Detecting 3D position and orientation of a Wii remote using webcams

Abstract

In this paper we present a method to detect the three dimensional position and orientation of a Wii Remote with one or more emissive spheres attached to it, providing an input device that has six degrees of freedom. Unlike other systems, our system can focus in different directions surrounding the user, with a high precision, and at a low cost. We describe the way object-, motion- and orientation tracking is done, as well as the applicability of the final product. We further describe how to improve the noisy data that is retrieved from the sensors of the Wii Remote, how to smooth detected positions, and how to extrapolate position and orientation. © 2011 Springer-Verlag.
