Virtual Reality Educational Tool for Lab Demonstration
Chemistry classes often comprise both in-classroom instruction and laboratory. Usually, these two components are separated for different time allocations and classrooms. Would it be possible to provide just-in-time laboratory demonstrations during lectures? Our group has developed a concept using 360 VR streaming to fit this need.
How It Works
A teaching assistant (TA) is equipped with a VR camera attached to a camera vest to perform an experiment in the lab. The camera captures experimental details in real-time and then broadcasts via a server to the instructor and students outside the laboratory.
The TA is connected with the instructor through a voice line. The students watch the streaming of the chemistry experiment with VR goggles (or with the web browser of their computer, if VR goggles are not available). The TA, the instructor, and the students interact around the experiment's content as the demonstration proceeds.
The pace of the experiment is mediated by the instructor with real-time feedback from the students. The VR streaming provides an immersive watching experience for the students, and the learning is strengthened by discussions at each step with the instructor and TA.
This VR education tool is ideal for laboratory course demonstration, including in conditions that need social distancing (e.g., during COVID pandemic).
The VR360 camera (Ricoh Theta Z1) can directly stream to internet streaming server (YouTube). YouTube allows broadcasting to many students. The downside is that such implementation has a ~5 second delay time in streaming.
