Smell of faces
This unique, ever-changing pattern is visualized in a facial composite. This is how it works: when a person approaches the analyzer, sniffing tubes “sniff” him, then gas analyzers process the information, which then passes to a computer program that translate air composition data into data concerning the shape and position of facial features (the components of a facial composite). As a result, a person sees a face of their smell that is conditional, in no way related to their actual physical appearance.
