Having issues using 3D in the dark

On lume pad 2 seem like you can’t use 3d in the dark because of eye tracking any why to fix that

It usually works for me as long as I put the screen on maximum brightness so it lights up your face. The camera does need to be able to see your face for Leia FaceTracking to work.

Ok got you

I don’t think it’s working very well for darker skin tones. I had to turn on my room light for it to go into 3d. Even at the max brightness, in a dark room, it keeps switching between 3d and 2d even when I’m not moving.

We have tested it extensively with darker skin tones. In fact, a large chunk of the Leia team have dark complexions.

High contrast between you and the wall/background behind you should ensure the tracking works perfectly. Leia FaceTracking is purely computer-vision based, so if your head/face/mouth/eyes are easily visible, that makes it work easier. It usually works well even if one thing isn’t visible (wearing a mask, wearing sunglasses, low contrast background, etc.) but if two things above are not visible, you can expect there to be issues, e.g. wearing a mask while also in the dark.

Still, we strongly recommend using the device in a lit room, which is a similar limitation to standalone VR headsets that use camera-based tracking.

Yeah it’s not a deal breaker but i wear glasses and am a darker complexion. It’s something I’ve grown accustomed to

Why is face detection required for 3d to be enabled?

This is the way the hardware was designed from the outset. Because of this, it offers a phenomenal 3D experience when it can track the user, but can not provide a consistently good experience when it can not, thus the device automatically drops to 2D view mode when a user isn’t detected.


Then, in dark conditions, the tablet should “shut off” the eye tracking but not the 3D effect, like the Hydrogen One, or the Rokit IO 3D pro. Both phones remain “the grid” without “auto adjustment” but with the 3D effect ON.

Unfortunately, the display design is completely different than those other devices and could not work properly in that scenario. Thus, it switches to 2D when a face is not detected.
