The purpose of this study is to propose a theoretical framework for a digital twin-based smart science tourism system using augmented reality in Gwanghwamun Square. To date, smart tourism service was not sufficiently developed for the provision of relevant tourism information to visitors as tourism contents were managed by the separated information system of each institution. The tourists could not receive ideal tourism routes based on their preferences and also according to congestion of each institution. Moreover, the business model using existing tourism services was not well developed, and thus the current tourism services have not sufficiently contributed to the revitalization of the regional economy. We designed a digital twin-based tourism content management system that provides integrated management of tourism information, and augmented reality (AR) science tour services which are included with contents recommendation, best path finding, contents sharing and gamification. We also adopted a business model using the AR tourism platform based on digital twin technology which could contribute to the invigoration of the local economy.

This study proposed a mobile virtual reality-based application for on-site risk management using Historical Building Information Modeling (HBIM) to alleviate the inefficiency of paper-based risk management of architectural heritage. In this research, we focused on the design of the metadata and the database structure that is based on the point of interest (PoI), anchor, and content metadata for advanced context-aware information retrieval from HBIM system in the mobile environment. To verify our method, we created a mobile VR-based application of the Gwandeokjeong building in Korea. After, we conducted a comparative experiment on performance time, task load and usability and proved the efficiency of our method for on-site risk management. In conclusion, our metadata and database structure in this study contribute to suggest a method to interoperate between HBIM system and mobile VR system and conduct advanced context-aware information retrieval.
