Annotation Overlay with a Wearable Computer Using Augmented Reality

This paper describes an augmented reality system with a wearable computer to overlay an annotation relative to the real world. To realize an augmented reality system, a position of user’s viewpoint is needed for acquiring a relationship between the real and virtual coordinate systems. However, it is difficult that the user’s viewpoint is accurately measured in both inand out-door scene. In this paper, a wearable augmented reality system which can overlay an annotation on real scene is developed by using RFID tag and tag reader. The system can measure user’s position by RFID tag set up at appointed position where user thinks that it need an information relative to real scene; for example, a front of a guide plate and a blanch point. The feasibility of the system has been successfully demonstrated with experimental.
