Virtual Reality (VR)

When we talk about Virtual Reality, we follow Philippe Fuchs’ idea that Virtual Reality is made of two main elements: immersion and interaction that lead to a feeling of presence in a virtual world. Whether we use a Virtual Reality headset or not is not important. This is why even games like Minecraft belong to the realm of Virtual Reality. (Philippe Fuchs: Le traité de la Réalité Virtuelle).

According to Metzger C. & Schulmeister R. (2004), interaction can come in various forms.
