this project is based on tf-lite-unity-sample
In the sample scene you'll find a game object named BlazePose that has the main script attached to it.
The Custom Camera Name field is used to specify a camera name - leave this blank for it to pick up the default camera.
If you want to use the tablet you can tick Use Front Facing Camera if you want to use the front facing camera.
The script will give you access to all body landmarks being tracked in real time using worldJoins and to get you started I've already extracted left and right hand positions as game objects leftHand and rightHand .
For debugging you can tick DrawSitckFigure for it to show the blue outline (as with the video I shared above) or enable the Canvas game object to see the actual camera feed.
