Virtual Reality vs. Augmented Reality: What’s the difference?
Virtual Reality and Augmented Reality are words we see thrown around a lot, and there may be a bit of confusion as to what makes these technologies any different. They are both immersive technologies which integrate virtual content with the physical environment.

However they have a number of distinct characteristics that make them different. We’ll be discussing those.
Virtual reality essentially takes the use of computer technology to create a simulated environment in which users are completely immersed. This is one of the most well-known immersive technologies. You can experience VR by using a special VR viewer such as the Oculus Rift, Google Cardboard or Samsung Gear VR.
With VR you can actually move around in the immersive environment and look in every direction as if you were physically present there. VRML (Virtual Reality Modeling Language) is used to create 3-dimensional interactive vector graphics which the user can interact with.

While VR was first commonly used for gaming and entertainment purposes, it is now also being utilized in various organizations/industries such as military, healthcare, education etc. And while the benefits are numerous there are a few reported health hazards. For example, people report headaches, eye strain, dizziness and nausea after using VR headsets.
Where virtual reality create an entirely immersive environment, augmented reality enhances the real world with images, text and other virtual information through devices such as smartphones, tablets and AR glasses. AR is basically technology that overlays digital information on the real world. One example is AR apps on your smartphone camera which can add images/text onto your camera view of the real world.

Popular apps which use augmented reality include Snapchat and Pokémon GO which gained large traction back in 2016. A number of tech companies such as Facebook and Samsung are also looking into developing AR.
Major Differences between the two

Virtual reality creates an entirely new virtual world whereas augmented reality is a mix of the real and virtual world.
You can easily distinguish between the real world elements and the virtual elements using AR whereas in VR that is highly unlikely.
They differ basically in the user’s ‘presence’. By using VR the user disconnects from the world around him whereas AR simply alters the current reality for the user.
