Although augmented reality and virtual reality have been in use for quite a few years it is only now that it is attracting media attention. The difference between these two has been a point of confusion with both technologies promising immense growth. But first of all, we should be clear in our minds as to what both these technologies stand for
Virtual Reality (VR)
Virtual Reality is an advanced but artificial computer simulated technology that has the ability to recreate an environment whether real or imaginary. It makes the user experience the replicated environment as real and firsthand by stimulating their sight, smell, touch and hearing. The user can enter the environment by wearing special VR headsets and experience the situations eg. Creating and enhancing an experience while playing video and computer games or watching 3D movies. Another example is enhancing training in real life by creation of a reality simulation like pilots using flight simulators.
Virtual reality can be attained through VRML (Virtual Reality Modeling Language), a code language that is used to construct a series of images specifying the possible types of interactions for them.
Augmented Reality (AR)
Augmented reality is a technology whereby elements of real environments are augmented or magnified by computer-generated sensors like video, graphics, sounds or GPS data. It is basically blending of computer-generated enhancements onto an already existing reality to make it more significant enhancing one another. AR has been developed into apps and is being used on mobile devices blending digital components into the real world in a way that besides enhancing one another they can also be told apart.
