Outline of Final Research Achievements

In this study, we examined a framework for integrating activity recognition and indoor positioning, and in particular, we aimed to make use of deep learning.
In PDR (Pedestrian Dead-Reckoning), we constructed an end-to-end deep learning PDR that directory acquires a relative position change from sensor data. We also propose indoor context estimation using environmentally installed devices. We use noise reduction based on deep learning for BLE (Bluetooth Low Energy) radio strength. Our data obtained through the research activities were made available to the world via http://hub.hasc.jp. In addition, we have developed a system named Synerex for supply and demand exchange as a fundamental platform for data collection.

Academic Significance and Societal Importance of the Research Achievements

屋内コンテキスト推定技術は,ユーザの行動意図を理解し,支援することが究極の目的と言える.本研究はその基盤技術の獲得を目指しており,「屋内コンテキスト推定」という新しい普遍的な研究分野の確立が期待でき,その社会適用範囲も非常に広い.また代表者はこれまですでに国際ワークショップ(HASCA2013-2020),国際コンペティション(PDR Challenge)を実現しており,本研究により日本の「コンテキスト・アウェア」研究技術を世界に広めることができた。さらに、End-to-endの深層学習による成果や、開発された基盤システム Synerex は多様な活用可能性が期待できる。
