Imagine being able to point into the sky and fly. Or
perhaps walk through space and connect
molecules together. These are some of the dreams
that have come with the invention of virtual reality.
With the introduction of computers, numerous
applications have been enhanced or created. The
newest technology that is being tapped is that of
artificial reality, or "virtual reality" (VR). When
Morton Heilig first got a patent for his "Sensorama
Simulator" in 1962, he had no idea that 30 years
later people would still be trying to simulate reality
and that they would be doing it so effectively.
Jaron Lanier first coined the phrase "virtual reality"
around 1989, and it has stuck ever since.
Unfortunately, this catchy name has caused people
to dream up incredible uses for this technology
including using it as a sort of drug. This became
evident when, among other people, Timothy Leary
became interested in VR. This has also worried
some of the researchers who are trying to create
very real applications for medical, space, physical,
chemical, and entertainment uses among other
things. In order to create this alternate reality,
however, you need to find ways to create the
illusion of reality with a piece of machinery known
as the computer. This is done with several
computer-user interfaces used to simulate the
senses. Among these, are stereoscopic glasses to
make the simulated world look real, a 3D auditory
display to give depth to sound, sensor lined gloves
to simulate tactile feedback, and head-trackers to
follow the orientation of the head. Since the
technology is fairly young, these interfaces have
not been perfected, making for a somewhat
cartoonish simulated reality. Stereoscopic vision is
probably the most important feature of VR
because in real life, people rely mainly on vision to
get places and do things. The eyes are
approximately 6.5 centimeters apart, and allow
you to have a full-colour, three-dimensional view
of the world. Stereoscopy, in itself, is not a very
new idea, but the new twist is trying to generate
completely new images in real- time. In 1933, Sir
Charles Wheatstone invented the first stereoscope
with the same basic principle being used in today's
head-mounted displays. Presenting different views
to each eye gives the illusion of three dimensions.

Quill took two morals decision, to help Diane to commit suicide and lie about the diagnosis of Dianna cause of death. Under the Ethics of cares Dr. Quill did not do what he support to do in Diana situation. Care is a practice of doing an activity consistently over time. A practice need to incorporate standards to evaluate it. Under the ethics of care, helping patients to commit suicide was not constantly being part of his job. Moreover, if we take into consideration doctor standards to evaluate this situation it will not be permitted under doctor’s ethics rules to help patient to take away life. In other words, Dr. Quill actions to lie about the diagnosis of the cause of death is a crime. At that time, helping to suicide was illegal and it was paid with jail. In the ethics of cares, justice is a value and who ever do something wrong under this ethics need to pay for that. In other words, he did not took the best decision to lie about the diagnoses of death and may have to pay with
Is acquired deafness more traumatic psychologically than developmental? Does being deaf have positive characteristics? How does being deaf affect relationships with family and
While reading Mark Drolsbaugh’s Deaf Again where he wrote about his experiences with becoming postlingually deaf, I realized that I was able to relate to some of the situations he encountered, especially when he spoke of his frustrating childhood due to his disability. As he grew older, he needed to find new ways to cope with and accept his deafness. Because of his unique viewpoint with deaf parents who were not allowed to sign around him, the book gave readers a different perspective to look at deafness with. Drolsbaugh’s personal account of his life was inspirational as he grew up with a truly exceptional situation, yet was able to overcome his obstacles and become successful after he quit denying who he really was.
While the benefits for the hearing are great, there are better benefits for those who are Deaf. Jarashow stated that it was essentially frowned upon if a Deaf child was using sign instead of trying to use what ability they had to hear. This seems counterproductive and if they emphasized more on teaching Deaf children ASL, there would be better outcomes for them in the future. Instead of focusing on trying to make everyone the same, they should focus on giving these children the best opportunity possible despite their

A common misconception is that virtual reality is just for entertainment. As we contemplate about some of the technology involved in virtual reality, entertainment is generally the first thing a lot of people think of when virtual reality springs to mind, but here we will talk about some of the other areas that virtual reality has made some substantial differences.
But if we are looking for a more modern take on virtual reality we would start in the early 1800’s with a paint style called “Panoramic paintings”. So what are these and how do they relate to virtual reality. Well these paintings were made to fill a person’s field of vision, making them feel like they are at the historical event, scene, or battle they are looking at. (“History Of Virtual Reality”, 2017).
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.
Augmented reality, is changing how we see the world. Augmented reality isn’t a new technology by any means. However, it is gaining popularity as the hardware and software that allows us to view our world through a new prospective becomes increasingly cheaper. As technology progresses, processers and circuits become smaller and smaller in size. Thus allowing for more capability from various forms of hardware like phones, computers, glasses, contacts, and even your car. All these devices have screens, or windows in which we look at our world, and with cleaver programs, software, and hardware, integrated into these modes which we view the world. The way which we see the world around us will forever change based on our own interests thanks to augmented reality. However, the question we have to ask ourselves is, is ability to overlay our world with whatever we please a good thing, or a bad thing?
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.
This research looks into the potential of augmented reality and more specifically spatial augmented reality. The purpose of this paper is to give the reader an understanding of what as well as where augmented reality has come from and how it is being used today. The paper will examine into different examples of augmented reality and how the term is not specific to a certain technology.
The ethics and morals of using virtual reality with medicine have many faces. Ethics is defined as the way we should act towards others; also the justification of right and wrong, in this case a set rules or expectations that are set forth in the medical profession.
Do we truly understand how the meaning to equality among men and women affect society. Jobs, health, and education are affected by what transpires from the meaning to gender equality. Throughout history equality has been debated. Equality is defined as getting respect and giving respect regardless of gender or culture through fair treatment and maximized happiness. Balance and harmony are developed from the application of ethical theories to aid society in defining the meaning to gender equality rather than debating the issue. Therefore, defining gender equality should be the role of society by utilizing ethical theories. The theories can be consequentialist or nonconsequentialist acts that develop and maintain good morality and ethical
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.
The Purpose of this research paper is to explore the possibilities in virtual reality that helps with education. Is it possible to use virtual reality in the educational system? What does it bring to the table that conventional teachings do not? What other devices are coming to the market that can be used? In this paper we will also be looking at few examples of virtual reality video games that are now used in the glass room or are about to be.
