  • We investigated how combining different types of images with written text affects the comprehension of health related information. The types of images were picture, photograph, and X-ray. 47 four year college students were recruited for the experiment. The independent variables in this study included information presentation format, vividness of image, and the degree of awareness for the disease. The dependent variables were recognition and recall for information. The results showed that the information with images in recognition and recall had higher score than information with written text only. In regard to the effect of different kinds of images on comprehension of health information, information with picture had higher score than the information with photograph and X-ray. The vividness of image were found to work as a negative factor on the recognition of information. Finally, the degree of awareness of disease also failed to have any significant effect on subjects' recall and recognition. This research has implications for the contents design of health related website.

  • 'Naturalness' is the important "ness" which is a key factor in image quality assessment. 'Naturalness' is a representive factor depending on the context of the image which arouses different emotions. The Image Quality Circle was split into two steps. The first step is predicting the visual perceptual attribute which are lightness, colourfulness, hue and contrast. The next step is SSE which is dependent to image contents. In this study the image contents are grouped in genres. The images were rendered using four different colour attributes which are lightness, contrast, colourfulness and hue. Using a scale, the score of image quality and SSE was asked to each participant for all rendered images. A seven-point category scale of increasing amount of "ness" is used as a quantitative adjectives sequence. The image quality model was built by combining the SSEs for each scene. The SSEs, where vividness is common, are considered as independent variables to predict the image quality score. Then the vividness model was built using colour attributes as variables to predict the vividness of each scene (genre). Vividness is an important factor of naturalness which the meaning is different for all scenes that links the naturalness and image quality. The vividness meaning was different for each scene (genre). Therefore, the colour attributes that express the vividness would depend on the image content.

  • Previous studies show that VR images can influence consumers' attitudes and behaviors by evoking imagination. In this study, we introduce a reality-based closed-loop 3D image (hereafter Virtualgraph). Then we try to see whether such image would increase evocativeness in a mobile commerce environment and whether higher telepresence of the visual image of a product can increase the purchase intention of that product. In order to find the above, we developed a model comprised of constructs containing telepresence, perceived value price, perceived food quality, and vividness of visual imagery questionnaire (VVIQ). We used Virtualgraph application to conduct an experiment, and then conducted an interview as well as a survey. As results of the experiment, survey and interview, we found the followings. First, users evoke imagination better with Virtualgraph than with still images. Second, increased evocativeness affects purchase intention if the perceived quality of fresh food product is satif actory. Third, increased evocativeness makes users value products higher and do even much higher when the perceived quality of fresh food product is good. From the interview, we could find that the experimental group had higher purchase intentions and perceived products as more expensive ones. Also, they perceived images of products clearer and more vivid than did the control group. We also discuss the strategic implications of using Virtualgraph in mobile shopping malls.

  • 본 연구에서는 실제 기증받은 시체를 이용하여 인체의 각 구조물을 실제 모습 그대로 3D 이미지화하는 과정에 대해 알아보았다. 인체의 구조물을 3D 로 이미지화하는 과정은 다음과 같다. 먼저 시체를 0.2mm 간격으로 절단하여 절단면의 사진을 찍은 후, 각 절단면의 사진에서 각각의 구조물을 구역화하여 색칠을 한 후, 구역화한 이미지에서 외곽선을 추출하여 벡터 이미지를 만든다. 이 외곽선을 1mm 간격으로 쌓아 올린 후 그 표면을 재구성하여 3D 이미지로 변환하는 과정으로 진행되었다. 3D 이미지의 제작은 가슴 부위에 한정하여 이루어졌다. 인체의 해부학적인 모형을 3D 이미지로 시각화함으로써 얻는 효과는 일반인을 대상으로 인체의 내부에 대한 시각적인 호기심을 충족시켜주고 의학 상식을 넓히는데 도움을 줄 수 있을 것 이다. 또한 의대생들을 비롯한 의학 전문가들에게는 생생한 해부학 강의용으로도 활용 가능하다. 향후 Haptic 시스템을 이용한 의료 실습 어플리케이션과 접목될 수도 있을것이고, fMRI 데이터를 비롯한 타 데이터와의 융합을 통해 시각화하여 서비스 할 수도 있다. 이처럼 인체의 3D 모형은 의료분야에서 광범위하게 활용될 수 있는 데이터로써 그 가치를 지닐 것이다.

  • In order to attain 'reality', technology, style and narrative have developed throughout the history of cinema. The projection of digital image necessitated a new perspective beyond the conventional relationship between film and reality. In the SF film, DISTRICT 9, strong realism elements are evident despite its genre. Advanced technologies enabled the digital images to vividly reproduce the realm of imagination. The encounter of the realistic approaches embedded in the style and narrative with the digital images emphasizes the social context of the cinematic background, as well as extending the potentialities of verisimilitude and perceptual realism. The amount of freedom in editing process derived from this film's documentary-like style opened a possibility for the effective delivery of the vast information-furthermore contributing to the realism of the film by encompassing the diversity that exists in the reality.

  • 증강현실(AR)이란, 현실의 이미지나 배경에 3차원 가상 이미지를 입혀 실시간으로 출력되는 컴퓨터 그래픽 기법이다. 본 논문에서는 AR 서비스를 이용한 여행 기록 애플리케이션을 제안한다. 현재 제공되는 서비스에서는 장소에 대해 제공하는 정보가 매우 한정적이다. 따라서 공유 커뮤니티를 형성할 수 있도록 하여 다양한 정보를 전달하고 직접적인 시각 자료를 제공받을 수 있는 애플리케이션이 필요하다고 생각하여 기획하게 되었다. ReactNative와 SpringBoot를 사용하며, MySQL을 이용하여 데이터를 저장한다. Google Map API를 활용하여 사용자가 기록하고자 하는 장소에 대한 위도와 경도 정보를 받을 수 있도록 하며, AR 기능은 Unity로 구현하였다. AR을 포함한 혼합 현실 서비스를 제공하여 사용자들이 본인의 경험에만 의존하는 것이 아닌 풍부한 몰입력과 현장감을 통해 보다 가시적이고 생생한 다이어리 기록을 만들 수 있다.

  • 웹툰은 카툰을 대신하여 웹에서 새로운 카툰으로 등장하였고, 웹의 특징을 가지고 웹상에서 길이에 대한 제한을 받지 않으면서 세로로 스크롤 되면서 콘텐츠를 구동하게 된다. 웹툰의 제작은 대부분이 2D의 이미지 형태가 대부분인데 비사실적 표현기법으로 2D와 3D 비디오로 표현 형식으로 나타내었다. 비사실적 표현으로 2D의 플래시 기법과 3D의 모션 기법을 적용함으로 화려함과 생생한 리얼리티을 얻을 수 있지만 단점으로는 제작기법과 콘텐츠 재생 시간에서 콘텐츠의 용량 확대와 플레이 해상도 및 재생 런 타임 응답 속도 고려가 되어야 한다.

  • The art of dynamic images has experienced three development stages, including experimental films, recording art, and new media image. By introducing all kinds of new materials, new media to the art, and the art of dynamic images has created more freedom for art creation. With the development of digital information technology, dynamic image works have put forward an increasingly high requirement of visual art. The combination of dynamic images and visual illusion can give rise to different forms and expression methods, thus endowing artworks with more vigor. This paper provides an overview by sorting out the lineage and development of dynamic images in the background, as well as understanding the application and performance of contrasted visual illusion. Based on the understanding of the characteristics of visual illusion, we discuss the new characteristics of applying the theory of visual illusion to new media dynamic images in relation to the technical approach of dynamic images. Through the analysis of specific works of Telematic Vision, we search for its reasonable combination and find the appropriate technical means of implementation. We discuss how to use digital multimedia technology and spatial optical illusion to make the design more novel and impactful, and consider how the combination of digital dynamic image technology and visual illusion should be interpreted and applied.

  • Hangul came to life as part of the East Asian culture of the Chinese ideograph. Korean letter-culture is starkly different from that of Western letter-culture. In the Orient, letters were sacred and incantory; they were objects of awe, which incorporated elements of the majestic, mysterious, and of ritual. Here we had cultural tradition that acknowledged the intrinsic value of the letters. And it was in this context that Hangul was born as a completely phonetic system of writing. However, the characteristics of Hangul are quite different from those of Chinese ideographs, which are designed to convey a certain meaning. Despite the fact that Hangul is phonetic, its roots lie most definitely in the image of Chinese ideographs. This is something that contrasts with the roots of the Latin alphabet, which have been lost in its long journey of evolution. As a phonetic writing system, a notable characteristic of Hangul is that it has this and the attributes of image. In other words, in that Hangul is a compound, it shares some of the same attributes as Chinese ideographs, but also in that it is a phonetic writing system it is dose to the Latin alphabet. Hangul is definitely a visual writing system that has its origins in the visual culture of Chinese characters as well as being functionally a highly developed phonetic writing system. In short, Hangul has both of these attributes in one writing system. These characteristics of Hangul, for us living in the era of the image, are parts that awaken us to the meaning of existence in our visual culture. Unique among the world's writing systems, the identity of Hangul typography will become none other than the essence of our visual culture.
