RE: [a11y-metadata-project] accessHazard

Hi all,

 

I am concerned that the term "flashing" can be misleading or confusing.
Something that flashes is not bad in itself, everything depends on the ratio
of flashes per second. At least not for everyone. While something that
flashes to any ratio can be annoying and even disabling for a person with
attention deficit is not for everyone. And for something that flashes
generate a seizure, certain conditions must be met.

I think we need to be more precise.

Perhaps there could be a general indicator for something that flashes and
another for something that can generate seizures in some people.

Yes! Even better.

Charles McN had a great idea when he brought this up.  But it may actually
be a bit simpler to specify. 

Rather than sav

 

*	noFlashing
*	noMotionSimulation
*	noSound

in addition to the three properties we have today

*	flashing
*	motionSimulation
*	sound

 

we might just want to have a state of "none" (saying that you checked and
that there are no hazards that you are aware of).

 

That would change the spec to

*	flashing
*	motionSimulation
*	sound
*	none (or noHazard)

which makes it cleaner.  I think that saying the negative to each of the
three properties would be a bit tedious.  And, of course, not having the
property means that it has not been checked.

Chuck has updated the issues list to include the discussion of whether
accessHazard should state positive or negative information. See that post
and my comments, which are also below, at:

d_-_Ok_as_is.2C_or_should_it_be_negated_in_sense.3F]

I believe we need both accessHazard=flashing and accessHazard=noFlashing,
etc.. This is because there are three cases we'd like to distinguish:

1. checked and it's fine
2. checked and it is NOT fine
3. didn't check

"Didn't check" can be signified by no metadata -- this will be most of the
content on the Web. In cases where someone has checked, let's record both
positive and negative states.
