 note = {疲労やストレスなどの指標となる咬合力の推定は，医療分野やエンタテインメント分野での利用の関心が持たれている．一方で，咬合力を計測する場合は，口腔内に機材を入れたり，顔表面に貼り付けて利用するものが多く，日常的な環境下で長時間使用することには適していない．そこで本研究では，人間が顎に力を入れた際に咬筋の収縮に応じて，顔皮膚表面の変形が起こる現象に着目する．この変形を，反射型光センサで直接的な皮膚表面への接触なく咬筋の膨張収縮を計測し，咬合力を推定するシステムを開発する．, The estimation of bite force, which can be an index of food texture or one's stress level, may be used in the medical field or for entertainment purposes. Current methods for estimating bite force often requires putting instruments into the mouth or attaching it on the face, which would not be suitable for long-term use. We focused on the deformation of facial skin which changes according to the expansion of the jaw muscles during jaw clenching. By using photo reflective sensors for measuring the expansion and contraction of jaw muscles, we developed a system which can estimate the bite force without any contact to the skin.},
