Can we make it happen? Modeling a Gesture She wants the screen to respond to a gesture vocabulary that’s intuitive, even personal, and so we’ve decided that the system should be “trainable” and make use of the X-, Y- and Z-axis. The ”operating room” scenario is fairly common “Kinect hacks” fare: Imagine a surgeon who wants to manipulate data and images on a screen without leaving the operating table, touching foreign objects, etc. To keep the exercise tethered to reality, let’s posit a hypothetical application.
Kinect Gesture Recognition Example Application Last time I checked, you can’t find fleshed-out examples of HMM-based gesture recognition on the open Web. My goal is simply to share a working proof-of-concept in the hope that it helps someone.

That said, I do not cover specifically how to get this point data yourself from Kinect/OpenNI (though that is covered in lots of places, so check the forums), and I do not describe how to implement gesture recognition in real time (though I can assure you that it’s do-able by extending the techniques described herein- we’ve done it in Sensecast). I’ve cobbled together some code for applying this technique to 3D point data in Octave, and I’ve included some gesture data (including training and test sets) gathered using a Kinect and OpenNI’s hand-tracking capability as described below.

What You Need to ProceedĪll you need to try out this basic HMM-based gesture recognition technique for yourself is a working install of GNU Octave (which means Matlab should more or less work, as well). But in this article, we’ll simplify the task, use some pre-existing machinery as a subsystem for our code, and attempt to perform–or at least understand–simple gesture recognition on data from the Kinect. The answer can quickly lead us into deep computer vision and machine learning territory that will send noobs packing. Now, suppose we want to do this kind of analysis ourselves.

Though depth cameras are not exclusive to Microsoft (and, in fact, the Kinect’s hardware design is licensed from the Israeli company, PrimeSense), Microsoft’s novel use of the device as a game controller is driven by the company’s own software for analyzing its 3D data, including proprietary algorithms for feature selection, scene analysis, motion tracking, skeletal tracking and gesture recognition. Microsoft’s Kinect sensor is the first large-scale, commercial release of a depth camera device-a camera that can see in 3D. I also worked with my friend Frederik Lang on the material presented here, but the shortcomings remain all my own. Note: The precious little I know about machine learning I learned from the brilliant Frank Wood, whose talk at the Machine Learning meetup inspired me to finally put together this post.
