Virtual reality (VR) is a new computer technology which recreates a particular environment, actual or imagined, and simulates user’s physical existence and environment to enable user interaction. It is sometimes referred to as immersive multimedia or computer-simulated reality. This technology artificially produces sensory experience, which may include view, hearing, touch and smell.
In layman’s terms, Virtual Reality is an artificially made environment that is designed with software program and displayed to the user in such a way that the users suspends reality and accept it as the actual environment. In a computer, VR is mainly experienced via two of the five senses: sight and hearing.
The most basic form of virtual reality technology might be a 3-D image which can be explored interactively on a desktop or laptop, generally by using keys of the keyboard or the mouse so that the image content moves in different directions or zooms in or out. More advanced forms include such approaches as wrap-around display screens, real rooms augmented with wearable computer systems, and haptic devices that allows your sense feel the displayed images.
Uses of Virtual Reality technology
Virtual Reality is primarily used for the simulation of a real world environment for training and education purposes and the creation of an imagined environment for a video game or interactive story.
The VRML, Virtual Reality Modeling Language, permits the developer or creator to specify photos and also the rules for their display and interaction by making use of textual language instructions.
Virtual Reality in the Military
Military uses Virtual Reality for Flight and Battlefield simulation, Medic training, Virtual boot camp and Vehicle simulation.
Virtual Reality in Education
Education is another field where virtual reality can be used for teaching and learning purposes. The benefit of this is that it allows large groups of students to interact with each other and also within a 3-D environment.
As an example, students of astronomy can easily study the solar system and learn how it works through physical engagement with the objects. They can move planets from one place to another, observe the stars and monitor the progress of a comet. This technology also allows them to discover how abstract concepts work in a 3D environment which makes them simpler to fully grasp.
Uses of Virtual Reality in healthcare include robotic surgery and surgery simulation, phobia treatment, and training. It also enables healthcare specialists to gain new skills and also refreshing current ones in a risk-free environment.
Currently, Virtual Reality Technology is being used in many other sectors also.
