1.偵測人的頭部,然後會有一顆相對應的白色球
import SimpleOpenNI.*;
SimpleOpenNI openni;
void setup(){
  size(600,400);
  openni = new SimpleOpenNI(this);
  openni.enableRGB();
  openni.enableDepth();
  openni.enableUser();
}
void draw(){
  openni.update();
  image(openni.userImage(),0,0,600,400);
  for(int userId : openni.getUsers()){
    PVector pos = new PVector(0,0,0);
    float confidence = openni.getJointPositionSkeleton(
      userId,SimpleOpenNI.SKEL_HEAD,pos);
     ellipse(pos.x,pos.y,50,50);
     println(pos);
    }
  }
  void onNewUser(SimpleOpenNI openni ,int userId){
    openni.startTrackingSkeleton(userId);
  }

2.修正白球的BUG,和頭上下移動變成一致
import SimpleOpenNI.*;
SimpleOpenNI openni;
void setup(){
  size(600,400);
  openni = new SimpleOpenNI(this);
  openni.enableRGB();
  openni.enableDepth();
  openni.enableUser();
}
float Xpos(PVector pos){
  return height/2 + pos.x*500/pos.z;
}
float Ypos(PVector pos){
  return height/2 - pos.y*500/pos.z;
}

void draw(){
  openni.update();
  image(openni.userImage(),0,0,600,400);
  for(int userId : openni.getUsers()){
    PVector pos = new PVector(0,0,0);
    float confidence = openni.getJointPositionSkeleton(
      userId,SimpleOpenNI.SKEL_LEFT_FOOT,pos);
     ellipse(Xpos(pos),Ypos(pos),50,50);
     println(pos);
    }
  }
  void onNewUser(SimpleOpenNI openni ,int userId){
    openni.startTrackingSkeleton(userId);
  }




3.腳踢動作會出現紅色透明背景
import SimpleOpenNI.*;
SimpleOpenNI openni;
void setup(){
  size(600,400);
  openni = new SimpleOpenNI(this);
  openni.enableRGB();
  openni.enableDepth();
  openni.enableUser();
}
float Xpos(PVector pos){
  return height/2 + pos.x*500/pos.z;
}
float Ypos(PVector pos){
  return height/2 - pos.y*500/pos.z;
}

void draw(){
  openni.update();
  image(openni.userImage(),0,0,600,400);
  for(int userId : openni.getUsers()){
    PVector pos = new PVector(0,0,0) , pos1=new PVector(0,0,0),pos2=new PVector(0,0,0);
   float confidence;
   confidence = openni.getJointPositionSkeleton(
      userId,SimpleOpenNI.SKEL_LEFT_FOOT,pos1);
   ellipse(Xpos(pos1),Ypos(pos1),50,50);
   print("Foot:"+confidence);
   confidence = openni.getJointPositionSkeleton(
      userId,SimpleOpenNI.SKEL_HEAD,pos);
       ellipse(Xpos(pos),Ypos(pos),50,50);
   confidence = openni.getJointPositionSkeleton(
      userId,SimpleOpenNI.SKEL_LEFT_FOOT,pos1);
   ellipse(Xpos(pos2),Ypos(pos2),50,50);
   println(abs(pos1.y-pos2.y));
   if(confidence>0.6 && abs(pos1.y-pos2.y)>100) {fill(255,0,0,128); rect(0,0,600,400);}
    }
  }
  void onNewUser(SimpleOpenNI openni ,int userId){
    openni.startTrackingSkeleton(userId);
  }
