Robots that are designed to work in close proximity to humans are required to move and act in a way that ensures social acceptance by their users. Hence, a robot's proximal behavior toward a human is a main concern, especially in human-robot interaction that relies on relatively close proximity. This study investigated how the distance and lateral offset of "Follow Me" robots influences how they are perceived by humans. To this end, a Follow Me robot was built and tested in a user study for a number of subjective variables. A total of 18 participants interacted with the robot, with the robot's lateral offset and distance varied in a within-subject design. After each interaction, participants were asked to rate the movement of the robot on the dimensions of comfort, expectancy conformity, human likeness, safety, trust, and unobtrusiveness. Results show that users generally prefer robot following distances in the social space, without a lateral offset. However, we found a main influence of affinity for technology, as those participants with a high affinity for technology preferred closer following distances than participants with low affinity for technology. The results of this study show the importance of user-adaptiveness in human-robot-interaction.
设计用于在人类附近工作的机器人需要以确保被用户社会接受的方式移动和行动。因此，机器人对人类的近距离行为是一个主要关注点，尤其是在依赖相对近距离的人机交互中。本研究调查了“跟随我”机器人的距离和横向偏移如何影响人类对它们的感知。为此，构建了一个“跟随我”机器人，并在一项用户研究中针对一些主观变量进行了测试。共有18名参与者与该机器人进行交互，机器人的横向偏移和距离在受试者内设计中有所变化。每次交互后，要求参与者在舒适度、预期一致性、类人性、安全性、信任度和不唐突性等维度上对机器人的移动进行评分。结果表明，用户通常更喜欢机器人在社交空间中的跟随距离，且无横向偏移。然而，我们发现了对技术的亲和力的主要影响，因为那些对技术亲和力高的参与者比技术亲和力低的参与者更喜欢更近的跟随距离。本研究结果表明了用户适应性在人机交互中的重要性。
