Advantages And Disadvantages Of Virtual Reality

Virtual reality systems are used for simulating different real life situations on the computer which looks approximately same as the real world. In these tools, user need to wear some special cloths which has sensors attached, these sensors observe and record all the activities and responses of the user. These tools are very useful in training of many technologies like in pilot training of Boeing dreamliner, or some new technology etc.

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.

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,

Virtual reality, also known as VR or computer simulated reality, is a new computer technology that mimic an real or imagined environment, VR simulates a user's physical presence and environment.it does this in a way that allows the person to touch and interact with it. VR aims artificially create a sensory experience for the user, which can include touch, Sight, Smell, and Hearing.

The pros of virtual reality outweigh the cons of virtual reality. Virtual reality help a lot of people that are lonely and giving them some help, maybe boosting their confidence or even providing them with information on how to do something like getting a date. According to the source: “ ‘A lot of people are lonely.’ Anderson admits. ‘ They want some sort of entertainment or companionship or a little bit of both.’” (Article 2, Page 8) This shows how, virtual reality can be used to help out the lonely people, the people that don't have confidence. Virtual reality is more of like a voice for the voiceless. Also, another way virtual reality shows how it has many pros, and those pros beat out the cons the following shows this from the text (My Virtual Girlfriend) : “I’ve been in a real relationship for almost a year and , in some ways, playing My Virtual Girlfriend reminded me of what my boyfriend and my early dalliances felt like.” Furthermore, both quotes support the claim of how people are struggling and disabled people, letting people believe, and it gives a pro over a con. It doesn't let people struggle, it gives people options, and you may ask how? Well, virtual reality allows you to believe that you are this, you are good at this that feeds into your mind and you begin to build your confidence to get that entertainment to go out

This paper will analyze virtual reality to explain what VR is and any drawbacks it may have, how and how much it is being used in education currently, how it is benefiting disabled learners, who are able to have access to it, and what a future with VR may look like.

Virtual reality is an interesting topic. Today, technology develops so rapidly, and it becomes a vital role in society.

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

Sebastian Anthony, senior editor of ExtremeTech.com, focuses on the potential dangers that could become problematic because of the speed of the advancement of the technology and the increasing interrelationship of the virtual-reality world and the real world. He expresses concern regarding the blurring of distinction between the two. An example is Oculus Rift which is a virtual reality headset that puts you inside a virtual world that seems completely lifelike. You can run around, fight, race, fly and create in a way that gamers have never done before. There have been “reports of people experiencing the odd sensation of fraying, blurring the divide between real and virtual that persists for a few minutes after detaching from the headset.” (Anthony, 2014, par.4)

This subject was suggested as a possible topic from the course outline. As it is an area of much interest and controversy was chosen as the direction of study for the paper. Previous research into Virtual Reality (VR), coupled with a particular interest in its architectural application also proved motivating. However, although the direction of the initial research appeared straightforward, after further investigation it became obvious that there were in fact two distinctly different interpretations that could be drawn from the area of Virtualism in Architecture. This division was between whether VR was used FOR architecture (VR used as a tool to aid in architectural design). Or whether it was used AS

(96) Virtual reality (VR) is define as a cybernetic simulation of 3D surroundings which can be interactive through auditory, sensory and visually stimulating equipment, i.e. gloves, headgear or headphones. VR is an incredibly recent development in technology and such has much room to progress with, I believe that VR is the future of animation as the key aim is to transport the viewer into the world we have created, VR being the next logical step as it creates this suspension of belief as well as activating all of the senses we use to perceive the real world.

VR is more than an upgraded version of Cinerama or a theme park ride, as it achieves not only a greater sense of presence, but through the use of computer technology, the capacity to direct one’s gaze and movements so that one can explore and move around inside the illusory flow of images [3]. The main imperfection in simulation at present comes from the difficulties inherent in presenting a sufficiently convincing computer generated image. Presenting a convincing visual input to a human being requires a computer which can handle a vast amount of information. This is both difficult and expensive with existing technology.

Virtual reality defined as to produce and create the effect of an interactive 3D world in which the objects have a sense of spatial presence by using computer technologies. Our perceptual and cognitive system will be presented by precise clues in order for our brain to interpret and understand those clues as outside object in 3D world. In addition, virtual reality suggest a lot of benefits and advantages to education of technical such as delivery information through multiple active channels, addressing of dissimilar learning styles, experiential-based learning and so on ( Bell & Fogler, 2004, p 217).

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.
