Demonstration of ObserVAR: Visualization System for Observing Virtual Reality Users using Augmented Reality

Abstract

Virtual Reality (VR) has been used increasingly as a part of VR classroom in which students can explore outside the classroom experiences inside the classroom. However, the instructor is unaware of the students' activities and engagement inside the virtual experiences, because the instructor cannot observe a large group of students inside the VR classroom. Thus, it hinders interactions between the instructor and students. To solve this challenge, we present a visualization method that allows the instructor to observe VR users (i.e., students) at scale using Augmented Reality. Specifically, the virtual environment and students' gazes are visualized for the instructor and optimized to reduce visual clutter, so the instructor has overall awareness of the entire VR classroom.
