You missunderstood the topic!
Kinect is not a touchscreen tech., it recognises the gestures using the camera.
I'm just talking about gestures in the air, near and far in order to control the UI.
For example: I'm standing 10 feet away from my phone but the front camera is facing me. In order to change the song I'll wave my hand towards left to go back to previous song, towards right to go to next song, towards up to increase the volume, downwards to decrease the volume etc.
