| Summary: | This thesis deals with the design and testing of an experimental stenograph
keyboard for blind and sighted users. The new keyboard, called the
Minimum Chord Stenograph (MCS), is presented. It comprises two panels
of six keys, one for each hand. Relocation of the fingers above the keys
is at a minimum. A coding scheme for MCS was developed to allow ex
act phonemic description of the text or speech to be entered by alternate
hand typing.
Experiments were carried out with the MCS and with the standard
Stenograph-Boswell keyboards. The time between successive movements
of hands on the keyboards was precisely measured live with a 386 com
puter and the statistics have been compiled and analyzed. The results
show that the MCS’ performance (WPM) is significantly better than the stan
dard stenograph-Boswell; the problem of training time for the stenograph
seems to be solved at least at the level of initial competence. Extrapolating
from the published results for QWERTY, MCS has much better performance
than QWERTY at the initial stage. In conclusion, MCS keyboard may pro
vide an efficient alternative to the existing standard stenograph keyboard
and to the QWERTY keyboard. |
