An information generation unit (20: S10~S40) generates a time series of detection elements using, as the detection elements, a state indicating which of a plurality of preset viewing regions the line of sight of a driver driving a vehicle is directed, and an opened/closed state of the eyes of the driver. An extraction unit (S50) uses a time window having a preset time width and extracts detection data from the time series of detection elements. A tabulation unit (S60) uses the detection data and tabulates the state of the line of sight of the driver for each viewing region. A determination unit (S70) determines, from the tabulation results obtained by the tabulation unit, the consciousness state of the driver with regard to the plurality of viewing regions or an event associated with each of the plurality of viewing regions.
