Information exchange method and information exchange system

摘要

An information exchange method includes steps of shaking a first electronic device and a 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 other.

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.
