This document discusses the development of a virtual reality (VR) application for educational purposes. It begins by outlining the benefits of field visits for students but also notes the limitations of physical access. To address this, the document proposes a desktop VR application that can integrate different sources of information about the real world. It reviews literature on educational VR applications and design principles. The proposed application aims to link various types of information within a single screen to promote better learning compared to conventional materials. The document discusses evaluating the application for usability and learning effectiveness. Overall, the VR application is intended to provide students with an interactive virtual field visit experience while integrating multiple information sources for enhanced learning.
