Virtual Reality has been a dream of computer scientist and science fiction writers for a long time and certain developments in the computation has made Virtual Reality a reality for the commercial user from 2010. With the release of HTC Vive and Oculus Rift Virtual Reality headsets have made their way into homes and clumsy wired models are soon to go wireless. Their use is as versatile is reality is: from education, training, entertainment, storytelling, treatment, social applications and pornography, virtual reality is here to transform our relationship with media and reality. Elon Musk, the founder of Tesla and SpaceX promised that the landing of SpaceX’s ambitious Mars project will be streamed live in VR – making this the first historical moment that can be lived and relived without people physically participating in the event.

As VR is becoming a reality the question arises on how interactions with this new technology will transform human lives. How will our relationship with reality change? Take the medical application of VR as an example. VR has been used in medical care to alleviate chronic pain, help patients who struggle with PTSD which proves VR’s potential to change our perception of reality. However this same potential can point to dangers ahead that can create lasting psychological effects. Training doctors and pilots in VR can contribute to a better future for humankind, however training software can be used just as successfully to train soldiers or terrorists to perform violent acts. A code of ethics has to be established as we carry on developing VR and its many realities.
