This study analyzed the time to understand the space and the contents of information to be memorized in the indoor space. Understanding the space and examining the memory will not only provide the basic data on which visual activities occur in user's perceiving the designed space but also expand the activity range of interior designer. The summary of the study results is as follows: First, with respect to gender difference, the results showed that males grasped the space in a relatively shorter time. Females showed more concentrated distribution range than males. Second, as for the proper time by accumulative sum across time, the results showed that it increased continuously until V time zone(120~150 seconds), it decreased rapidly after the V zone, which indicated that the proper gazing time for the indoor space as the target of this study is less than 150 seconds(effective gazing time). Third, in terms of efficiency of information acquisition, the results suggested that "60~90 seconds" are the effective time for acquiring the greatest amount of information. Fourth, regarding the information acquisition method, males were approximately 4.1%~0.1% lower in the evaluation through phrase and image. The evaluation of subjects through phrase than image was connected to more accurate information acquisition.

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.

Objective: Mirror therapy is one of the promising methods suggested for the upper limb rehabilitation of stroke patients. While mirror therapy was presented to be effective in improving motor function of stroke patients, problems were raised as preceding studies had various methods in applying mirror therapy. Some studies even reported no effect in mirror therapy. Our supposition for the reason of such problems was a decrease of attention on the illusive image during mirror therapy of stroke patients, and we aimed to observe this. Design: A cross-sectional preliminary study. Methods: Three hemiplegic acute patients were recruited for the traditional mirror therapy. It lasted for 30 minutes, and 12 different tasks were asked to perform. All procedures were video-recorded, and Observer XT was used to analyse mirror-gazing time, gaze-distracted time, preparation time, frequency of mirror gazing, frequency of distraction, frequency of preparation for treatment. Results: Subjects spent an average of 4-5 minutes having instructions about the mirror therapy intervention (preparation duration), an average of 11 minutes watching the mirror during therapy (mirror-gazing duration), and the rest of 14-15 minutes looking around the environment (gaze-distracted duration). During the mirror therapy, the number of distracted moments (frequency of distraction) was eight times more than focusing on the mirror (frequency of mirror gazing). Conclusions: Once the patient looks at the mirror, it only lasts about 5 seconds on average. Thus, we confirmed that patients could not concentrate on the illusion during the session and therefore it may have affected the effectiveness of the therapy.

본 논문에서는 최근 광고효과 및 소비자 반응 측정 연구에 활발히 사용되고 있는 안구운동추적기법(Eye-movement tracking)을 이용하여, 광고 모델의 위치 및 시선 방향(정면/측면_그림정보/측면_언어정보)이 광고 태도 및 제품 구매 욕구, 브랜드 재인에 미치는 영향을 확인하고자 하였다. 지면 광고들 중 모델의 비중이 비교적 높으며, 간접적 설득 경로의 중요성이 비교적 크게 평가되는 화장품 지면 광고를 이용하여 20대 성인 남녀 36명에게 실험을 진행한 결과, 기존의 연구들에서 확인한 바와 같이 모델의 시선이 향하고 있는 광고 내 특정 요소(제품사진, 브랜드 등)에 대한 응시 시간(Fixation duration)이 길어지고 해당 영역에의 진입 시간(Entry time)이 빨라진다는 것을 확인할 수 있었다. 그러나 모델의 시선에 의한 주의 유도 효과가 광고태도 및 제품 구매 욕구에 바로 반영되지는 않았다. 모델이 좌측에 있는 경우에는 시선의 방향이정면일 때 제품 구매 욕구가 가장 높았으며, 모델이 우측에 있을 때는 측면_그림정보(제품사진) 에 시선이 향할 때 광고 태도가 높은 것으로 확인되었다. 그리고 안구운동 추적실험 이후 추가적으로 진행한 브랜드 재인 실험 결과에서는 모델의 시선이 제품 사진을 향하고 있을 때 브랜드재인도가 높게 측정되었으며, 모델이 왼쪽에 있을 때 유효하였다. 이상의 결과는 모델의 시선이고객의 주의를 특정한 영역으로 이끄는 주의 유도자(attentional guidance)로서의 역할을 수행하지만, 모델의 위치 및 시선이 머무는 대상에 따라서 그 효과의 방향성과 크기는 달라질 수 있다는 것을 시사한다. 따라서 궁극적으로 고객의 광고 태도 및 제품 구매 욕구를 향상시키기 위해서는 모델의 시선 방향 이외에도 모델의 위치 및 추가 구성 요인들에 대한 복합적인 고려가 필요할 것이다.

사진을 본다는 것은 프레임에 담긴 이미지를 지각하는 과정이다. 사진에 대하여 우리는 감각질료조직을 통해서만 작가의 의도에 접근할 수 있는 것이다. 우리가 사진을 바라볼 때 구체적으로 어떠한 방식으로 이미지를 보는지 검증해보기 위해서 로베르 두아노의 1948년 사진 '비뚫어진 관심'을 대상으로 실험을 실시하였다. 페미니즘 이론가인 매리 앤 도은이 이 사진에 대해 말한 것을 기초로 가설을 수립하고 분석하였다. 시선추적장치인 Tobii를 이용해서 사진을 바라보는 피험자들의 동공의 움직임을 기록함으로써 특정영역에 얼마나 오래 시선이 머무는지 측정하였다. 실험결과 사람들이 사진이미지를 바라볼 때 일정한 흐름을 통해 순차적으로 그것을 본다는 사실이 확인되었다. 동시에 프레임의 부분적 영역에 대하여 피험자들의 응시 강도가 달랐으며 피험자 집단마다에서도 편차가 있었다.

What is 'Art Theory'? In the western sense, the term poses a vague ambiguity, and in the eastern, it is rather an abstract and metaphysical concept. As for etymology, theory is derived from theoria and theoria from theoros. It refers to an act of viewing or seeing, of course not in a metaphysical sense. Plato understood it as 'eide'. During the time of Plotinus, theoria encompassed gazing at every possible reality, and this gazing, that is theoria, is closely related to reality as aunit that theoriacan perceive. However, we tend to distinguish, as other scientists of dualism have done, studio art from theory since a pre-modern approach to art has been particularly tuned to studio practice, set apart from theory. Therefore, in studio classes, students are expected to learn the subject based on the foundational curriculum methods such as medium, genre, technique:, rather than bringing out their own interpretations and discussing theories. As a result, students have become artists, who are not able to understand their own art. Art professors who conduct class in studio are required to proceed with specific 'theories' as well as 'intellectual reflections'. In this respect, this thesis presents poiesis and an idea of 'acting out'. Although art history and aesthetic theory tend to view art as a finished product, actual art-making and related theories should not only be acknowledged as 'completion' (finition) but also be accompanied by theoretic interpretations of the act itself and process. Accordingly, it is to accept and appreciate art as finished result in view of current theory and aesthetics thus boils down to aisthesis. Likewise, poietics starts from a point where an artist is related to studio and examines the 'work process' that extends as far as to the exact end of work. Through the study of such relationship, it is possible that theory understands 'studio' and 'process', and an artist can grant an independent meaning to studio where s/he pours her/his heart out creating a work of art. Theory is a study on artistic discovery thus should be equipped with functions that can accommodate fortuity, imitation, thinking, culture, and surrounding.
