comment #12 clarification

Hi David

 

In your comments your #12 was

 

12. The role of blinking and flashing content is confused -

http://www.w3.org/TR/WCAG20/complete.html#time-limits-blink   and

http://www.w3.org/TR/UNDERSTANDING-WCAG20/#seizure-does-not-violate-terms 

 

 We do not understand what you mean.

 

Blinking is a distraction problem.   Content that blinks can cause problems
for some users.  If it stops within 3 seconds - it only provides a delay not
a barrier.   And the blinking can be a useful tool for all users including
people with cognitive disabilities or low vision to draw their attention to
something important.   Blinking at slower than 4 per second is not as
seizure problem.

 

Flashing on the otherhand refers to flashes that are more than 3 per second.
This is a seizure problem even for a second. 

 

To keep these separate we refer to one as blinking and one as flashing.  (At
least we tried to)

 

>From your comment it sounds like you found a place where one of them is
crosslinked with a technique for the other.  Or perhaps you found something
else.   If you could clarify where you think we have these confused or used
the wrong term it would be most helpful.

 

Or does this answer your question? 

 

Thank you.
