Unlike
people with normal sight, people who are visually impaired do
not have the option of choosing between the hunt-and-peck and
the touch keyboarding typing styles. The visually impaired person
either keys by touch or not at all.
The TACTUS keyboard has been found very useful for computer
users who are visually impaired. This is due to the ridges on
the keys. The ridges provide twenty feedback points in lieu
of the two feedback points on the letters F and J of the standard
QWERTY keyboard. The ridges are very easy to feel and are organised
in a logical way, that is, into two geometrical figures that
can be easily understood and remembered. Moreover, relocating
the hand to the home row is made much simpler because of the
ridges.
Touch keyboarding teachers, working with students who are visually
impaired, report that the TACTUS Keyboard greatly simplifies
the task of teaching these people the location of the keys.
The TACTUS Keyboard has been tested by several organisations
for the visually impaired and found to be very effective in
training visually impaired users to touch-type. |
