Abstract: A motion estimation system includes a head motion detection unit, a mobile body motion detection unit, and a movement estimation unit. The head motion detection unit is worn on an occupant in a mobile body, and detects a motion of a head of the occupant. The mobile body motion detection unit detects a motion of the mobile body. The movement estimation unit obtains the motion of the head of the occupant and the motion of the mobile body, and estimates a movement of the head of the occupant made by the occupant according to a difference between the motion of the head of the occupant and the motion of the mobile body.
