Summary
This paper discusses the design, development, and evaluation of an augmented reality (AR)-based mobile application for a tour guide. The developed application is demonstrated by applying it to a UNESCO designated World Heritage Site, the Hwaseong Fortress in Suwon, South Korea, and evaluated using a survey instrument developed explicitly for mobile application evaluation. It is intended to provide a more immersive and interactive experience of the historical, cultural and architectural details of the heritage site using novel AR visualization methods.

Innovative VR tools and techniques
The application and development process provided in this article are significant in that they not only demonstrate the possibility of applying state-of-the-art technology, but also incorporate user requirements for usability and other aspects that tourism applications should have.

VR in education
The operation flow of the application consists of three main functions: navigation to points of interest, information visualization with AR technology, and interactive learning activities with AR-based serious games.
