The control unit calculates a difference between the atmospheric pressure value included in the atmospheric pressure information acquired by the atmospheric pressure information acquisition unit and the atmospheric pressure value included in the atmospheric pressure information transmitted from the roadside device, and the calculated difference The electronic device according to claim 4, wherein the user's approach to the pedestrian bridge is detected on the condition that the converted height difference matches the height information with a predetermined accuracy. A control method for causing an electronic device to include an acceleration information acquisition unit that acquires acceleration information and a rotation information acquisition unit that acquires rotation information,
Based on the acceleration information, determining whether the user of the own device is riding on a bicycle and moving;
Determining that the user is on a bicycle, determining whether the user is moving on a pedestrian bridge based on the rotation information. In an electronic device comprising an acceleration information acquisition unit for acquiring acceleration information and a rotation information acquisition unit for acquiring rotation information,
Based on the acceleration information, determining whether the user of the own device is riding on a bicycle and moving;
A control program that, when it is determined that the user is riding a bicycle, determines whether the user is moving on a pedestrian bridge based on the rotation information.
