Ijsselsteijn & Riva came up with presence, which is the experience of ‘being there’ in a mediated environment. It has become closely associated with virtual reality (VR) and other advanced media as well as playing role in engendering a sense of presence. There are also different types of presence including the physical presence, social presence, and co-presence (Ijsselsteijn & Riva, 2003). On the other hand, Timmins & Lombard have explained the confusions that occur regarding what is the virtual (mediated by technology) and real (non-mediated). They have stated three categories of the illusion of mediation which are the positive, negative and unusual which are labelled as the inverse presence (Timmins & Lombard, 2005).
• VR relies on a three-dimensional, stereoscopic head-tracker displays, hand/body tracking and binaural sound. VR is an immersive, multi-sensory experience. • Computer replications that use 3D graphics and devices such as the Data Glove allows the user to interact with the virtual reality. • Virtual reality refers to interactive, multi-sensory, and viewer-centered, three dimensional computer engendered environments and the combination of technologies that are required to build these virtual environments. Virtual Reality - Evidence for the Theory In the last years, the progress made in computer science technology has brought faster and faster computers to the market.
An augmented reality system generates a composite view for the user. It is a mix of the real scene seen by the user and a virtual scene generated by the computer that augments the scene with extra information. In every one of those
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.
Unlike virtual reality which completely replace reality, Augmented Reality only adds or completes reality. Augmented reality technology has the goal of creating a system in which users cannot distinguish between the real world and the virtual augmentation. Augmented Reality is used in entertainment, military training, engineering design, robotics, manufacturing and other industries. This technology began to color the world of technology in the last decade and is also able to attract the attention of experts, researchers and IT developers with technology model offered namely make real virtual objects . 2.2 marker Marker is a real environment-shaped objects that will produce virtual reality.
The augmented reality embeds the digital information into the real world. When you engage augmented reality, you are engaging ordinary places, space and objects around you that exist in real. The basic difference between the both is the environment and digital information exchanged. In virtual reality, your senses are exposed to a virtual world due to which you will start feeling as a part of that environment which doesn’t really exist. In augmented reality, your senses remain in the real world.
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 realm of Virtual reality has gained significant popularity over the last few decades as a topic of research, a technological tool and as a source of entertainment. Technological developments over the last few decades have enhanced the realism of the virtual world for its audience. The constant advancement in the virtual world has raised its importance and utility in the lives of people across the world. This has led to the generation of multiple questions and theories about the extent of reality of these virtual worlds. The attempt is to acquire concrete answers on whether a virtual reality experience can ever possess the level of realism of the actual physical reality for the audience or will people always be aware of the fact that virtual
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
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.
