Emotional Influence of Pupillary Changes of Robots with Different Human-Likeness Levels on Human

This study explored the emotional influence of pupillary change (PC) of robots with different human-likeness levels on people. Images of the eye areas of five agents, including one human and four existing typical humanoid robots with varying human-likeness levels, were edited into five 27-s videos....

Summary:This study explored the emotional influence of pupillary change (PC) of robots with different human-likeness levels on people. Images of the eye areas of five agents, including one human and four existing typical humanoid robots with varying human-likeness levels, were edited into five 27-s videos. In the experimental group, we showed five videos with PC applied to the eyes of agents to 31 participants, and in the control group, five videos without PC were shown to another 31 participants. Afterward, the participants were asked to rate their feelings about the videos. The results showed that PC did not change people’s emotions towards agents independently. However, PC applied to the eyes of a robot representing an agent of no threat who may evoke empathy subconsciously enhanced people’s positive emotions, while PC applied to human images increased people’s negative emotions and reduced the feeling of familiarity.
