-typing - that takes care of that half of the keyboard. To type the letters of the
other half, you hold down the space bar and do the same finger movement that would
normally be done by the other hand. Hitting the space bar alone still types a space.
Note that the relative finger movements used for one-handed typing are the same as those
used for two-handed typing. So, if you're already a touch-typist, you already know them.
You should be typing one-handed in a matter of minutes.
Use either hand
Note that Half-QWERTY works with either hand. It actually has two
virtual Half-QWERTY keyboards - one for each hand. This is done
automatically, without instruction from the user.
Sticky Keys
Sticky Keys is a feature that makes typing modifier-key sequences
(e.g., capital letters) easier for one-handed typists, in that you no
longer have to type the modifier (e.g.: Shift, Control, Alt) and the key
being modified simultaneously. You can type them in succession.
Depressing and releasing a modifier key once makes it active for the
next key typed. Pressing it twice locks it until it is unlocked by
pressing the modifier again.
How fast can I type?
With practice, Half-QWERTY typists can expect to reach speeds of
between 61% and 91% of those achievable by two-handed typists. Typing
speeds as high as 64 words-per-minute (wpm) have been recorded.
Can other people still use my
keyboard...?
Yes. The keyboard can still be used for two-handed typing. Half-QWERTY
doesn't interfere.
How fast can I learn it?
“... somehow your brain triggers the appropriate finger ... Within
15 minutes, I could type 20 wpm ...”
MACWORLD
If you've never learned to type before, learning Half-QWERTY will take
roughly the time it would take to learn standard two-handed touch-typing.
However, if you are a trained touch-typist, you can learn Half-QWERTY
in a matter of minutes, with little or no retraining.
Published empirical research has shown that (on average) a touch-typist
can learn Half-QWERTY in 1/3 the time it takes to learn a one-handed chord
keyboard. Half-QWERTY's innovative "skill transfer" design makes this
possible..
Ideal for One-Handedness, Hemiplegia,
Carpal Tunnel Syndrome and other hand-related injuries
Carpal Tunnel Syndrome and other typing-related injuries don't always
occur in both hands.
In cases where only one hand is affected, you can type with the other
hand, while the injured one heals. Half-QWERTY's innovative "skill
transfer" design makes the transition fast and easy.
Periodic rest breaks should be taken, so as not to risk injuring the
uninjured hand.
Deaf-Blind
Used in conjunction with a Braille display, Half-QWERTY allows
an individual who is deaf-blind to read what
they type as they are typing it.
