Abstract

We developed the olfactory display to blend 8 component odors at any composition. The solenoid valVes controled by the algorithm of of the delta sigma modulation showed the sufficient capability. Then,we developed the system for presenting a movie together with scents. We actually made the content of the movie with scents and evaluated it using questionnaire survey. It was found that the scene with smell attracted the people's attention and, moreover, the contrast of the pleasant smell with the offensive one emphasized their attention. Furthermore, we established several guidelines to make the contents of the movies with scents.
