A simulated experience known as virtual reality (VR) can be quite similar to or very dissimilar from the actual world. Virtual reality has potential uses in entertainment (such as video games) and education (i.e. medical or military training). Augmented reality and mixed reality are two additional, different subsets of VR-style technologies.
To provide lifelike visuals, sounds, and other sensations that mimic a user’s physical presence in a virtual world, current standard virtual reality systems either use virtual reality headsets or multi-projected environments. A user can see around the virtual world, move around in it, and interact with virtual features or objects while utilising virtual reality technology. The impression can also be produced by specially built rooms with numerous large screens, although it is most frequently produced by VR headsets that have a head-mounted display with a small screen in front of the eyes. Virtual reality normally includes audio and visual feedback, but haptic technology may also enable additional types of sensory and force feedback.
