Observation of Robots with Different Expressions on Education Application Towards Entrainment Robots

The purpose of this paper is to observe whether if robot expressions are affecting subjects’ stress and physiological status during the exam. This project proposed two kinds of robot expressions in this experiment, robots express themselves differently when subjects answer correctly or incorrectly. Subject heart rate and brainwaves are monitored by sensors during the experiment. The experiment discovered when subjects face hard questions and answered incorrectly, there are different fluctuations in subject stress which in turn is shown by robotic expressions. This proves that robot expressions influence subject stress under different circumstances which in turn can be applied as a feedback mechanism for influencing stress with students, in the future may substitute humans as teachers.
