As more robots are exposed and utilized in human society, defining the usage context and the function of the robot is becoming difficult. Therefore, the importance of designing the effective Human-Robot Interaction increases. Generally, gaze control is considered as effective and essential communication tool not only in human relationships but also in robot-including relationships.
Through the literature review and the platform test of the target robot used in the experiment, it was found out that gaze is an effective interaction modality that can be utilized with less limitations.
The major goal of this study is to verify the effect of robot’s gaze on user’s likability and attention level toward the robot. Four different types of gaze behavior were applied to a robot platform situated in the environment which has little information about the function or the purpose of it.
The experiment showed that consistent direct gaze was positively correlated with the user’s high likability level toward the robot. Another finding was that mixture of direct gazed and aversion had positive correlation to the user’s attention level toward the robot.
This study clarified that the appropriate gaze control can create more likable, or attention brining robot which arouse user’s interest to get closer to and spend more time with it.
