Tablet system for sensing and visualizing statistical profiles of multi-party conversation

In this paper, we present a tablet system that measures and visualizes who speaks to whom, who looks to whom, and their cumulative time in face-to-face multi-party conversation. The system measures where each participant is and when he/she speaks by using the front and back cameras and microphone of tablets. The evaluation result suggests that the system can measure such information with good accuracy. Our study aims to support the motivation of participants and enhance communication.
