What's wrong with my Nyko Zoom and Kinect setup?

Ensure the lens of the Zoom tool is completely clean. With magnification, a small smudge is going to look a lot worse and affect the view so close to the Kinect. Alongside cleaning of the object, check how the add-on is sitting on the Kinect.

Is the housing too snug and holding the added lens at an angle to the body of the Kinect in a way so it is in fact occluding the camera's view?

After installing the zoom, I experienced ALL possible problems you could imagine that were posted here and in other blogs, ranging from not being able to find me to the jig dance and epileptic movements the avatar does when it does get around to seeing me).

Then I analyzed that this zoom was a reverse-telescope that makes me look smaller, and increases its view angle. So I did the following:

• I made sure there was no light at my back, even if it was in the ceiling several feet behind me.
• No lights to my sides which might be in the direct sight of the Kinect which now had an increased field of view.
• I made the light above me much brighter so that the Kinect can clearly see me.

Now the signal the Kinect senses (my body) is nice, clean, clear, and stable. No more jigs, epilepsy, and invisibility.

I hope I was able to help.
