More and more recent studies about emotion estimation have taken an ambient sensing approach, where users are monitored without constraining their bodies and consciousness of sensing systems. Few of them, however, are intended to audience emotions. The authors aimed to examine that audience emotions, which is difficult to be estimated by using only individual data, become to be estimated more easily by the ambient sensing of synchrony of multiple users. We developed the ambient sensing chair, which employs wireless sensors to determine the center of force of seated users, and designed an experiment on the audience watching soccer game on TV or technical presentation to examine the relationship between audience body sways and their emotions in a natural situation. As a result, synchrony could be well correlated to their excitation and boredom, which were not observed from individual data. These results indicate the possibility of the development of service marketing systems that evaluate TV contents and feedback systems that give notice of audience emotions to the presenter.
