Method for identifying aromas using adjective characteristics to enhance the reality of visual images

Abstract

Some works have suggested that certain aromas can enhance the reality of visual images of distant locations on the basis of the CONTENTS constituting the images; and these CONTENTS can be referred to using nouns. Aromatic materials need to be classified in order to identify the ones corresponding to each CONTENT. In this paper, we conducted two experiments. The subjects first rated the extent to which the aromas enhanced the reality of the visual images. CONTENTS of these visual images were different kinds of trees. Nine aromatic materials received high ratings. The subjects then rated the aromas using adjectives. The nine aromatic materials were classified into two clusters on the basis of the adjectives. These results showed that the use of adjectives to describe aromas is practical for such a classification.
