Virtual reality (VR) can be defined as softwares that are used in the field of computer technology to create realistic environment through images, sounds and other sensations that actually reproduce the real environment. They create an imaginary setting helps the user to feel his physical presence in this environment. Through virtual reality the user can interact with the space and the objects depicted in the setting using specialized display screens, projectors, etc. It is more of a realistic simulation of a 3D environment using software and hardware that can be controlled by the human body. Virtual reality can be achieved by using a range of systems starting from headsets, omni-directional treadmills to special gloves, etc.
This article concentrates on a new and innovative form of therapy which is based upon virtual reality. Computer based therapies and autism Computers are used as a form of therapy for autism but virtual reality is a fairly new addition to technology based therapy. It is used to help autistic adults or children develop the skills necessary for independence which we take for granted. A virtual environment is an ideal way of teaching these skills before encouraging the autistic person to try these out in the real world. Plus there is the added bonus of doing this in a safe
AR technology then contributes the 3D graphics as they would appear from the viewpoint of the camera, superimposing the computer-generated images over a user’s view of the real world. In Virtual Reality, the computer uses similar sensors and math. However, rather than locating a real camera within a physical environment, the position of the user’s eyes are located within the simulated environment. If the user’s head turns, the graphics react accordingly.
Virtual Reality is where people can create a virtual world where discoveries can be made, and almost anything can be modeled. The possibilities are endless. Augmented Reality is Virtual Reality presented in the natural world. These AR (augmented reality) glasses are being meshed into our everyday lives and jobs. Scientists predict that these glasses will be in our lives as much as smartphones are.
All these senses work by combining signals to the brain and the brain will process the signal, then produce a movement or thought. Everything we know about reality comes from our senses. In other words, what we can feel in the realm of reality is the coming of our senses. So, in simple terms, virtual reality is the 3-dimensional environment stimulation by the computer to stimulate our senses. People who are in virtual reality can view, observe and interact
So what is virtual reality? Answer is simple – it is virtual environment that is created by gadgets, software and even artificially created sensing experience that is presented to the user in such a way that he believes and accept it as a real environment. Virtual Reality varies from augmented reality. In virtual reality, the real world is completely blocked out and a virtual world is created, whereas in Augmented reality adds to the already existing real world. Virtual reality is created by artificial sensory experiences like sight, sound, touch and smell.
They are created and accustomed in such a way that they cannot be modified or get disfigured or breakdown in the hostile environment. Difficult exploration is also an advantage of having an AI programmed in a computer. AI programmed can be used in many ways, it can be used by exploring ocean floor, it can be used in mining, it can be used in fuel examinations process or surveying Fuels and it can overcome human Limitations. Also they can perform more laborious work with greater responsibility. Moreover, they do not wear out easily.
This equipment connects people to the virtual reality and allows them to control and navigate their actions in an environment meant to simulate the real world. Nevertheless, AR is being used more and more in mobile devices such as laptops, smart phones, and tablets to change how the real world and digital images, graphics intersect and interact. In conclusion, both AR and VR are increasingly used in technology, brings us a lot of advantages. They are the most exciting technologies nowadays and promising to bring a lot of change in how people communicate with technology in the future. When we understand and perceive them, we will apply them
The Augmented Reality Environment on the other hand, is augmenting one’s real environment, by adding various computer generated interfaces & models into it. It is often added as an overlay on top of a real world object and is often
Abstract: Augmented reality increases the user’s perception and interaction with the real world. Augmented reality makes use of both virtual and actual reality to make users available with the applications and tools to ensure the transfer of knowledge in different environments. AR displays superimposed information in the user’s field of view and can take him into a new world where the real and virtual worlds are tightly coupled. The ultimate goal of augmented reality is to create virtual objects that are so realistic such that they are difficult to distinguish from the real environment. This paper describes the various characteristics of augmented reality as well as its applications in various fields like medical, entertainment and military
