Hi @soypablete, what you are seeing here is the correct behaviour as the Leap Motion controller is looking up at the underside of your hands and the visualiser is oriented from the perspective of the camera. If you enable images within the control panel you will see this camera image in the visualiser with the tracked hand overlaid on it.
The option to reverse the orientation reverses the entire camera image from the device and will break the hand tracking unless you reverse the device as well as the hands need to enter the image from the bottom of the frame in order to be correctly identified and tracked.
I hope this helps, if you can let me know a bit more about what you are trying to achieve with the visualiser I will be happy to advise further?
