First time I am using Kinect sensor and tried processing libraries for kinect, got it work with processing and tried some example and also wrote some simple application for fun :) . 

My question is .. 

I want to detect if any object has been touched by me within the real space (like a 3D touch but in real space). Let me give you an example, suppose I have multiple objects like TV, table, chairs  and some other things inside the room and when I touch any of them it should detect that it has been touched.

I was thinking if kinect can measure dynamic depth of my finger, finger motion in 3D space and when I touche any surface it should detect the interference of two planes. But the problem can be (not sure) if it can create multiple planes for different objects and also detects the interference of my finger plane (3D coordinate of finger) with other planes.  

If it can't possible with processing then forget about processing, can we do it with other language/platforms? 

I can also use two kinect sensors if requires.

I know, kinect can measure depths but can it measure multiple depth with touch ? 

(  Please I help me I dont have much time. I need it for my project )
