Abstract
An interactive method for communication with a smart mobile device and an interactive communication system using the same are provided. The interactive communication system comprises an external device and a smart mobile device. The external device comprises a microprocessor circuit and an AC magnetic emitter. The microprocessor circuit is for encoding specific data into an encoded signal. The AC magnetic emitter is for converting the encoded signal into an AC magnetic signal. The smart mobile device comprises an E-compass sensor. In addition, the smart mobile device stores a specific application program for acquiring a magnetic variation of the E-compass sensor. When the magnetic variation of the E-compass sensor is greater than a threshold variation, the AC magnetic signal is decoded through the specific application program to obtain the specific data.
