方位情報を提供可能な新しい効率的なGPSの提案・設計と，それを用いた教育支援システムの検討

抄録

Regarding a pedestrian with Global Positioning System, it has been hard to steadily acquire his bearing just using GPS. In this paper, a novel practical method is proposed to acquire his azimuth instantaneously with a new wearable user segment of GPS even in his stillness. This is able to be used as an ideal input for the position and the orientation of the user. A novel educational system is also proposed using this device. This system assists a student who focuses on a certain azimuth range in his stillness, supposing his focus is on an object on his line of sight, by inquiring him whether he would like to have an educational story associated with it. Suitable objects for the system are also discussed and those are found to include celestial constellations, buildings of historical interest and relics, and perspectives of mountains in distance. This system enables us timely to provide suitable educational stories and practical guidance associated with the object interesting the student at the moment. The main factor of the superiority of the proposed system is revealed to be low uncertainty compared to traditional approaches. The proposed system, based on simple, economical and prevailing 1.5GHz band GPS receiver and several inventions by the author, is highly expected to be useful for education assistance in most areas of all over the world.
