Throughout the animal kingdom the smell sense is often used to track the prey, or mark territory. Domesticated animals such as dogs are utilized for their ability to track specific compounds through an environment. In linguistics there is the term “I smell something fishy”. “Detective Smell” suggests using smell as way of investigating our environment and as a marker of authenticity or type of branding. In the future instead of using a sticker seal of integrity, a product may come with an original scent (i.e. genuine Luis Vuitton wallets/bags since there are many fakes). Scents are often clues, for example waking up to the smell of smoke indicates an ongoing fire. Perhaps aromas can be used to embed information in alerts and announcements.
