Virtual Reality
Virtually reality is a broad term that is used in regards to a computer simulated environment that can simulate a real world experience or an imaginary world that can be rather creative. Most of these computer simulations are primarily based on a visual experience however more sensory information is also being created and intergrade into the experience as well. These systems are mostly used for either training or entertainment; sometimes a combination of each. For example, a virtual reality programs are built to teach everything from piloting an airplane to landing a parachute. These training programs can be invaluable tools to help people learn how to perform advanced tasks that are often too dangerous or expensive to practice in real life.

Virtual Reality Input Devices
Although the visual experience has served at the center of the virtual reality experience is it was envisioned, focusing attention on the other sensory organs is what heightens the experience. This has been well-known for some time now. In 1960 a cinematographer named Morton Heilig built a console that allowed users to become more engulfed in a movie. The setup was equipped with fans, odor emitters, stereo speakers, and a chair that moved at certain times during the film to make the viewer feel more like they were actually experiencing the movie as if they were there (Strickland, 2012). Although this technology only allowed movie goers to play a passive role in the experience, the same desire to incorporate more and more elements into a virtual reality still drives the development of the technology today.

Users can now interact with their virtual environment in a variety of ways as well. There are a variety of sensors that can capture a user's movements and integrate these into the experience. A glove was one of the first examples of a body mounted input capture device however now there are full body suits that users can wear to capture their every movement in precise detail. Cameras can also be used as a substitute to a body suit that can serve a similar purpose and track body movements. However, cameras have yet to be able to capture the subtleties of movement as accurately as physical sensors. However, cameras offer a low cost alternative that has been integrated into many popular gaming systems such as the Nintendo Wii that has been introduced the technology on a broad scale.

There are many practical uses…
VIRTUAL REALITY & ITS APPLICATIONS Information Systems This paper will describe the basic components of virtual reality. The paper will also provide a variety of practical applications for this technology in many industries. The paper is a brief summary and brief comparative analysis of the advantages and disadvantages of virtual technology. Virtual technology has been in existence for decades and as time passes, its integration in mainstream culture and everyday life increases.
virtual reality event at a museum. I was really excited to go because I'm always interested in learning more about technological innovation and how it is used in different ways. The new virtual reality technology out there involves the use of multiple cameras that record in all directions and are thus used to create experiences using the captured imagery. The image is thus viewed through the virtual reality goggles. I
Super-violence is a new term that defines violence in a grand and exaggerating way. (Klare 16) Seen as an era of constant warfare and violence, it has made its way into entertainment and media. Whether it is chopping the heads of people and seeing the blood from their bodies gush like champagne fountains or seeing throats slit by children, today's media has taken on a new level of violence that
Despite the existence of this notion, juxtaposition enables montage to deal with cut and paste contradictory pieces and the concept of visual language. This enables the achievement or development of new meaning of the images. It is ideal to note that mass media images were put together, though fake and clumsy, are productive in the production of documentary picture in relation to history (Jenkins 2006, p. 214). This enables
Virtual Religious Service Islam is a religion of great misconceptions and of immense misunderstanding. It was because of this same notion that this religion in particular was of great interest. With all the negative publicity that Islam receives in the media, people only get exposed to the violent extremists that represent a minute minority of this religion. A picture of violence and death is flashed on the television daily, forcing many
There are several characteristic that are evident with the software system use in virtual collaboration technology. The first characteristic is that most of these tools are web based and are downloadable; they also have the ability to offer a text chat feature in real time, thereby allowing for the synchronous communication among various users. The platforms also has VoIP functionality, thereby giving them the ability to transmit sound over the
