This paper presents an analysis on the interactive installation of “Scentgraphy”, which could compute, interpret, simulate and store scents behind scenes. It acts like an original camera or gramophone to capture and save pictorial memories. It not only enriches the interactive experiences, but also establishes a closer relationship with the combination of smell, vision and emotion. Meanwhile, Scentgraphy also provide an interesting interaction conducive for immersive experience of breathing aromatherapy. This project explores new experiences about the senses, sensory boundaries, storing and reproducing of the sense of smell. Based on ancient perfumery techniques, a closer bond is developed between memory and sense of smell. Scentgraphy project explored a way for computing, simulation, and telecommunication of odors by visual and olfactory conversion. This is a preliminary exploration on olfactory informationization, and this research ensures that the feasibility of converting visual and olfactory and digital odors can be spread and applied in media and information technology.
