RE: Animation conveying information

I agree with Ricky. And, depending on how it is implemented, it may not be
perceivable in WHCM for example .

Ms J,

 

Since it's relying solely on a change of size to convey information, I'd
suggest 1.3.3 Sensory Characteristics applies. 

 

Cheers,

 

Ricky

Hi all

 

Thank you for replying. For clarity, I have already noted the nonconformance
for pause, stop, hide. However, I don't feel this is sufficient alone (in
response to the my direct email replies) because even if they provide a
mechanism so that it can be paused, say, that still doesn't solve the
problem that there is no alternative for screen reader users.

 

Colour isn't used as a means of conveying any information so use of colour
doesn't come into it.

 

The animation is simply the button transitioning smoothly between a small
and big size so it prompts users to interact with it by 'pulsing' - I guess
something similar visually would be the way apple programmes you have open
on a mac jump up and down at you from the bottom ribbon to tell you you have
a notification. 

 

So my question really is when I suggest it needs an alternative for screen
reader users, what SC would I align it with? 

 

I could consider motion a state and therefore fail it for 1.3.1 and 4.1.2 as
you suggest Steve. But then I have a follow up question. So I also have
other animated content on the website. So there is an image of a pointing
finger which moves to indicate what to click. This image has no text
alternative. Would you then fail it for 1.1.1 and 1.3.1 and 4.1.2? I feel
like that makes sense, but I believe 4.1.2 only applies to user interface
controls not images? So then I couldn't fail all animated content in the
same way for the same...  it leads to the problem where motion is a state
for a UI control, but not for an image?

 

Does the fact it's animated make it time based media? It's position is
dependent on time so it feels like time based media? Like video only
content? I'm thinking of 1.2.1, but appreciate it doesn't really feel like
it fits.

 

Thanks

 

Sarah

It may be a non-conformance of SC 1.4.1: Use of Color if the change of
colour does not have a contrast ratio of at least 3:1.

 

Also, if the button changes from not pulsing to pulsing it would be
indicating a change of state, so the information would need to be conveyed
programmatically as per SC 1.3.1 and 4.1.2.

 

It may also be a non-conformance of SC 2.3.1: Three Flashes or Below
Threshold and/or SC 2.2.2: Pause, Stop, Hide.

Subject: Animation conveying information

 

Hello

 

This is maybe niche and something I haven't seen before. I have a website
which uses animation to convey information. For example, to show that you
must click a button next, the button pulses. This is information conveyed by
movement. It isn't really time based media and it isn't really non-text
content... it is animation/movement used to convey instruction. 

 

What SC would you align this with please? It is almost sensory
characteristics but the instruction is implicit in the animation....

 

It needs an alternative for people who can't perceive the animation, would
this be 1.1.1? Or 1.2.1?

 

Thanks

 

Sarah
