Introduction Virtual reality is a virtual environment that is created to try to simulate reality. Its intent is to allow a person to enter a different “world” of 3-Dimensional space. There are different types of virtual reality, which are coordinated by seven different categories of virtual reality: Immersive First-Person, Augmented Reality, Through the Window, Mirror world, Waldo world, Chamber World, and Cab Simulator Environment (Jonassen, David H.). While all types have validity in their practices, Immersive First- Person systems stand out when people think of virtual reality. Immersive First-Person focuses on putting the person in a first person view inside the images, which are made to look real in the realm of visual perception. Several systems already exist and more are currently being designed to simulate this fully immersive environment, along with interface and input devices to make the simulation even more realistic. This technology can be used in multiple fields and research, including combat training or medicine. Systems One of those systems that exist already is the head-mounted display (HMD). The head-mounted display comes in many shapes and sizes but is basically headgear, consisting of a large helmet or a pair of goggles that envelop your entire scope of vision, blocking out any sight of actual reality. There are three different ways that a 3-dimensional video format can be produced. One option is that the headgear contains two small screens (one for each eye), which display slightly different images based on what that eye would be seeing in reality. Secondly, the headgear can have one screen that combines the two video feeds for each eye and alternates the video feeds in consecutive frames. The third approach is... ... middle of paper ... ...sured amounts. Since it is virtual reality, the patient feels like they are actually facing this fear but they know there is no actual danger (Yang, Heewon). These are just some of the many possibilities for this technology, and the possibilities will continue to grow as the technology advances. Conclusion Although advances have already been made in vision and sound capabilities in virtual reality, virtual reality will continue to grow, and should eventually be able to envelop all the senses including taste, smell, and touch. As time moves on, the images that these virtual realities will be able to show will definitely increase in sharpness and clarity. Movements will be tracked more rapidly and realistically. With such a promising future, virtual reality will gain quality while at the same time becoming being cheaper, more portable, and increasingly sought after.
The film industry has always been a modern industry where new inventions are constantly on the rise and put into films to improve the film lovers’ movie experiences. Just a few years ago, the world was introduced to a new third dimension. Instead of just using your imagination to put yourself in the same room as the characters on the screen, the 3-D effect did it for you. In Roger Ebert’s “Why I Hate 3-D,”
Virtual Reality got famous from the gaming industry and from sci-fi movies. In science fiction films there were numerous scenes about person wearing goggles and then looking into a different world or a portal. Things which are presented in movies do fascinate the viewers and so the real Virtual Reality concept came to life. This thing was also seen from the gaming industry as one of the biggest Graphics Processing Chip Company NVidia built its first stereoscopic goggles called NVidia 3D vision. The sole purpose of those glasses was to wear them while playing a game and it will make you feel like you are the character and you are inside the game. Some of the games which made this technology popular are Battlefield, Batman, HAWX and

Virtual worlds such as Second Life and IMVU — which show a 3D environment on a 2D screen rather than immersing the user inside a room or by using an HMD — and the more recent rise of Oculus Rift have all contributed to the rekindled interest in VR. However, major technology and usability advances are still required for a low-cost, broadly used immersive virtual environment. In the meantime, growing popularity of 3D entertainment using 3D glasses — and, increasingly, 3D smart television screens and projections that do not require glasses — may relegate immersive VR to permanent niche status. Currently, augmented reality applications (which superimpose information on the user's view of the real world rather than blocking out the real world) or mixed-reality scenarios (where HMDs and context-aware software are used in a hybrid augmented/virtual environment) are more popular technology approaches to the problem of marrying immersive VR to a consumer
The purpose of this paper is to explain how virtual reality is used in everyday life. It is used in many ways in today's society. Several people immediately think of video games or entertainment when they hear virtual reality. Virtual reality is not only used for entertainment purposes but it is also used for medical and educational purposes. It can help people overcome their fears, deal with and treat social anxiety, and it can also be a helpful teaching tool to connect students and teachers in long-distance learning.
So what are other things VR is being used for today? Well according to the article titled “Beyond Gaming: 10 Other Fascinating Uses for Virtual-Reality Tech” By Knvul Sheikh ( a staff writer for livescience.com) there are a heedful of other things that are being done with VR. So let’s go over some of them. Well one of the things that Sheikh talks about is Space and how astronauts have been using VR. One of the things that they are doing is that they are using VR technology to control robots on Mars. They also added a Virtuix Omni treadmill to their VR setup and now researchers are able to simulate a walk on Mars to prepare astronauts for a potential human landing. (Sheikh,
A major distinction of VR systems is the mode with which they interface to the user. We would describe some of the common modes used in VR systems.
30 years ago, virtual reality or VR was not even thought of. And now we have advanced virtual reality gaming setups costing thousands. Virtual reality has been around for roughly 10 years now and some say that is it here to stay, while others say it will die off soon. I am a gamer at heart but have not been around virtual reality enough to know all about it, other than the fact that it is fun and seems like we have only scratched the surface. My goals are to gather a bit more knowledge on current virtual reality tech, what’s to come of virtual reality, and virtual reality’s effect on gaming.
A young cinematographer by the name of Morton Heilig once said “If we're going to step through the window into another world, why not go the whole way?' (Tate,Scott 1996) In 1957 he created the device known as the Sensorama. The device was designed to use all your senses and also projected a form of stereoscopic 3D to the front and the sides of your head. It was patented the "experience theatre", however it failed to work commercially because it was very expensive to make films and the process was t...
Over the years society has changed in many different ways. In particular, technology has been the largest change that has occurred over the year. Only a few years ago the iPhone came out and it has forever changed the way people view their phone. Internet has also become very assessable resource. There are places everywhere to access a computer or free Wi-Fi. These changes have led to the alteration of the accessibility and use of technology in the education setting. The changes made to technology in the education setting have led to many positive outcomes that have allowed many types of people access to education that could not get it prior. There are however, many critics that refute these changes and say that virtual education can be biased and expensive. Although, there are many critics that do not agree with technology in education, have this can give access to many students with disabilities as well as people who have limited time or ability to further an education.

Virtual reality is a new exploration in science and technology using advanced and complex mechanics. Virtual reality allows for users to go far beyond simply looking at a computer screen. Instead, the user puts on a special suit or gloves equipped with fiber-optic sensors. These fiber-optic sensors are able to interpret body positions. The user also wears special goggles that have video screens and audio attachments. This equipment allows for the user's complete immersion into a 3-D, computer generated, model of reality (Carr 37). The use of a two-way data transfer is what enables this interaction with an alternate reality to occur. Fiber-optic and electronic cables are attached to the virtual reality equipment in order to record the user's movements (Newquist 93). These cables then send this information, called motion data, to workstations which modifies the graphics in the model. The new information is then sent back to the users headset, displaying a graphic and audio world that is time with his or her movements. It is because of this cabling process that the action/reaction information is continually updated (93).
Definition of virtual reality is "A technology that assures participants that he was actually in another place by replacing the main sensory input with data received by the computer" [6] [10]. One of the key elements of the virtual reality of cyberspace; it is a space fantasy or simulation environment. Which is always linked here is a virtual world and immersion virtual reality, perception is born into the world of alternatives such as ethereal or other point of view of our world
There is no denying the fact that VR is the future. If you see industry trends, the rate at which VR is becoming mainstream is staggering as almost 75% of the biggest corporations are now investing in this technology. They see the potential and the interest the people have and are constantly working on improving the current virtual reality systems.
Augmented reality (AR) is the virtual object which is combination of 3D real environment in the real time. It is more interactive either with graphics or audio enhancing from what we can sense such smell, hear, see or feel it. In other words, it is duplicate the environment around the world in computer. There are applications in various areas in augmented reality and one of them is medical visualization more domain for augmented reality. The topic that discussed is augmented reality application in computer aided surgery and medicine. In research article (Tobias Sielhorst, Marco Feuerstein & Nassir Navab, 2008) medical augmented reality takes it motivation from the need of visualizing medical data and the patient within the same physical space. The reason for chose this topic because it is because this application more advance and the technologies always bring new visualization and interaction using augmented reality in 3D in surgery performing requirements. So, discussing these topics actually need many evaluations to perceive the result to the area of surgery and medicine in medical performance.
