| Outline of Final Research Achievements |
A system that allows users to collaboratively collect and create learning materials through real-world sensing technologies using mobile devices. Achievements of the project are summarized as follows:
1. System development: A highly-precise time-synchronization technique between smartphones using illuminations and that for 3D localization of smartphones using acoustic signals are investigated. By using these techniques, a 3D reconstruction and motion-capture system by integrating multiple smartphone built-in cameras are implemented.
2. System evaluation and research outcomes presentation: The performance evaluations of the proposed system and user studies were conducted. Research outcomes were presented in academic meetings and published in a journal paper.

| Academic Significance and Societal Importance of the Research Achievements |
積極的な学習者(active learner)としての活動を強化するため、自身が学習素材を取得し、互いに協調しつつそれを編集することで、学習コンテンツを作成できる創造的学習支援環境の構築である。スマートフォン等の個人向け携帯端末で実現できる点で有用性は高いと言える。さらに、携帯端末間の高精度時刻同期技術、屋内での3次元位置認識技術、それらの技術に統合することによる3次元形状復元およびモーションキャプチャシステムは、技術的難易度が高く挑戦的な研究である。他分野への応用も考えられ学術的な意義も大きい。
