Development of AR/VR Navigation System Using Non-Linguistic Information

This study aims to develop a navigation system for a wide range of people including foreigners who visit Japan and cannot understand Japanese at all. Though there are already a lot of navigation systems corresponding to many languages, it is impossible to further develop such systems in the same way as before. Therefore, this study demonstrates the originality to use non-linguistic information such as symbols, marks and pictograms, and to supports the tourist excursions by making it possible to collect, accumulate, share and utilize tourist spot information, using mixed AR/VR technologies. The usefulness of this system, especially when used outdoors, can be summarized in the following three points: 1) Reduction of constraints of time and space: Because the system can provide non-linguistic information with or without a recommendation request using AR technology, users can acquire appropriate information anytime, anywhere. 2) Realization of a dynamic real-time situation: By taking account of each user's situation and the information that becomes a topic on Twitter, the system can provide users with information relevant to each situation in real time. 3) Reduction of the burden of information acquisition: Because the system can provide information relevant to the situation at any time using mixed AR/VR technologies, the occasions for users to acquire information via terminals are reduced, enabling them to engage in efficient tourist activities.
