Driver monitoring device, driver monitoring method, and storage medium

A driver monitoring method executed by a computer, the driver monitoring method comprising:

• a biometric information recognition step of recognizing biometric information of a driver of a moving body;
• a driving behavior recognition step of recognizing driving behavior of the driver, who is driving the moving body;
• a driving risk recognition step of recognizing, using a predetermined recognition method, a driving risk indicating a risk level of movement of the moving body due to driving of the driver, based on at least one of the biometric information of the driver recognized in the biometric information recognition step and the driving behavior of the driver recognized in the driving behavior recognition step, when the driver is driving the moving body;
• and
• a driving risk recognition method switching step of switching the recognition method used when the driving risk is recognized at a next recognition timing in the driving risk recognition step, according to the driving risk recognized in the driving risk recognition step.

A non-transitory computer-readable storage medium storing a program causing a computer to function as:

• a biometric information recognition portion that recognizes biometric information of a driver of a moving body;
• a driving behavior recognition portion that recognizes driving behavior of the driver, who is driving the moving body;
• a driving risk recognition portion that recognizes, using a predetermined recognition method, a driving risk indicating a risk level of movement of the moving body due to driving of the driver, based on at least one of the biometric information of the driver recognized by the biometric information recognition portion and the driving behavior of the driver recognized by the driving behavior recognition portion, when the driver is driving the moving body;
• and
• a driving risk recognition method switching portion that switches the recognition method used when the driving risk recognition portion recognizes the driving risk at a next recognition timing, according to the driving risk recognized by the driving risk recognition portion.
