Virtual Reality (VR)
Virtual Reality (VR) is the use of computer technology to create a simulated environment. Unlike traditional user interfaces, VR places the user inside an experience. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. The only limits to near-real VR experiences are the availability of content and cheap computing power. Virtual Reality’s most immediately-recognizable component is the head-mounted display (HMD).
Human beings are visual creatures, and display technology is often the single biggest difference between immersive Virtual Reality systems and traditional user interfaces. For instance, CAVE automatic virtual environments actively display virtual content onto room-sized screens. While they are fun for people in universities and big labs, consumer and industrial wearables are the wild west. With and software options, the future of wearables is unfolding but yet unknown. Concepts such as the HTC Vive Pro Eye, Oculus Quest and Playstation VR are leading the way, but there are also players like Google, Apple, Samsung, Lenovo and others who may surprise the industry with new levels of immersion and usability. Whomever comes out ahead, the simplicity of buying a helmet-sized device that can work in a living-room, office, or factory floor has made HMDs center stage when it comes to Virtual Reality technologies.
Types of Virtual Reality:
1. Non-immersive reality:
This type can be seen in the virtual reality flight simulator. It has a widescreen PC with a surround system and comes with other accessories like headphones, joysticks etc. It is non–immersive reality because the viewer does not get fully immersed in the reality this device produces. It won’t give a viewer the experience of being back in time or even ignite the person’s senses but one would still get a virtual reality experience.
2 Fully immersive reality:
One would experience full virtual experience because this type of virtual reality comes with a very powerful computer. This powerful computer must be able to detect sounds, sight, and even the slightest movement. It should be able to adjust the person’s experience. The viewer would have a head-mounted display (HMD) and would also put on sensory gloves. To achieve the fully immersed virtual reality, the device will make use of two monitors and a sound system.
3. Augmented reality:
Here one is experiencing a real world in such a way that it feels like a virtual reality experience. One can’t define it as an unreal experience but an experience of the reality around us. For instance, when a person visits an historical site on the internet, there are 3D mappings that would show the person landmarks, buildings, historical locations and other relevant information. One can move around areas in the computer to see fascinating historical sites using a smartphone.
Collaborative reality is usually in the form of virtual reality games and they are not fully immersive. This virtual reality gives the viewer an interactive experience and so one can even share their experience with other people in the virtual world.
Some Scientists have discovered ways to use virtual reality over the internet using the Virtual Reality Markup Language (VRML). This gives people an opportunity to discover new and interesting things the internet can offer. Also, people get to interact and have real experiences with their friends on social media.
1) Virtual reality creates a realistic world
2) It enables user to explore places.
3) Through Virtual Reality user can experiment with an artificial environment.
4) Virtual Reality make the education more easily and comfort.
1) The quipments used in virtual reality are very expensive.
2) It consists of complex technology.
3) In virtual reality environment we can’t move by our own like in the real world.
