A Quantitative Comparison of Position Trackers for the Development of a Touch-less Musical Interface

This paper presents a comparison of three-dimensional (3D) position tracking systems in terms of some of their performance parameters such as static accuracy and precision, update rate, and shape of the space they sense. The underlying concepts and characteristics of position tracking tech-nologies are reviewed, and four position tracking systems (Vicon, Polhemus, Kinect, and Gametrak), based on dif-ferent technologies, are empirically compared according to their performance parameters and technical specifications. Our results show that, overall, the Vicon was the position tracker with the best performance.
