Topic: Do you think the Switch might support face-tracking and 3D ?

The Switch doesn´t have a camera on the back, so augmented reality is likely not to be supported like on the 3DS.

Also there seems to be a single circular hole which might be a camera or sensor on the lover left side of the screen , which rules out a separate IR-source like in the New 3DS. Also, the placement of the sensor is on the bottom, so it might be more easily obscured than a placement on top.

Some rumors pointed to no camera in the portable unit.

Could it be a low light high fps sensor aimed at gestures and face-tracking ?

If it's a light sensor of any kind, it'll probably be used for automatic brightness settings and battery saving.

It looks a bit large for a basic ambient light sensor, but I guess it could be that they just made the hole that large for some manufacturing reason. The ambient light / proxy sensor on the iphone seems smaller, but it is hard to get a feel for scale.

I thought that was a mic.

I don´t think it´s a microphone because it´s embedded behind glass The speaker slots do have holes through the glass, and there´s something going on at the near the vents at the opposite side to the headphone jack. There seems to be two holes, but one might be an LED and the other image image artifact. ( Think Nintendo is holding back on something )

I doubt it's 3D...

it doesnt have a camera so no.

Yes, I guess 3D is a bit unlikely because it wouldn´t work when two people played on the same screen.
