PushSquare: "Contrary to popular belief, AR in video games did not start with the Nintendo 3DS. We know Nintendo fans like to believe their favourite video game manufacturer is responsible for every invention in the video game space, but on this occasion they are wrong. Sony, in fact, has been dabbling with AR for years.
Overnight the company announced SmartAR, a technology that's important for one major reason: no more cards. If you think of EyePet on the PlayStation 3, you had to place a very specific card on the carpet for the EyePet to appear. SmartAR will work with a variety of objects and sources, adding "new value to various services and business applications such as advertising and games"."
