アブストラクト
The current study investigated the effect of a robot’s gaze direction while not engaged in any tasks (i.e., while “idle”) on users’ comfort and subjective impressions of the robot. We predicted that users would feel differently when the robot looked at the same objects as the user (i.e., during joint attention between robot and user) or not, even when the robot’s gaze direction was the same. We conducted an experiment in which participants watched a video clip five times in five different robot gaze direction conditions. To examine the effects of joint attention, participants were divided into two groups by the distance from the monitor on which the video was presented. Joint attention between the robot and participant occurred in different robot gaze directions between the two groups. We measured participants’ comfort, subjective impressions of the robot, and related variables. The results revealed that the robot’s gaze direction affected participants’ comfort and subjective impressions among participants 75 years old and above. However, we found no effect of joint attention. Additionally, participants felt most comfortable and had the most positive impressions of the robot when it looked at a monitor on which participants did not watch the video clip.
