Difference Between Augmented Reality And 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 order to catch you up am going to tell you about the inventors and how they initiated this project and where their inspiration came from

Her system had a set of four peep holes and a camera that could slide up and down to look at each one. Anything that the camera saw would appear on the monitor. The system was originally made for domestic uses but many businesses wanted to buy her system since it worked so well. Her invention was so good that she received an award from the National Science Committee. The year she received the award is unknown.

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.

This dual lens camera created a “3d” like image, much like the image the human eyes create. The images were developed and put on to a “stereoview” card, these cards could be bought by the general public and viewed on a personal stereo viewing device that made the images look almost “3 dimensional” to the viewer.

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.

1. Kevin Rio explains that the device was mostly used in bars and arcades up to 1930 when it was adopted in the media as an entertainment tool.

In 1966, Sutherland then went forth and built an HMD that was connected to a computer system. All the graphics were created by the computer system and the HMD could also display images in stereo, giving the illusion of depth.

Herman et all (2002) points out that history of video games begins from 1971 year, when Nutting association released 1500 machines with Spacewar video game. At the beginning it was too difficult to control the game process and playing machines had huge dimensions. But by the time with new technologies they become more compact and easier to play. According to the information given by Herman et all (2002), the period between the years of 1978-1981 is called ‘golden age’ of video game industry. In this period the arcade games ‘Football’ and ‘Space Invaders’ were released. All previously known sale records were broken by these two games with nearly equal wages. In this time interval great breakthroughs in the field of graphics were achieved,

In terms of specific applications VR can be usefully applied when building homes for disabled people. For example, those whose movements are restricted solely to a wheelchair may require larger hallway space for maneuverability and lower bench heights in the kitchen. These can easily be rectified before the house is built. Thus minimising on post-production changes which may be costly. I3 (Interactive Information Institute) is the RMIT VR 'showpiece'. It features a 150 degree wide screen which occupies the entire field of vision of the viewer. Instead of mounting a head display unit the environment is shared. I3 feature an architectural 'fly-through' of the Docklands planned area for development. This allows the user to view buildings from a multitude of different angles, and ascertain an improved idea of the finished product.

VR systems support 3-dimensional graphics, wide angle of view, stereovision, and viewer-centered perspective. In many VR systems the participant is not seated and is free to walk about and gesture broadly. These features make a computer system which is closer to a workshop, an operating room, or a national park than it is to a desk in an office. This perspective allows freedom in the creation of human-computer interfaces that is not afforded by the current standard interfaces [4].

Next, Virtual Reality might be a powerful and sophisticated tool for education in which it can enhances students understanding towards certain subjects. Virtual Reality’s application in education is greatly interactive computer based environment in

With sponsorship from STRICOM, Loral WDL performed the very first demonstration that manned simulators and live AR-equiped vehicle, also in 1993. In 1994, funded by the Australia Council for the Arts, Julie Martin creates the first ‘Augmented Reality production’ entitled Dancing in Cyberspace. It features dancers and acrobats interacting and manipulating with virtual object in the size of a body in real time. The virtual object is projected into the same physical space and performance plane of the performers and they appeared immersed within the virtual environments and object. Polhemus sensing system and Silicon Graphics computers are used in the settings and installations

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.
