Today the systems 4DX and MX4D are used to provide scents in movie theatres. The MX4D system diffuses scents chosen according to the film being shown from cartridges incorporated in the armrests of the seats, while the scents generated with 4XD come from the backrest of each seat and are diffused backwards. The Disneyland and Walt Disney World theme parks also use these olfactory cinema techniques in their specialized cinemas.
