Abstract

In this study, we investigated the effect of peripheral blur on binocular fusion to resolve binocular fusion failure which is one of the 3D visual fatigues in the perspective of human visual system. With stimulus having discrete disparity change, binocular fusion failure rate for target stimulus having crossed and uncrossed disparity decreased. And target stimulus having continuous disparity also required relatively larger binocular disparity when peripheral blur was presented with target stimulus rather than when peripheral blur was not presented. These results imply that peripheral blur facilitated binocular fusion in the situation of binocular disparity change, and suggest that considering the characteristics of human three-dimensional visual systems, manipulating 3D contents can improve visual discomfort caused by binocular displays at low costs.

본 연구는 입체 영상을 시청할 때 시각적 불편감 중 하나로 언급되는 양안융합 실패를 인간의 삼차원 지각 시스템 관점에서 해결하기 위하여 주변 시야의 상 흐림이 양안융합에 미치는 영향을 검증하였다. 단속적 양안 시차 변화를 가지는 자극을 제시할 때 주변 시야의 상 흐림이 제시되는 경우 교차 및 비교차 시차를 가지는 표적자극에 대한 양안융합 실패율이 감소하였다. 또한 연속적 양안 시차 변화를 가지는 자극 역시 주변시야의 상 흐림이 제시되지 않을 때에 비하여 상 흐림이 제시되는 경우에 비교차시차를 가지는 표적자극 중 양안융합 실패를 유발하는 데에 상대적으로 더 큰 양안 시차가 요구되었다. 이와 같은 결과는 주변시야 상 흐림이 양안 시차 변화상황에서 양안융합을 촉진함을 의미하며, 인간의 3차원 시각 시스템의 특성을 고려하여 자극을 조작하는 것이 낮은 비용으로 양안식 디스플레이가 유발하는 시각적 불편감을 개선할 수 있음을 시사한다.
