초록

본 연구는 대형공간을 대상으로 시선추적 실험을 실시하고, 성별에 나타난 동공의 주시특성을 분석하였다. 시선추적 실험 시간의 흐름에서 생겨나는 동공변화를 분석함으로써 성별 주시행태를 객관적이면서도 과학적으로 분석할 수 있는 틀을 제시했다. 나아가 동공의 크기가 안정적으로 변하는 시간과 성별에 따른 차이를 정리하였는데 성별에 따른 시지각 정보 획득 시간의 특성을 발견할 수 있었으며 여자가 남자보다 1~2초 정도 늦게 관심과 흥미요소를 시각정보로서 받아들이기 시작한 것을 알 수 있었다. 초기 "1초${\rightarrow}$2초"에서 남자는 도약, 여자는 고정에서 동공크기가 확대되었다. 또한 고정 주시에 국한하여 성별 변화율을 보면 9초를 전환점으로 해서 9초 이하 시간에서는 여자가, 9초 이후 시간에서는 남자의 동공크기가 더 커졌다. 즉 1-8초 시간에서는 여자가, 10-15초 범위에서는 남자가 상대적으로 더 큰 동공확대를 통해 시지각 정보를 획득한 것으로 보인다. 하지만 주시시간의 시간의 변화에 따라 여자의 동공크기가 더 크게 확대된 것에서부터 여자의 경우가 일정 시간이 경과한 후에는 관심이나 흥미가 있는 요소를 더 많이 주시하려는 움직임이 활발했다.

The purpose of this study was to conduct eye-tracking experiments to target large spaces and to analyze the characteristics of pupil gaze by gender. By analyzing the change of pupil size in the eye-tracking experiment, we suggest a template for objective and scientific analyses of gender observation data. Additionally, based on the difference between gender and time to pupil size change, we noted the characteristic of time that gather the visual perception data information and showed that females attend to interesting elements of visual information one to two seconds slower than males. In the initial "$1sec{\rightarrow}2sec$", the pupil size has been increased in leap condition of male and in fixed condition of female. In addition, if condition limits to fixed observation to view the change rates on gender then the pupil size of female was larger than male before 9 seconds, while male's pupil size was larger after 9 seconds. This indicates that females obtain visual information through a relatively larger pupil size during the first 1-8 seconds after stimulus presentation, while males acquire it between 10-15 seconds after input. However, based on the result that the pupil size of female was larger than male on the change of observation time, the pupil size movement on female was energized to watch more interest element after a certain period of time.
