Top Trumps 3D Augmented Reality card game. As a supporting element to their decks of cards, Top Trumps introduced a series of special packs with augmented reality markers printed on the cards, providing a new interactive experience. Upon installing the software and showing the initial card to the webcam, the user is asked a series of questions, the answers for which are other cards in the deck. Upon completing the questions a special stage is reached.
In the Ben 10 Alien Force pack, this allowed the user to print out a special symbol, which once cut out could be folded around the wrist as a watch, mimicking Ben’s watch. This watch would give a holographic projection of various Aliens and readouts about their abilites.
