title: How to detect a Triangle gesture with kinect?
body: <p>I am trying to implement a gesture recognition system which interprets the geometric gestures user makes and draws it on screen, </p>
  
  <p>I have some idea of how circle can be recognized, however I have no clue how to get started with triangle recognition.</p>
  
  <p>The data I have is X and Y coordinates of all points the gesture passed through. I get this data by tracking right hand. </p>
  
  <p>I found something online called Hough Transform, which is used for detecting lines but I am not sure whether it will work for discrete collections of points.</p>
  
  <p>Any ideas folks?</p>
