To provide an information processing device capable of specifying a bed-leaving state and variation information of a subject on the basis of variation information such as biological information.SOLUTION: The device comprises: storage means capable of storing first information for specifying a bed-leaving state of a subject such as a biological signal and second information for specifying an environmental state around the subject such as a temperature； transmitting means capable of transmitting the first information and the second information to the outside； receiving means capable of receiving predetermined setting data from the outside； and generating means capable of generating the specific information on the basis of the setting data. The transmitting means can transmit the specific information to the outside together with the first information and the second information.SELECTED DRAWING: Figure 1【課題】生体情報などの変動情報に基づき被験者の離床状態や変動情報を特定可能な情報処理装置を提供する。【解決手段】生体信号など被験者の離床状態を特定するための第１情報と、温度など被験者の周囲の環境状態を特定するための第２情報とを記憶可能な記憶手段と、第１情報及び第２情報を外部に送信可能な送信手段と、外部から所定の設定データを受信可能な受信手段と、設定データに基づいて特定情報を生成可能な生成手段とを備え、送信手段は、第１情報及び第２情報とともに、特定情報を外部に送信可能な構成にしてある。【選択図】図１
