To find out media's function on the various effects in communication, this paper reviews studies that utilize multimedia as a device for conveying information. We discuss multimedia as an integrated symbol system with advantages and also problems in representing information. The cognitive dissimilarity of media could be explained by various attributes of medium that are about physical characteristics and even cognitive actions. With advantages from integrated media and interactivity, multimedia has negative results such as cognitive overload and in that reason systematic approach is needed. This paper shows the factors on media selection and relationship to interface components. To select appropriate media to the needs and situation, it should be considered the user's ${\circled1}$background ${\circled2}$knowledge / frequency of use / expertise, contents ${\circled1}$task nature ${\circled2}$type of knowledge and media ${\circled1}$representation format ${\circled2}$interaction techniques. Varying the media factors and varying the expression factors offers concrete design features.

The purpose of this study is to investigate the interaction factors(learning motivation, concrete feedback, learner's control) and affordance factors (aesthetics, playfulness, stability) that influence flow in e - learning. This study collected 236 survey data from e-learning users. The data was analyzed the statistical relationships among the variables using the SPSS21 and AMOS21. The measurement model was reliable and valid, and the structual model was good. The result shows that interaction factors (concrete feedback, learner's control) and affordance factor (playfulness) influence on flow. Flow has a significant effect on satisfaction. Especially the effect of playfulness on flow is meaningful. Playfulness is one of the most important factors leading to the flow state of humans. The contribution of this study is to find the factors influencing flow in the interaction between learners and computer in e-learning. It can be used to provide an entertainment experience that can enhance the satisfaction of consumers in the Internet environment by finding the antecedents that affect the flow in computer - human interaction.

This study analyzes user behavior on YouTube Shorts within snack culture and proposes short-form video production strategies by identifying key value factors. Prior research identified seven characteristics (playfulness, time killing, information provision, social presence, interactivity, escapism, conciseness) and criteria based on the 5W1H principles. Surveys and interviews revealed that key user values are playfulness, time killing, conciseness, and interactivity. Users engage without specific purposes, watch 10-20 consecutive pieces selectively, and use it in comfortable environments. This research provides insights for understanding user behavior and short-form video production strategies.

본 논문은 픽토그램(Pictogram)의 시각전달 요소를 재해석하고 증강현실 환경에서의 효율적 전달 방법에 대하여 제안한다. 픽토그램은 국경을 넘어 남녀노소 모두가 인지할 수 있어야 함이 규칙이며 불특정 다수라는 사용자들을 위해 정확한 정보를 담고 있는 시각전달 매체로서 공정성, 객관성을 가지고 디자인 되어야 한다. 사용자에게 정보전달 인식을 높이기 위해 표준 픽토그램 과 문화 속에서 발견할 수 있는 행위들을 접목하여 애니메이션으로 제작하고, 이를 다양한 연구분야에서 응용되고 있는 증강현실 (Augmented Reality 또는 AR) 기술에 적용하여 표현하였다. 증강현실은 사용자-콘텐츠 정보전달 매체로서 현실 환경을 기반으로 하는 3 차원공간의 시각정보에 대한 사용자의 인식을 향상시킬 수 있는 방법으로 인간-컴퓨터 상호작용(Human-Computer Interaction)을 제공한다. 본 논문에서 제시된 픽토메이션은 기존 공공장소 어디서나 만날 수 있는 다양한 픽토그램을 패턴화하여 마커로 활용하고 사용자는 현재 널리 보급되고 있는 UMPC 혹은 PDA를 통하여 증강현실 환경에서 제작된 픽토메이션 콘텐츠를 경험해 볼 수 있다. 픽토메이션은 시각커뮤니케이션의 효과를 증가 시킬 수 있고, 정보습득의 주체인 사용자에게 콘텐츠의 종류를 예측할 수 있는 선택의 자유를 준다. 본 논문에서는 멀티미디어디자인 요소를 포함한 콘텐츠와의 실시간 상호작용을 통하여 유희적 요소의 접목을 시도하고 증강현실환경에서 Pictomation을 통하여 사용자들과의 효과적 커뮤니케이션을 위한 방법을 모색하고자 한다.

Tabletop games have been applied to improve the ability of social collaboration based on the characteristics that more than two people simultaneously interact on the tabletop. Especially, the tabletop games can be used as an educational tool for children with autism when it is implemented by considering educational and psychological models for children's behavioral characteristics. However, the previous collaborative games were designed for only disabled children so that it is hard to reflect cognitive and humanistic effects in inclusive education, where disabled children and non-disabled children interact in a same spatiotemporal environment. In this paper, therefore, we design a collaborative game on a multi-touch tabletop to enable spontaneous communication between disabled children and non-disabled children. Through user study, we evaluate the improvement in terms of the positive interaction and the degree of attention by comparing with a conventional collaborative game(e.g., a board game). We found that negative interaction including disabled children's abnormal behavior decreased and positive interaction such as body gestures and verbal communications increased. In addition, the tabletop game supported high immersiveness to all children by deriving equal level of attention time including individual and joint attention. We anticipate that the proposed game design can be utilized to develop collaborative contents for people with differences on sociality and cognitive ability.

Websites support various user activities in a wide range of contents domain and so they require different approach to extract principal design problems. In the point of media perspective on websites, this paper figures out the relationship between designer, user and website and discusses design factors of usability. It aims for the basic framework for interface design. In the media perspective website is an information entity mediating user and designer. Information entity is composed of various design factors relating to user, designer, website and others. It intends that user and information entity are accommodative to each other and have common conceptual model. To do so it is necessary for achieving usability objectives such as effectiveness, efficiency and satisfaction based on the understanding user goal, cognitive and affective characteristics. In the point of usability we examine design factors and features that are appropriate for users cognitive and affective function according to information entity model that constitutes contents, organization and representation level.

This paper mainly focuses on comparison analysis of the quality factors targeted at one shopping mall web site in Korea and China. There are a total of 14 hypothesis, and we use the SAS 9.2 statistical package tool. The survey to verify those hypothesis is filled out by 519 voluntary participants. The following describes the results that are found. The shopping mall web site of two countries shows a difference in terms of design, communication, community, commercialization, security, customer satisfaction, repurchase intention, contents, e-commerce, customer loyalty, interaction, technology, reliability, and size. Therefore, we suggest how to implement more effective shopping mall websites based on those 14 factors.

In order to improve players' satisfaction with the game NPC (Non Plyer Character), a Structural Equation Modeling (SEM) was made, and NPC design elements were analyzed. First, extract the design elements (entertainment, artistry, interaction, and presence) that affect player satisfaction. And it is assumed that these factors will affect the satisfaction of players, and empirical research is carried out through quantitative research ideas. The results of the analysis of the questionnaire survey data show that four elements have a meaningful impact on player satisfaction, and artistry has the greatest impact on player satisfaction. Finally, according to the analysis results, a proposal for NPC design is proposed. It is expected that this research will provide a reference frame for the design direction of NPC in the future.

다양한 게임의 분야 중 온라인게임의 가장 큰 특징은 게임 속 캐릭터가 게이머 지시에 따라 역할을 수행하며 이를 통해 캐릭터가 성장하는 상호작용성을 갖는 것이다 온라인 게임에서의 캐릭터는 게이머 자신을 표현하는 대상이 되며 동시에, 현실의 자아와 게임의 세계관이 결합해서 나오는 하나의 인격체이기도 하다. 캐릭터 선정은 게이머가 게임을 시작하기 위해 진행하는 최초의 행위이기 때문에 게이머들은 각자 판단하는 기준을 사용하여 캐릭터를 선정하게 된다. 따라서 게이머의 캐릭터 선정 기준을 파악하는 것은 게임 캐릭터를 기획/디자인하는 과정에서 필수적인 사항이라고 말할 수 있다. 본 연구에서는 게임캐릭터를 선정하는 과정에서 게이머의 결정에 영향을 미치는 요인을 분석하기 위해, WoW 여성 캐릭터의 성격과 호감도를 중심으로 가설을 설정하고 연구를 진행하였다. 캐릭터의 선정 과정과 호감도의 상관관계를 알아보기 위하여 피설문자의 캐릭터 선정 순위와 피설문자가 평가한 각각의 캐릭터의 호감도와 성격의 5요인을 분석하여 캐릭터의 선정 결과와 호강도의 관계를 도출하였다. 이를 통해 가설을 검증하고 게임 캐릭터의 기획 및 디자인 과정에서의 캐릭터 구성 방향을 제안한다.
