The present invention relates to a physiological feedback system used for providing breath guide signal and physiological activity information as the bases for a user to self adjust physiological activity in a training section, so as to achieve a feedback loop. The system comprises a wearable physiological sensing device having at least one physiological sensing element arranged on the user to obtain physiological signals associated to users physiological activity, and an independent light emitter for generating a visually perceptible signal comprising an illumination intensity variation and an illumination color change, wherein the illumination behavior represents the breath guide signal via illumination intensity variation and represents the information associated to users physiological activity via the illumination color change, so that the user can perform a breath behavior model according to the illumination intensity variation and a self-awareness control according to the illumination color change to influence the physiological condition.本發明關於一種生理回饋系統,用以提供呼吸導引訊號以及生理活動資訊,以作為使用者在一訓練區段中自我調整生理活動的基礎,進而達成一回饋迴路,該系統包括一穿戴式生理感測裝置,具有至少一生理感測元件,設置於該使用者身上,以取得相關使用者生理活動的生理訊號,以及一獨立發光體,用以產生包括一發光強度變化以及一發光顏色變化的一視覺可感知訊號,其中,該發光行為透過該發光強度變化表現該呼吸導引訊號,以及透過該發光顏色變化表現該相關使用者生理活動的資訊,以讓使用者可根據該發光強度變化而進行一呼吸行為模式,以及根據該發光顏色變化而進行一自我意識調控,以對達成對生理狀態的影響。10‧‧‧頭戴式腦電檢測裝置12‧‧‧發光體
