  • the intervention device may be a device that performs the intervention on a plurality of intervention sites of the living body, and the biometric system may subsequently perform the intervention for each of the intervention sites based on the biological information.
  • An intervention decision unit may be further provided to determine the content of the intervention.
  • the intervention content can be determined for each intervention site based on biological information.
  • the biometric measurement system of one aspect includes an intervention device that intervenes in a physical stimulus to the living body, a biological information measuring unit that measures the biological information of the living body, and the biometric information measuring unit that measures the biological information after the intervention is completed. It has a configuration including an intervention start determination unit that determines the start timing of the next intervention in the living body by the intervention device based on the biological information.
  • the start timing of the next intervention can be determined based on the biological information after the intervention is completed.
  • an intervention determination unit that determines the content of intervention of physical stimulation to the living body, a body composition calculation unit that calculates the body composition of the living body, and the body composition and the content of the intervention are included. It has a configuration including a storage unit that is associated and stored.
  • the biometric program of one aspect is determined by the intervention decision unit that determines the content of the intervention of physical stimulation to the living body, the biometric measurement section that measures the biological information of the living body, and the intervention decision section that measures the computer. It has a configuration that functions as an output unit that outputs the biological information measured by the biometric unit or information based on the biological information in association with the intervention.
  • a computer is used to measure an intervention control unit that causes an intervention device to intervene in a physical stimulus to a living body, and biometric information of the living body while the intervention device is performing the intervention. It has a configuration that functions as a biological measurement unit.
  • One aspect of the biometric program is an intervention control unit that causes an intervention device to intervene in a physical stimulus to a living body, a measurement control unit that causes a biometric device to measure biological information of the living body, and the intervention. Based on the biological information measured by the biological information measuring unit after the completion of the above, the intervention device has a configuration of functioning as an intervention start determining unit for determining the start timing of the next intervention in the living body.
  • One aspect of the biometric program is an intervention control unit that causes an intervention device to intervene in a physical stimulus to the living body, a measurement control unit that causes the biometric device to calculate the body composition of the living body, and a storage device.
  • it has a configuration that functions as a memory control unit that stores the body composition and the content of the intervention in association with each other.
