Abstract

This paper's objective is to investigate the display fatigue quantitatively according to watching 2D and 3D videos on the display. Though it has been known commonly that display fatigue by 3D is greater than one by 2D, there have been few researches with an aim to measure display fatigue scientifically. Flicker fusion frequency and cybersickness degree were measured before/after sixteen subjects(Male 8, Female 8) watch the 2D, 3D images. Two dependent variables affected by 2D and 3D videos were analyzed and compared statistically based on scientific evidences and researches. 3D showed a value 4 times as much as 2D in cybersickness increase rate, and the reduction rate of 3D was 2 times as much as that of 2D.

본 논문의 목적은 운용자가 2D와 3D 영상을 주시할 경우 영상피로를 정량적으로 비교하는 것이다. 16명의 20대 남 여가 2D와 3D 영상을 10분간 관람을 한 후, 관람 전과 후의 Flicker Fusion Frequency(FFF)와 Cyversickness가 측정되었다. 관람 전과 후의 두 종속변수를 비교함으로써 정량적으로 3D가 2D에 비해 어느 정도 영상피로를 발생시키는지를 이론적 고찰과 함께 과학적인 기기와 방법으로 측정하였다. 주관적인 척도인 Cybersickness 증가율은 2D에 비해서 3D가 4배, FFF 감소율은 3D가 2D에 비해 2배 높은 결과를 보였다. 본 연구는 일반적으로 3D 영상이 2D 영상에 비해 영상피로를 크게 유발함을 과학적인 방법과 객관적인 데이터로 증명했다는데 의의가 있다.
