AUGMENTED REALITY AND VIRTUAL REALITY

                  Although the term Augmented Reality (AR) and Virtual Reality (VR) are taken together here, there is
                  a distinct difference between the two.


                       Augmented Reality
                                                                                                Tech Fact
                  Augmented Reality is  the  blending  of Virtual Reality  and  real    Augment means to make
                  life. AR is  using  technology  to  superimpose  information  such    greater in size or amount.
                  as sounds, images and text on the real world that we can see.
                  Images are created by developers within applications that blend
                  in with content in the real world. AR users can interact with virtual content in the real world and can
                  also distinguish between virtual and real content.
                  AR is not a new technology. It was used in the display panels of fighter aircraft in the 1990s. The panel
                  displayed information about the altitude, direction and speed of the aircraft. A few years later the
                  panels displayed the target objects.

                  In 2009, Massachusetts Institute of Technology’s developed SixthSense.  It is a small device that is
                  worn like a pendant and combines the use of a camera, small projector, smartphone and mirror.
                  The projector and the camera are connected to the mobile device in the user’s pocket. The projector
                  projects the visual information on physical surfaces such as walls and other objects. The camera
                  recognizes and tracks the user’s hand gestures with the help of computer-vision techniques.

                                                       Google  Glass  created  in  2013 is  an example  of wearable  AR
                                                       interface. It helps the user to remain focussed on the work. It
                                                       displays on the user’s glass screen through a small projector.
                                                       It responds to voice commands to activate an application any
                                                       time.
