Comment:

Hello,
We are currently completing the translation of Understanding WCAG 2.0 based on changes made in the October 14, 2010 version.
One part of the work of our group is to translate the titles of the new Flash techniques.
In our opinion, the title of technique Flash34 is too restrictive as it only talks about screen reader detection.
However, in the technique itself, note 3, it stands that "Other assistive technology tools, including screen magnifiers, or tools not used as assistive technologies may also utilize MSAA in ways that result
in Accessibility.active being set to true.
".
As the property accessibility:active does not only concern screen readers, we suggest that "screen readers" be replaced by "assistive technologies", to prevent from confusing the reader who may think that this technique is only related to screen readers.

Proposed Change:
Using assistive technology detection to turn off sounds that play automatically

WG Notes:

Resolution: We agree, and have changed the title of the technique. Change the title of FLASH34 to: Turning off sounds that play automatically when an assistive technology is detected

(Please make sure the resolution is adapted for public consumption)
