Virtual reality is a computer-simulated environment that can be experienced through headsets. The first VR headset was created in 1968. Major developments included Lanier coining the term "virtual reality" in 1987, the release of the Oculus Rift in 2016, and the PlayStation VR and HTC Vive in 2016. VR has applications in entertainment, healthcare, education, and more. The advantages are that it creates realistic simulations and enables virtual experiences, but the disadvantages are that the equipment is expensive and complex and does not allow fully moving between real and virtual worlds.

PlayStation VR (PSVR).
