In the last years, museums around the world began using museum guide robots as an alternative to audio guides. Thus, it is important to identify how these new museum guides can optimally interact with visitors and whether they are more efficient that conventional audio guides. In this paper, we present the results from an experimental study which compared conventional audio guides with robots with different ‘personality’. These results demonstrate that people remember significantly more information when they are guided by a cheerful robot than when their guide is a serious one or a conventional audio system. Importantly, we also introduce the idea of two collaborative tour guide robots. This idea was inspired by cognitive studies showing that people remember more when they receive information from two different human speakers. Interestingly, our participants also liked more our collaborative robots, than any version of a single robot and/or audio system. GRAPHICAL ABSTRACT

博物馆机器人指南还是传统的音频指南？一项实验研究

在过去的几年里，世界各地的博物馆开始使用博物馆导览机器人作为语音导览的替代品。因此，重要的是要确定这些新的博物馆指南如何与游客进行最佳互动，以及它们是否比传统的音频指南更有效。在本文中，我们展示了一项实验研究的结果，该研究将传统音频指南与具有不同“个性”的机器人进行了比较。这些结果表明，当人们被一个欢快的机器人引导时，与他们的引导是严肃的或传统的音频系统时相比，他们记住的信息要多得多。重要的是，我们还介绍了两个协作导游机器人的想法。这个想法受到认知研究的启发，该研究表明，当人们从两个不同的人类说话者那里接收信息时，他们会记住更多。有趣的是，我们的参与者也更喜欢我们的协作机器人，而不是单个机器人和/或音频系统的任何版本。图形概要
