Nintendo’s latest handheld system, the 3DS will launch with six augmented reality cards featuring characters from Nintendo, one of which will be Metroid protagonist Samus Aran! The augmented reality cards work by placing them face down on a flat surface and pointing the 3DS camera at them in order to detect what is on the card and allows you to interact with the card in a similar way to how the Eye Toy from Sony works.
The six cards bundled with the system feature classic characters Mario, Link, Kirby, Pikmin, Question mark block and Samus. It is not yet known what sort of features these six cards will bring but as soon as we know we will update you with the information.
UPDATE: According to Wired the Nintendo character AR cards mentioned are for an AR game called “Star Pics” which is played by placing one of the cards on a table and a 3D model of that character will display on your 3DS. You can then move the 3DS around the card and take pictures of the model from different angles and save them. This isn’t exactly a game but it’s still a nice little feature that you may be able to have fun with.
