CMAC: Collaborative multi agent computing for multi perspective multi screen immersive e-learning system

Traditional e-Learning systems like Vidyo, Skype, Hangouts, A-View etc. do not ensure proper gaze alignment among the remote participants. Our research has shown that a gaze aligned multi-perspective multi-screen e-Learning system provides much better immersive experience. To provide multiple perspectives of the participants, we are using 5 cameras at each participant location, each one separated by 45 degrees, covering a range of 180 degrees, so that the system can choose appropriate perspective to present to the remote participants based on set of rules. We realized that a single standard computer is not able to capture and stream more than 2 HD video streams reliably, so we had to design a flexible multi-agent system to distribute the video streaming across 3 computers at each classroom. In this paper we present the architecture of our Smart classroom system, CMAC.
