| Outline of Final Research Achievements |
In this study, we developed a choker device that non-invasively realizes biological information sensing from the neck and can also present information through the various senses of the neck.
The audio signals were acquired by a microphone attached to the pharynx. The bone transfer function was estimated based on the measurement of air conduction sound and bone conduction sound, then was applied to audio signal processing. We made quantitative estimation of swallowing amount from audio signal by machine learning. For measurement of cardiovascular system, we measured by photoplethysmogram and capacitive coupling. For information presentation, we have realized haptic devices based on vibrotactile presentation, force-tactile simultaneous presentation with air jet, force presentation by generating resistance using MR (Magnetorheological) fluid, and thermal sensation presentation.

| Academic Significance and Societal Importance of the Research Achievements |
超高齢社会における社会システムの持続性のためには，健康長寿の確立が重要であり，未病を改善し病気の予防につなげていくことが必要である．日常的に装着可能な生体センシングシステムにより，定期的な検診では検出できない生体の異常を把握することが可能になる．本研究では従来は定量が困難であった飲食物の量的把握手法を構築した．またセンシングのみならず五感を通じた情報の提示により，自身の生体情報を言葉によらず継続的に知ることができ，生活習慣の改善に役立てられると考えられる．
