AR (Augmented Reality) has been experimented with for almost a decade. I recall in 2013 working over the summer at a app-development company that was playing with the idea of using smartphone cameras to overlay an animated character overtop a QR-code trading card. We’ve seen games like “Pokémon Go” in 2016 giving us cute little monsters seemingly in the same space as us. The applications have been simple so far, relying on simple overlay of CGI, but I suspect we will see greater innovation and growth in this field in the next 3-5 years. This is because both Apple and Google are starting to heavily promote the applications.
