AR - Detect wrist without trackers - Watch app

Hello!

I'm looking for a solution. I'm aware of spatial / 3d tracking with programmes like Vuforia and 6D.ai

I want to build an app to demo watches on the wrist. However I don't want to use any trackers like in the example video. Is there a way to use marker-less tracking on my wrist to achieve the same experience (or better!).

I found this, marker-less tracking for the palm. However this uses depth sensors (and its a pretty old video). Is this possible for the wrists and for mobile?

Many thanks!

 

That's going to be really very hard. Especially with views like that shown in your first photo above... the arm there is just a sort of fleshy tube with no good features. A computer would have a hard time even guessing which way is the elbow end, and which the hand, without more to go on.
