A sensing module for sensing a rotation angle and a inclined angle of a users head is disclosed. The sensing module comprises a carrier, an acceleration parameter, an electric compass, and a transmitting interface. The carrier is configured to be mounted on the users head. The acceleration parameter, the electric compass and the transmitting interface are disposed on the carrier. The acceleration parameter is used to sense the inclined angle of the users head, and the electric compass is used to sense the rotation angle of the users head, and the transmitting interface is used to receive the rotation angle and the inclined angle and output the rotation angle and the inclined angle to a external system.本發明係揭露一種測量頭顱轉動角度和傾斜角度之偵測模組。此偵測模組至少包含:載具、加速度計、電子羅盤和傳送介面,其中載具係用以戴在使用者之頭顱上,而加速度計和電子羅盤則設置於載具上。加速度計係用以測量使用者頭顱之傾斜角度,電子羅盤係用以測量使用者頭顱之轉動角度,而傳送介面係用以接收傾斜角度和轉動角度,並將其輸出至外部系統。104‧‧‧加速度計106‧‧‧電子羅盤108‧‧‧傳送介面109‧‧‧顯示器200‧‧‧偵測模組202‧‧‧無線傳輸模組
