Virtual reality can be explained as the experience taking to a similar or different real world environment which is a computer generated reality. The environment is non-physical world which developed with the proper usage of software and hardware. The hardware are the entity that makes the environment real. The connection between human and system is made possible by using the human-computer interfaces. Computer graphics plays a vital role to make the environment feels like a real concept.
Virtual reality gains its attention during early 1990s which was a success in the field of entertainment. Now in the present state the application of virtual reality goes beyond entertainment. It becomes a very helpful concept in the field of Automobile, Education and Healthcare. The concept of VR is a challenging to tackle the presence of designing VR systems that really transport humans to a new world with an acceptable sense of presence. The extreme usage of VR is applied in the games where the players plays like in the real world.
In-order to support the development giant companies such as Apple, Google etc have their own kits like ARKit, Daydream, google cardboard etc. After years of experimentation the development of VR is not getting viable, still more to go. There are lot of business and technical challenges which VR is facing. Latency in drawing, spherical sound design, cost and streaming and compatibility with hardware are some of the most faced technical challenges.
The application of VR in the field of medical care is very impressive. The amputees are using VR to get rid of phantom pains.In Sweden in the Chalmers University of Technology, the experiment was conducted. Patient with an amputated hand could see how he was driving a car in the virtual reality. The motion sensors have been hooked up to his limb. His brain got the visual confirmation that his amputated hand was moving and reacting on movement. The intensity and frequency of pain have decreased after the experiment.
