I would like to specifically express concern about Proposal 2 below. I have
no idea what "an equivalent means" is or how it would be interpreted.
Specifically, I can't think of a means that affords the privacy that is
provided by direct use of controls. For example, if the equivalent means is
speech, then you have to be in an environment where it is appropriate to
talk to the device. That's not appropriate for a public device "I'd like to
withdraw $500 from my account" or a private device like a music player where
voice input might be difficult. I don't know what other equivalency there
would be. I believe the controls should be accessible in themselves as
currently exists in the standard. To eliminate the requirement for
specifically accessible mechanical controls means you would create a device
that requires a person who is blind to be able to do speech input.

Subject: [teitac-hardware] Touch-based contols language
>From call today. Initiating conversation regarding proposed language
options to address touch controls:
Proposal 1 - If a product utilizes touch screens or touch-operated controls,
an input method shall be provided that complies with Mechanical Controls
Section.
Proposal 2 - If a product utilizes touch screens or touch-operated controls,
an equivalent means of input/interaction/control shall be provided.
Please comment and discuss.
Thanks,
Rob
