A wearable augmented reality system using positioning infrastructures and a pedometer

This paper describes a wearable augmented reality systemusing positioning infrastructures and a pedometer. Torealize augmented reality systems, the position and orientationof user's viewpoint should be obtained in real time. Theproposed system measures the orientation of user's viewpointby an inertial sensor and the user's position using positioninginfrastructures in environments and a pedometer.The system specifies the user's position using the positionID received from RFID tags or IrDA markers which are thecomponents of positioning infrastructures. When the usergoes away from them, the user's position is alternatively estimatedby using a pedometer. We have developed a navigationsystem using the proposed techniques and have proventhe feasibility of the system with experiments.
