초록

목적: 모니터 글자 색상에 따른 가독성을 측정하여, 모니터와 전자미디어 사용에서 안정피로를 감소시킬 수 있는 데이터를 제공하기 위한 기초 연구이다. 방법: 색각이상이 없으며 최대교정시력 1.0 이상의 피검자 50명(평균연령 $22.93{\pm}1.68$)을 대상으로 읽기속도 검사를 163개 단어 중 123개 이상의 단어를 읽은 피검자를 선정하였다. 모니터는 배경색을 white로 통일하였으며, 글자 색상은 black, blue, red, yellow 4가지 색상으로 가독성을 측정하였다. 결과: 글자 색상 Black, Blue, Red, Yellow인 경우 평균가독시간은 각각 41.89초, 42.89초, 45.32초, 56.28초로 측정되었다. 독서오류에서는 Black 1.94개, Blue 2.74개, Red 3.36개, Yellow 5.14개로 측정되었다. 평균고정시간에서는 Black 0.25초, Blue 0.26초, Red 0.27초, Yellow 0.32초로 측정되었다. 결론: 본 연구에서 가독성을 평가하는 항목인 가독시간, 독서오류, 평균고정시간에서 모두 Black, Blue, Red, Yellow순으로 가독성이 감소하는 경향을 보였다.

Purpose: This study will be a basic research providing data which can reduce eye strain using monitor and electric media by measuring legibility of text color on monitor. Methods: Total experimental subjects who don't have color anomaly and best corrected visual acuity was over 1.0 were 50 and their mean age was $22.83{\pm}1.47$. Reading speed test were carried out with 163 words and subjects who could read over 123 words were selected for legibility examination. Monitor background color was white and letter colors were black, blue, red, and yellow for the legibility examination. Results: In case of text color of black, blue, red, and yellow, Event duration(sec) was measured to 41.89, 42.89, 45.32, and 56.28, respevtively, and reading error (number) was measured to 1.94, 2.74, 3.36, and 5.14. Average of fixation duration(sec) was measured to 0.25, 0.26, 0.27, and 0.32. Conclusions: In this paper, event Duration, reading error and average of fixation duration which can measure the legibility was reduced in a sequence of black blue, red, and yellow.
