Virtual Reality
Virtual reality (VR) typically refers to computer technologies that use software to generate realistic images, sounds and other sensations that replicate a real environment (or create an imaginary setting), and simulate a user's physical presence in this environment, by enabling the user to interact with this space and any objects depicted therein using specialised display screens or projectors and other devices. A person using virtual reality equipment is typically able to "look around" the artificial world, move about in it and interact with features or items that are depicted on a screen or in goggles. Virtual realities artificially create sensory experiences, which can include sight, touch, hearing, and, less commonly, smell.Most 2016-era virtual realities are displayed either on a computer monitor a projector screen, or with a virtual reality headset.
USES OF VIRTUAL REALITY
1.Education and training
Research says that learning through Virtual Reality enhances learning.VR is used by trainers to provide learners with a virtual environment where they can develop their skills without the real-world consequences of failing.Thomas A Furness III was one of the first to develop the use of VR for military training when, in 1982, he presented the Air Force with his first working model of a virtual flight simulator.
2.Video games
Virtual reality is most commonly used in video games.Virtual Reality uses graphics, sound and input technology in video games.These included the Virtual Boy , the iGlasses ,the Cybermaxx ,and the VFX1 Headgear.Modern examples of narrow VR for gaming include the Wii Remote ,the Kinect, and the Play station move or Play station eye all of which track and send motion input of the players to the game console somewhat accurately.
3.Engineering
Virtual reality has been used in automotive, aerospace, and ground transportation original equipment manufacturers (OEMs) in their product engineering and manufacturing engineering . Virtual reality adds more dimensions to virtual prototyping , product building, assembly, service, performance use-cases. This enables engineers from different disciplines to view their design as its final product. Engineers can view the virtual bridge, building or other structure from any angle. As well, some computer models allow engineers to test their structure's resistance to winds, weight, and other elements.
4.Theme parks
Since 2015, virtual reality has been installed onto a number of roller coasters. There are virtual reality rides that put the individual in the real situation.The individual feels like he is really inside the game screen.One can can see, smell and even touch what is happening in the game.
5.Marketing
Virtual Reality has the potential to completely replace many forms of digital marketing.[80] Marketing strategies in small and middle sized enterprises, ever more frequently include virtual reality in their ad concepts.Virtual Reality presents a unique opportunity for advertisers to reach a completely immersed audience
CONCERNS AND CHALLENGES:
There are certain health and safety considerations of virtual reality.Virtual reality sickness (also known as cyber sickness) occurs when a person's exposure to a virtual environment causes symptoms like general discomfort, headache, stomach awareness, nausea, vomiting, pallor, sweating, fatigue, drowsiness, disorientation, apathy and postural instability. Users might get completely involved in the virtual environment that they might forget their actual surroundings.
