The following item from 255 should be considered for 508 or 508/255 joint.
S 1193.51 (*)(c) Compatibility of controls with prosthetics. Touchscreen and
touch-operated controls shall be operable without requiring body contact or
close body proximity.
It is not covered by the other provisions.
508 does require alternatives for people who are blind but people with
prosthetics should not have to use a blind mode of operation.
Should we require that touchscreens work with prosthetic hands, hooks,
headsticks, hand dowls (used by people with spinal cord injuries) etc?
Or do we think that they should use some other special approach - or the
"audio with step through using physical controls" that would be used by
someone who is blind?
Touchscreens are becoming much more popular. Small ones mostly will work
with a stylus or pen and would work. But some touch screen are sensitive
only to the touch of human body parts. (e.g. capacitive screens).
I THINK this is a 'hardware" group issue but am posting to 'General" as well
in case it is not.
Hardware, is this your issue?
