PROBLEM TO BE SOLVED: To perform pairing between specific electronic devices with a simple method.SOLUTION: A mobile phone and an electronic watch are each placed under a pairing waiting state (steps A2, B2). Then, intensity of light is changed with respect to a light-receiving sensor of the mobile phone and a solar panel of the electronic watch under the same light-receiving environment (steps A4, B4). Next, time-series data about a light reception amount, which is detected by the solar panel of the electronic watch when the light intensity is changed, is transmitted from the electronic watch to the mobile phone (step B5). Following this, an increase/decrease pattern of time-series data about a light reception amount, which is detected by the light-receiving sensor of the mobile phone when the light intensity is changed, and an increase/decrease pattern of the light reception amount time-series data transmitted from the electronic watch are analyzed (step A5). Finally, when it is determined that the increase/decrease patterns match each other (step A6; YES), pairing is performed between the mobile phone and the electronic watch (steps A7, B6). |
