I understand you need your face in the videos for the demos. But, want to mention that you should make sure your system works with your hands in your lap. As shown, the user is going to experience "gorilla arm" fatigue very quickly.

Good points, maybe a second camera (phone?) pointed downwards at the tabletop would be good for that. Then the user can rest their hands in a "normal" position.

Thank you for the feedback!
