A dual-Wiimote 3D localization scheme has been developed for improving the spatial resolution and extending the sensing space of the original demonstrated single Wiimote 3D scheme. This scheme utilizes two pairs of Wiimotes to form a dual stereo vision and a kinematics relation is established to extract the 3D position of objects by using geometric transformation. The experimental results indicate that this scheme is effective in achieving the above mentioned goals. A demonstration by incorporating an omni-wheel robot and a quadcopter under a Wiimote sensing environment has been performed to examine the feasibility of the localization method. The demonstration indicates that with properly integration with this scheme, it is expected applications such as positioning of indoor mobile robots and human motion capture for animations could achieve a better performance.
