An attention interacting system is provided. The attention interacting system includes a brain wave detecting device and an audio playback device. The brain wave detecting device includes a body, a brain wave receiving unit and a control module. The brain wave receiving unit is disposed at the body and receives a brain wave signal of a user. The control module is coupled with the brain wave receiving unit and deals with the brain wave signal of the user to generate an attention relative signal. The control module generates a control signal according to the attention relative signal. The audio playback device is coupled with the control module. The audio playback device receives the control signal and adjusts the broadcasted state of a first audio according to the control signal.本發明係提供一種專注力互動系統,包括一腦波偵測裝置以及一音訊播放裝置,腦波偵測裝置包括一本體、一腦波接收單元以及一控制模組,腦波接收單元設置於本體並接收一使用者的腦波資訊,控制模組與腦波接收單元耦接,控制模組接收使用者的腦波資訊並對其進行處理,以產生一專注力相關訊號,並依據專注力相關訊號產生一控制訊號,音訊播放裝置與控制模組耦接,音訊播放裝置接收並依據控制訊號調整一第一音訊的播放狀態。1‧‧‧專注力互動系統11‧‧‧腦波偵測裝置111‧‧‧本體112‧‧‧腦波接收單元113‧‧‧控制模組12‧‧‧音訊播放裝置
