INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND SYSTEM

To provide an apparatus that processes information regarding motion sickness of an occupant in a movable object. The information processing apparatus includes: a motion sickness accumulation computing unit that calculates an accumulation factor of motion sickness of an occupant in a movable object; a motion sickness recovery computing unit that calculates a recovery factor of the motion sickness of the occupant; and a motion sickness computing unit that combines the accumulation factor and the recovery factor to calculate a motion sickness index of the occupant. The motion sickness accumulation computing unit computes the accumulation factor by using a head motion of the occupant which is predicted by head motion simulation computing based on acceleration of the movable object and body information of the occupant.
