Collage of Video and Sound for Raising the Awareness of Situated Conversations

This paper describes our attempt to build a communicative medium for capturing and re-experiencing conversations situated in the real space. We first show a system that captures and interprets conversation scenes by ubiquitous sensors. Based on the system, we present three approaches to visualise and facilitate users to access the extracted conversation scenes, i.e., chronological summarisation of videos, spatio-temporal collage of videos, and ambient sound display
