Hello:
The questions posed by Curtis are hard ones to answer. The use of keyboards
other controls is diminishing because moving parts are expensive, subject to
vandalism and not very flexible. Some kiosks that I have seen have the controls
in the same place. The function of the controls change depending on the menu
currently on the screen. Some screens have the ability to activate different
areas of the screen at different times. For keys that don't move around, a tactile
symbol could be put next to the key. As for how to activate the system, why not
a telephone handset. I have seen museum displays that use this method to play
examples for patrons. There could be a set of buttons next to the handset that
could be used to control the system. I am thinking of something that would
look like a pay phone. The phone companies have figured out to make rugged
pay phones. This technology should be of use. I would have the system start
an introductory message a few seconds after the handset was lifted. The message
would tell the blind user how to use the keypad to control special functions.
one function I would include would be a "HELP" button. This could dial a preset
number to contact a real person. One advantage of having a HELP button would be
that it would also provide a means of notifying maintenance workers if repairs
were needed. More later.
