PROBLEM TO BE SOLVED: To propose a method of allowing a user to appropriately perform an action of predetermined schedule by effectively utilizing a body clock.SOLUTION: An information processing device is equipped with: a first information acquisition section which acquires priority action information in which a priority action of a user is associated with time at which the priority action is performed a second information acquisition section which acquires biological information regarding a body clock of the user at the present time a state setting section which sets an ideal state of the body clock corresponding to the priority action based on the acquired priority action information a state estimation section which estimates the present state of the body clock at the present time based on the acquired biological information a third information acquisition section which acquires set action information regarding a set action which is included in the schedule of the user and can be set at a given time and a display control section which allows a display section to display a state of the body clock in the schedule based on a target value used for changing a phase of the body clock at the present state to a phase of the ideal state and the acquired set action information.COPYRIGHT: (C)2014,JPO&INPIT【課題】体内時計を有効活用して、ユーザに所定のスケジュールの行動を適切に行わせる方法を提案する。【解決手段】ユーザの優先行動と、優先行動を行う時刻とを対応付けた優先行動情報を取得する第1情報取得部と、現在時刻のユーザの体内時計に関する生体情報を取得する第2情報取得部と、取得された優先行動情報に基づいて、優先行動に対応する体内時計の理想状態を設定する状態設定部と、取得された生体情報に基づいて、現在時刻における体内時計の現在状態を推定する状態推定部と、ユーザのスケジュールに含まれ、任意の時刻に設定可能な設定行動に関する設定行動情報を取得する第3情報取得部と、現在状態の体内時計の位相を理想状態の位相へ変位させるための目標値と、取得された設定行動情報とに基づき、スケジュールにおける体内時計の状態を表示部に表示させる表示制御部と、を備える、情報処理装置。【選択図】図1
