Religion was the first virtual reality game

Immerse yourself in completely new worlds at the push of a button - what sounded like science fiction a short time ago is reality today. The new virtual reality glasses generate enormous media coverage, because the virtually represented “worlds look so real that you immediately forget where you are actually sitting. You can look around, the glasses adjust the picture, and the sound moves with it in the room. Only the feelings remain as strong as ever. ”[1] In the school sector, teachers and students quickly ask the question to what extent the new VR glasses can be used advantageously in terms of media education, and what are their limits - or even their dangers .

The most important advantage of the new VR systems is the extremely high degree of their "immersion". This means the impression of immersing yourself in a completely new world (and thus largely forgetting your real environment). This effect is difficult to describe in words for those who are inexperienced in VR - anyone who wears VR glasses immediately understands what immersion means.

The VR systems that have recently become available all use a "head-mounted display" (HMD for short), ie a display attached to the head. The display, usually attached to the head similar to ski goggles, shows the wearer's two eyes a slightly shifted perspective, creating a three-dimensionally correct environment for the viewer - even if he moves his head, because the VR system calculates the data from motion sensors out all movements in milliseconds. The perceived environment remains stable - immersion is created.

Some VR systems are also supplemented with tracking sensors that can determine the head position in the room - as well as hand controllers so that the viewer can not only observe his virtual environment, but also actively interact with it.
