To integrally process data from a sensor to determine a variety of pieces of risk.SOLUTION: A system according to an embodiment defines an index associated with heat-stroke risk of a user as a first risk value when sensor measurement air pressure has a first value, and defines the index associated with the heat-stroke risk of the user as a second risk value larger than the first risk value when the sensor measurement air pressure has a second value smaller than the first value. And, when the sensor measurement air pressure has the first value, the system defines an index associated with stress risk or depression risk of the user as the first risk value, and when the sensor measurement air pressure has a second value smaller than the first value, the system defines the index associated with the stress risk or the depression risk of the user as the second risk value larger than the first risk value. And, when the sensor measurement air pressure has the first value, the system defines an index associated with coldness risk or frostbite risk of the user as the first risk value, and when the sensor measurement air pressure has the second value smaller than the first value, the system defines an index associated with the coldness risk or the frostbite risk of the user as the second risk value larger than the first risk value.SELECTED DRAWING: Figure 1【課題】 センサからのデータを統合的に処理して種々のリスクを判定する。【解決手段】 実施形態のシステムは、センサ測定気圧が第１値の場合、ユーザの熱中症のリスクに関する指標を第１リスク値と定め、センサ測定気圧が第１値より小さい第２値の場合、ユーザの熱中症のリスクに関する指標を前記第１リスク値より大きい第２リスク値と定める。また、センサ測定気圧が第１値の場合、ユーザのストレス又はうつ病のリスクに関する指標を第１リスク値と定め、センサ測定気圧が第１値より小さい第２値の場合、ユーザのストレス又はうつ病のリスクに関する指標を第１リスク値より大きい第２リスク値と定める。また、センサ測定気圧が第１値の場合、ユーザの寒さ又は凍傷のリスクに関する指標を第１リスク値と定め、センサ測定気圧が第１値より小さい第２値の場合、ユーザの寒さに又は凍傷のリスクに関する指標を第１リスク値より大きい第２リスク値と定める。【選択図】図１
