In this paper, we propose a dialogue-based navigation system for narrow areas (e.g., buildings, etc.). In particular, we develop Campus Navigation Partner System (CNPS), intended for the use by freshmen (first-year students) who are likely to get lost in the new environment on the university campus (with the campus of Kitami Institute of Technology set as the experimental environment). The CNPS operates on a smartphone and has the functions of facility navigation and indoor information presentation. Indoor environment navigation is typically a problematic task because GNSS (Global Navigation Satellite System) signals cannot be received with sufficient accuracy within concrete walls. Therefore, we utilized natural language dialogue as a navigation method that guides the users within the facility using navigation messages and images. To investigate the effectiveness of the constructed system, we conducted practical experiments with freshmen and senior students of the university and evaluated the performance of the navigation functionality. Moreover, we investigated the general impressions of the system which we evaluated separately with both freshmen and senior students to clarify the differences in evaluation viewpoints between freshmen and users experienced in the campus environment (graduate students, etc.).

在本文中，我们提出了一种用于狭窄区域（例如建筑物等）的基于对话的导航系统。特别是，我们开发了校园导航合作伙伴系统（CNPS），供在大学校园（北见理工学院的校园设置为新校园）的新环境中可能迷路的新生（一年级学生）使用。实验环境）。CNPS在智能手机上运行，​​并具有设施导航和室内信息显示的功能。室内环境导航通常是一个有问题的任务，因为无法在混凝土墙内以足够的精度接收GNSS（全球导航卫星系统）信号。因此，我们利用自然语言对话作为一种导航方法，使用导航消息和图像来指导设施内的用户。为了研究构建系统的有效性，我们与大学的新生和高年级学生进行了实际实验，并评估了导航功能的性能。此外，我们调查了系统的总体印象，该系统与新生和高年级学生分别进行了评估，以弄清新生与校园环境下的用户（研究生等）在评估观点上的差异。
