Peripheral Feedback on Participation Level to Support Meetings and Lectures

In the EU-funded Integrated Project “Computers in the Human Interaction Loop” (CHIL), perceptive technologies are developed that enable us to build systems that, through perceiving and interpreting the ongoing course of events, are able to support people in situations of co-located communication and collaboration. In the current paper, we present two services. In one service, participants in a small-group meeting receive real-time feedback about observable properties of the meeting that are directly related to the social dynamics, such as individual amount of speaking time or eye gaze patterns. In the other service, teachers in a lecture room receive real-time feedback about the activities and attention level of participants in the lecture. We describe the usercentered design process, the conceptual designs and preliminary results of evaluations.
