Internet2 Rich Presence
Rich Presence trials are participatory, distributed, and experimental. Participants download and install a specially tuned integrated communications client on their laptops. This client allows participants to initiate voice, instant messaging, and video calls to each other using the receiver's email address as a single, converged electronic identity.
Communication is enhanced through the inclusion of rich presence services, through which participants may see not only who is on-line, but also where they are and what they are doing. As participants connect to the wireless LAN, their location and calendar presence is updated automatically. Room location is derived through triangulation of 802.11 signals and is cross-referenced with the meeting calendar to learn the name and duration of the session in that room at that time.
