                      One-handed Keyboard Software Demo   
                  -----------------------------------------

                              (...continued...)


The demo of the one-handed keyboard now continues with examples on how to
use the program, followed by further description and ordering information.
Feel free to try out these examples as you read them.

Example 1: Pressing "f" with the left hand produces "f" . BUT, HOLDING DOWN
THE SPACEBAR AS YOU PRESS "f" with the left hand produces "j" .


Example 2: To type the word "grow" with the left hand, you would press the
following keys (N.B. "Space-g" means while holding down the spacebar to press
the letter "g"):

Keys you press on the keyboard:      g      r      Space-w   w

Characters you see on screen:        g      r         o      w


Example 3: To type the word "hello." you would press the following keys:

Keyboard:       Space-g  e  Space-s  Space-s  Space-w  Space-x

Screen:           h      e     l        l        o        .



Note also the following special combinations:

Space-Tab = Backspace

Shift-Space = Enter


Feel free to start typing at any time with either one or both hands!

Notice that you have the choice of using either your left hand alone, or your
right hand alone, or both hands. The software actually creates two virtual
Half-QWERTY keyboards - one under each hand! Both sides are remapped in a
mirror image when the spacebar is depressed. This means that you can change
typing hands on the fly, without having to alert Half-QWERTY of your
intentions - an added bonus for those with repetitive strain injuries.

Sticky keys (also called "key latching") allow for one-fingered use of
modifier keys - the shift and control keys, for example. Depressing and
releasing one of these keys once makes it active for the next key. Depressing
it twice locks that key until it is unlocked by depressing it again. This
feature is built into Half-QWERTY. The feature is off by default but can be
turned on/off at any time by pressing Ctrl-Alt-x.

Note that you still use the space bar to type a space. Merely depress and
release the space bar within an interval of 1/4 second, and a space will
appear on the screen.

Half-QWERTY is very unobtrusive software. Its hardware requirements are few
and modest. Its effects on normal keyboard operations are barely noticeable
to anyone except those who benefit from its presence. This is an advantage
because it means that abled and disabled users can share the same computers
without the expense of customized hardware. Half-QWERTY brings computers
one step closer to being universally accessible.

Half-QWERTY has a wide scope of potential users, ranging from people with hand-
related physical disabilities to those with visual impairments. Used in
conjunction with a Braille screen, blind and visually impaired people can
read what they type as they are typing it, much as a seeing person does.

The utility also has an audience among the general public. Writers,
secretaries, and other frequent users will benefit from being able to operate
the keyboard and mouse concurrently. For example, when editing text, a user
can now scroll through a document with the mouse in one hand, while correcting
errors using the keyboard in the other hand. Similar gains can be achieved by
accountants, who no longer have to remove their hand from the number pad
to type words.

The package includes a set of keyboard labels. Half-QWERTY is available for
DOS and Macintosh computers. A price list is attached.
