Hi all, In today's media subgroup meeting we had a request to add some explicit text about the need for AT control of autoplay functionality on media elements to our requirements documents. This came up because it was unclear to people that the introduction of an @autoplay attribute is actually a good thing for accessibility, because it exposes this functionality in markup and thus to UAs and AT, while leaving it to script would not provide for AT needs. We have thus decided to add this requirement to the requirements document. I've added the following text to the system requirements section 4.1: * '''(KA-6)''' Autoplay on media elements is a particularly difficult issue to manage for vision-impaired users, since the mouse allows other users to an auto-playing element on a page with a single interaction. Therefore, autoplay state needs to be exposed to the platform-level accessibility framework. The vision-impaired user must be able to stop autoplay either generally on all media elements through a setting, or for particular pages through a single keyboard user interaction. NOTE: This could be enabled through encouraging publishers to us @autoplay, encouraging UAs to implement accessibility settings that allow to turn off all autoplay, and encouraging AT to implement a shortcut key to stop all autoplay on a Web page. Feel free to edit http://www.w3.org/WAI/PF/HTML/wiki/Media_Accessibility_User_Requirements#Access_to_interactive_controls_.2F_menus to adapt the wording. Cheers, Silvia.
