Virtual Reality is a future technology which makes the use of Virtual headsets to generate realistic image view, sounds and other sensation which gives the information of the presence of the User in an imaginary environment. A person using Virtual Reality is capable of viewing of the artificial world with immensely high quality. Virtual Reality hardware consists of a head mounted Goggles with a screen in front of the eyes.VR system includes audio through headphones and speakers.
VR uses Haptic System that enables the transmission of vibrations and another sensation to its user through this device. Sometimes, it also uses Game Controller for the same. In medical science, Military and Video Gaming applications this is called Force Feedback. The VR technology also has applications in remote area communication in which it provides a Virtual presence of the user through the Virtual Artifact (VA). Thus the VR creates an environment similar to the real world in order to have a realistic feeling or Sci-fi.
The VRML (Virtual Reality Modeling Language) was first introduced in the year 1994. And at that time the main aim of this technology was the development of the “Virtual Words” without depending on the headsets. In the year of 1997, the development of industry standards for the web based 3D-Graphics the Web3D Consortium was founded. It was an Open-Source standard for the Web based Distribution of the VR items.
All of the today’s VR displays are based on the same technology as used in the Smartphones like gyroscopes and motion sensors for tracking head, hand, body positions. Independent production of the VR images and videos has a steep increase by the use of the Omnidirectional Camera which is also known as the 360-degrees Camera or the VR Cameras which can be used to record in all the directions. But the only drawback of this is that the captures images or the recorded videos are of low-resolutions and are highly compressed formats for online streaming.
In addition to this, the Photogrammetry is rapidly used to combine several High-Resolution Photographs for the creation of the more explaining 3D objects and the environment in Virtual Reality application area.
- Entertainment & Cinema:
The use of VR in Cinemas enables the audience to have a 360-degree view of the environment in each and every scene such as Fox Search Light Pictures and Sky bound.
Since 2015 VR has been installed on to the enormous number of Roller Coaster and Theme Parks.
- Healthcare & Clinical Therapies:
According to the recent studies from the Golden Sachs, healthcare area is one of the next markets that will use VR. Moreover, in some places, VR is already being used for the medical purposes.
- Anxiety Disorder Treatment:
The Virtual Reality Exposure Therapy is one of the forms of the exposure therapy for the treatment of the very normal disorder of Anxiety such as Post Traumatic Stress Disorder and Phoebes.
- Pain Management:
Here we apply a theory that may distract people reducing the experience of their pains according to the studies of the Immersive Virtual Reality.
- Education & Training:
VR provides a learning environment where the students can develop their skills without the real the fear of failing.
- Space Training:
For the span of past 20 years, NASA has been using this VR technology to train the astronauts while they are still residing on Earth. Some of these applications include: exposure to Zero Gravity Work Environment & training how to walk in the space.
