Abstract
A device, method and computer program product provide driver state estimation. A first index value correlated with an amount of an attention source allocated to top-down attention of a driver and a second index value correlated with an amount of the attention source allocated to bottom-up attention of the driver are determined. The driver state including an attention function degraded state of the driver is estimated based on the first index value and the second index value. A vehicle being operated by the driver may be controlled in accordance with the estimated driver state.
