Concept of educational technology  

people are mostly use technology in only entertainment. but actual this vr technology is very use to in animation word and many more field lets learn about us and grow your knowlagefor this technology...

What is Virtual Reality?

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 technology

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.  While they are fun for people in universities and big labs, consumer and industrial wearables are the wild west.
Concepts such Google Cardboard, Samsung GearVR and Epson Movario are leading the way but there are also players like Meta, Avegant Glyph, Daqri and Magic Leap 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.

   Microsoft HoloLens

Microsoft HoloLens is shaping up to be another formidable competitor in the Virtual Reality market. Unlike the Oculus Rift, Microsoft’s ambitious research teams are basing their display on holographic technology. While this lends itself to Augmented Reality (or, as Microsoft prefers to call it, “mixed reality”) more than VR, it’s clear that the display technology alone is meant to be a jumping-off point for virtual experiences to come.

   How Virtual Reality is being used today

 Unsurprisingly, the video games industry is one of the largest proponents of Virtual Reality. Support for the Oculus Rift headsets has already been jerry-rigged into games like Skyrim and Grand Theft Auto , but newer games like Elite: Dangerous come with headset support built right in. Many tried-and-true user interface metaphors in gaming have to be adjusted for VR (after all, who wants to have to pick items out of a menu that takes up your entire field of vision?), but the industry has been quick to adapt as the hardware for true Virtual Reality gaming has become more widely available. 

   Virtual Reality and data visualization

Scientific and engineering data visualization has benefited for years from Virtual Reality, although recent innovation in display technology has generated interest in everything from molecular visualization to architecture to weather models.

    Difference Between Virtual Reality & Augmented Reality?


How Virtual Reality Headsets Work (Inside)

 virtual reality head-mounted display (HMD) is a series of sensors, individual eye displays, lenses, and display screen(s), among other various components. The Ifixit Oculus Rift teardown offers an excellent step-by-step teardown and look inside of one of the most popular virtual reality headsets. Below we explore some of the key components inside of a virtual reality headset.


 Motion Tracking

Motion tracking is the way in which you view and interact with your own body (e.g. hands, movements, etc). One of the most natural motion-related acts is to want to be able to see your own hands (virtually) in front of you. To do this, virtual reality input accessories such as gloves can be used.  Other motion tracking devices such as wireless controllers, joysticks, treadmills, and motion platforms are now being used to supplement the headset and provide an even more immersive experience. Many of these input accessories utilize sensors to detect gestures such as pointing and waving. Virtual reality systems such as HTC’s Vive headset, utilize base stations to track the sensors from the headset and controllers.Motion tracking, in its simplest form, is the process of tracking the movement of an object within a piece of footage. Once you've collected this track data from the selected point, you then apply it to another element or object.

      Eye Tracking

 Eye tracking technology is still maturing, however, it may be one of the most important missing pieces to complete the virtual reality full immersion puzzle. Eye tracking involves tracking the human eyes via an infrared sensor that monitors your eye movement inside the headset. The main advantage to this type of tracking is that depth of field (i.e. distance) becomes much more realistic. In a virtual reality headset, the objects that our eyes focus on, need to look as life-like as possible. Without eye tracking, everything remains in focus as you move your eyes – but not your head – around a scene, thus causing a greater likeliness of simulation sickness.
