Augmented reality systems show virtual objects in the real world – like cat ears and whiskers on a Snapchat selfie, or how well a particular chair might fit in a room. The first big break for AR was the “Pokémon GO” game, released in 2016 with a feature that let players see virtual Pokémon standing in front of them, ready to be captured and played with. Now, technology companies like Microsoft and Mozilla – the company behind the Firefox browser – and even retail businesses like IKEA and Lego are exploring the potential of AR.
