Comments added, prefaced by AS: Proposal #5 Accept John Slatin's rewording of the Note that appears in the Benefits [2]: Note: Time-dependent presentations requiring people to use a single sense to follow two or more things at the same time may present significant barriers to some users. Depending on the nature of the of presentation, it may be possible to avoid scenarios where, for example, a deaf user would be required to watch an action on the screen and read the captions at the same time. However, this would not be achievable for live broadcasts (e.g. a football game). Where possible, provide content so that it does not require tracking multiple simultaneous events with the same sense, or give the user the ability to effectively control different media signals independently. GV: suggest we change last sentence to end. "or give the user the ability to freeze the video so that captions can be read without missing the video." It is not necessary to make this general. Information is not presented auditorally simultaneously. It is a visual problem only. (Simultaneous tactile???) Allowing independent control of media streams raises synchronization questions. AS: Suggest removing this as a success criteria. It is a very specific case that is best handled in techniques, not as a success criteria, even at level 3.
