Why the next Nintendo console could be - "Wii 3D"

So how does the new 3D work? If it does require double the refresh rate - how do the glasses separate the 2 halves?

The glasses are actually a pair of LCD screens (1 pixel per eye). They alternately light up to block the current frame from one of the eyes, in order to let each eye only see even/odd frames.

The glasses synchronize with the TV via an infrared signal (emitter needed, if not included in TV) in order to know the frame timing.

They're called LCD shutter glasses.
