Description A groundbreaking Virtual Reality textbook is now even better Virtual reality is a very powerful and compelling computer application by which humans interact with computer-generated environments in a way that mimics real life and engages various senses. Although its most widely known application is in the entertainment industry, the real promise of virtual reality lies in such fields as medicine, engineering, oil exploration, and the military, to name just a few.
During the s and s, computer game designers exploited three-dimensional graphics, faster microprocessors, networking, handheld and wireless game devices, and the Internet to develop new genres for video consoles, personal computers, and networked environments.
Numerous precedents for the suspension of disbelief in an artificial world in artistic and entertainment media preceded virtual reality.
Illusionary spaces created by paintings or views have been constructed for residences and public spaces since antiquity, culminating in the monumental panoramas of the 18th and 19th centuries.
Panoramas blurred the visual boundaries between the two-dimensional images displaying the main scenes and the three-dimensional spaces from which these were viewed, creating an illusion of immersion in the events depicted.
This image tradition stimulated the creation of a series of media—from futuristic theatre designs, stereopticons, and 3-D movies to IMAX movie theatres—over the course of the 20th century to achieve similar effects.
The Vitarama process used multiple cameras and projectors and an arc-shaped screen to create the illusion of immersion in the space perceived by a viewer. Though Vitarama was not a commercial hit until the mids as Cineramathe Army Air Corps successfully used the system during World War II for anti-aircraft training under the name Waller Flexible Gunnery Trainer—an example of the link between entertainment technology and military simulation that would later advance the development of virtual reality.
Rowan Sensory stimulation was a promising method for creating virtual environments before the use of computers. After the release of a promotional film called This Is Cineramathe cinematographer Morton Heilig became fascinated with Cinerama and 3-D movies.
Although Heilig was unsuccessful in his efforts to market Sensorama, in the mids he extended the idea to a multiviewer theatre concept patented as the Experience Theater and a similar system called Thrillerama for the Walt Disney Company. Beginning in the late s, Project Whirlwindfunded by the U.
By the time the SAGE system became operational inair force operators were routinely using these devices to display aircraft positions and manipulate related data. During the s, the popular cultural image of the computer was that of a calculating machinean automated electronic brain capable of manipulating data at previously unimaginable speeds.
The advent of more affordable second-generation transistor and third-generation integrated circuit computers emancipated the machines from this narrow view, and in doing so it shifted attention to ways in which computing could augment human potential rather than simply substituting for it in specialized domains conducive to number crunching.
He argued that a partnership between computers and the human brain would surpass the capabilities of either alone. As founding director of the new Information Processing Techniques Office IPTO of the Defense Advanced Research Projects Agency DARPALicklider was able to fund and encourage projects that aligned with his vision of human-computer interaction while also serving priorities for military systems, such as data visualization and command-and-control systems.
In Sutherland completed Sketchpada system for drawing interactively on a CRT display with a light pen and control board. Sutherland paid careful attention to the structure of data representation, which made his system useful for the interactive manipulation of images.
His notion of such a world began with visual representation and sensory input, but it did not end there; he also called for multiple modes of sensory input. Within a few years, Sutherland contributed the technological artifact most often identified with virtual reality, the head-mounted 3-D computer display.
In Bell Helicopter now part of Textron Inc. This was an apparatus shaped to fit over the head, with goggles that displayed computer-generated graphical output. Because the display was too heavy to be borne comfortably, it was held in place by a suspension system.
The HMD also tracked where the wearer was looking so that correct images would be generated for his field of vision.Virtual reality (VR) is a technology which allows a user to interact with a computer-simulated environment, be it a real or imagined one.
Most current virtual reality environments are primarily. Virtual Reality development attracts many students to computer science through the creativity and collaboration involved in VR development projects.
My Project The equipment will be used to implement Virtual Reality programming in computer science classes.
For Good Virtual Reality, the Devil is in the Details All of this hardware would be nothing without the Internet of Things, which may be one reason VR has taken so long to develop. Those positional tracking systems, like the Constellation Tracking System, are incredibly new, and they wouldn’t be possible without the most modern technology.
Virtual Reality History, Applications, Technology and Future of VR systems are listed, followed by applications of this technology in science, work, and entertainment areas. An insightful study of typical VR systems is done.
