Virtual reality ( VR) is a simulated experience that employs 3D near-eye displays and pose tracking to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games ), education (such as medical, safety or military training) and business (such as virtual meetings).
Virtual reality headset. A virtual reality headset (or VR headset) is a head-mounted device that uses 3D near-eye displays and positional tracking to provide a virtual reality environment for the user. VR headsets are widely used with VR video games, but they are also used in other applications, including simulators and trainers.
Virtual reality is being applied to a wide range of medical areas, including medical education, training, surgery and diagnostic assistance for heath staff. For patients it is a good way of using it for their rehabilitation and training. [12] VR began to appear in rehabilitation in the 2000s.

When you think of virtual reality (VR), video games and other types of entertainment might come to mind. But it’s also showing promise as a complementary treatment in medicine. Research is ...
Virtual retinal display. A diagram showing the workings of the virtual retinal display. A virtual retinal display ( VRD ), also known as a retinal scan display ( RSD) or retinal projector ( RP ), is a display technology that draws a raster display (like a television) directly onto the retina of the eye.
Reality–virtuality continuum. The virtuality continuum is a continuous scale ranging between the completely virtual, a virtuality, and the completely real, reality. The reality–virtuality continuum therefore encompasses all possible variations and compositions of real and virtual objects. It has been described as a concept in new media and ...
Virtual retinal display systems are a class of screenless displays in which images are projected directly onto the retina. They are distinguished from visual image systems because light is not reflected from some intermediate object onto the retina, it is instead projected directly onto the retina. Retinal Direct systems, once marketed, hold ...
