PROBLEM TO BE SOLVED: To estimate condition of mind and body more precisely.SOLUTION: A biological information estimating apparatus is provided which comprises a biological sensor 10 for continuously acquiring biological information from a user, a mind and body condition estimating section 23 for carrying out an operation for acquiring a mind and body condition estimated value showing the degree of mind and body condition of a user on the basis of the biological information from the biological sensor, a user input section 24 for acquiring, as a user input value, degree of actual mind and body condition of a user with respect to the mind and body condition estimated value, and a section 26 for calculating coefficient for mind and body condition estimation which corrects a parameter used in the operation on the basis of the mind and body condition estimated value acquired by the mind and body condition estimating section 23 and the user input value acquired by the user input section 24.COPYRIGHT: (C)2008,JPO&INPIT【課題】より高い精度で心身状態の推定を行うことを可能にする。【解決手段】ユーザから継続的に生体情報を得る生体センサ10から送られてきた上記生体情報に基づいて、ユーザの心身の状態の度合いである心身状態推定値を求める演算を行う心身状態推定部23と、当該心身状態推定値に対するユーザの実際の心身の状態の度合いをユーザ入力値として取得するユーザ入力部24と、心身状態推定部23で求めた心身状態推定値とユーザ入力部24で取得したユーザ入力値とに基づいて、上記演算に用いるパラメータの補正を行う心身状態推定用係数算出部26とを備える。【選択図】図1
