Abstract

There has been growing academic interest in revealing the effect of 3D stereoscopic displays, mostly based on the assumption that 3D would enhance the media user's psychological experiences. A 2(Display: 2D, 3D) x 2(Arousal: High, Low) x2(Valence: Positive, Negative) within-between subject experimental design, including both psychophysiological and self-report measurements, was employed to investigate if valence and arousal of the media content interact with the 3D stereo display. The results confirmed that 3D stereo significantly enhances the viewer's skin conductance level, while no meaningful difference for HR was found across the experimental conditions. The viewer's recall memory did not differ depending on the display type either. However, the viewer experienced a greater level of presence and liking of the content when the negative content was displayed in 3D stereo in comparison with the positive content. The practical implications of the results are further discussed.

영상 콘텐츠가 2D와 3D의 다른 차원에서 재현되었을 때 수용자의 심리적 반응에는 어떠한 차이가 있는지 보다 종합적으로 알아보기 위하여 본 연구는 유인가와 각성과 같은 콘텐츠의 내용적 특성이 영상의 입체성과 연계되어 수용자의 자기보고식(self-report) 설문과 수용자의 생리심리학적(psychophysiology) 반응에 미치는 효과를 살펴보았다. 연구 결과, 동일한 영상이라도 3D로 시청하였을 때 수용자의 피부전도계수(SCL)는 유의미하게 높았던 반면, 심장박동(HR)의 경우 유의미한 차이를 나타내지 않았다. 또한 3D 영상에서 수용자의 실재감 인식이 더 높게 나타나는 것으로 분석되었으나, 인지적 정보처리를 표식하는 회상기억에서 입체성에 따른 효과는 발견되지 않았다. 흥미롭게도 수용자의 실재감과 이용의사에서 콘텐츠의 내용적 특성 중 유인가가 입체성과 상호작용효과를 보였다. 부정적인 콘텐츠는 3D 영상에서 긍정적인 콘텐츠는 2D 영상에서 보다 높은 실재감과 이용의사를 이끌어내는 것으로 나타났다. 3D 영상 산업의 발전을 위해 영상의 입체성과 콘텐츠의 속성이 가지는 상호관계에 대한 논의가 지속적으로 이루어져야 할 것이다.
