This study tried to analyze the composition relation of a form in Korean traditional architecture through the viewpoint of visual perception and through the analysis by the number and quantity, and to analyze and implied relationship between the form composition of the traditional architecture and the principles of perception in the contemporary viewpoint by reviewing all the aspects on how to be perceived. Architecture has been studied in the relationship of the form and the space both existing together, so has Korean traditional architecture. But in the present condition with the construction norm of the traditional architecture-well known for its beauty in shape-and documents not existing, so that the study on Korean traditional architecture in the aspects of the form has to be undertaken on the basis of researching the existing architecture theoretically and architecture-relating documents actually. Therefore this study tries to review the mathematical principle and the ideological background of those days, and the attitude of ancestors treatment to the architecture by researching the existing architectural figure. Using mathematical analysis method with the basis of the above synthetically, this study aims at the analysis in the aspects of the visual perception on the form of Korea an traditional architecture.

가상 환경 속의 참여자는 가상 객체와의 상호작용을 통해 실제와는 다른 몰입감과 인지적 경험을 하게 된다. 최근에는 누구나 쉽고 저렴하게 가상 환경을 경험할 수 있는 스마트폰 기반의 머리 착용형 디스플레이(HMD)들과 광시야각의 고품질 HMD들도 폭넓게 상용화되고 있다. 하지만, HMD의 근본적 수렴-초점조절 불일치 구조와 현실 세계에서 학습된 인지 차이로 인한 어지러움, 메스꺼움 등의 부작용은 여전히 극복해야 할 문제로 남아 있다. 본 연구는 여러 인지 차이 요인 중 가상 객체와의 상호작용에 중요한 일관된 크기 인지에 초점을 두고 있다. 실제 환경에서 물체의 크기 인지에 영향을 주는 시각도가 가상 환경에서도 주된 요인인지 검증하고, 그 시각도와 가상 객체 크기 인지에 도움을 주는 환경 구성 요소인 그림자와 격자 표현과의 관계를 분석한다. 회귀 분석 결과 시야각이 작은 HMD 환경에서 시각도는 크기 인지에 영향을 미치며, 그림자와 격자 표현도 크기 인지와 유의미한 결과를 얻었다.

The human scale of the interior space of a korean traditional residence is normally user-friendly. And this aspect is reinterpreted and implemented in the modern structure. While our conscious awareness has become greatly westernized through the east-west exchanges, the interior of the traditional Korean residence has always reflected the people and their daily lives of the time. In this study, an attempt has been made to identify the aesthetic characteristics of the inner space elements through the analysis of visual perception inside a Korean traditional upper class residence, kangreung Sunkyojang, designated as the 5th Cultural Information Material with regards to the inherent philosophy and human scale that influenced the emotions of the Korean people. The different parts of the interior space of Anchae, and the Symmetrical of Formal, Balance of the walls give a sense of calmness, and the ornaments are used to give gaiety. The ceiling of Yeolwhadang hall give an energetic feeling and pillare are used to enhance spaciousness. In Whalejeong, by making use of similar and continuous lines, the light and darkness was controlled and the link with nature has been emphasized. Different decorations used reflect scholarly spirit.

As it gets nearer to the modern society, social and cultural situations are changing and the spatial form of public space is changing into the complex structure where it is interlinked with each other diversely. In particular, as the development of large-scale complex spreads nationwide, the form of complex commercial space assuming the nature of malls appears prominently. In such a large-scale complex commercial space, the diverse visual elements make the environment difficult to be perceived. Like this, the attention in the commercial space where a variety of visual stimuli are in the presence, is important element, so the plan of VP(visual presentation) is needed for effectively selecting or inducing the space. Thus, in this study, human visual and perception process will be reviewed and a method to evaluate the attention will be proposed. Also, the attention of each stores in the complex commercial spaces will be evaluated to propose the indicators for resonable spatial panning in the future.

The purpose of this study was to compare the efficiency of visual perception and impulse according to the three types of Taekwondo players to be able to supply an efficient training method, for this a total of 12 representative Taekwondo players of the Korean National team, 4 poomsae players, 4 kyokpa players and 4 kyorugi players weighting between 68 to 74 kg, and the results from the motion analysis system, eye tracker and Electronic hogu are as follows. For the visual perceptual function, the total body reaction time was slowest for the kyokpa group, and for the visible reaction and vision fixation time was longest of the poomsae group, while the performance movement was fastest for the kyorugi group. As for description of the two kicking motions dollyo chagi and dolgae chagi the longer visual fixation helps the accuracy of the kick. In conclusion, as there was a difference between the groups, this information could help to train the visual perception of players according to what event they are participating in.

This research aims to identify the relationship between visual perception and emotion by the types of fear responses elicited from warning images on cigarette packages as well as the effectiveness of the size of such images through questionnaires and eye-tracking experiments with twenty university students from the colleges based in Busan. The research distinguished and analyzed the warning images as rational appeals and emotional appeals by the degree of fear and disgust and the result concurred with the research conclusions of Maynard that people would naturally avoid eye contact when presented with a warning image on cigarette packages. Also, eye avoidance was highly identified with larger (75%) warning images. While the previous research mostly adopted the self-rated validation method, this research tried to make the methodology more objective by adopting both questionnaires and eye-tracking experiments. Through this research, authors contribute to finding effective warning images on cigarette packages in a way to increase public awareness of the dangers of smoking and discourage smoking. Further research is recommended to explore the effectiveness of using explicit images on cigarette packages by the types of smokers such as heavy smokers, normal smokers, and non-smokers.

The accurate error size and discrimination region in the perception of depth amount from 3-dimensional images by the human visual system will be the basic data for the utilization and application of the binocular 3- eimensional image system. This paper is focused on studying the accuracy of the depth amount perceived from 3- dimensional images by the human visual system. From the performed experiment, the following results have been obtained: (1) The depth amount perceived from the binocular 3- dimensional images has been displayed by a proper scale of distance, and found to be imprecise and also have a large variance. (2) In utilizing the binocular 3-dimensional image system, it seems more appropriate to make the images viewed outward rather than inward from the screen in the regard of error and variance. (3) The binocular 3-dimensional image system can be effectively applied to displaying unreal space, for example, the layout of room in design, from the viewpoint of perception characteristics of depth amount.
