Over the course of history, a number of mechanisms have been devised to measure the passage of time. Intricately positioned sundials, medieval clock towers, status imposing wristwatches—even the stars. Aisen Caro Chacin, though, experiments with a new method. The post-graduate fellow and Physical Computing lecturer at Parsons wants people to tell time using their nose. Her chemical-based watch, Scent Rhythm, emits a mist of six different smells that match up with the body’s internal clock. There’s coffee for the morning, the scent of money (it’s actually tarnish and paper) in the afternoon, a whiskey-and-tobacco musk in the early evening and soothing chamomile near midnight.
