Hi @emanuelmaia, when you are seeing your hands in the visualiser this is expected behaviour and normal that your right hand appears on the left and your left hand is on the right within this screen. Because the camera is looking up at your hand, not down at it, it sees your left hand as being on the right. In any application, that hand would be interpreted as being your left hand as you'd expect it to.
Please note that for the hand tracking to work correctly the hands must enter the frame of the image from the bottom of the image. The camera orientation reversal is to allow you to reverse the hardware and the reorient the camera to match.
