This research aims to develop a mobile augmented reality positioning system for indoor construction application by tracking the coordinates of the user and their angles of vision so as to realize three-dimensional indoor positioning with high environmental adaptability. This research uses infrared invisible marker identification technique, and adopts the outside-in tracking mode to develop the Head Marker Tracking Augmented Reality (HMTAR) system, which can be mounted indoors or outdoors and has the extensive tracking capability, event memory mechanism, and scenario sharing mechanism. Evaluation results were obtained from Heuristic Evaluation and SUS evaluation. The results demonstrated a prospect for indoor augmented reality positioning technique.
