Hi All, I took a look at #10 and #34. I've included the original comment in its entirety followed by notes and a proposed resolution below. #10 Name: Jason White Email: jasonw@ariel.its.unimelb.edu.au Affiliation: none Document: W2 Item Number: (none selected) Part of Item: Comment Type: TE Comment (Including rationale for any proposed change): Guideline 1.2 does not require, at any conformance level, audio descriptions of live video; only prerecorded video is covered. Audio description of live video is possible, at least in some circumstances. It can indeed be accomplished at a high level of quality, as in live plays where describers have access to scripts in advance. In other situations, such a degree of quality and accuracy may not be attainable, but descriptions could still be attempted. Are there situations in which it would be technically and practically infeasible to provide audio descriptions of live video? If so, this item could be introduced at level 3, otherwise it is a candidate for level 2. Proposed Change: Add a success criterion at an appropriate level requiring audio descriptions of live video. Notes: Previous drafts (before 23 November 2005) included a similar criterion at level 3, "Audio descriptions of video are provided for live multimedia." A proposal to delete this success criterion was raised and discussed on 27 October 2005. RATIONALE: because it is almost impossible to do unless the live multimedia is scripted so you know when people are not talking so you can speak audio descriptions. In that case we are only talking about live plays or something and that was not seen as a major enough type of content on the Web for us to have a success criteria all about it. resolution: delete Guideline 1.2 L3 SC3 - audio descriptions (live multimedia) http://www.w3.org/2005/10/27-wai-wcag-minutes.html#item02 Proposed Action: Add a general advisory technique for Guideline 1.2 titled, "Providing audio description for live multimedia." Proposed Resolution: (accept_partial) A criterion similar to this proposal was included in previous drafts of WCAG 2.0. However, the working group decided to remove it since this is almost impossible to do unless the live multimedia is scripted. The working group did not feel that live scripted events were applicable to a wide enough range of web content to be included at the success criterion level, but plans to include advisory information about providing audio descriptions for live multimedia in the future. ------------------------------------------------------------------------- #34 Name: steven faulkner Email: steven.faulkner@nils.org.au Affiliation: Document: W2 Item Number: Success Criterion 1.4.1 Part of Item: Comment Type: TE Comment (Including rationale for any proposed change): The success criterion refers to "Text or diagrams". From the definiton of "text" in Appendix A:Glossary, it appears that images of text are not included. This can result in web authors using images of text (with a foreground/background luminosity ratio of less than 5:1) to circumvent this Success criterion Proposed Change: Include an explicit reference to the inclusion of images of text in terms of this success criterion. Notes: I don't think this interpretation reflects the intent of this success criterion, but can see the point given the definition of text we currently have. current definition of text: text sequence of characters Note: Characters are those included in the Unicode/ISO/IEC 106464 repertoire. Proposed Action: Update SC 1.4.1 and 1.4.3 to read: [current] 1.4.1 Text or diagrams, and their background, have a luminosity contrast ratio of at least 5:1. 1.4.3 Text or diagrams, and their background, have a luminosity contrast ratio of at least 10:1. [/current] [proposed] 1.4.1 Text, images of text, diagrams, and their background, have a luminosity contrast ratio of at least 5:1. 1.4.3 Text, images of text, diagrams, and their background, have a luminosity contrast ratio of at least 10:1. [/proposed] Proposed Resolution: (accept) Revise as proposed.
