Virtual Reality (VR) is the term used to describe a three-dimensional, computer-generated environment which can be explored and interacted with by a person. VR implies a complete immersion experience that shuts out the physical world.
Augmented Reality (AR) is the result of using technology to superimpose information - sounds, images, and text - on the world we see. AR adds digital elements to a live view often by using the camera on a smartphone.
One of the issues of the modern education system is the limited ability to describe and exemplify complicated concepts and explain them in a more practical and accessible manner. The current way of explaining things is often a hit and miss affair where some students get the point while others are unable to do that duly. While this is a lesser challenge in humanitarian sciences, it becomes critical when it comes to physics, chemistry, and biology.
