Disadvantages Of Virtual Reality

In the past, virtual reality technology was thought of by many as a gimmick, and the hope for it to become a mainstream technology was discarded as products did not work as how the public envisioned. However, the proper technology is now available to make virtual reality just that: a reality. The entertainment industry is on the verge of a monumental paradigm shift that will completely transform the way these entertainment mediums are experienced.

The fear of heights can sometimes leave people frozen in terror. There is large amount of evidence suggesting that virtual reality therapy has successfully helped alleviate conditions similar to PTSD. This is accomplished by slowly increasing the amount of stressors, as to not overload the patient with irrational fear. For example, with fear of heights, researchers can gradually increase the difficulty of the simulation, so that the height of the platform increases after every session. In a similar case study, 49 patients had volunteered to participate in a virtual reality treatment for their fear of flying. Results showed, “By the 6-month follow-up, 90% of treated participants had flown since completing treatment” (Anderson 2001). Effectiveness also hugely depends on plausibility and affordability. We need to consider if this treatment is convenient for

For their study, “47 undergraduate students at a Midwest university” were gathered through an online sign up process in which no demographics were collected in the study and the participants had the motivation of receiving class credit for their participation (556). Out of the 47, 2 participants were excluded from the final result due to problems with the procedure, leaving a total of 45. These individuals took part in a virtual reality simulation designed to help people overcome fear of heights. Each participant wore a specially designed set of goggles that allowed for the wearer to have a 360 degree view of the virtual environment and was given a hand-held controller to control their movements throughout the environment. The environment consisted of

Human experience in VR is typically distilled into the words presence and immersion, though immersion is a term used to describe only the technological aspect of VR (Slater & Wilbur, 1997). Instead, the subjective feelings associated with VR are measured in terms of the amount of presence felt in that environment. Intuitively, one would think that photo-realism is paramount to the feeling of presence in a virtual environment, but research has shown that this is not necessarily the case (Zimmons & Panter, 2003), with factors such as bodily representation (Slater & Usoh, 1994) and freedom of body movement (Slater & Steed, 2000) having a greater impact. Interestingly, belief that the virtual environment and real-world environment occupied by the participant are the same increases the feeling of presence in that virtual environment (Bouchard et al., 2012). Some have suggested that, ultimately, cues from other modalities, such as audio and haptic feedback, are necessary for our brain to believe VR experience (Ravassard et al., 2013); however, somewhat surprisingly, strong feelings of presence in VR can be achieved during fMRI, where the head is fixed, and loud noises are occurring (Hoffman et al., 2003). As mentioned, though, presence is greater when the participant has the ability to freely move (Slater & Steed,

By using virtual reality, VA researches can recreate a PTSD suffers traumatic memories and develop treatment based on actual experiences. Chris Crowe, PhD, a researcher and psychologist with the Atlanta VA Medical Center is enthusiastic about the process and states "We believe this has very exciting potential to treat people very quickly and in a way that makes them less vulnerable to relapse,"(VA outlines PTSD research, 2010) These types of research studies are providing veterans with a better quality of life and allotting the time researchers need for long term

In your life, have you ever thought about using virtual reality? Have you ever taken to time to actually look at and think about both sides of virtual reality? Well virtual reality, is good and many people doubt that because of all the cons. But there a lot of pros that defeat these cons. It won't only help you, but it can make you happier and proud. People like to believe in a lot of things, but not everyone sees both sides of everything, especially when it comes to virtual reality. Virtual reality, it develops people it guides people. It’s like being you and creating yourself in the form that you can feel best in. It can be used to do a lot of things but many people are blind to that and just see everything one sided. Virtual reality should be allowed because it’s helpful to struggling or disabled people, therefore virtual reality isn't a cancer to the world, it’s a solution.

Botella et al. (2010) evaluated the efficacy of VR apparatus called Emma’s world. Emma’s world consisted of a large screen projector which included virtual objects, music, sounds, images, colors, videos and texts designed to represent various traumatic events. The control condition included in-vivo and imaginal

Transcript from our interview with Dr. Pretorius, Orthopaedic Surgeon: He says he is not aware of any virtual reality training for orthopaedics. The traditional training for arthroscopic knee surgery was either on cadavers or they would do arthroscopies on public patients (while they were registrar's) with severe osteoarthritis - which means they get a bit of practice on a living patient, without the chance of doing any damage. He says that he thinks training in virtual reality would be a useful tool, but will not be as accurate as/good experience as working on cadavers or live patients - giving you more exposure to real life complications and individual anatomy of patients - Dr Willem Pretorius, Orthopaedic Surgeon

Virtual reality(VR) is a relatively new frontier in the technology industry. So new in fact, that, at its current stage, what it is and its potentials are unfamiliar to the general public. VR originally started gaining momentum as a new platform to game on, but its potential must be analyzed broadly in more than just one vocation. Because of the immersion VR provides, it has an immense capacity to benefit the educational field. Everyone is unique in the way they learn best; some people learn best by reading, some people learn audibly better, and, some people learn visually.

Consequently, virtual reality (VR) therapy is now an alternative that is frequently used as a standard exposure treatment for heights and flying phobias (as cited in Rothbaum et al., 2002, P.428-432). While the professional VR system could be relatively expensive, the study conducted by Malbos, Mestre, Note, & Gellato (2008) suggested that a multi-component therapy that involve VR exposure using mainstream video-game level of editor with powerful 3D engines would also be effective comparing to the professionals after eight

Though putting a mentally ill person in a controlled environment, where scientists can observe he or she, while they put the patient through some sort of exercise, Doctors can receive a better understanding on how to treat the patient. Sometime the Virtual Reality experience is the treatment itself. When someone, like a veteran, has PTSD, for example, he or she can be treated with virtual reality experiences of certain memories, helping them emotionally overcome the traumatic experience. Also, V.R. technology can help social disorders by merging them into social settings that are not threatening to the person with the disorder, thus, helping make him or her to become more social. Last, a more sensitive subject, V.R. can help people overcome his or her fears by, again, showing their fears in a different way to make the fear less frightening. For example, if a person has a fear of spiders, he or she could be put into a situation that teaches his or her brain that spiders are not something to be feared, maybe be put into the spider's point of view to get a sense of what it is like to be a spider. However, Marshall talks about how some people say that it could also be used for torture, perhaps, V.R.could be used to expose terrifying scenes (like death or

Medical Applications of virtual and augmented reality: Virtual reality is an interactive simulation that makes you feel like you are somewhere you are not. It is now starting to be used in the medical field. For patients that are in pain, virtual reality can be used to make it seem like they are in a different happier place. Studies show that it has the same effectiveness level as morphine, possibly even more effective. For therapists who help people with different fears, virtual reality can help conquer the fear. For example, a virtual reality for people suffering arachnophobia allows people to experience what it is like to have spiders surrounding them. Virtual reality can also be used for surgical training. Surgeons can practice surgery without the fear of hurting or injuring an actual patient. This is helpful because if they mess up, they do not have to deal with the consequences that come from surgical mistakes. Virtual reality is a very new and upcoming idea, and in the near future it has the potential to become much more common in a healthcare

First, a study with only forty-nine subjects is a small sample size and not large enough data to state that the virtual reality trainings were significant. With that being said, the study stated to collect data over a long period of time however the collection period was only four weeks; in the rehabilitation world four weeks is not long at all. It would be suspected that a longer collection window would be needed to see results that would be able to be compared and analyzed further in regard to pre-and post-treatment. The pre-treatment was also collected after the second training, which creates a shorter time period and not valid control data. The study also completed a within-subject t-test, which means that there are some individual factors that can contribute to the findings compared to separate control and experimental groups. After reading this article there is not significant data to validate that virtual reality is helpful for those individuals suffering from vestibular

Today’s science fiction is often tomorrow’s reality. As the pace of change has quickened, so it appears that we are actually living within a science fiction movie. Programs on TV continue to amaze or frighten us with yet more technological break through and with clever new products and gadgets. Over the last decade and certainly through the rest of this century, the major agent for these changes has been and will continue to be electronic computer and its derivatives. The Digital Age exploded into existence not with a whimper but a bang. The globe still shakes from its entry. The journey was long, but the impact is immediate. Now, for instance, the breath of an unborn baby can be captured and rendered visible, the

Seeing is believing, these words are the best combination to understand the meaning of Virtual Reality (VR). VR is one of the best asset and aspect of our future. No other technology has seen such a revolution like VR has. It is practically in use in almost every field such as entertainment, gaming, defense, robotics, medical, healthcare, military, education, fashion, heritage, business, engineering and many more fields. VR sometimes called Virtual Environment has drawn much attention in the last two decade. Extensive media coverage causes the much more rapid increase in the interest of the masses. Very few people, however, really know what VR is and what are its open problems are. In this report a historical overview of virtual reality is presented, basic terminology as an introduction are listed, followed by applications of this technology in science, work, and entertainment areas. Its present developments are thoroughly discussed in this report. Finally, the future of VR is considered in two aspects: technological and social. New research directions, technological frontiers and potential applications are pointed out. The possible positive and negative influence of VR on life of average people is speculated.
