Disney has patented a ‘Smell-O-Vision’ immersive scent system, designed to augment the emotional responses of guests using attractions at theme parks.

The innovative system combines a number of scent distributors to accompany visual entertainment with nasal stimulation.

Saying smell is “arguably the most powerful human sense,” Disney hopes that the Smell-O-Vision technology will trigger memories and create powerful emotional responses.

One key feature of the patent is that the amount of scent released can be varied and can be omitted simultaneously with visual objects.

Smell-O-Vision technology was developed as early as the 1960s, when it was used in the film ‘Scent of Mystery,’ when 30 different odours were incorporated into the screening.

However, smell-focused technology has yet to be successfully deployed in the amusement park industry, something which Disney plans to master.
