Although technologies for vision and audition are highly advanced, digital technology for olfaction still remains at an early stage. However, our daily lives will change significantly if digital scent technology is easily available. In this paper, we provide an overview of digital scent technology. Then, the fundamental digital technologies for olfaction, i.e. odor sensing, odor reproduction, scent creation and odor presentation are reviewed. This is modernized cheminformatics on the platform of current information technology. Finally, the future perspective is discussed.
