3D position supported on multi-camera Android phones

Recommended Posts


I have started to work on a game project involving hand-tracking for Android phones.

Here it is stated that any device with dual camera should be able to detect a 3D position of the hand.

However, I have tried some demo app with my Huawei P20 Pro and the 3D position of the hand seems to always be in the plane that is 25cm in front of the camera.

Is there something I might have done wrong, or 3D tracking is not yet possible on my phone?

Thanks! 😄

Hi @stefy_rzv

Although some newer phones have multiple cameras, hand tracking sdk only support one camera on Android phones. So it's always in 2d point mode for any Android phones.

The statement for 3D position is only valid for VR HMD.
