Abstract
An arousal level determination device, which determines an arousal level of a driver driving a vehicle, includes a detection part and a determination part. The detection part is configured to detect an amount of body movement indicating a magnitude of movement of a body of the driver. The determination part is configured to determine the arousal level of the driver. The determination part determines that the driver is in an initial stage of decline in the arousal level when the amount of body movement has a decreasing trend.
Claims10
An arousal level determination device that determines an arousal level of a driver driving a vehicle, the arousal level determination device comprising:
- a detection part configured to detect an amount of body movement indicating a magnitude of movement of a body of the driver;
- and
- a determination part configured to determine the arousal level of the driver, wherein
- the determination part determines that the driver is in an initial stage of decline in the arousal level when the amount of body movement has a decreasing trend, and
- the determination part determines that the driver is in a progressive decline stage in the arousal level when the amount of body movement is changed from a decreasing trend to an increasing trend.
A computer-implemented method for determining an arousal level of a driver driving a vehicle, the computer-implemented method comprising:
- detecting an amount of body movement indicating a magnitude of movement of a body of the driver;
- and
- determining the arousal level of the driver, in which the driver is determined to be in an initial stage of decline in the arousal level based on the amount of body movement having a decreasing trend, and the driver is determined to be in a progressive decline stage in the arousal level based on the amount of body movement changing from a decreasing trend to an increasing trend.
