1. An information exchange method comprising:

  • a user stacking a first electronic device and a second electronic device with each other and shaking the first electronic device and the second electronic device simultaneously;

    recording a first vibration waveform of the first electronic device and recording a second vibration waveform of the second electronic device;

    determining whether the first vibration waveform and the second vibration waveform match each other; and

    transmitting a first information related to the first electronic device to the second electronic device when the first vibration waveform and the second vibration waveform match each others;

    wherein determining whether the first vibration waveform and the second vibration waveform match each other comprises;

    detecting N first characteristic points of the first vibration waveform and detecting N second characteristic points of the second vibration waveform, wherein N is a positive integer larger than one;

    calculating a first time interval between every two adjacent first characteristic points so as to obtain N−

    1 first time intervals and calculating a second time interval between every two adjacent second characteristic points so as to obtain N−

    1 second time intervals;

    calculating a time difference between each of the first time intervals and each of the second time intervals so as to obtain N−

    1 time differences; and

    determining that the first vibration waveform and the second vibration waveform match each other when each of the N−

    1 time differences is smaller than a first threshold.
