Abstract

Technologies for video reality (e.g., 3D displays, vibration, surround sound, etc.) utilize various sensory input and many of them are now commercialized. However, when it comes to the use of olfaction for video reality, there has not been much progress in both practical and academic respects. Because olfactory sense is tightly associated with human emotion, proper use of this sense is expected to help to achieve a high degree of video reality. This research tested the effects of a video's color-temperature related scent on reality improvement when the video does not have apparent object (e.g., coffee, flower, etc.) which suggest specific smell. To this end, we had participants to rate 48 scents based on a color-temperature scale of 1,500K (warm)-15,000K (cold) and chose 8 scents (4 warm scents, 4 cold scents) which showed clear correspondence with warm or cold color-temperatures (Expt. 1). And then after applying warm (3,000K), neutral (6,500K), or cold (14,000K) color-temperatures to images or videos, we presented warm or cold scents to participants while they rate reality improvement on a 7-point scale depending on relatedness of scent vs. color-temperature (related, unrelated, neutral) (Expts. 2-3). The results showed that participants experienced greater reality when scent and color-temperature was related than when they were unrelated or neutral. This research has important practical implications in demonstrating the possibility that provision of color-temperature related scent improves video reality even when there are no concrete objects that suggest specific olfactory information.

3D 디스플레이, 진동, 서라운드 음향 등 다양한 감각자극을 활용한 영상실감 기술이 상용화되었으나, 후각을 사용한 영상의 실감향상에 대해서는 아직 뚜렷한 진전이 없다. 후각은 인간의 정서와 강하게 연합되어 있기 때문에, 이를 잘 활용한다면 높은 수준의 실감향상이 가능할 것으로 기대할 수 있다. 본 연구는 영상에 냄새를 암시하는 뚜렷한 대상(커피, 꽃 등)이 존재하지 않을 때, 영상의 색온도와 관련이 높은 향의 제시가 영상의 실감향상에 미치는 효과를 검증하였다. 이를 위해 먼저 48가지 향을 수집하여 1,500K (따뜻한) ~ 15,000K (차가운)의 색온도 척도를 통해 향과 색온도의 매칭을 실시하여, 따뜻한 혹은 차가운 색온도와 뚜렷한 매칭을 보인 향 8개 (따뜻한 향 4개, 차가운 향 4개)를 선정하였다 (실험 1). 이를 토대로 이미지와 영상에 따뜻한 (3,000K), 중립적인 (6,500K) 혹은 차가운 (14,000K) 색온도를 적용한 후, 따뜻한 혹은 차가운 향을 제시하여 향과 색온도의 일치도 (일치, 불일치, 중립)에 따라 실감이 얼마나 향상되는지 참가자들에게 7점 척도로 평정하게 하였다 (실험 2-3). 그 결과 향과 색온도가 일치할 때 참가자들은 불일치하거나 중립적일 때 보다 이미지와 영상의 실감을 더 높게 평가하였다. 본 연구는 영상에 후각 정보를 가진 구체적 대상이 없을 때에도 색온도 감성과 일치하는 향을 제공함으로써 영상실감 향상이 가능하다는 것을 보여준다는 점에서 중요한 실용적 가치가 있다.
