Although they are not needed to enjoy all of the virtual reality content within each Experience Pack app, the physical reels provide an extra layer of interactivity called Augmented Reality (AR). It’s important to remember that having the physical reels is the only way to enjoy the Augmented Reality content. When you place a reel on the table and look at it through your View-Master® VR viewer, Augmented Reality icons will appear above the reel. These 3D icons serve as a menu – by selecting an icon with a click of the viewer’s lever, you can launch different experiences. In addition, some Experience Pack apps feature a library of Augmented Reality models that you can explore, but only if you have the physical reels to trigger them.
