I am making available to the HTML 5 WG the following user testing
footage of header/id combinations, @summary and @longdesc in use by a
blind power screen reader user. Each of the videos demonstrates these
methods/attributes in current use with commentary and discussion on
each. This footage should be useful for anyone interested in how these
features are really helpful for people with disabilities. The videos can
also be used as a point of reference in future discussion.   I am
presenting them to the group so they will hopefully find them
enlightening and act as a record of the usefulness of all of these
features. The tests are using JAWS 7 on Win XP SP2.

Each test has been divided into several clips and can also be downloaded
in its entirety, should you prefer, from the following directory [1].
However dividing the tests into clips makes the files smaller and the
issues/areas discussed easier to track. The clips are in Windows Media
.WMV format, and contain roughly the following content.

*HTML5 WG header/id test Video:Table 1 [20.5 Mbs]*
