7 September 2000 UA Guidelines Teleconference Present: Jon Gunderson (Chair) Ian Jacobs (Scribe) Denis Anson Mickey Quenzer Eric Hansen Harvey Bingham Dick Brown Tim Lacy Gregory Rosmaita David Poehlman Absent: Jim Allan Regrets: Rich Schwerdtfeger Kitch Barnicle Charles McCathieNevile Next meeting: 14 September Minutes of previous meeting: http://lists.w3.org/Archives/Public/w3c-wai-ua/2000JulSep/0341.html JG: Who would be available for additional teleconfs 12th and 19th (1:30pm - 2:30 ET). Yes: DB, TL (12th), MQ, EH, JG, IJ, HB, GR No: DA Agenda: http://lists.w3.org/Archives/Public/w3c-wai-ua/2000JulSep/0352.html 1.Issue 297: Style vs. content and background sounds http://server.rehab.uiuc.edu/ua-issues/issues-linear.html#297 Proposed resolution: http://lists.w3.org/Archives/Public/w3c-wai-ua/2000JulSep/0343.html /* IJ reviews proposal */ IJ: I don't think that notification is required here (for non-rendered content) since the user has configured the user agent not to render some content. MQ: I want indication, though, that this particular page has content that I'm not hearing. IJ: So change the proposal from "don't play" to "don't play without explicit user request." DA: I am uncomfortable with the three-second parameter. E.g., I may have an online dictionary and need words pronounced at a slower rate.e JG: Is length a big deal to you, Tim? TL: We won't look at how long the sound is. We'll give complete control of all sounds. I don't see the utility of the extra logic. GR: Media players should be able to compute the length of a clip. IJ: There's an issue of user interface: it may be annoying to get a media player for very short information. By the time a media player appears, the sound is over. IJ: Does anybody feel strongly about keeping the "3 seconds" part? EH: I think that for short sounds, you might not want the full-blown media player. MQ: If you have a short media clip, you don't want the player. IJ: I would note a possible error in the proposal, there's no P1 requirement to stop non-style sound. EH: I'm in favor of a lower priority for repair functions. We should spend less time on repair and more time on WCAG conformance. RESOLVED: - For audio, video, animation control funtionalities, distinguish P1 for content that's not style and P2 for content that's style. DA: As for automatic rendering, I think people should be able to play on demand. IJ: It's a new requirement to say "For sounds specified by the author to play automatically, don't play them automatically but allow the user play them manually. DA: We are trying to help people with cognitive disabilities and also people who are using sound output. IJ: Note that we don't have a requirement for turning images on individually after a global configuration to not render them. IJ: We don't have a requirement that says "Whenever the user agent is configured to not render something, let the user know that something hasn't been rendered." How would such a requirement interact with checkpoint 2.1? IJ: How about a checkpoint that says "If the user agent recognizes but does not support, or is configured not to support some content, indicate this to the user." EH: What about style and decoration? Would that be a requirement as well (e.g., at a lower priority level). IJ: Suppose you turn off style sheets. Does the UA have to tell the user that there might be some generated content from the style sheet? IJ: I don't think individual placeholders are required for all content. For instance, for scripts and style sheets, I think global indication of presence suffices. For images, audio, etc., placeholders would be useful. Issues: a) Automatically rendering of audio, video, animations. ia) Don't play and don't notify? ib) Don't play and notify individually? ic) Don't play and notify globally? iia) Prompt before playing globally? iib) Prompt before playing individually? iiia) Don't play, notify, allow manual access globally? iiib) Don't play, notify, allow manual access individually? DA: All or nothing options are not accessible to many people. IJ: For the case of images, what's the P1 requirement to turn off globally, and then access one-by-one? DA: P1 for images - cognitive requirement to be able to turn off the bulk of images and then turn on piece-by-piece. b) Notification that some content is recognized but not processed or rendered. Proposed: - For checkpoints 3.1, 3.2, 3.3, 3.9, and applets. a) Don't render these content types automatically. b) Include a requirement for a configuration to notify the user that some content not rendered locally. c) Allow the user to render each element manually without having to change the configuration. IJ: I suspect we're going to merge G3 and G4 as the focus shifts from "global" to "automatic". - For checkpoint 3.5: a) Render as motionless image. b) Include a requirement for a configuration to notify the user that some content not rendered locally. c) Allow the user to view each animation without having to change the configuration. - For scripts, turn off and notify user that there globally. /* Back to the three seconds question */ IJ: User agents could allow fast forward of short content, but it doesn't help anyone. JG: But they won't want to make the distinction between three seconds and two hours unless they know that all their sound will be less than 3 seconds. DA: I think there's a different between alerts and other types of content. IJ: I think that the primary reason to include something like a three-second limit is to say to readers that we have considered this issue and that we know that it does *not* benefit users with disabilities to allow users to fast forward short sounds. Developers may or may not wish to allow control for things that are shorter than three seconds. GR: Allow configuration of time interval, with minimum of three seconds? IJ: Please note that the issue here is not about opening viewports or not; that's covered by 4.17. Action IJ: Repropose checkpoints for G3 and G4 related to audio, video, animation that takes into account: a) automatic rendering b) style v. non style c) three seconds. -- Ian Jacobs (jacobs@w3.org) http://www.w3.org/People/Jacobs Tel: +1 831 457-2842 Cell: +1 917 450-8783
