Black/white comic rendering is one of the researches in the field of non-photorealistic rendering(NPR). Black/white comics have been produced manually as yet. But these previous systems require lots of time and manual work. So we propose the COmics Rendering system on VIdeo Stream (CORVIS) which transforms video streams into black/white comic cuts. Stylized font, one of comic representations, can be used to express onomatopoeic words and mimetic dialogue exaggeratively. But current comic generation systems do not provide enough effects of stylized font. This paper proposes a model for stylized fonts to express various effects. Effects of stylized fonts we proposed include geometric deformations. Thus we could represent stylized fonts on the still cut of movies and the background texture on a cuts of plain black/white comics. The final quality of our system produced is good enough to compare with manual black/white comics.

지리정보를 정보시스템에서 사용하기 위해서는 복잡한 실세계의 형상을 단순화, 일반화하여 전산적으로 처리할 수 있는 정보구조로 변환해야 한다. 기존의 2차원 GIS에서는 실세계의 형상을 점, 선, 면 등의 2차원적인 형상으로 수치 정보화 하여 GIS 기능을 수행하고 있다. 하지만 지구상에 존재하는 지리적인 요소들은 3차원적인 공간정보로 구성되므로 이를 2차원으로 추상화시키면 많은 정보의 손실이 일어나게 되며, 기존의 2차원 GIS는 근본적인 한계가 존재하게 된다. 따라서, 실세계의 3차원적인 지리요소는 컴퓨터 상에서도 3차원으로 처리하는 것이 지리요소가 원래 지니고 있는 정보의 손실을 최소화 할 수 있으며, 실세계의 자연물 및 인공 시설물에 대한 3차원적인 표현과 분석을 위해서는 궁극적인 형태의 3차원 GIS가 필요한 실정이다. 이에 본 연구에서는 점, 선, 면 등의 2차원적인 형상을 3차원 공간 데이터로 수치 정보화 하기 위한 수단으로 VRML(Virtual Reality Modeling Language)을 이용하여 Virtual GIS 적용을 위한 3차원 가상세계를 생성함으로서 각종 의사결정을 보다 효율적이고 시각적으로 행할 수 있는 공간데이터를 작성하고자 하였다.

The expansion of the performing arts market to include new genres of art that combine art and cutting-edge media technology has surpassed the limitations of traditional theatre art elements such as stage, costumes, lighting, sound, and props, allowing free expression of space-time and visual art. It is growing into a wide area with unlimited potential in the performing arts sector. In response to these changes and the demands of the time, there is an increasing demand for multi-talents who can plan and produce arts and technology-converged contents that will contribute to the development of the performing arts industry. As a result, university departments related to theatre art across the country feel that it is urgent to develop curricula that will enhance students' competency by incorporating the latest media technologies such as virtual reality, holography, and interactive motion sensors into the existing performance art visualization process. In this study, the author will examine the process of developing courses in technology-incorporated theatre art (design) through case studies of media technology-converged performances from the past 10 years. Based on the traditional concept of theatre art, the attempt to fuse stage art with media technology will be a cornerstone of attempts to foster a group of talented artists who transcend the limits of creative visual expression and creative value.

This paper analyzes the artistic practical use of social network visualization through the aesthetic information interpretation. The first social network visualization has emerged as 'Sociogram' in the form of social network analysis(SNA). Since social network has complex, the analyzing technology of social network has emerged. Early social network visualization has a practical purpose to measure the social structure, but current social network visualization divided into various forms from artistic expressions through information. This paper divide into two categories based on the artistic application of social network visualization. First, this research focuses on the static graph based on analog. Second, this research analyze the category of interacted visualization to generate a real-time digital image. This paper presents the fusion of paradigm between engineering and art through this way.

In the virtual space with the interactive 3D contents, the degree of mental satisfaction is determined by how fully it reflect the real world. There are a few factors for getting the high completeness of virtual space. The first is the modeling technique with high-polygons and high-resolution textures which can heighten an visual effect. The second is the functionality. It is about how realistic represents dynamic actions between the virtual space and the user or the system. Although the studies on the techniques for animating and controlling the virtual characters have been continued, there are problems such that the long production time, the high cost, and the animation without expected behaviors. This paper suggest a method of behavior control of animation by designing the optimized skeleton which produces the movement of character and applying the procedural technique using physical law and mathematical analysis. The proposed method is free from the constraint on one-to-one correspondence rules, and reduce the production time by controlling the simple parameters, and to increase the degree of visual satisfaction.

HTML is a format for rendering Web documents visually and uses tables to present a relational information. Since HTML has limits in terms of information processing and management by a computer, it is important to transform HTML tables into XML documents, which is able to represent logical structure information. As a prerequisite for extracting information from the Web, this paper presents an efficient method for extracting logical structures from HTML tables and transforming them into XML documents. The proposed method consists of two phases: Area segmentation and structure analysis. The area segmentation step removes noisy areas and extracts attribute and value areas through visual and semantic coherency checkup. The hierarchical structure between attribute and value areas are analyzed and transformed into XML representations using a proposed table model. Experimental results with 1,180 HTML tables show that the proposed method performs better than the conventional method, resulting in an average precision of 86.7%.

We cannot express emotions correctly with only speech because it is hard to estimate the kind, size, amount of emotions. Hamlet who is a protagonist in 'Hamlet' of Shakespeare has emotions which cannot be expressed within only speech because he is in various dramatic situations. So we supposed an artificial emotion, instead of expressing emotion with speech, expressing and visualizing current emotions with color and location. And we visualized emotions of characters in 'Hamlet' with the artificial emotion. We designed the artificial emotion to four steps considering peculiarities of emotion. First, the artificial emotion analyzes inputted emotional stimulus as relationship between causes and effects and analyzes its kinds and amounts. Second, we suppose Emotion Graph Unit to express generating, maintaining, decaying of analyzed one emotional stimuli which is outputted by first step, according to characteristic. Third, using Emotion Graph Unit, we suppose Emotion Graph that expresses continual same emotional stimulus. And we make Emotion Graph at each emotions, managing generation and decay of emotion individually. Last, we suppose Emotion Field can express current combined value of Emotion Graph according to co-relation of various emotions, and visualize current emotion by a color and a location in Emotion Field. We adjusted the artificial emotion to the play 'Hamlet' to test and visualize changes of emotion of Hamlet and his mother, Gertrude.

웨어러블 컴퓨팅의 지속적인 발전과 함께, 이들이 지원하는 기능은 점점 다양화되고 전문화되었다. 하지만 기기의 종류와 기능이 늘어나면서 각 기기의 상태를 확인하는 작업 자체가 복잡하고 불필요한 시간을 소요하기도 한다. 또한 이를 시각 디스플레이에만 의존하면, 디스플레이 크기의 한계와 더불어 시각적인 과부하가 발생할 수 있다. 본 연구에서는 이러한 문제를 극복하기 위해 웨어러블 각 기기의 상태정보 피드백으로서 소리를 이용하였다. 실험의 순서는 먼저 시각정보에 더하여 청각정보를 추가적으로 제시하는 방식의 유용성을 검증한 다음, 기기 특정적인 청각 아이콘(Auditory Icon)의 효과를 확인하였다. 청각정보의 유용성을 확인하는 단계에서는 참가자에게 특정 기기의 위치와 그 상태에 관한 정보를 시각 디스플레이를 통해 제시하면서, 조건에 따라 다양한 형태의 청각 디스플레이를 제시하고 기기 및 상태정보 확인에 소요되는 시간을 측정하였다. 시각디스플레이의 방식은 다양하지만, 본 연구에서는 사람의 몸을 나타내는 그림 위에 기기가 장착된 위치를 붉은 점으로 표시하고, 그 상태를 텍스트로 표시하는 방식(실험 1)과 텍스트를 통해 기기의 종류와 상태를 알려주는 방식(실험 2)을 적용하였다. 기기 확인에 소요되는 반응시간을 기록한 실험결과는 시각디스플레이를 통해서만 제시하는 조건보다 시각디스플레이와 청각디스플레이를 동시에 제시하는 조건에서 나은 수행을 보여주며, 정보의 내용이 일정 범위 내에서 구체적으로 제시될 수록 수행이 증가하는 경향을 보여주고 있다. 이어지는 기기 특정적인 청각 아이콘의 효과를 확인하는 단계에서는, 소리의 높낮이를 통해 기기의 위치를 표현하는 대신, 소리만 듣고 기기가 무엇인가를 알려줄 수 있도록, 참가자 평정을 통해 기기 특정적인 청각 아이콘을 선정하고, 이를 상태정보 디스플레이에 추가하였다. 기기의 수와 제시조건은 앞선 실험과 동일하였으며, 역시 기기 및 상태정보 확인에 소요되는 반응시간을 체크하였다. 실험결과는 이전의 실험과 비슷하게 시각과 청각 디스플레이의 중복제시 조건에서 높은 수행을 보였으며, 청각 아이콘의 사용으로 인한 수행의 증가도 확인할 수 있었다. 실험 2에서는 추가적으로 청각 디스플레이의 내용에 대한 주관적인 평정을 실시 하였는데, 기기 특정적인 청각 아이콘은 참가자에게 편의성, 효용성, 적합성, 확신도에서도 높은 점수를 얻었다. 이러한 결과는 청각 피드백을 이용한 정보의 디스플레이는 착용자의 시선을 자유롭게 함으로써 일상생활의 수행을 높이고, 웨어러블 컴퓨터 디스플레이 크기의 제약을 해결하는 방법이 될 수 있는 동시에 주관적인 사용성 측면에서 발전가능성이 있음을 보여준다.

Unlike face-to-face communication, text-based communication by digital media has limitations that non-verbal elements are eliminated and social presence decrease. To overcome this problem, people try to find solutions which visualize emotion and situation by using emoticons, icons, computer language and so on. As most SMS users experience the failure of using emotions on the mobile phone, they need to make up for this point. In this study, we conducted research on the recent mobile fonts situations and surveyed users' perception on SMS fonts as to suggest solutions of expressing and visualizing emotions on the mobile phone, a representative media of personal communication. As a solution of reducing the failure, we conducted a survey on users' perception about fonts and the capability of the expressing emotions by fonts. The survey found that mobile fonts can be used as a method to express human emotion. As a finding, the shape of the font can be used as a method to visualize the emotion through text messaging. In future studies, such a method can be applied to variety of different personal media with the communication method based on text. Those studies can propose different usage for fonts in communication.
