I want to do a simple kinect aplication in processing, I just want to when kinect detect a skeleton, show a simple jpeg image, just that. I wrote some code, all works but when someone appears in front of kinect, nothing happens, can anyone help me? This is my code:
import SimpleOpenNI.*;
SimpleOpenNI kinect;
void setup()
{
// Começar o evento
kinect = new SimpleOpenNI(this);
// Ativar o RGB
kinect.enableRGB();
background(200,0,0);
// Criar a janela do tamanho do dephMap
size(kinect.rgbWidth(), kinect.rgbHeight());
}
void draw()
{
// update da camera
kinect.update();
// mostrar o depthMap
image(kinect.rgbImage(),0,0);
// Definir quantidade de pessoas
int i;
for (i=1; i<=10; i++)
{
// Verificar presença da pessoa
if(kinect.isTrackingSkeleton(i))
{
mostrarImagem(); // draw the skeleton
}
}
}
// Mostrar a imagem
void mostrarImagem()
{
PImage img;
img = loadImage("proverbio1.jpg");
image(img, 0, 0);
}

You haven't setup the callbacks for OpenNI user events. Also if you simply want to display an image when someone is detected, you don't actually need to track the skeleton: simply use the scene image. You can get some information about the user's position without tracking the skeleton, like the user's centre of mass. This way you'd have a simpler and faster application if you don't actually need skeleton data.
Here a basic example:
import SimpleOpenNI.*;
SimpleOpenNI context;//OpenNI context
PVector pos = new PVector();//this will store the position of the user
int user;//this will keep track of the most recent user added
PImage sample;
void setup(){
size(640,480);
context = new SimpleOpenNI(this);//initialize
context.enableScene();//enable features we want to use
context.enableUser(SimpleOpenNI.SKEL_PROFILE_NONE);//enable user events, but no skeleton tracking, needed for the CoM functionality
sample = loadImage("proverbio1.jpg");
}
void draw(){
context.update();//update openni
image(context.sceneImage(),0,0);
if(user > 0){//if we have a user
context.getCoM(user,pos);//store that user's position
println("user " + user + " is at: " + pos);//print it in the console
image(sample,0,0);
}
}
//OpenNI basic user events
void onNewUser(int userId){
println("detected" + userId);
user = userId;
}
void onLostUser(int userId){
println("lost: " + userId);
user = 0;
}
You can see some handy SimpleOpenNI samples in this Kinect article which is part of a workshop I held last year.
