Question

I’m programming an game in unity 3d, where I am mapping the kinect skeleton on a 3d model.

Now I have to check, if the player is leaning left or right… and here is my problem.

I’ve followed this site: http://blogs.msdn.com/b/mcsuksoldev/archive/2011/08/08/writing-a-gesture-service-with-the-kinect-for-windows-sdk.aspx

And now, I’m looking for a correct implementation of the lean-geasture.

Does anyone of you have an idea, how I can solve this problem? I have to make this gesture in some parts, so i can recognize a leaning. I’ve tried something like: if left shoulder.x < hips_left.x or left.shoulder.x > hips_left.x but that doesn’t work so good…

I really need your help 🙂

Answer 1

I would use someting like that perhaps combined with your idea

if(left.shoulder.y == right.shoulder.y){
    //No Direction
}else if(left.shoulder.y < right.shoulder.y){
    //leaning left
}else{
    //leaning right
}

Maybe you can use the head.x pos too

EDIT:

I’m not sure if this works perfect but in my tests it does work

if((left.shoulder.y + tollerance) >= right.shoulder.y && (left.shoulder.y - tollerance) <= right.shoulder.y){
    //No Direction
}else if(left.shoulder.y < right.shoulder.y){
    //leaning left
}else{
    //leaning right
}
