To provide an electronic apparatus capable of performing an adaptive physical condition estimation in consideration of a period in which a physical condition easily becomes abnormal after a work is resumed.SOLUTION: The electronic apparatus includes a biological information acquisition unit 101, a physical condition estimation unit 102, and an action change detection unit 103. The biological information acquisition unit 101 acquires biological information including a body movement amount. The physical condition estimation unit 102 estimates the physical condition of a living body on the basis of the biological information. The action change detection unit 103 detects a change in the action of the living body on the basis of the biological information. The action change detection unit 103 corrects a reference value of the physical condition estimation or changes a physical condition estimation method on the basis of a change in the action of the living body.SELECTED DRAWING: Figure 4【課題】作業再開後の体調に変調を来し易い期間を考慮した適応的な体調推定を行うことができる電子機器を提供する。【解決手段】電子機器は、生体情報取得部101と、体調推定部102と、行動変化検知部103とを具備する。生体情報取得部101は、体動量を含む生体情報を取得する。体調推定部102は、前記生体情報に基づき、生体の体調を推定する。行動変化検知部103は、前記生体情報に基づき、前記生体の行動の変化を検知する。前記行動変化検知部103は、前記生体の行動の変化に基づき、体調推定の基準値を補正または体調推定方法を変更する。【選択図】図4
