Abstract	Abstract- Trials on the transmission of olfactory infor-mation together with audio/visual information are currently being conducted in the field of multimedia. However, the continuous emission of odors at high concentrations creates problems of olfactory adaptation and odors lingering in the air which do not match the changes in images over time. To overcome such problems, we applied olfactory pulse ejection to emit odor for very short periods of time. Humans perceive an odor when they breathe in and inhale smell molecules in the air. Therefore, it is important that the timing of pulse ejec-tion is synchronized with breathing. We have developed a breath sensor which detects inspiration, and in this study, we combined the use of this breath sensor with that of an olfac-tory display in order to establish a pulse ejection presentation system of odor synchronized with breathing. The results of an evaluation experiment showed that the system has a more than 90 % detection rate. In addition, a questionnaire survey of the users revealed that the system provides them with a con-tinuous sense of smell, avoiding the effects of adaptation and lingering odor. The use of the developed system is expected to make easier the synchronization of olfactory information transmitted together with audio/visual information.
