In the West, of the body's five senses sight is considered the most important but Ocular-centralistic thinking contains many issues. Privileging the subject and inhibiting interaction with the other senses, Ocular-centrism limits the experience of the world to the visual area. However, experiences can be understood as 'touching' various forms and are related to touch. With the heightened interest in the multi-sensuous side of the body contrary to Ocular-centrism, the intervention of the body in the external space has become an important issue in modern landscape architecture. This study explores the possibility of the haptic perception system that causes the active experience of a subject. Haptic perception plays a catalytic role leading an active experience of the subject and the subject experiences a sense of place through such haptic perception. By revealing what was known through the sense of touch through the concurrency and interaction of the various senses, haptic perception draws active participation The haptic perception system has been studied in various fields but has not been studied in the field of landscape architecture. Thus, this study discusses the aspect of haptic perception limited to landscape architecture shown before modernism. In a discussion on haptic perception, the concept of haptic perception is clarified through previous study reviews and literature and the characteristics of haptic perception are derived. Then, the problems of the Ocular-centrism system and the need for haptic perception are discussed. In the historical development process of haptic perception, the change process of the scopic regime is examined chronologically and the ways in which Ocular-centralistic thinking and anti-Ocular-centralistic thinking have been projected on the architecture and landscape architecture of each age are studied via literature and cases studies. The impact of the scopic regime on the landscape architecture field in the historical change process is examined.

인간의 시각 시스템은 선택적 주의 집중에 의해 시각 수용체로 도달되는 많은 물체들 중에서 필요한 정보만을 추출하여 원하는 작업을 수행한다. Itti와 Koch는 시각적 주의를 제어할 수 있는, 신경계를 모방한 계산적 모델을 제안하였으나 조명환경에 고정적인 saliency map을 구성하였다. 따라서, 본 논문에서는 영상에서 ROI(region of interest)을 탐지하기 위한 조명환경에 적응적인 saliency map 모델을 구성하는 기법을 제시한다. 변화하는 환경에서 원하는 특징을 부각시키기 위하여 상황에 적응적인 동적 가중치를 부여한다. 동적 가중치는 conspicuity map에 S.K. Chang이 제안한 PIM(Picture Information Measure)을 적용시켜 정보량을 측정한 후, 이에 따라 정규화된 값을 부여함으로써 구현한다. 제안하는 조명환경에 강인한 적응적인 saliency map 모델 구현의 성능을 얼굴검출 실험을 통하여 검증하였다.

본 논문에서는 동영상을 대상으로 하는 기존의 시각주의 시스템의 성능을 향상시킨 새로운 시스템에 대하여 설명한다. 제안하는 시스템은 기존의 시스템이 가지고 있던 한계점인 서로 반대되는 특징을 가지는 색상에서 하나의 특징만을 고정적으로 선택하던 것을 극복하여, 서로 반대되는 특징 중 현저항이 더 높은 색상 특징을 선택하여 입력 들어오는 영상에 적응적인 현저항 추출을 하였다. 도한 시간 현저항 정보를 추가적으로 고려할 수 있도록 하여 동영상에 대한 처리도 가능하도록 하였고, 성능 평가 시 인간을 대상으로 한 설문 조사 실험을 추가하여 보다 인간의 시각 인식과 유사한 시스템임을 증명하였다.

CGI not only performed a crucial role to make cinema and animation evolved into digital cinema and digital animation but also CGI, an important visual format, settled realism-centric spectacle image culture in public commercial cinema and animation. The fact that CGI visual format could be structuralized in three different view points is discovered through Iconicity, photorealism, verisimilitude, uncanny valley, hyperrealism, and spectacular realism discourse research which explain image culture. First, a formative viewpoint that comes up in an iconic difference between drawing and photograph. Secondly, a cognitive viewpoint that sees visually perceived naturalness and abnormality as a realistic probability issue. Lastly, a customary viewpoint which is rooted in aesthetic tradition of cinema and animation. After that, the features of CGI which is used in the movie 'jungle book'(2016) were analyzed using the structured visual format. Consequently, this movie has hyper-realistic photographic iconicity on the base of realistic probability. Also, by following image-aesthetic convention which uses overstated and amplified narrative as a visual format, at the same time, the movie also has sufficient image-aesthetic convention in animation by personified animal character.

When visual and auditory information is presented simultaneously, we perceive visual information dominantly over auditory information. This effect is called the visual dominance effect. This study was to examine the influence of semantic congruence of visual and auditory information on the visual dominance effect. The semantic congruence of visual and auditory information was manipulated. The results showed that the visual dominance effect obtained in error rates was not modulated by semantic congruence, whereas the effect in RT was. It is suggested that this modulation of the influence of semantic congruence on the visual dominance effect would be due to the task type.

Objective : The purpose of study was to visual scanning program on the effect of visual memory in stroke patients. Method : A single subject experimental research with ABA design was employed in this study. The experiment composed of 15 sessions in total: 5 sessions for baseline, 7 session for visual scanning program, and 3 sessions for the second baseline. Each session for intervention took 30 minutes daily. MVPT, CNT(visual span test, visual learning test) were used for assessment visual perception, visual memory. Result : After visual scanning program, changing faster processing time MVPT 5.5 seconds to 4.5 seconds. Also all itme raw score changes of CNT visual span test, visual learning test. Conclusion : Visual scanning program in stroke patients give a positive impact on the visual memory. To improve stroke patients' perception visual scanning program utilizing visual perception research as well as training programs for a variety of looks forward to being developed.

The study investigated the users' functional requirement, degree of acceptance and preference of game broadcast real-time review .Secondly it comparatively analyzed the types and locations of game broadcast real-time review through eye tracking tech. The results show that users have high functional requirements and high acceptance for game broadcast real-time review but their preference has no significant correlation with the feature. Among the types of game broadcast real-time review the type with translucent text bubble took the highest visual attention. The above shows that the users' visual behavior has the tendency of special style. The visual attention analysis results of different types and locations of game broadcast real-time review in the study can play a guiding role in the interface design of real-time review feature in the future.

In this paper, we calculate the word frequency by date and region using news data related to COVID-19 distributed for about 8 months from December 2019 to July 2020, and visualized the correlation with the current state data of COVID-19 patients using the results. News data was collected from Big Kids, a news big data system operated by the Korea Press Promotion Foundation. The visualization system proposed in this paper shows the news frequency of the selected region compared to the overall region, the key keyword of the selected region, the region of the main keyword, and the date change of the selected region. Through this visualization, the main keywords and trends of COVID-19 confirmed and infected people can be identified for previous events.

This study analyzed the creative properties of public service advertisements and public content in outdoor advertising. The results of a case analysis focusing on outdoor advertisements for fundraising are as follows. First, government ministries were mainly found as advertisers. Second, most of the advertising messages were about policy promotion by the government and public institutions, with few public content or public interest messages. Third, in terms of expression, text took up more weight than visual elements, and illustrations were the main visual expression element. This proves that the public content of domestic outdoor advertisements mainly has a strong purpose of conveying direct information.
