步驟一:

先到120.125.70.53下載需要的檔案

步驟二:

假如processing內建沒有SimpleOpenNI

我們可以手動把SimpleOpenNI拉到libraries

Documents ->Processing -> libraries

打老鼠
一、偵測手的部分有一顆球

import SimpleOpenNI.*;

SimpleOpenNI openni;

void setup(){

  size(600,400);

   openni = new SimpleOpenNI(this);

   openni.enableRGB();

   openni.enableDepth();

   openni.enableUser();

}

void draw(){

   openni.update();

   background(255);

   image(openni.userImage(),0,0,300,200);

   int [] userList = openni.getUsers();

   PVector pos = new PVector(0,0,0);

   for(int userID : userList){

     openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_LEFT_HAND,pos);

   }

   ellipse(pos.x,pos.y,50,50);

   println(pos);

}

void onNewUser(SimpleOpenNI curContext,int userId){

  openni.startTrackingSkeleton(userId);

}


二、偵測雙手跟頭都有球

import SimpleOpenNI.*;
SimpleOpenNI openni;
void setup(){
  size(600,400);
   openni = new SimpleOpenNI(this);
   openni.enableRGB();
   openni.enableDepth();
   openni.enableUser();
}
void draw(){
   openni.update();
   background(255);
   image(openni.userImage(),0,0,640,480);
   PVector pos = new PVector(0,0,0);
   int [] userList = openni.getUsers();
   for(int userID : userList){
     openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_LEFT_HAND,pos);
     openni.convertRealWorldToProjective(pos,pos);
     fill(0,0,255);ellipse(pos.x,pos.y,50,50);
     openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_RIGHT_HAND,pos);
     openni.convertRealWorldToProjective(pos,pos);
     fill(255,0,0);ellipse(pos.x,pos.y,50,50);
     openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_HEAD,pos);
     openni.convertRealWorldToProjective(pos,pos);
     fill(255,255,0);ellipse(pos.x,pos.y,50,50);
   }
   ellipse(pos.x,pos.y,50,50);
   println(pos);
}
void onNewUser(SimpleOpenNI curContext,int userId){
  openni.startTrackingSkeleton(userId);

}

三、成功做出打地鼠了

import SimpleOpenNI.*;
SimpleOpenNI openni;
void setup(){
  size(600,400);
   openni = new SimpleOpenNI(this);
   openni.enableRGB();
   openni.enableDepth();
   openni.enableUser();
   imgBG=loadImage("bg.png");
}
PImage imgBG; 
void draw(){
   openni.update();
   background(255);
   image(imgBG,0,0,640,480);
   image(openni.userImage(),0,0,64,48);
   PVector pos = new PVector(0,0,0), hand1 =new PVector(0,0,0), hand2 = new PVector(0,0,0);
   int [] userList = openni.getUsers();
   for(int userID : userList){
     openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_LEFT_HAND,pos);
     openni.convertRealWorldToProjective(pos,pos);
     fill(0,0,255);ellipse(pos.x,pos.y,50,50); hand1.set(pos);hand1.z=0;
     fill(0,0,255);ellipse(pos.x/10,pos.y/10,5,5);
     openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_RIGHT_HAND,pos);
     openni.convertRealWorldToProjective(pos,pos);
     fill(255,0,0);ellipse(pos.x/10,pos.y/10,5,5);
     fill(255,0,0);ellipse(pos.x,pos.y,50,50); hand2.set(pos); hand2.z=0;
     //openni.getJointPositionSkeleton(userID,SimpleOpenNI.SKEL_HEAD,pos);
     //openni.convertRealWorldToProjective(pos,pos);
     //fill(255,255,0);ellipse(pos.x,pos.y,50,50);
   }
   PVector mouse1=new PVector(mouseX,mouseY,0);
   if(PVector.dist(mouse1,hand1)<100|| PVector.dist(mouse1,hand2)<100){
   ellipse(pos.x,pos.y,200,200);
   }
   //println(pos);
}
void onNewUser(SimpleOpenNI curContext,int userId){
  openni.startTrackingSkeleton(userId);

}
