We made it our mission to better understand the human senses. What is been realized was that the sense of smell is most closely linked to memory and emotions. The strategy was to demonstrate the feelings and emotions of smell in a VISUAL way that would come through a screen.
Strangers wore blindfolds and we had them describe their emotions as they smelled each other. It was remarkable how accurately they described physical attributes and innate characteristics of their unseen partner based simply upon their perfumed scent. (https://www.aaaa.org)
