Augmented Reality(AR) is a promising technology which is able to augment the information of the real environment with virtually displayed informations. Wearable Computer(WC) is another promising technology which augments a personal information environment. The fusion of AR and WC is an ideal solution of personally augmentation of the real environment. However, because a HMD has limited field of view, the above systems are not able to augment the real environment outside of field of view. Therefore, an efficient and friendly visual information displaying which navigates the user's view to outside of HMD is necessary for practical wearable AR systems. This paper discusses what type of visual navigating the most suitable for wearable AR systems is. For the evaluation of the navigation, a prototype system which supports astronomical observation is constructed. A gyro sensor and an image sensor are utilized for the detection in user's view direction, and the registration between the user's view and the star map is realized by a realtime image processing in video see-through paradigm. The system installs several types of visual guidance to find a particular star. Evaluations with the prototype result their efficiencies and subjective impressions.
