Device for controlling motion sickness, which is integrated into a motor vehicle

A method for displaying light markers intended to combat motion sickness, the method including the following steps:

• detecting accelerations of a motor vehicle along 3 axes,
• detecting a physical parameter of a person seated in the motor vehicle, and
• driving a display means for displaying light markers capable of forming at least one first artificial horizon line at a level of a first internal surface of the motor vehicle and at least one second artificial horizon line at a level of a second internal surface of the motor vehicle, said at least one first artificial horizon line and said at least one second artificial horizon line each defining a horizontal plane and being formed in a field of view of a first person seated in the motor vehicle, the horizontal plane being perpendicular to a gravitation vector, wherein a position along the gravitation vector of an intersection of said horizontal plane with the gravitation vector being aligned with the detected physical parameter of the person and aligned with a position of eyes of the first person seated in the motor vehicle;
• wherein the display means comprises at least three light columns oriented vertically, the at least three light columns including a first light column arranged in alignment with the first internal surface and in alignment with the second internal surface, a second light column arranged in alignment with the second internal surface and to the left or to the right of the first light column, and a third light column arranged in alignment with the first internal surface and closer to the rear of the vehicle than the first light column, each light column of the at least three light columns being formed of a plurality of vertically aligned light points, each light point of the plurality of vertically aligned light points being able to emit light in an activated state and not emit light in a deactivated state, and the at least one first artificial horizon line is formed by a first virtual line passing through one of a highest activated light point of the first and third light column and a lowest activated light points on the first and third light column and the at least one second artificial horizon line is formed by a second virtual line passing through one of the highest activated light point of the first and second light column and the lowest activated light point on the first and second light columns respectively;
• selecting a height of the one of the highest light point of each of the at least three light columns and the lowest light point of each of the at least three light columns such that the height of the one of the highest light point and the lowest light point aligns with the detected physical parameter of the person, wherein the detected physical parameter is a detected height of the eyes of the first person;
• and
• mechanically displacing each of the at least three light columns such that the one of the highest activated light point and the lowest activated light point is at a physical height of the detected physical parameter of the first person.
