Provide beacons for classroom sizes
Excerpt from my final thesis:
Currently the teacher can walk out of the seating plan. The coach can then not see where the teacher stands and in which direction he is looking. To solve this problem, the padding of the seating plan can be enlarged, but this brings up the problem, that depending on the classroom, the padding may be to high or to low. This solution is nothing one can rely on. Another solution is to extend the "bootstrap"-message sent by the VR-Classroom to also send position of "beacons", where one beacon is placed in a corner of the classroom and another beacon on the other side of the classroom. Using these two beacons the full size of the classroom can be calculated and the teacher can therefore not move out of the seating plan in the Coach-VR.
