Abstract

We study the psychophysiological state of humans when exposed to robot groups of varying sizes. In our experiments, twenty-four participants are exposed sequentially to groups of robots made up of one, three, and twenty-four robots. We measure both objective physiological metrics (skin conductance level and heart rate), and subjective self-reported metrics (from a psychological questionnaire). These measures allow us to analyse the psychophysiological state (stress, anxiety, happiness) of our participants. Our results show that the number of robots to which a human is exposed has a significant impact on the psychophysiological state of the human, and that higher number robots provoke a stronger response.
