“…To improve upon this, the authors developed a chair system in the previous papers [5], [9], [10], called ambient sensing chair, that uses only four pressure sensors, discretely positioned at the bottom of the seat of the chair. These chairs sense the center of pressure of a seated user without constraint and wirelessly transmit data to a server via Bluetooth.…”

The authors aim to develop a community detection system without constraining users. This paper introduces a method to detect communities in which users are engaging in a conversation with each other, by an ambient sensing of body sways and their synchrony between users. We apply an improved ambient sensing chair, which had been developed in our previous study. The system employs wireless force sensors to measure the center of pressure. By using measured speaker/listener information and synchrony between any users' body sways, it is confirmed to detect the community information in experiment.

SUMMARYMore and more recent studies of emotion estimation have taken the approach of ambient sensing, where users are monitored without constraining their bodies and without being aware of the sensing system. Few of them, however, focus on audience emotions. We attempted to examine audience emotions, which are difficult to estimate when using only individual data, and which come to be estimated more easily when using ambient sensing of synchrony among multiple users. We developed an ambient sensing chair, which employs wireless sensors to determine the center of force of the seated user, and designed an experiment for an audience watching a soccer game on TV or a technical presentation in order to examine the relationship between audience body sway and emotional states in a natural situation. We found that synchrony could be well correlated with audience excitement and boredom, something not observable in the individual data. These results indicate the possibility of development of service marketing systems that evaluate TV content, and feedback systems that give notice of the emotional state of an audience to a presenter.

In this paper we use ubiquitous smart-chairs to evaluate live presentations. We validate the hypothesis that the audiences' activities can be recognized with pressure sensors under chairs' legs (74.6% accuracy rate from 8 typical activities in 8 live presentations, each with 6 chairs seated), and certain activities (e.g. talk, take notes) are linked to the audiences' subjective attitudes and evaluation of the presentation, moreover, the combinations of interactive activities like Talk-Take Note, Nod-Laugh and Take Note-Laugh are well linked to a positive rating of the presentation.
