Analysis of Observation Characteristics revealed in the Visual Perception Process of A Street Space Image

가로 공간 이미지의 시각적 인지과정에 나타난 주시특성 분석

This study analyzed observation characteristics of the subjects revealed in the visual perception process of street space using the image of Guryongpo Modern Culture and History Street where was built to establish modern historical identity. For this study, an observation experiment was conducted using the eye tracker and for obtaining additional information of observation reasons, a retrospective think-aloud interview was carried out and the study findings are as follows: First, when the strength of observation was analyzed, all the subjects were found to look at the FR area(the front) more intensively than other areas. This means that in the space with a vanishing point, people tended to look at the area including the vanishing point, or the deepest point in the screen. Also, they observed the signboard or the left building facade with various elements like the signboard more actively than the right building facade showing the repetition of similar building facade form elements. Second, the frequency of conscious observation was analyzed only using the data which showed 6 consecutive observations of some point. As the result, the strength of observation and the frequency of conscious observation were highly different in east area and the frequency of conscious observation had the highest mean value. This implies that there was a convergent exploration in the left and right building lower areas. Third, additional information about observation data was acquired through a retrospective think-aloud interview. As the result, the main reasons of the subjects for looking at each area according to the observation purposes were 'interest element exploration' and 'disparate element exploration'. When the subjects were asked about the observation elements which remained in their memory, among the 'interest elements', the window showed the highest frequency(85.3%) and it was followed by the wooden panel(67.6%), the sliding door(64.7%) and the plastered wall(50%). Among the 'disparate elements', the telephone pole showed the highest frequency(47.1%) and it was followed by the mailbox(44.1%) and the rainwater tank(26.5%).
