Considering the recent increase of interest in the transmission of olfactory information alongside audio/visual information, the authors have developed an olfactory display, based on an inkjet printer mechanism, which emits scents for short periods of time and has high control and provides repeated stable pulse emissions of scents. By using pulse emission, the authors achieved chronological control for presentation of scents and were able to synchronize the pulse with human inspiration. Such synchronization is important because humans detect scents when they breathe in, inhaling scent molecules in the air. Applying pulse emission, the authors measured various human olfactory characteristics; furthermore, they developed scent presentation techniques to create perspective and to switch scents rapidly. This chapter introduces details about the olfactory display and scent presentation techniques using pulse ejection.
