Improved accuracy tracking using synchronized Wiimote cameras

A new method and a prototype system for optical tracking using camera sensors from Nintendo Wii remote controllers are introduced. The system is of very low cost and can easily be extended to cover large areas. By bypassing the native Bluetooth interface and increasing the image analysis rate, extraordinary real-time performance is achieved. To overcome computational difficulties and uncertainties relating to the asynchronous nature of Wiimote cameras, a method is introduced to synchronize the measurements of each camera in the system. This unconventional synchronization scheme is widely applicable to numerous already existing Wiimote tracking systems improving their performance. The demonstrated tracking system is targeted for virtual and augmented reality applications as well as general purpose localization. An extensive analysis of the system performance and new findings of the camera characteristics are reported.
