设置用Kinect SDK控制的光标指针

Question

I'm developing a basic application to load and modify molecules and my main goal is to implement Kinect to do it. So far I've been able to do it with a mouse and I would like to do it with my right hand. After searching for a while I tried to define my cursor in a screen environment like if it would be done with a mouse (Input.mousePosition.x) substituting this for the hands coordinates (normalized for the screen dimensions). I can't make the cursor follow my hand, but I can make a game object follow any part of my body so my coordinates are being imported and when I debug my control variables they return a value contained in the screen dimensions. I guess my error is in OnGUI(). Can anybody help me.

Thanks in advance.

I have managed to find the sollution based on trial error attempts. :) Removed the extra code (commented code) to avoid misunderstandings. For whom it may interest:
