Nintendo has a new promotional video that shows off the Nintendo 3DS's various functions like Tag Mode, Mii Studio and the portable's augmented reality capability.

Since it's hard to show 3D on a 2D screen, Nintendo has packed this promotion video with all the extras that its new portable is able to do. Tag Mode enables Nintendo 3DS portables to stay in constant contact with nearby 3DS handhelds and exchange data. The Mii Studio feature can automatically make Miis based on real photos, while the AR function lets players enjoy augmented reality with their Nintendo 3DS and AR cards.

No doubt the AR function will come in useful for Nintendo's Augmented Reality Games as well as third-party titles.
