Re: ARIA Live and values that updates very quickly

There may be three groups of items in users mind.
1) Important to let me know immediately so I can react quickly (Assertive)
2) Interested, but not what i'm focusing on (Polite)
3) I don't want to hear this (Off)

You can consider the following
Step 1: Allow users to read the page first time (no live region announcement by default)
Step 2: Everytime user focus on the element, user can choose to assign the element to assertive, polite or off)
Step 3: For all assertive element, changes will be announced immediately (combine the label, values and action). Shortkey to commit the action is read out so user can react immediately)
Step 4: For all polite element, it can be announced between longer intervals, say ever 5 mins
Step 4 (alternative): Instead of offering assertive, users can press short key to read elements assigned to assertive list.

My 2 pence

Regards,
Caleb
