We developed an autonomous human-like guide robot for a science museum. Its identifies individuals, estimates the exhibits at which visitors are looking, and proactively approaches them to provide explanations with gaze autonomously, using our new approach called speak-and-retreat interaction. The robot also performs such relation-building behaviors as greeting visitors by their names and expressing a friendlier attitude to repeat visitors. We conducted a field study in a science museum at which our system basically operated autonomously and the visitors responded quite positively. First-time visitors on average interacted with the robot for about 9 min, and 94.74% expressed a desire to interact with it again in the future. Repeat visitors noticed its relation-building capability and perceived a closer relationship with it.

主动介绍展品的类人向导机器人

我们为科学博物馆开发了一种类似人类的自主引导机器人。它使用我们称为说话与撤退互动的新方法来识别个人，估计参观者正在看的展览品，并主动地主动向他们提供凝视的解释。机器人还执行建立关系的行为，例如以访客的名字向访客打招呼，并以友好的态度来重复访客。我们在一个科学博物馆进行了实地研究，我们的系统基本上在该博物馆自主运作，参观者的反应相当积极。首次访问者平均与机器人互动约9分钟，其中94.74％的人表示希望将来与机器人再次互动。重复访问者注意到其建立关系的能力，并意识到与其建立了更紧密的关系。
