A drowsiness prevention device includes a psychological state estimator and a controller. The psychological state estimator estimates a psychological state of an occupant, based on a state of the occupant detected by a detection device. The controller causes an output device to output a first warning and a second warning which are for alerting the occupant. The psychological state estimator estimates a first psychological state of the occupant which is before the first warning is output and a second psychological state of the occupant which is after the first warning is output. The controller determines details of a second warning, based on only the second psychological state or based on both the first psychological state and the second psychological state.

A visual field calculation apparatus capable of accurately calculating a visual field range of a user without using a complex configuration is provided. The visual field calculation apparatus includes a saccade detector that detects a saccade on the basis of a first gaze direction detected at a first timing and a second gaze direction detected at a second timing, a saccade speed calculator that calculates speed of the saccade on the basis of a time difference between the first timing and the second timing, the first gaze direction, and the second gaze direction, and a visual field range calculator that calculates a displacement vector of a saccade whose speed exceeds a first threshold, and calculates an area including a final point of the displacement vector as the visual field range of the user.

In a display control device, in accordance with speed limit information input from an input unit, a control unit senses change in a speed limit of a road where a vehicle travels and after that, in accordance with vehicle information input from the input unit, determines whether or not whether necessity to increase conspicuity of notification of the change in the speed limit. When it is determined that the necessity is high, a display unit is caused to switch display on a display medium from a first presentation image to a second presentation image that indicates a second speed limit by a first switching method. When it is determined that the necessity is not high, the display of the first presentation image is switched to the display of the second presentation image by a second switching method different from the first switching method.
