Abstract

This paper describes a real-time 3-dimensional head tracking for an indoor wearable navigation system using augmented reality, which provides navigation information as virtual objects overlaid on the real scene. We propose a hybrid tracking with a pair of stereo-camera and an orientation sensor, which localizes a 3-dimensional position and orientation of a user's head. Discretely located infrared markers in the workspace are used as fiducial markers. Through some experiments, it is shown that this tracking system has reasonable accuracy enough to provide navigation information.
