Imagine being a wheelchair user, putting on your VR headset, and the next moment you are flying over a mountain range. Or having a phobia and being able to face the fear under observation in a VR environment. Virtual reality is "immersive," it gives the user a "presence" and the chance to give somebody access to something that they may never see in real life.
Virtual reality - Virtual realities (VR), also known as immersive multimedia or computer simulated reality, is defined as computer technology that replicates an environment, real or imagined, and simulates a user's physical presence and environment to allow for user interaction. Virtual realities artificially create sensory experience, which can include sight, touch, hearing, and smell. The immersive environment can be similar to the real world in order to create lifelike experiences.
Augmented reality (AR) - A live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified by a computer. Various technologies are used in Augmented Reality rendering including optical projection systems, monitors, hand held devices, and display systems worn on the human body. As a result, the technology functions by enhancing current perception of reality.
Using current VR products like the Oculus Rift, the HTC Vive and Playstation Virtual Reality, VR is already being used as a tool in medicine to treat phobias, reduce pain and even help doctors perform surgery. Virtual reality projects are also offering new perspectives on what it's like to experience conditions such as deafness, migraines, and depression.
The main benefits identified for disabled people are that they can engage in a range of activities in a simulator relatively free from the limitations imposed by their disability, and they can do so in safety. There is evidence that the knowledge and skills acquired by disabled individuals in simulated environments can transfer to the real world (www.ncbi.nlm.nih.gov/pubmed/9195138).
"For some gamers with disabilities, virtual reality might be a godsend," said Mark Bartlet from The AbleGamers Foundation in an interview with ARC at GDC 2016. "One of the core philosophies of the AbleGamers charity is that games allow disabled people to do things that they wouldn't in real life. And that includes able-bodied people - in virtual reality you can climb Mount Everest, or be an NFL player... most of us can't do that."
For around $15 anyone can buy a VR cardboard headset, download a free mobile phone app, slide in the phone and explore virtual worlds from a wheelchair, bed or couch - Google Cardboard
Oculus Rift headset
Oculus Rift is a head-mounted display for VR and gaming purposes developed by Oculus VR, an American technology company that was acquired by Facebook in 2014.
In 2015, Valve Corporation announced their partnership with HTC to make a VR headset capable of tracking the exact position of its user in a 4.5 by 4.5 meter area, the HTC Vive. Update Nov 12, 2016: Chinese company TPCAST has just unveiled an add-on to the HTC Vive which makes the VR headset completely wireless.
Sony Playstation Virtual Reality
The Playstation VR (Morpheus) requires a PS4 instead of a PC to run.
There are many other gaming VR headsets on the market, and in development, each with their own special abilities.
Virtual reality is fairly new technology and still faces a number of challenges, including possible motion sickness and technical matters. Users can get disoriented in a virtual environment causing balance issues, computer latency can affect simulations, head-mounted displays and input systems such as specialized gloves and boots may require specialized training to operate, and navigating the non-virtual environment (if the user is not confined to a limited area) can be dangerous without external sensory information.
However, this new technology may open creative pathways for users in ways we don't even realize yet, and for people with disabilities virtual reality might be another route to inclusion...
