Cardboard?Gear VR hand tracking ?

Hi All,
About a month ago, there was a post about a Gear/Cardboard hand tracking sdk via the camera.
Looked pretty cool, had a video showing someone picking up a cube in 3D space.
I can’t find it anymore…help!

Anybody know where it went?

Best,
Andy

Hmm, interesting. I would think this would be fairly difficult to do, without specialized types of camera (such as what Kinect uses), but I suppose it could be approximated (based on edge/shadow recognition and scale/size changes to determine depth of hand in z-axis)

Where did you see it? On this forum?
