Method, program, cumulative received-light amount estimation apparatus, and health care system using solar radiation amount information corresponding to position information of a device and time information
Abstract:
A method includes: receiving, by a terminal device, position information of the terminal device via a wireless signal, and time information; obtaining solar radiation amount information corresponding to the position information of the terminal device and the time information; obtaining a corrected received-light amount by correcting the amount of light received by the terminal device, based on a radio field reception intensity of the wireless signal that includes the position information, the amount of light received being indicated in the solar radiation amount information; and obtaining, by the terminal device, a cumulative value of amounts of light which the user of the terminal device has been exposed to, using the corrected received-light amount.
