Abstract

When continuous user biometric information is transmitted to a server device continuously from a handheld device used by a user, the server device can be caused to receive a required measurement value efficiently at a required time, select information desired by the user on the basis of the measurement value and user peripheral information, and provide the user with the information reliably, without imposing excessive communication charges and the like. A server device 140 is used together with a handheld device 110 that transmits the user peripheral information to the server device and receives the information transmitted from the server device. After determining that a fluctuation has occurred in the user peripheral information transmitted from the handheld device 110, the server device 140 performs either processing for calculating a predicted value of future user biometric information or processing for receiving the predicted value of the future user biometric information, selects information on the basis of the predicted value and the user peripheral information, and transmits the selected information to the handheld device 110.
