A method includes: receiving, from at least one physiological information detecting sensor, flag information indicating whether an acceleration of the physiological information detecting sensor is higher than a threshold or not, and sensor identification information of the physiological information detecting sensor, wherein the flag information and the sensor identification information are associated with each other, and the physiological information detecting sensor stores first software; displaying the sensor identification information on a display; changing a visual aspect of the sensor identification information displayed on the display in accordance with the flag information; transmitting second software for updating a version of the first software to the physiological information detecting sensor indicated by the sensor identification information selected through a user input operation; and updating the version of the first software based on the second software.
