We
think that it is
on a standard keyboard.
Touch-keyboarding (or touch-typing as the skill used
to be known) was reasonably difficult to learn at the
time of the manual typewriter. People learned touch-typing
because typing constituted a core competence required
in their occupation. They were for instance, secretaries
or writers. The great majority of typists, when the
typewriter was first introduced, used their typing skills
to transfer onto paper the words of others, as secretaries
and copyists do. Typewriters were also used by writers:
it is reported that Mark Twain wrote Tom Sawyer on the
just invented Remington typewriter.
The advent of the electric typewriter did not change
things much. Typing remained, in the main, a skill of
secretaries and writers. Therefore, from its commercialisation
in the late 1880s until the advent of the personal computer,
typing was a core competence of people whose working
time was mostly spent typing.
Things changed substantially with the advent of the
personal computer, in the mid-1980s. Suddenly, not only
did the keyboard have twice as many keys as the old
typewriter, but also the people who were using it were
not trained typists.
Today's Touch-typists Did Not
Learn the Skill on the Computer
Our research shows that most post-1980 computer users,
who can touch-keyboard, learned the skill on a typewriter.
We have found very few users who have become accomplished
touch-typists using a computer.
The motivation to learn to touch-keyboard exists. People
are aware of not using the keyboard properly and try
to learn. The number of touch-typing programs available
on the market is sufficient testimony.
Educators are aware of the importance of touch-keyboarding
and touch-keyboarding has been taught in schools from
the day the computers entered the classroom.
In spite of this, most computer users are not touch-keyboarders.
Why is this? We believe that the reasons are the following.
Why People Find it so Difficult
to Touch-Keyboard?
- Modern
computer application programs require the right hand
to move away from the keyboard very frequently (to
operate the mouse, for instance or the directional
arrow keys or other function keys). This means that
the hand has to be repositioned on the HOME keys many
times during a session and this task is not easy given
the subtlety of the markers on the reference keys
F and J. (More about why "form" should follow
"function").
- The
QWERTY layout makes it difficult to memorise the location
of the keys on the keyboard.
- The
keyboard has twice as many keys as the electric typewriter
and is difficult to use.
- Many
computer users today use the computer in the mode
of a "writer". That is, they compose the
material that they encode as for instance in the case
of a person writing and sending an e-mail message.
This mode allows the user the option of either looking
at the keyboard (hunt and peck typing) or looking
at the screen (touch-typing). Interestingly, the hunt
and peck option is not available to visually impaired
users who must be able to touch-type or cannot type
at all.
- The
majority of users use the computer to transfer information
from an outside source (e.g. paper, telephone) to
the computer. This is the case, for instance, of order
entry operators. Most of these users cannot touch-type
and the impact on productivity of this is enormous.
However, because employers are generally not aware
of the issue, there is no pressure on staff to learn
to use the keyboard properly and thus more efficiently.
(Employers are starting to realise the potential productivity
gains that could be achieved if computer users could
keyboard properly and tests to verify typing speed
and accuracy of job applicants are slowly being introduced.
Australia, for instance, has introduced a keyboarding
standard in 2001).
- Rapid
keying is a complex psychomotor process and mastering
it requires practice. Most computer users however,
do not spend enough time typing to practice and build
the skill. Whereas before, secretaries, who were generally
excellent touch-typists, spent most of their working
day typing, today, typing represents a small proportion
of the computer user's time. This does not allow the
skill to build and consolidate with practice.
- Curricula
of elementary schools have not yet caught up with
the fact that learning to touch-type requires frequent
practice just as learning to play a musical instrument.
Thus, most schools dedicate one hour per week to computer
classes and, of this time, a good part is spent in
activities other than keyboarding. Moreover, IT teachers
rarely can touch-type themselves and so are not aware
of the difficulty to become one. As a result, most
children leave school knowing "how to" touch-type
but without "being able" to touch-type.
Touch-keyboarding is Easy on a TACTUS Keyboard
The
TACTUS Keyboard has been designed with touch-keyboarding
in mind. The ridges on the TACTUS keyboard form two
boxes within which the fingers are obliged to move.
Each box is four keys wide, in order to accommodate
the four fingers which are used to tap the keys. Each
box has three rows so that each finger always moves
one row up and one row down from its position on the
home key. The picture below illustrates this point.

The ridges have two main functions:
- They
allow the hand to be re-positioned on the keyboard
very quickly after operating the mouse or the directional
keys.
- They
greatly facilitate touch-keyboarding due to the feedback
they provide. Instead of the just having the two markers
on the keys F and J, the fingers operate within a
clearly defined geometric frame which is easy to feel,
understand and remember.
