KinectTouch: accuracy test for a very low-cost 2.5D multitouch tracking system

We present a simple solution for a touch detection system on any display at a very low cost. By using a Microsoft Kinect, we can detect fingers and objects on and above a display. We conducted a user study in order to evaluate the accuracy of this system compared to the accuracy of a capacitive touch monitor. The results show, that the system can't compete with an integrated system yet, but works well enough to be used as a touch detection system for large displays.
