How to replace mouse input with kinect input with processing?

Can anyone advise me how to replace mouse input to kinect input using processing?
Instead of mouse tracking , I want to switch it to hand tracking using kinect . Do the same with hand gestures instead of finger movement on a laptop track pad.

The base code is Sine Wave Signal (File/Examples/minim/Sine Wave Signal) in processing.

import ddf.minim.*;

import ddf.minim.signals.*;

AudioPlayer player;

Minim minim;

AudioOutput out;

SineWave sine;

void setup()

{

size(1018, 400, P2D);



minim = new Minim(this);

// get a line out from Minim, default bufferSize is 1024, default sample rate is 44100, bit depth is 16

out = minim.getLineOut(Minim.STEREO);

// create a sine wave Oscillator, set to 440 Hz, at 0.5 amplitude, sample rate from line out

sine = new SineWave(60, 0.9, out.sampleRate());

// set the portamento speed on the oscillator to 200 milliseconds

sine.portamento(500);

// add the oscillator to the line out

out.addSignal(sine);



player = minim.loadFile("cello_08.mp3", 1048);

player.play();

}

void draw()

{

background(255);

stroke(0);

// draw the waveforms

for(int i = 0; i < out.bufferSize() - 1; i++)

{

float x1 = map(i, 0, out.bufferSize(), 0, width);

float x2 = map(i+1, 0, out.bufferSize(), 0, width);

float x3 = map(i+1, 0, out.bufferSize(), 0, width);

float x4 = map(i+1, 0, out.bufferSize(), 0, width);

line(x1, 50 + out.left.get(i)*50, x2, 50 + out.left.get(i+1)*50);

line(x1, 150 + out.right.get(i)*50, x2, 150 + player.left.get(i+1)*50);

line(x1, 250 + out.right.get(i)*50, x4, 250 + out.right.get(i+1)*50);

line(x1, 350 + out.right.get(i)*50, x2, 350 + out.right.get(i+1)*50);

}

}

void mouseMoved()

{

// with portamento on the frequency will change smoothly

float freq = map(mouseY, 0, height, 1500, 60);

sine.setFreq(freq);

// pan always changes smoothly to avoid crackles getting into the signal

// note that we could call setPan on out, instead of on sine

// this would sound the same, but the waveforms in out would not reflect the panning

float pan = map(mouseX, 0, width, -1, 1);

sine.setPan(pan);

}

void stop()

{

out.close();

minim.stop();



super.stop();

}
