Virtual Reality (VR) is a computer technology that replicates the real environment through generating real sounds, image and other sensation using Virtual reality headsets. VR simulates the
real existence of user in the realistic environment with 3D 360° environment.
A user can enjoy virtual reality by waring VR headsets goggles. Using this headset, a person can look around the artificial world.
Virtual reality is an artificial environment that is created with software and presented to the users in such a way that he user suspends belief and accepts it as a real environment. On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound.
The application area of Virtual Reality is increasing day by day. The Virtual Reality technology is being used and can be used in following fields.
1) Video Games :
In early mid 90's, the Different Virtual reality head mounted display (HMD) are released for video games. Wii Remote, Kinect, PlayStation Move are the example of narrow Virtual Reality for video games.
For example : you ware a data glove which has sensors attached to it. You ware this as part of driving game. These sensors record the way your hand moves as part of this game, say, when turning the steering wheel in a particular direction. These movements are fed back to a computer which then analyses the data and uses this to transform your actions into the appropriate responses on the screen.
2) Cinema and Entertainment :
So how is cinema in virtual reality different from classic cinema? Simplistically, a movie-watcher in classic cinema is merely an observer; we all know that feeling. In virtual reality, movie-watching is a 360-degree immersive experience where the viewer is at the center of the action. AS a scene unfolds, the viewer has the choice to look in whichever direction he or she wants and become absorbed in whatever part of the action they choose. Audiences can watch a film in virtual reality by strapping on a VR headset- Facebook's Oculus Rift, Samsung VR or Google cardboard are some of the better-known models.
3) HealthCare :
Healthcare is one of the biggest adopters of virtual reality which encompasses surgery simulation, phobia treatment, robotic surgery and skills training. Uses of virtual reality in healthcare can be found in the form of Human simulation software, Virtual reality diagnostics, Virtual robotic surgery, etc.
One example of this is the HumanSim system which enables doctors, nurses and other medical personnel to interact with others in an interactive environment. They engage in training scenarios in which they have to interact with a patient but within a 3D environment only.
Virtual reality is often used as a diagnostic tool in that it enables doctors to arrive at a diagnosis in conjunction with other method such as MRI scans.
4) Education and Training :
Several characteristics of VR provide an opportunity to boost student engagement. As a hands-on, interactive, immersive experience, it provides a novel way of learning for students, delivering powerful new experiences they may not have encountered before. For exemple, Google Expeditions allows teachers to transport students to virtual field trips to Mars, the bottom of the ocean, and many other settings, which can spark new interest in subject matter, provide a shared experience for better classroom discussion, and improve overall engagement.
Similarly, Virtual reality is used to train the participators to developed their skills on consequence of falling without real environment. Similarly it is used in education training, military training, space training etc.
5) Engineering :
Virtual Reality is used to developed 3D Computer-aided design in the field of Engineering. VR for engineering is also reaching new levels of utility and access. The ability to install full-room configurations like a cave automatic virtual environment (CAVE) at a reasonable cost means that these systems are being found in more and more facilities, for uses like walkthroughs and presentations as well as collaboration during the development phase. What's more, virtual reality headsets are providing ever more useful to engineers working with individual components, parts and product concepts. It helps engineering in the field of designing, manufacturing, testing ,collaboration, presentation, modeling, etc.
6) Sport
Virtual Reality is used as a training aid in many sports such as golf, athletics, skiing, cycling etc. It is used as an aid to measuring athletic performance as well as analyzing technique and is designed to help with both of these. It also used in clothing/equipment design and as part of the drive to improve the audience's experience.
For example, a golfer looking to improve their swing or a track cyclist wanting to go faster in the individual pursuit. Three dimensional systems can pinpoint aspects of an athlete's performance which require changing, for example, their biomechanics or technique.
Virtual reality has also been used to improve the audience's experience of a sproting event, Some systems allow the audience to walkthrough a stadium or other sporting location, which helps them when purchasing a ticket to an event.
In final words, applications of Virtual reality are even more field like Marketing, Agricultural, Fine arts etc. All in one the Virtual Reality is the most useful technology in every field of our life.
