Essence Video Showcase: Olfactory Interfaces for Unconscious Influence.

The sense of smell is perhaps the most pervasive of all senses, but it is also one of the least understood and least exploited in HCI. We present Essence, the first olfactory computational necklace that can be remotely controlled through a smartphone and can vary the intensity and frequency of the released scent based on biometric or contextual data. We present a set of applications for this type of technology as well as the main components of the olfactory display. This video accompanies our CHI full paper [1].
