VR is Educational
The key differential feature of VR, in relation to a flat screen 3D production, is that your view is in true 3D space. Imagine a completely 360 degree panoramic viewable space in which you are also able move about and interact within. You would be actually standing inside the coal mine set not just viewing it. Look over your shoulder.
Virtual Reality offers a new way of education. It allows you to stand inside the picture and become immersed in a real sense of what it was like.
