                                              Disney Research developed a coloring book with AR. After the
                                              user colors in a character in the book, he / she launches the app
                                              on the device. The app uses the camera to detect the character
                                              that was colored. The app also uses AR to recreate the character
                                              in a 3D form on the screen.

            Virtual Reality

            In Virtual Reality, we create a virtual world that users can interact with. In this world, the user
            cannot easily distinguish between what is real and what is virtual.
            In both VR/AR, people must wear HMD (Head Mounted
            Displays) or  a  VR Headset like Oculus Rift or  Google
            Cardboard.  The  headset  has  two  small video  display
            screens  one  for  each  eye.  This creates  the  sense of
            three-dimension.  You  can  also wear  headphones and
            gloves to  experience  VR  and  AR.  The  headphones  play
            stereophonic  sound or even  3-D sound so that  you can
            feel that you are hearing sounds not only near the ears but
            also in various places all around you. The gloves have sensors to collect data about your hand
            movements. This equipment and the software gives you interactive sensory feelings similar to
            real-world experiences.

            Both AR and VR provide a total immersive experience to the user. These technologies find the
            greatest use in entertainment, sports/gaming, close interactive eye to eye communication and
            aided shopping experiences. Imagine sitting at home and browsing through a store in London
            where you can see and feel the merchandise you wish to buy. This technology is also used in
            education.  Imagine being a live participant  in a historical battle or a student of anatomy in
            medical school. You can really feel the battle or touch the organs.
            We must remember that the journey of VR started in the 90’s with the Nintendo Boy but it really
            did not catch on. Now the case seems different as the means of experiencing AR/VR has become
            less expensive. Also, there is a lot more on offer and we are all connected all the time at least via

            our smartphones.

                                                                     Latest Technological Developments       59
