Analysis of Virtual Reality
The term Virtual Reality (VR) is used by many different people with many meanings. There are some people to whom VR is a specific collection of technologies, that is a Head Mounted Display, Glove Input Device and Audio. Some other people stretch the term to include conventional books, movies or pure fantasy and imagination. However, for purposes of this research, we restrict VR to computer mediated systems. We would define Virtual Reality as a way for humans to visualize, manipulate and interact with computers and extremely complex data.
The visualization part refers to the computer generating visual, auditory or other sensual outputs to the user of a world within the computer. This world may be a CAD model, a scientific simulation, or a view into a database. The user can interact with the world and directly manipulate objects within the world. Some worlds are animated by other processes, perhaps physical simulations, or simple animation scripts. Interaction with the virtual world, at least with near real time control of the viewpoint, is a critical test for a 'virtual reality'.
Some people object to the term "Virtual Reality", saying it is an oxymoron. Other terms that have been used are Synthetic Environments, Cyberspace, Artificial Reality, Simulator Technology, etc. VR is the most common and sexiest. It has caught the attention of the media.
Types of VR Systems
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.
Window on World Systems (WoW)
Some systems use a conventional computer monitor to display the visual world. This sometimes called Desktop VR or a Window on a World (WoW). This concept traces its lineage back through the entire history of computer graphics. In 1965, Ivan Sutherland laid out a research program for computer graphics in a paper called "The Ultimate Display" that has driven the field for the past nearly thirty years.
"One must look at a display screen," he said, "as a window through which one beholds a virtual world. The challenge to computer graphics is to make the picture in the window look real, sound real and the objects act real."
Video Mapping
A variation of the WoW approach merges a video input of the user's silhouette with a 2D-computer graphic. The user watches a monitor that...

...irplane that the inspector can navigate through via voice commands to mark a region of the airplane that is in need of service. Once identified, the application tags the area for transmission to the maintenance database and initiates the proper form for the inspector to fill out. The form is completed and then transmitted to the same maintenance database. When the inspector has identified all of the problems with a particular region, voice navigation is used to continue to other areas of the aircraft. The inspector is not required to take any information about the aircraft, previous defect records, clipboards, paper, etc. with them, everything required to perform the inspection is on-line and displayed in a manageable fashion in real time during the inspection. When the inspector completes the inspection, no further input is required. The inspector is not required to take notes and then pass them off to someone else to decipher and input to the system. The information is already in the maintenance database and ready for verification, planning, and scheduling.
The timesaving realized from start to finish of that inspection is 30-50% depending on the inspector and the aircraft.

Architecture, like many things, can also be made for the use of or inspired by the symbols people believe in. Therefore, art and architecture in Ancient Mesoamerica can be stated to be made for the use of religious symbols. Making architecture and art forms takes effort, dedication, and patience. Architecture can take years to make, as was s...
In 1965 President Johnson signed both Medicare and Medicaid programs into law (Nile, 2011). According to Medical news today, “Medicare is a social insurance program that serves more than 44 million enrollees as of 2008” (MediLexicon International Ltd, 2011, para2). It cost about $432 billion or 3.2% of GDP, as of 2007(par2).Medicare is broken down into parts, Part A is hospital Insurance Part B is medical Insurance, and Part D is Medicare prescription drug coverage (medicare.gov). Like we previously stated Medicare is a health insurance for people who are 65 and older, people under 65 with certain disabilities, and people of any age with End- Stage Renal Disease. Medicaid is a joint federal-state program of medical assistance for low income persons (Benefit.gov). It is administered by the Illinois Department of Human Services (DHS) and Illinois Department of Public Aid (IDPA). Medicaid serves about 40 million people as of 2007; it cost $330 billion, or 2.4% of GDP, in 2007.(par.2) “In Illinois you may be eligible for Medicaid if you are a child, pre...
Discover a universe of possibilities and explore the world like never before. Virtual Reality (VR) brings you to distant lands, places you in the middle of an Elvis Presley performance and brings you face to face with an inhabitant from a different universe.
Implemented (along with Medicare) as a part of the Social Security Amendments of 1965, Medicaid’s original purpose was to improve the health of the working poor who might otherwise go without medical care for themselves and their families. Medicaid also assisted low income seniors with cautionary provisions that paid for the costs of nursing facility care and other medical expenses such as premiums and copayments that were not covered through Medicare. Eligibility for Medicaid is usually based on the family’s or individual’s income and assets. When the ACA came into effect in 2010, it began to work with the states to develop a plan to better coordinate the two ...
Medicaid is a broken system that is largely failing to serve its beneficiary’s needs. Despite its chronic failures to deliver quality health care, Medicaid is seemingly running up a gigantic tab for tax payers (Frogue, 2003). Medicaid’s budget woes are secondary to its insignificant structure, leaving its beneficiaries with limited choices, when arranging for their own health care. Instead, regulations are set in order to drive costs down; instead of allowing Medicaid beneficiaries free rein to choose whom they will seek care from (Frogue, 2003)
Supreme Court have rule differently. The U.S. supreme court have ruled that states now have the choice to pull out of the Medicaid Expansion. Florida is one of the state that has not made a decision to expand Medicaid. “According to the U.S. Census Bureau, Florida has the second-highest uninsured rate in the country, with 24.3 percent of residents lacking health care in 2013” (Reilly, 2015). The causes of Medicaid expanding it to make health care more affordable for millions of American, and it makes the eligibility requirements more broad. Medicaid expansion would provide people without dependent children a chance to apply for benefits, and pregnant women. Some of the consequences of Florida not expanding its Medicaid include the cost of hospital bill falling on taxpayers, leaving a lot of people uninsured, and the state’s rate of uninsured would remain the same. The competing ideology forming around Medicaid expansion is that States are pressured into expanding because they stand to lose more money by not expanding, and it
While President Harry Truman had proposed a centralized health care scheme in the late 1940’s, the bill failed to pass in Congress. With Lyndon Johnson’s strong leadership and gift of persuasion, Congress enacted both Medicare and Medicaid on July 30th, 1965 as amendments to the Social Security Act. Medicare and Medicaid became the United States first public health insurance programs. Medicaid became a federal-state partnership program in which voluntarily participating states would receive grants for those eligible in a state to access a defined set of medical and long-term care benefits.

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.
Using a MUD does not require the paraphernalia commonly associated with virtual reality. There is no special hardware to sense the position and orientation of the user’s real-world body, and no special clothes allowing users to see the virtual world through goggles and though through “data gloves”…Instead of using sophisticated tools to see, touch and hear the virtual environment, users of MUD systems are presented with textual descriptions of virtual locations. Technically, a MUD software program consists of a database of “rooms”, “exits” and other objects. The program accepts connections from users on a computer network, and provides each user with access to that database…Within each system users can interact with each other and with the virtual environment which the MUD presents to them (Reid, 1994).
Virtual reality can be defined as a, "technology that enables users to enter computer generated worlds and interface with them three dimensionally through sight, sound, and touch" (Newquist 93). Virtual reality combines computer simulation and visualization into a single, coherent whole (Peterson 8). Researchers say it embodies an attempt to eliminate the traditional distinction between the user and the machine. Virtual reality is intended to provide a means of naturally and intelligently interacting with information (8). Virtual reality is contending to be the interface of the future, allowing ordinary users to use their senses to interact with complex data.
The whole in Chapter 2 is a critical literature review. In this chapter, it discussed on the VR and types of VR. In addition, it also discussed on the AR area include components, display, issues, definition, differential VR and VR. This also covered that cognitive development theory, learning theory, and learing style. All reviews are followed with the implication for each topic to this study.
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
Virtual Reality is a new form of interactive media that is here to stay. A time may come when people might get tired of it but the chances of that happening are really low as the content that can be offered in VR systems is almost limitless.
“Augmented Reality has the ability to give the user the sense of the real world, while interacting with the virtual and physical objects.” (Azuma, 1997).
