What is VR and AR ?

What is VR ? 

VR full form is Virtual Reality.  

Virtual reality (VR) is a simulated experience of virtual world that employs 3D visulaization to near-eye displays to give the generating a three-dimensional image which appears to surround the user feel of a virtual world. 

Understanding of Virtual Reality

Application of virtual reality is includes video games, movie, 3D movie, 360 degree videos and images, study and many more. Now a days, Normal virtual reality systems uses virtual reality headsets or multi-projected environments to virtualize realistic games, images, sounds and other sensations that simulate a user's physical presence in a virtual environment like real. 

A person using virtual reality devices is capable to watch around the virtual and imaginational world, move around in it, and interact with virtual features or things. 

The feel is normally designed by VR (virtual reality) headsets and devices composed of a headset display with a small screen in front of user eyes.User can also be created through specially designed rooms with multiple big screens. Virtual reality typically includes auditory and video feedback, but may also allow other types of sensory and force feedback through haptic feedback technology. 

Short History of  (VR) Virtual Reality 

  • The meaning of virtual reality is that "feel real but not actually in real world only visualization that feel realistic experience" since the mid-1400s as per wikipedia but in computer sense means that totally created by software since 1959. 

Future prediction of VR (Virtual Reality) 

Since 2017, great strides have been made in the integration of virtual reality and cognitive behavioral therapy, with a focus on how to tailor the experience to each individual patient. 

With the COVID-19 restrictions in 2020, VR is experiencing an huge rise. As per to Grand View Research, the global Virtual Reality  market will grow to 62.1 billion dollars in 2027 

Present the post-pandemic era,AR(augmented reality) and VR(Virtual reality) technologies have created a new way that may impress the future of professtional safety training and improvement

What is AR ?  

AR full form is Augmented Reality.    

AR (Augmented reality) is an improved version of the real world that is proven through the use of digital visual parts, sound, or other sensory stimulus and delivered threw technology. It is a rising trend among industries involved in computing and business applications in particular. 

Understanding of Augmented Reality 

Some times we are using this types of system in real world like in snapchat we are using image filter this is the faced example as user that means that augmented reality is treated like virtual elements in the real spaces. If we are take another example is that in many mobile application we can put a dog in the table using camera in this dog is example of augmented reality and table is real entity this is the clear cut example of augmented reality system. 

Short History of  (AR) Augmented Reality 

  • In 1901 the L. Frank Baum was an author his mentioned that virtual element that overlays nnto real entity. 
  • In between 1957–62 Morton Heilig was a cinematographer his created simulator and it's name was Sensorama with visual, sound. vibration and smell. 
  • In present, in 2019 Microsoft announced Hololens 2 with noteworthy progressin terms of field of view and ergonomics.
