Several types of hand-held devices have been developed in order to enable interactive manipulations in mixed reality space. Position and posture estimations of the device are required for direct manipulation with virtual objects. Fiduciary markers or large-scale motion capture systems are usually used for these estimations because they can be identified easily. However, they encounter problems with estimation stability, and the device shows decreased portability due to system scale, determining area, and disturbances. To avoid these problems, we propose a hybrid method for tracking hand-held devices that combines vision-based registration with pose information obtained from a physical 3DOF orientation sensor. In vision-based methods, estimations are performed with device forms and LED active markers. We confirmed that the new device tracking method can provide tracking stability.
