hand tracking

kblalwani

I am using the AveragePointTracking example on the Open Kinect library, but can't figure out how to make an image appear on the screen when you move your hand on a certain location on the screen. I tried if statements with the location but doesn't work either.

     import org.openkinect.*;
     import org.openkinect.processing.*;

    // Showing how we can farm all the kinect stuff out to a separate class
    KinectTracker tracker;
    // Kinect Library object
     Kinect kinect;

     void setup() {
     size(640,520);
      kinect = new Kinect(this);
       tracker = new KinectTracker();
        }

      void draw() {
      background(255);

     // Run the tracking analysis
     tracker.track();
      // Show the image
      tracker.display();

     // Let's draw the raw location
     PVector v1 = tracker.getPos();
     fill(50,100,250,200);
     noStroke();
      ellipse(v1.x,v1.y,20,20);

    // Let's draw the "lerped" location
    PVector v2 = tracker.getLerpedPos();
    fill(100,250,50,200);
     noStroke();
     ellipse(v2.x,v2.y,20,20);

    // Display some info
    int t = tracker.getThreshold();
     fill(0);
    text("threshold: " + t + "    " +  "framerate: " + (int)frameRate + "    " + "UP increase threshold, DOWN decrease           threshold",10,500);
     }

  void keyPressed() {
   int t = tracker.getThreshold();
   if (key == CODED) {
    if (keyCode == UP) {
  t+=5;
  tracker.setThreshold(t);
  } 
 else if (keyCode == DOWN) {
  t-=5;
  tracker.setThreshold(t);
 }

} }

void stop() { tracker.quit(); super.stop(); }

Some comments

1. Where is the hand tracking coordinate ? I can't see anything related to hand tracker.
2. What does this "tracker" do? (My bad, I am not familier with library but logic could be the same)
3. Can you post your hand tracking code if you have?
