- Media space for distributed groups to participate
and interact in webcast events, such as lectures.
- Two HCII 2007 presentations on current research
designed to enhance capabilities of ePresence.
Presentations: Wed 4:00, "e-Learning & m-Learning", Exhibition Hall 2-A
· Baecker, Birnholtz, et al. (2007)
Smooth intergration of videoconferencing within architecture to allow “video- conferencing for the few” to exist concurrently with “webcasting to the many.” · Baecker, Fono, Blume, Collins, Couto (2007)
How a persistent chat system enables viewers of a webcast to engage in dialogue about the content of the learning event, during and after the event.

The Web Portal continuedViewing Presentations
- Viewers can embed presentations into their website or blog.
Web portal embeds hosted presentations into portal interface.
- When a user gives “praise” to a presentation, it is automatically
added to a list of the user’s favourite presentations.
- Through this, users are easily able to “bookmark” content for
future reference.
ePresence Conferencing
