Vision and perspective and the future of DOS
Olfaction is generally considered as a minor sense, although in the food and beverage industry as well as in perfumery is undoubtedly the first one. Digital olfaction could also be considered as the third digital sense in terms of users and performance, after computer vision and digital audio. Unlike these senses, olfaction suffers from the phenomenon of olfactory fatigue (or olfactory adaptation), it’s also important to realise that aroma chemistry is complex, and the smell of any scent is never really the consequence of a single chemical compound. All this makes the development of a digital olfactory system not an easy task.
