We propose a novel augmented reality (AR) setup with an omnidirectional camera on a table top display. The table acts as a mirror on which real playing cards appear augmented with virtual elements. The omnidirectional camera captures and recognizes its surrounding based on a feature based image retrieval approach which achieves fast and scalable registration. It allows our system to superimpose virtual visual effects to the omnidirectional camera image. In our AR card game, users sit around a table top display and show a card to the other players. The system recognizes it and augments it with virtual elements in the omnidirectional image acting as a mirror. While playing the game, the users can interact with each other directly and through the display. Our setup is a new, simple, and natural approach to augmented reality. It opens new doors to traditional card games.
