ABSTRACT People mirror each other's body language as a way of bonding, seeking acceptance and creating rapport. Light Perfume is an interactive wearable system designed in the shape of a bangle that helps the wearer mirror their partner through lighting and olfactory cues. During a conversation, the Light Perfume system on each person's wrist uses multiple inputs from the surrounding environment to generate a synchronized output expression. This consists of a color and blinking frequency of light along with a perfume fragrance that is stimulated simultaneously from each system. The Light Perfume system was designed to foster social interactions and make people feel more empathy towards each other.
