1. An automatic navigation method, comprising:
- providing a guiding path;
obtaining a current facing direction which a user faces by an electronic compass;
obtaining a turning direction according to the current facing direction and the guiding path;
notifying the turning direction by an electric shock signal;
obtaining a nearest trace point of the guiding path by sensing a radio-frequency identification (RFID) tag; and
updating the turning direction according to the nearest trace point and the current facing direction;
wherein the electric shock signal is directed towards left turn or right turn by providing a combination of at least one short-duration signal and at least one long-duration signal.

Abstract
An automatic navigation method and automatic navigation system are provided. The automatic navigation method includes the following steps. A guiding path is provided. A current facing direction which a user faces is obtained by an electronic compass. A turning direction is obtained according to the current facing direction and the guiding path. The turning direction is notified by an electric shock signal. A nearest trace point of the guiding path is obtained by sensing a radio-frequency identification (RFID) tag. The turning direction is updated according to the nearest trace point and the current facing direction.
