Abstract
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.
