Our module for Kinect provides a simple solution for authoring gesture-based applications in Flash. Lately, we've been using it in conjunction with our other free Open Exhibits software modules. While the Kinect device itself doesn't have the necessary precision for use with every module, we have successfully paired it with our gigapixel image viewer, our VR image viewer, and with our Google Maps module.
Our free Kinect module works with Community Core Vision (CCV) software, an open source software package for computer vision. We've used this software in the past with various multitouch tables and other installations. Our Kinect module is a "directshow" source filter, a virtualized webcam device that reads data from the drivers released by OpenKinect.
The Kinect module and the others are all free and open on the Open Exhibits web. The Open Exhibits core software is free for students, educators, nonprofits, and museums. (Commercial users can download a free GestureWorks trial.) Add a $150 Kinect 3D Motion Controller and you have a very cheap and flexible authoring solution.
