With the VR glasses you can change all "screens" in the training room in size or position or spatial position.
Usually not required, but you can.
In VR glasses, you can also define the contents of each individual screen (or image). The content can be any video or image.
Most important, however, is the quality control in VR.
You can immediately attend the training you have just defined yourself and run it at multiple speeds.
Thus, if defined, you have seen all the time-dependent components themselves and only needed a fraction of the time.
