Your sense of smell is unique, and directly connected to your brain's emotion, arousal, and memory centers. In SmellSpace you will first smell odors and rate them. We will then generate your smell-based identity. You can then view smell-based predictions on your personality, and view smell-based matching scores between you and your friends, or let SmellSpace suggest new friends based on smell-match. Our research suggests that couples with high smell-match scores have good relationships.

All the odors used in SmellSpace are used in perfumery and scientific experiments with human subjects, and are considered perfectly safe at these concentrations. That said, as detailed in the terms of use, if you are pregnant, or suffer from any medical condition that may prevent you from sniffing several odors in succession, please do not participate.
