PROBLEM TO BE SOLVED: To provide a device allowing a subject to effectively sense biological signal-based changes of an object.SOLUTION: A biological signal output device is provided that comprises: biological signal acquisition means 11 acquiring a biological signal including information on the strength of the biological signal from a subject operation control means 58 controlling operation of the object on the basis of the biological signal acquired by the biological signal acquisition means 11 and signal output means 61 outputting a signal showing operation of the object whose operation is controlled by the operation control means 58. The operation control means 58 is configured as means changing operation of the object in accordance with a relationship between the information on the strength of the biological signal and prescribed threshold.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】生体信号に基づくオブジェクトの変化を効果的に検体に感知させることができる装置を提供する【解決手段】検体から生体信号の強度情報を含む該生体信号を取得する生体信号取得手段11と、該生体信号取得手段11で取得された該生体信号に基づいて該オブジェクトの動作を制御する動作制御手段58と、該動作制御手段58で動作を制御された該オブジェクトの動作を表す信号を出力する信号出力手段61とを備える。該動作制御手段58は、該生体信号の強度情報と所定の閾値との関係に応じて該オブジェクトの動作を変化させる手段として構成される。【選択図】図1
