There are other noncommercial ideas for digital scents. Bell has been developing a ”chemical camera“ that could sniff out harmful chemicals or the presence of disease in a patient.
And then there‘s the creation of multisensory immersive environments for their own sake. Smith calls the art of using smell ”scentography,“ and expects aroma to be used even as a scent track to add emotional resonance to films.
But first we’ll have to be taught to distinguish odors as elements of a work of art, the way we learned to distinguish ”sound art“ from music. Industrial noise once sounded like nothing, literally nothing. Over time, we learned to listen to ambient noise as elements of sound sculpture, changing what had been perceived as merely context into primary content. Scent may one day speak to us that clearly.
