Your facial hair, your glasses and your bangs may interfere with the Nintendo 3DS's ability to recognise your face, potentially bad news for the scruffy hipsters and the long-haired four-eyed nerds among us. That's just one of the (relatively minor) warnings included in English language 3DS instruction manual.
While not as entertaining as Japan's Nintendo 3DS instruction manual, the North American version that arrived at Kotaku today explains the potentially picky nature of the system's built-in cameras.
It doesn't like bangs covering your eyebrows, nor does it like it when you wear glasses, both key to facial recognition. The colour of your hair or beard may be an issue, as are "facial and hair decorations," like forehead tattoos, septum piercings and... I don't know... banana clips?
We're in the process of putting the Nintendo 3DS through its paces and will test our faces against its facial recognition software over the coming weeks.
