초록

본 논문은 360도 동영상과 감각효과(Sensorial Effects)가 피실험자의 몰입도, 만족도, 실재감에 미치는 영향을 측정하기 위한 사용자 경험(Quality of Experience: QoE) 평가 실험 방법을 제안한다. 피실험자는 발향장치가 부착된 헤드 마운티드 디스플레이(Head Mounted Display: HMD)를 착용한 상태에서 감각효과가 동반된 360도 동영상을 경험한 후, 몰입도, 만족도, 실재감에 대한 설문에 응답한다. 응답 분석 결과 제안된 실험방법이 360도 VR 동영상과 감각효과에 대한 피실험자의 몰입도, 만족도, 실재감 등을 측정하기에 적합한 실험 방법임을 확인하였다. 반면, 360도 동영상을 시청하는 도중 비교 실험을 위한 회색 화면을 삽입하게 되면 몰입도와 실재감에 상당한 저하를 일으키는 것으로 파악되었다.

This paper proposes a Quality of Experience (QoE) evaluation experiment to measure the effects of 360-degree video and sensory effects on the subject's degree of immersion, satisfaction, and sense of presence. The test subject responds to a questionnaire about the degree of immersion, satisfaction, and sense of presence after experiencing a 360-degree video accompanied by sensory effects while wearing a head-mounted display (HMD) with a scent diffusion device. As a result of the response analysis, it was confirmed that the proposed experimental method is suitable for measuring the subject's degree of immersion, satisfaction, and sense of presence about 360-degree video and sensory effects. On the other hand, inserting a gray screen for comparison experiments while watching a 360-degree video was found to cause a significant decrease in immersion and realism.
