Ah in looking is see part of the problem for thinking 1.2 and 1.3 were the same in 1.2 it says "When text equivalents of visual information are spoken aloud (either by a human or a speech synthesizer) and synchronized with the multimedia presentation they are called "auditory descriptions." Refer to checkpoint 1.3. " This is inaccurate. 1.2 is only about text. So it should read "When text equivalents of visual information are provided they must be synchronized with the multimedia presentation. ( NOTE: Checkpoint 1.3 requires that audio descriptions also be provided until text descriptions can be read by screen readers (or equiv) in synchrony with the visual track.) Having posted the last two memos -- I would like to invite people to find a way to combine these two if we can -- since it would be nice to do so. But 1.3 is so specialized it may be hard. Give it a whirl though. thanks Gregg -- ------------------------------ Gregg C Vanderheiden Ph.D. Professor - Human Factors Dept of Ind. Engr. - U of Wis.

That is -- an audio description (until the text equiv could be read by screen readers - in which case it would automatically fulfill this requirement). By combining these two -- we now require that the text version be synchronized but we do not require an audio version exist (though if you did one you would need to synchronize it). In effect we would remove audio descriptions for movies from the guidelines. Now one could say that the criteria would add that back in. But I don’t think we can have criteria for a point require something that is not covered by the point itself. We tried to fit 1.3 into 1.2 in the first place and were unable. That is how we ended up with it as a separate item. It still needs be separate unless we can figure out at way to specifically require this in the checkpoint -- which the current (revised) 1.2 does not Gregg -- ------------------------------ Gregg C Vanderheiden Ph.D. Professor - Human Factors Dept of Ind.
