I have had sunlight screw up the wii-mote as well before. So yes Sunlight has an effect on camera as well bad glare on TV screens.

Sunlight interferes with the Wii's Infrared, just as it can affect any other infrared remote control.

 

i believe natal works with infrared technology too, i wonder if that could become a subject in the future as well.

So Natal is "based" upon IR tech, did not know that.  Either way movement can be miss read with just a varying difference in light sources.

In fact Natal works with hybrid technology where IR and normal camera based motion tracking is processed with Natals CPU to "skeleton" with several tracking points. Heavy IR source like studio lamps or direct sun light would cause problems for more precise IR camera, but normal camera would still work.
