Paper Abstract

This paper describes an optical tracking method developed using Wii Remotes. The motion and rotation of an object with markers and an accelerometer is tracked using the optical sensors in two Remotes. Initialization is complicated by the nature of the Wii Remote's sensor: while it can track up to four points, there is no trivial means to uniquely identify an individual marker. To resolve this ambiguity, a brute force approach is used. All possible correspondences are considered, using the Remotes' and tracked object's accelerometers as inclination sensors to identify potentially correct ones. The resulting method is applied to create a largely self-calibrating six-degree-of-freedom input device. We also provide documentation sufficient for others to use the Wii Remote in research.
