Technologies are providing new opportunities for psychologists to record and study human behaviors in unprecedented detail. In time, such rich behavioral datasets will be collected by psychologists everywhere. We are studying the use of technologies to capture, measure, analyze and understand human social and communicative behaviors. However, the massive amount of video/audio/sensing data collected during multimodal interactions from hundreds of subjects can be difficult to explore for psychology researchers. We investigate how visual analytics can be of help in providing a new method for exploring such challenging datasets.
