다크 모드에서 모바일 시각정보요소 카드의 시각적 인지도와 피로도 연구

Abstract

This study set out to analyze colors of high visual recognition and low visual fatigue at the tone level and their saturation scope in a mobile interface card fit for the dark mode in low illuminance, as well as propose a color scheme. For these purposes, the study analyzed color palettes for the dark mode in the Android system, then we tested color scheme samples of card elements in app layout to collect factors affecting visual recognition and fatigue. The survey answers with Likert and ordinal scales of the test were analyzed to prove study hypotheses. The findings show that the tone levels and colors had an effect on the visual recognition and fatigue items except for the items of color understanding and the items of composition understanding based on Likert scale survey. The analysis results identified a couple of colors of high visual recognition including yellow at the tone levels of 50, 100, and 300, blue at the tone levels of 50 and 300, and purple at the tone level of 100. Blue had low visual fatigue, and so did teal and purple at the tone level of 50. Both blue and purple had a low level of ocular discomfort like teal, which recorded lower visual fatigue than them. The analysis results identified purple and teal at the tone level of 100, and purple was found in all the items of visual fatigue. Yellow and teal were analyzed as the colors with the low visual fatigue at the tone level of 300. Yellow had a low level of ocular discomfort like blue, which recorded a lower level of ocular discomfort than yellow. Blue and yellow of high visual recognition were high in saturation, and teal and purple of low visual fatigue were lower in saturation than blue and yellow.
