Sales Talk of a Robot at a Flanking Position Gives Positive Impressions to a Human Customer

There are many researches that devise the appearance of agents that recommend products, but there are not many researches that focus on the environment in which a robot and a person interact. In this research, we examined whether there are differences in the impression on the robot and the change in the degree of interest in the product under the face-to-face condition and the 90° condition when the robot explains the product. As a result, there was no significant difference in the degree of interest in the products between the two conditions, but in the evaluation of the impression on the robot, it was found that the 90° condition was more likely to be felt as 'obedient" and "humorous" significantly. Therefore, it was found that although the 90° condition gives a better impression on the robot than the face-to-face condition, it does not affect the degree of interest in the product explained by the robot.
