The authors propose using interactive and multisensory interfaces to design user behavior change. For this purpose, they used coauthor Nikolic's interactive art installation InnerBody , created to provoke health-care-related behavioral changes by arousing death anxiety. Visitors are invited to undertake a (fake) medical examination by interacting with the installation's human heart-shaped interface. Research outcomes are presented based on visitors' observations and participant responses in interviews after interacting with the installation.

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.
