  • Publication number: 20220081009
    Abstract: A configuration that decides whether or not a driver has alertness sufficient for manual driving by analyzing eye behaviors of the driver trying to solve a problem displayed on the display section is realized. It is made possible to decide whether or not the driver of a moving apparatus that can be driven in a driving mode that can be switched to automated driving and manual driving has alertness sufficient to return to manual driving on the basis of eye behaviors of the driver. An eye-behavior analyzing section that analyzes an eye behavior of the driver who observes a problem displayed on a display section and an alertness deciding section that decides alertness of the driver on the basis of a result of the analysis by the eye-behavior analyzing section are included. The alertness deciding section analyzes whether or not the driver executes an eye behavior such as a fixation or a microsaccade for solving the problem, and decides whether or not the driver has alertness sufficient to return to manual driving.

  • Publication number: 20210016805
    Abstract: A configuration is realized in which driver's biological information is input and a driver's wakefulness degree is evaluated. The wakefulness degree of the driver is evaluated by applying a result of behavior analysis of at least one of an eyeball or a pupil of the driver and a wakefulness state evaluation dictionary specific for the driver. The data processing unit evaluates the wakefulness degree of the driver by using the wakefulness state evaluation dictionary specific for the driver generated as a result of learning processing based on log data of the driver's biological information. Moreover, a return time before the driver is able to start safety manual driving is estimated. A learning device used for estimation processing based on observable information is able to correlate an observable eyeball behavior of the driver and the wakefulness degree by a multidimensional factor by continuously using the learning device.
