What is the difference between Augmented Reality and virtual reality

Virtual reality: Ever flown an aeroplane or really wanted to? No, because you don’t have the skill set required? Heck! That shouldn’t be a problem anymore! With virtual reality, you can almost literally be the pilot of your own plane! Virtual reality is an artificial three-dimensional environment created for humans. The person becomes a part of the world of virtual reality and is able to manipulate things in his surroundings and interact with that reality. An entirely new artificial environment is created electronically (most certainly not a new physical environment) which seems almost very real, and the user is placed in it.

The term virtual reality was first termed by Jaron Lanier, one of the modern pioneers of the field. The widespread applications of VR and AR are an indication of the future expansion of these fields. With Top btech Colleges In India focusing and researching on it, there surely are many more surprises in store!

Augmented reality : 

Haven’t you come across those times when you really want to know how a chair that you see on pepper fry would look in your hall and not on their website? With augmented reality, this is possible. Augmented reality is a fascinating field which combines and superimposes computer generated images with user’s digital environment in real time. Unlike virtual reality, which creates a totally artificial environment, augmented reality uses the existing environment and overlays new information on top of it. The term ‘augmented reality’ was first coined by Thomas Caudell, a Boeing researcher.


One of the fields where Virtual reality has been implemented is in the military. VR is used to stimulate a battlefield so that the soldiers can be trained without being hurt or killed. AR programs are also used by the military (machine vision). The Heads-Up Display (HUD) is the typical example of AR usage in military. VR is used also in buildings. The basic plan of the building is first outlined and then builders can get a preview of how it may look using VR. A lot of cinemas are using VR these days.

Devices to be worn on the head are given to viewers and the movie is played. You could see how life would be as a doctor after your NEET 2018 

exams! Another important application of VR is in the field of medicine. Doctors/surgeons use VR to determine the best incision position and angle while removing tumours etc. AR is also used in the practice of medicine. Visualizations aid in explaining to patients the complex conditions that exist. This technology is often combined with MRIs and X-ray systems. Neurosurgery is greatly affected by AR and VR.

VR is implemented in automobile manufacturing, aviation, museums and also in the field of education. Typical applications of AR include primarily the navigation systems or GPS to locate and guide the user to the required destination. Today, Google glass and heads-up displays in car windshields are the most well-known consumer AR products. AR is popularly used in gaming. With recent advances in gaming technology and computational power the usage of AR for growing exponentially. One of the earliest applications of AR was the yellow first down line printed on the football field in the game, NFL.
