Scent Rhythm

Interface: Scent Rhythm. 05/13
Scent Rhythm is timekeeping device that maps relational olfactory sequences to the body's circadian cycle. The sense of smell is a chemoreceptor, which means that these sensors can detect chemicals. The sense of time, chronoception, is not based on the function of a specific organ, but rather the result of the interaction of the cerebral cortex, cerebellum and basal ganglia. This device attempts to keep a chemical watch on the circadian rhythm, by administering fragrance+supplement concoctions associated with the daily activity of the moment to promote the production of certain neurotransmitters, such as chamomile+melatonin during sleep, espresso+caffeine during the awaken state.

In this video you can see the user interaction to set a new scent cycle. If you look carefully the user is clicking the button and cycling through the top-left most atomizer, and clockwise to the second. 1 click is sleep, 2 is awaken, 3 is active, and 4 is rest. One 3 sec. click will reset the watch to the normal function mapped to ET time zone.
