Setting up virtual reality and augmented reality learning environment in Unity

We propose a framework and a setup for presenting complex models for curriculum contents in both augmented reality and virtual reality environment. After constructing some three-dimensional models representing real world objects such as trees, stones, rivers, dams, and buildings, our workflow uses the Unity engine in combination with Virtual Reality headset devices to create interactive applications for both Virtual Reality and Augmented Reality environments to support students understanding the curriculum contents through their surrounding. Typical challenges are addressed when creating 3D curriculum contents, integrating these models into Unity and solutions are proposed where possible. The overall structure of the project is described with some functionalities added to Unity for visualization and interaction with the models.
