VIRTUAL REALITY

Virtual reality is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings).

Standard virtual reality systems use either virtual reality headsets or multi- projected environments to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a head-mounted display with a small screen in front of the eyes, but can also be created through specially designed rooms with multiple large screens. Virtual reality typically incorporates auditory and video feedback, but may also allow other types of sensory and force feedback through haptic technology.

Starting in the early 2020s, virtual reality has also been discussed as a technological setting that may support people's griefing process, based on digital recreations of deceased individuals. In 2021, this practice received substantial media attention following a South Korean TV documentary, which invited a griefing mother to interact with a virtual replica of her deceased daughter. Subsequently, scientists have summarized several potential implications of such endeavours, including its potential to facilitate adaptive mourning, but also many ethical challenges

Growing interest in the metaverse has resulted in organizational efforts to incorporate the many diverse applications of virtual reality into ecosystems like VIVERSE, reportedly offering connectivity between platforms for a wide range of uses
