Service robots, like delivery or telepresence robots, often act as proxies for people, though this representation is not always obvious to observers. For instance, when a delivery robot cuts in line at a grocery store, the identity of the person it represents matters. The lower social status often assigned to service robots (“it’s just a robot, it can wait”) can become problematic in human-robot conflicts, if the represented individual (e.g., senior citizen) is treated unfairly. Previous research indicates that people tend to overlook the human behind the robot, potentially disadvantaging the service recipient. This study aimed to determine whether people are more likely to grant priority to a delivery robot when informed about the person it represents. In a between-subjects virtual reality (VR) experiment the recipient was either made apparent with an avatar or not and participants had to choose if they would give priority to a delivery robot in a grocery store queue. Results showed that while the presence of the avatar increased participants’ self-reported consideration of the robot’s human recipient, it did not lead to higher compliance, as the willingness to grant priority was unexpectedly high in both conditions. The results suggest that social desirability and the novelty of human-robot interaction (HRI) may explain these outcomes and future research is discussed.

摘要

Service robots, like delivery or telepresence robots, often act as proxies for people, though this representation is not always obvious to observers. For instance, when a delivery robot cuts in line at a grocery store, the identity of the person it represents matters. The lower social status often assigned to service robots (“it’s just a robot, it can wait”) can become problematic in human-robot conflicts, if the represented individual (e.g., senior citizen) is treated unfairly. Previous research indicates that people tend to overlook the human behind the robot, potentially disadvantaging the service recipient. This study aimed to determine whether people are more likely to grant priority to a delivery robot when informed about the person it represents. In a between-subjects virtual reality (VR) experiment the recipient was either made apparent with an avatar or not and participants had to choose if they would give priority to a delivery robot in a grocery store queue. Results showed that while the presence of the avatar increased participants’ self-reported consideration of the robot’s human recipient, it did not lead to higher compliance, as the willingness to grant priority was unexpectedly high in both conditions. The results suggest that social desirability and the novelty of human-robot interaction (HRI) may explain these outcomes and future research is discussed.
