Thanks for your support, your help is much appreciated.

We’ve been experimenting with an extension in Chromium, and Ningxin will be able to share some more details on that soonish. We plan to evolve the implementation in tandem with the specification, so interested people can also collaborate in code.

Good to hear. There are definitely many compelling use cases for both, and we’re eager to get your (and other group participants’) input. Feel free to propose new use cases and/or adjust the existing ones, if they do not capture (no pun intended) what you had in mind.

Out of the current UCs, the UC1 and UC4 deal explicitly with gesture recognition, and the UC1 and UC2 could be considered a type of a user interface for spatial information. That said, we should definitely add more use cases for these, especially if they unearth new requirements or have wider applicability.

Sounds like a very concrete and compelling use case to me, easily understood by anyone who has been using video conferencing :-) Filtering could be considered a special case of the UC3, but I think this would merit its own UC.

Cullen - would you like to draft some text for this to be added as an additional use case? Any extra requirements derived from this UC?

All - as Rob said, feel free to propose new use cases and requirements (mapped to the UCs) to be added to the above document. The wiki page is editable by all the group participants interested in contributing:
