Outline: Article examines uses and benefits of Virtual Reality Technology for persons with disabilities.
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.
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 "virtual" 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 viewing screens.
Virtual Reality, Augmented Reality and Immersive
What is 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.
What is Augmented Reality?
Augmented Reality (AR) is 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.
What is Immersive?
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.
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."
HTC Vive provides the full VR experience with room-scale gameplay, precise motion tracking and natural controller gestures. Vive is brought to you by HTC and Valve
Virtual Reality in Use Today
- Virtual Reality Concert: Fortnite and DJ Marshmello put on a virtual reality concert in the game world. For the first time in the mankind history, fans from all around the world were brought together at a concert venue without having to schedule or pay for any travel accommodation, all possible thanks to virtual reality technology.During the game, players were virtually transported to a massive arena where Marshmello gave an impromptu concert for the fans - (https://coyotechronicle.net/can-you-party-with-virtual-reality-with-headset/).
- Google Maps now offers Street View via virtual reality. And Google Business View takes people inside of restaurants, departments stores and even movie and TV sets.
- Honor Everywhere has created VR experiences for aging or terminally ill WWII veterans so they can virtually visit war memorials.
- In a clinical trial a virtual reality tour of the operating room prior to anaesthesia helped reduce preoperative anxiety in children scheduled to undergo surgery. Children scheduled for elective surgery under general anaesthesia watched a 4 minute VR video showing Pororo the little penguin visiting the operating room and explaining what is in the operating room in a friendly manner.
- There are VR systems which enable wheelchair users to navigate a virtual world, for example a busy street or shopping center, to learn how to move around and avoid obstacles in a virtual setting before putting these into practice in the real world.
- Virtual Reality for Children with Disabilities: Technological advances, including the use of virtual reality, have contributed enormously to improving the treatment, training, and quality of life of children with disabilities. This paper (www.cybertherapy.info/ves%20in%20clinical%20psycho/McComas.doc.pdf) describes the advantages of VR for children with disabilities, how VR can minimize the effects of a disability, the role of VR in training and skills enhancement, and how social participation and the child’s quality of life may be improved through the use of VR.
- Researchers at The University of Haifa, Israel have developed a system that features a number of scenarios designed to teach autistic children how to cross a road. Virtual reality is also used to help autistic children with social attention problems.
- Vanderbilt VR Adaptive Driving Intervention Architecture (VADIA) virtual reality simulator is specifically designed to help teenagers with autism spectrum disorders (ASD) learn to drive
- The University of Georgia and the Georgia Institute of Technology developed a program called BreakThru to help students with disabilities pursue STEM careers.
- Virtual Reality is being found to be useful in testing the design of buildings for disabled access before they are built.
Virtual Reality Viewers
Google Cardboard VR headset, shown assembled with an iPhone 6s in the visor slot. Google Cardboard is an inexpensive container and plastic lenses designed to turn a phone or small tablet into a VR headset.
Google Cardboard is a virtual reality (VR) platform developed by Google for use with a head mount for a smartphone. Named for its fold-out cardboard viewer, the platform is intended as a low-cost system to encourage interest and development in VR applications.
Users can either build their own viewer from simple, low-cost components using specifications published by Google, or purchase a pre-manufactured one.
To use the platform, users run Cardboard-compatible applications on their phone, place the phone into the back of the viewer, and view content through the lenses.
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 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 for $2 billion.
The Rift has two Pentile OLED displays, 1080×1200 resolution per eye, a 90Hz refresh rate, and 110° field of view.
The device also features rotational and positional tracking, and integrated headphones that provide a 3D audio effect.
The HTC Vive is a virtual reality headset developed by HTC and Valve Corporation.
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.
The headset uses "room scale" tracking technology, allowing the user to move in 3D space and use motion-tracked handheld controllers to interact with the environment.
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.
Immerse yourself in extraordinary new worlds, put yourself at the center of an incredible gaming universe and experience a new way to play with PlayStation VR.
With over 150 games the PlayStation®VR headset was engineered to be balanced, comfortable, and adjustable. It's designed to feel like it's not there - keeping you free from distraction as you explore new gaming worlds.
The PlayStation VR system can output a picture to both the PlayStation VR headset and a television simultaneously, with the television either mirroring the picture displayed on the headset, or displaying a separate image for competitive or cooperative gameplay.
PlayStation VR works with either the standard DualShock 4 controller or the PlayStation Move controllers.
A Word of Warning
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...
