As an emerging technology, virtual reality (VR) has been used increasingly as a learning tool to explore “outside the classroom experiences” inside the classroom. While VR provides an immersive experience to the students, it is difficult for the instructor to monitor the students' activities in the VR. Thus, it hinders interactions between the instructor and students. To solve this challenge, we investigated a technique that allows the instructor to observe VR users at scale using Augmented Reality. Augmented Reality techniques are used to visualize the gazes of the VR users in the virtual environment, and improve the instructor's awareness.
