Abstract

Existing live tele-teaching systems enable eye-contact between interacting participants, however, they are often incomplete as they neglect finer levels of adherence to gaze such as gaze awareness and gaze following. A multilocation eLearning classroom setting often does not preserve relative neighborhood i.e., displays showing videos of remote participants at each location might not be congruent with their actual seating positions. This leads to incoherent gaze patterns during interactions. We present a media-rich distributed classroom architecture with multiple cameras and displays in each classroom. During interaction changes, cameras capturing appropriate perspectives of participants are streamed to displays in other classrooms. Hence for all interactions, the physical participants of a classroom are presented with appropriate perspectives of remote participants resembling gaze patterns during conventional-classroom interactions. We also present a framework to systematically analyze gaze patterns with its dependencies. The framework dictates optimal placement of media devices ensuring minimal deviation in capturing appropriate perspectives for a given set of resources. Evaluation results on a three classroom test-bed indicates a marked reduction in viewer cognitive load in discerning the entity-at-focus in an eLearning classroom environment.
