Joy-Con IR camera has another use?

If you are holding the controller the way it's supposed to be held, I think the motion sensors are enough to determine which is down. Technology is improving so I'm sure they found a work around for the sensor bar but using the IR camera for this would be a bit odd in my opinion

Probably there for whatever handwaving features Nintendo wants to add to their games, but I don't see this being used much :/

I always asking myself if Nintendo actually do have a plan on hiw to use these techs efficiently. Sometimes they add some feature, but let them die out like the AR of the 3DS.

 

So either Nintendo has a plan for that IR sensor or they just put it in for 3rd parties for fun. Needless to say, that it increases the cost of the devices.
