The main purpose of this research is to develop the methodology of objective evaluation of clothing appearance by eye movement analysis. The visual clothing items used in this study were skirt, one-piece, pants and shirt with the style variation of silhouette and details. By observing eye movement during visual evaluation of clothing, we can achieve the basic fixation data of eye movement. Moreover, we developed the Matlab program to extract the fixation coordinate and number of eye fixation on each part of the clothing item. As results, there were differences in the duration of fixation time for each item and the fixation time was not different by styles within a clothing item. However, we could find differences in the fixation time within a style, in other words, we could select the important parts of the clothing by observing the fixation time in a certain clothing item. It is also noted that time required in visual information processing differs depending on the item, and there was a region which contain more information independent with styles in the same item. By developing the objective method of visual evaluation that correspond to human's visual information processing, the results are expected to be applied in the retrieval program in internet shopping mall or in the development of contents for advertisement of clothing.

This study has performed a comparative analysis between groups based on Time To First Fixation, Fixation Duration, Fixation Count and Total Visit Duration, which are eye-tracking analysis indicators on what visual attention is shown compared to the e-magazine produced as regular images related to e-magazines in which experiment subjects have applied cinemagraph images as eye tracking research on the e-magazine produced with cinemagraph images and e-magazines produced with regular images. The experiment sample used e-magazines composed of nine pages while AOI (area of interest) has been set up on each page by classifying image and text regions. A combined 30 people took part in the experiment, which was performed by randomly assigning 15 to the experiment group and 15 to the control group. According to the results of the analysis, the experiment group recorded a shorter time than the control group on the e-magazine produced with cinemagraph images through Time To First Fixation. Though no significant difference was found between the experiment and control groups in Fixation Duration, a substantial difference did appear between Fixation Duration and Total Visit Duration.

The main purpose of this study was to examine elementary teachers' visual attention that appears in science textbook tables. This paper proposed that teachers' cognitive effectiveness can be different by the presence or absence of the title of tables. The eye fixation data of participants are collected by the eye tracker apparatus. Participants in this study were 10 elementary school teachers and the table on the 2007 revised science textbooks were selected as experimental stimuli. Information about eye-fixations are recorded when subjects are given 4 tables by eye tracker. Eye-fixation time as well as the ratio and the number of fixation can be obtained by using the eye tracker but also we can acquire a significant conclusion through these outcomes. As the result of the experiment, it took less time to interpret in the presence of the title than in the absence of it. However, this result is only effective only for the interpretation of simple stimulus; the presence of title does not influence on fixation time in the analysis of complicated stimulation. This study showed that it is better to insult the title in the tables because it helps teachers to recognize contents of the tables effectively.

디지털 컨버전스 제품은 복잡한 정보 구조로 인한 인지적 과부하로 메뉴로 부터 효과적인 정보 인출의 방해를 초래하고 있다. 이러한 인지적 과부하를 완화하기 위해서 현재까지 크게 두 가지 방법(메뉴의 폭과 깊이에 관련된 물리적 방법과 메뉴 타이틀에 관련된 어의적 방법)을 사용하여 효과적인 메뉴구조를 만들기 위하여 노력하여 왔다. 본 연구는 visual search에 수반되는 Fixation과 Fixation Duration을 사용한 또 다른 어의적 방법론을 제안하여 메뉴구조 설계 방법으로서의 효능을 입증하고자 한다. 특히, Fixation은 인간의 인지 모델에 따라 자동적으로 이루어지기 때문에 Fixation을 통해 정보 구조와 인지 모델간의 일치 여부를 파악할 수 있으므로 인지적으로 잘 설계된 메뉴 구조는 Fixation 수와 Duration이 잘못 설계된 메뉴구조보다 적다는 가설이 성립된다. 이러한 가설의 검정을 위하여 본 연구에서는 Eye-Tracking 장비를 사용하여 메뉴 수정 전 후의 Fixation 수와 Duration을 측정하여 비교하였다. 그 결과 수정 후의 Fixation 수와 Duration이 유의하게 감소됨으로서 수정 후의 메뉴구조가 수정 전보다 효과적인 메뉴구조임을 알 수 있다. 다시 말해서 본 연구에서 제안한 visual search에 수반되는 Fixation과 Fixation Duration을 사용한 메뉴구조 설계 방법론이 효과적인 방법이라는 것이 증명되었다.

This study aimed to conduct an eye-tracking experiment carried with facade images as a medium and to do research on 'the interest of the eyes' resulted from people's gazing phenomena. This study secured gazing data which appeared according to visual response and analyzed gazing phenomena to find the basic theory of 'the interest of the eyes' as a methodological role, which consumer interest and attention could be grafted when a plan and a design for space design was made. Data terms used in eye-tracking backgrounds and the movement of the eyes were investigated in literature review. Twenty (20) facade images were selected through a case study to get experimental stimuli for the related experiment. Thirty (30) subjects (men and women) suitable for the experiment were recruited to conduct an eye-tracking experiment. After the experiment, five (5) areas were set up in the facade image to identify the focus level of interest and attention. The level of interest and focus was connected to the interest of the eyes. The analysis to study the interest of the eyes was based on nine (9) items such as sequence, entry time, dwell time, hit ratio, revisits, revisitors, average fixation, first fixation and fixation count. Through gaze analysis, the following conclusion was drawn about the 'interest level of sight' for gaze frequency. The interest level can be interpreted to be higher for faster sequence, shorter entry time, longer all fixation(ms) for dwell time, faster all saccade(%), higher hit ratio, more revisits, more revisitors, longer average fixation, faster and longer first fixation, and more fixation count, and the person can be said to have felt interest faster and/or more.

As measuring visual behavior by utilize eye-tracker, this study examines whether consumer concentrates on visual attention with certain object and measures visual behavior with fixation number, fixation duration, the first fixation, which are visual attention pattern of consumer about Mannequin, hanger, shelve as props of display advertising effect on clothing store. It has experimental purpose to recognize relationships in terms of regardless, appropriateness, purchase intention. During display of clothing store, first experimental consequence to measure visual behavior on consumer did appear to allocate more cautions than other props. Second, in terms of relationships with regardless, appropriateness, purchase intention from consumer, each fixation pattern about consumer's fixation number, fixation duration, the first fixation was confirmed that there is meaningful correlation with each other. Accordingly, as advertising effect of mannequin makes consumer to concentrate more visually cautious, it is translated that high favor about display product with mannequin has positive role on purchase intention. Also, there is a purpose that higher feasibility on study result provides practical point on clothing store's display marketing strategy of corporation.

This research is to analyze the spatial information search features which shown by Eye fixation and movement and conducted eye tracking experiment for targeting sports shop spatial images which it are same but looks different. This is able to find out the eye movement feature according to placement of goods from the eye movement and movement distance of spatial visitor, and the result can be defined as following. First, the whole original-reverse left / right images have a higher number of observations in the [IN] area than in the [OUT] area. This is because after eye taking high observations in LA area of [IN] have been jump-over [OUT], performed search activities in low eye fixation without high eye fixation. Second, there was a difference in the frequency of the observation data as the composition of the images changed. The original image has been often fixed the eyes in LA area, and the one that has been observed for a long time is reverse left / right image. Also, fixation point was shown higher at the reverse left / right image as jump-over from [OUT] area to [IN] area. If LA area seen as reverse left / right image, it is located in right-hand side. The case where the dominant area is on the right side has a characteristic that the eye fixation is longer. This can be understand that the arrangement of products for attract the customer's attention in the commercial space might be more effective when it is on the right side. Third, the moving distance(IN ${\rightarrow}$ OUT) of the sight pointed to external from LA area was long in the both original-reverse left / right images, but it is no relation with search direction([IN${\rightarrow}$OUT] [IN${\rightarrow}$OUT]) of the sight. In other words, the sight that entered in LA area can be seen as visual perception activity for re-searching after big jump-over, in the case go in to outward (OUT area) after searching for more than certain time. The fact that the moving distance of eye is relatively short in the [IN ${\rightarrow}$ OUT] process considered as that the gaze that stays outside the LA area naturally enters in to LA area.

In this study, measuring eye movements with E.O.G. to targets beyond 20$^{\circ}$ from fixation point, results are as follows. (1) When the eyes turn toward targets of more than 20$^{\circ}$ eccentricity, the first saccadic eye movement falls short of the target. The presence of image of the target off the fovea(visual error signal) subsequent to such an undershoot elicits, after short interval, corrective saccadic eye movements(usually one) which place the image of the target on the fovea. (2) There are different programming modes at retina for eye movement to targets within and beyond 20$^{\circ}$ from the fixation point. (3) Saccadic system, preparing the direction and amplitude of eye movement completes the corrective saccadic eye movements. (4) Distribution of latency and intersaccadic interval(I.S.I.)are frequently multi modal, with a seperation between modes of 25[msec]. (5) There are two types of saccadic eye movements for the double-step targets. This fact suggests that the visual information is sampled stochastically. (6) The new model of saccadic system including the dissociation of visual functions dependent on retinal eccentricity is required.

The purpose of this research is to analyze characteristics of street elements when pedestrians have a view in the street. The research was utilized eye-tracking experiment and two times survey before and after experiment. The experiment is composed as follows. The data collection was conducted two days period from March 30 to 31, 2017. There were 43 participants who were all male and undergraduate students. In the data recording, the stimulus image was presented 65 seconds on a 23-inch monitor. Prior to analyzing data, the images were represented into five elements of AOI(area of interest). The fixation rate was divided by a period such as 'fixation time' and 'fixation count' parameters. The results were additionally obtained by linking analysis with the area ratio of AOI, time series analysis, and questionnaire. First of all, both building signs and advertisement standing boards draws attentions in participants. From a comparison between fixation rate and survey, the data have negative perspective view. Second, the advertisement standing boards are more eye-catching than other elements regardless of AOI size. It shows the priority of elements what should be developed in the environment. Third, the pavement is rarely seen in the fixation rate. Fourth, the trees are not a long frequency but viewed as a positive element. People want to keep the natural site in the street. In summative research, this method of extracting eye movement data would be provided a foundation data for developing streetscape plan based on scientific factors.
