20:06:03 <RRSAgent> logging to https://www.w3.org/2021/01/26-immersive-web-irc
20:06:56 <ada> ahh Zakim is already here
20:08:02 <leonard> scribe Leonard
20:08:47 <ada> https://github.com/immersive-web/layers/issues/239
20:09:17 <leonard> Ada: WebXR screen readers mentioned by Dylan
20:09:51 <leonard> Dylan: Only seen prototypes. A little work on Accessibility object model by Microsoft with audio clues.
20:10:05 <ada> https://github.com/immersive-web/webxr/issues/1158
20:10:15 <leonard> ... difficulty is identifying important items for audio priority
20:10:41 <leonard> Ada: How to access screen readers from WebXR. Touchy when there are no release screen readers.
20:11:33 <leonard> Dylan: "Last of Us, Part 2". Sound icons to alert player to what is in the environment
20:11:57 <leonard> Ada: Asks Dylan to note that in issue #239
20:12:30 <leonard> ... Back to issue specifics. Get system level titles to display for video content
20:13:08 <cabanier> q+
20:13:18 <leonard> ... Video layers point to a video element. Uses first source that is playable. Discards subtitles.
20:13:31 <ada> ack cabanier
20:13:47 <leonard> Rik: Resource that is played is similar to what is played on a regular HTML page
20:14:18 <leonard> ... Subtitles are still present, but uncertain where the titles are displayed
20:14:43 <leonard> Ada: Will follow up with tests and examples.
20:15:07 <leonard> ... Probably expect same behavior video layer.
20:16:17 <leonard> Rik: User/developer may not want default behavior
20:16:45 <bajones> This MDN page has some details on captions with on HTML5 players: https://developer.mozilla.org/en-US/docs/Web/Guide/Audio_and_video_delivery/Adding_captions_and_subtitles_to_HTML5_video
20:16:51 <leonard> Dylan: Immersive captions W3C group (Chris Hughes) has been putting together a prototype player. Currently uses 360
20:17:06 <leonard> ... video with different configurations.
20:17:46 <bajones> q+
20:17:53 <leonard> Ada: Perhaps a new layer type that would display raw text on top of everything.
20:17:55 <ada> ack bajones
20:18:42 <leonard> Brandon: Wants a way to easily do this. Is not concerned about the issue of styling text, including HTML elements.
20:19:09 <leonard> Ada: Goal is to solve accessibility issue in WebXR without needing to wait for DOM-layer solution.
20:19:28 <Dylan_Fox_XR_Access> Dylan_Fox_XR_Access has joined #immersive-web
20:20:25 <Dylan_Fox_XR_Access> present+
20:20:35 <leonard> Brandon: Feels that there is a need and desire for a simple light-weight library that displays text
20:21:31 <leonard> ... pretty sure that it is possible to get basic default titles
20:23:25 <leonard> Ada: Pretty sure there will be standards for subtitle styles. Just need to support that.
20:24:32 <ada> q?
20:25:23 <leonard> Ada: To Rik or Brandon -- interested in seeing this develop or is this a dead-end?
20:26:25 <leonard> Brandon: Would like to see it going. References MDN article about subtitles (linked above).
20:27:33 <leonard> ... A lot depends on what the browser supplies vs. what needs to be provided by the developer
20:27:44 <Dylan_Fox_XR_Access> q+
20:28:26 <leonard> Ada: Don't be worse than the regular web. Notes that the HTML video element is not accessible
20:28:26 <ada> ack Dylan_Fox_XR_Access
20:29:11 <leonard> Dylan: State of art for captions is to allow setting size & contrast. When expanded into Immerisve environments
20:30:49 <leonard> ... would include motion and positioning of those captions. Should be synch with W3C Immersive Captions WG.
20:30:54 <cabanier> q+
20:31:04 <ada> ack cabanier
20:31:24 <leonard> Rik: Is it more important that the captions are available to accessible technologies?
20:32:05 <leonard> Ada: Discussion has been on accessibility for hard-of-hearing
20:32:57 <leonard> Brandon: So much depends on the particular disability.
20:33:25 <leonard> Ada: May have to deal with the difficult issues of people who have difficulty with vision and hearing.
20:34:22 <leonard> Dylan: Usual solution is to provide a transcript that can be read with Braile readers (or some other h/w that supports the user)
20:34:44 <leonard> q+
20:35:24 <ada> ack leonard
20:36:48 <leonard> Leonard: Some video conference providers have real-time transcription capabilities. Zoom allows a person as a transcriber
20:36:59 <leonard> ... and are prototyping automated systems
20:37:24 <leonard> Rik: If platform provides subtitles, would that work?
20:37:40 <leonard> Ada: That would be the best solution.
20:38:16 <leonard> Brandon: Might need opt in/out capability to support specialized needs or requirements.
20:39:37 <yonet_> q+
20:39:50 <ada> ack yonet_
20:39:51 <leonard> Rik: Will look into system support for accessibility
20:40:28 <leonard> Aysegul: Android & iOS has system settings. Can be used on a page-by-page basis
20:40:58 <ada> q?
20:41:16 <leonard> #237: https://github.com/immersive-web/layers/issues/237
20:41:59 <RafaelCintron> q+
20:42:17 <leonard> Rik: Feature allows setting multiple mip levels on the composition layer.
20:43:19 <leonard> ... Separate question for projection layers. All up to the UA.
20:43:25 <ada> ack RafaelCintron
20:43:27 <ada> q+
20:44:12 <leonard> Rafael: OK with options as long as there a means that allows the developer to determine multiple layers were not provided.
20:44:23 <leonard> Brandon: <breaking up too much to understand>
20:45:23 <leonard> Rafael: OpenXR has a separate run-time. On Windows there is a limitation the prevents sharing under certain circumstances.
20:47:03 <leonard> Brandon: Wondering if it is reasonable to allow the developer to request a number of mipmaps and the system reports back
20:47:13 <leonard> ... how many you actually got.
20:48:47 <leonard> Brandon: Several other means were discussed for handling the Windows limitations.
20:49:52 <ada> q?
20:49:55 <ada> ack ada
20:50:52 <leonard> Ada: Feature flag to allow extra-crisp text rendering. Is it possible to hint to browser that a certain image has overlayed text?
20:51:35 <leonard> Brandon: This flag allows filtering applied to text prior to creating image of text
20:51:52 <leonard> ... (that was a question with answer)
20:53:08 <laford> laford has joined #immersive-web
20:53:14 <laford> I heard OpenXR
20:53:35 <ada> q?
20:53:37 <laford> +q
20:53:46 <ada> ack laford
20:54:04 <leonard> Lachlan: Wondering about what extension
20:54:25 <RafaelCintron> q+
20:54:28 <leonard> Rik: No such extension.
20:54:42 <ada> ack RafaelCintron
20:54:59 <leonard> Rik: Will open new issue with discussion here
20:55:18 <leonard> Rafael: If want mips & anti-aliasing, what wins?
20:55:37 <leonard> Rik: No anti-aliasing currently available.
20:57:43 <leonard> Ada: Other business...
20:57:55 <leonard> ... Moving the WG meeting back to bi-weekly
