映像への香り付加によるコンテンツ品質向上の取り組み

摘要

If we can produce image media that present odor stimuli to recreate smells along with their images, we can extend the possible range of expressions and enhance the realism of the sensations promoted by the images. In this paper, smells were coordinated with images using the olfactory display, and the psychology of the subject viewing the image was examined. The Semantic Differential (SD) method, based on a questionnaire, was used for the subjective evaluation of the subjects. The oculo-pupillary reflex and gaze detection method were used for the objective evaluation. We found that smell presentation reinforces both the realistic sensation and the understanding of the content of the image. Moreover, new display system able to emit smells from the inside of the screen and its applications are described.%映像の内容に適した香りを提示できれば，表現の幅が広がり，臨場感が向上することが期待できる．本文では，様々な香りを利用者の鼻先に提示する装置を用いて映像に香りを付け，その映像を見た被験者の心理を評価する方法について述べる．主観評価には，アンケートに基づいたSD法，客観評価には，瞳孔反射，視線検出などを用いた．香り提示は，映像の内容理解，臨場感の向上記憶量の増加などに効果があることを示す．また，画面から香りが放出される新しい表示装置，香り付き映像の応用についても触れる．
