Virtual reality, or VR for short, is the representation and simultaneous perception of reality and its physical properties in a real-time computer-generated, interactive virtual environment. One possible requirement of VR is immersion. The user should be given the feeling that he or she is more in the fictional world than in the real world. To convey this impression, a VR headset is needed. To achieve a 3D effect, an image is displayed for each eye.
So far, the user of VR glasses is not fully integrated into the virtual world. This is because so far only the visual and acoustic signals have been decoupled and virtually replaced. However, the user can only achieve a fully immersive feeling if all of the human senses are influenced by virtually generated signals. Tactile gloves are already available that make the touch of a virtual object perceptible. In addition, there are clothes in the gaming industry that make the hits of a ball or similar tangible. It remains to be seen when the rest of the human senses will be substituted by virtually generated stimuli.
Forecasts clearly show that VR sales have increased strongly in recent years and will increase even more in the future (see Statistahttps://de.statista.com/statistik/daten/studie/318536/umfrage/prognose-zum-umsatz-mit-virtual-reality-weltweit/).
VR glasses: VR glasses are needed to get an impression of the virtual world. These can also consist of a smartphone with a suitable attachment and thus represent an inexpensive alternative.
Application: If your own content is to be presented virtually and you do not have enough know-how to create an app, external support should be sought.
Sound: To get one step closer to the real feeling of a virtual reality, a spatial sound effect can be created while using the technology.
Content: If own applications are to be created, content is necessary. With VR, this is usually in the form of 3D models.
