The sensor is attached to a camera and another sensor is in my hand.
Just Test !!
I tried to implement Digits system of MS (http://www.youtube.com/watch?v=Tm2IuV...), freehand 3D interactions using a wrist-worn gloveless sensor. This system uses IR laser lines, IR diffuse illuminator, and a IR camera. Instead of the use of them, I used the intel's gesture camera to simplify the system. But, the camera with low FoV cannot capture five fingers well. The thumb sometimes occludes the other fingers.
