Psychological Evaluation of Frisky Robot Motion

摘要

This paper describes the emotional evaluation of a frisky robot that weaves around its human owner; the evaluation is based on the SD (Semantic Differential) method and the RRV(R-R wave variance) method using electrocardiograms (ECG) as the biosignal source. The SD method is effective to measure emotion, and the RRV method is suitable for investigating the physiological state from the heartbeat. The SD method shows that humans show a significant response only when the robot weaves, not when it simply shadows the human. Furthermore, we revealed that these methods are correlated which suggests that the RRV method supports real time evaluation.
