Three types of media will be given special focus: audio/video streaming, interactive 3D environments, and elastic media such as chat messages or discussion boards. To achieve the transfer of such media, we will design best-effort protocols for real-time audio/video conferencing/broadcasting, timely-reliable protocols for interactive 3D environments, and reliable data exchange protocols for elastic media. Current communication technology such as e-mail does not support interpersonal relationship in distributed collaborative environments. We intend to design a novel communication tool with the interpersonal relationship in mind. Participant will be able to send other users video/audios and other multimedia document in the context of routine daily activities, such as “I miss you” and “I love you” clips. The recipient views the multimedia content (video clips) either synchronously or asynchronously, depending on the context and environment. Asynchronous communication techniques are needed if, e.g., the time zone is very different so that a participant sends a good morning clip to another participant and this clip will be used as a wake up alarm. The proposed ambient intelligent tool will be designed to enhance relationship between distributed friends/co-workers and family members in a subtle and appropriate way.
