A wakefulness maintenance apparatus includes a presentation recording unit and a presentation execution unit. The presentation recording unit records in-vehicle presentation contents each including a corresponding one of scenes, an auditory stimulus action associated with the scene, and at least one stimulus action selected from a group of a visual stimulus action, a tactile stimulus action, and an olfactory stimulus action which are associated with the scene. The presentation execution unit executes, based on the in-vehicle presentation contents recorded in the presentation recording unit, an in-vehicle presentation including provision of: the auditory stimulus action associated with the scene, and the at least one stimulus action selected from the group of the visual stimulus action, tactile stimulus action, and olfactory stimulus action which are associated with the scene.

A feeling monitoring system includes a facial image acquisition portion, a feeling information acquisition section, and a feeling display generation section. The facial image acquisition portion is capable of acquiring a facial image of an occupant individually sitting in each seating position of two or more seating positions in a vehicle. The feeling information acquisition section acquires feeling information representing the feeling of the occupant based on the facial image acquired from the facial image acquisition portion. The feeling display generation section generates a feeling display corresponding to the feeling information acquired by the feeling information acquisition section.

A drowsiness detector detects the drowsiness by measuring a distance of an eyebrow at three points from a reference line defined by an inner eye corner and an outer eye corner. The three distances of the eyebrow from the reference line are respectively standardized by an inter-eye distance between the inner eye corners of the left and right eyes, and are respectively compared with thresholds for determining the rise of the eyebrow. The rise of the eyebrow is then translated as the start of the drowsiness, and is associated with an operation such as a doze prevention operation or the like.
