Wide-Area Augmented Reality allows the users to set up their own environments for the characters to interact in. Around the one minute mark in the following video, a little dog runs around an obstacle course that the user was still rearranging. The virtual creature that seems to freely roam in the augmented environment of trees (which are stationary in the position of their cards) is what makes this demo the most appealing to me. It makes me think that a similar augmented reality experience could be used by the military to train their soldiers who would wear augmented reality glasses as they crawl, jump, and run through a bigger, more complicated obstacle course. A simpler use of wide-area augmented reality could be to simulate the behaviors of other pets or small wild creatures like butterflies for children to learn about them in great detail.
