본 연구에서는 일상 생활 속에서의 사람들의 행태(behavior)를 Digital 환경에 반영하여, 보다 사용자에게 친숙한 형태의 사용자 경험을 제공하고자 한다. 그리고 사용자에게 감성적인 요소를 제공함으로써 컴퓨터 기기와의 Interaction 과정에서의 사용자 만족도를 높이고자 하였다. 우리는 이 연구를 통해서 User Preference 를 고려하여 사용자 의지에 따라 UI 의 변경이 가능하도록 하는 User Interface 의 설계를 제안한다. 또한 살아있는 객체와 interaction 하는 것 같은 느낌을 제공하여 사용자의 감성적 만족도를 높이고자 했으며 이 과정에서 Fluid interaction 의 개념이 적용되었다. Digital 환경의 한정된 공간을 효율적으로 사용할 수 있도록 하기 위해서 Zoomable UI 의 개념을 적용하여 사용자에게 효과적인 정보 전달을 하고자 하였다. 이러한 연구의 결과로서 Zoom in/out 이 가능한 새로운 개념의 Memo Application 을 설계, 구현하였다.

The purpose of this research is to analyze priority of the elderly user interface (UI) evaluation criteria based on user's lifestyle. Since the elderly population will occupy over 20% of the all Korean population in the near future, we need to know older users' needs and information because elderly users will be main customers in the super-aged society. This paper investigated the definition of elderly users and characteristics demographically, socio-economically, and physically/cognitively. A total of 238 questionnaires from older users were analyzed based on a segmentation table for the elderly developed by the previous study. According to factor analysis and cluster analysis, 6 types of lifestyle and 4 groups of the elderly users were classified, respectively. The priority of UI evaluation criteria for large electronic home appliances and mobile products was analyzed by analyses of variance (ANOVAs). The results indicated that the priority of (physical, emotional, and cognitive) UI criteria was significantly different among elderly users' lifestyles for both home appliances and mobile products. Consequently, the results of this study may help the company develop some competitive silver products and give higher satisfaction to the elderly users by suggesting different priority of UI evaluation criteria according to the target elderly group. The results may also contribute to revitalize national economy by significantly increasing senior market shares.

In the field of user interface design for interactive product, it is becoming more important than ever to understand emotional quality and its characteristics. By a series of experiments on emotional quality of user interface, this paper aimed to develope a systematic approach to investigating emotional quality. First, a emotional quality framework that consists of 6 dimensions (Usefulness, Easy of Use, Aesthetics, Stimulation, Identification, and Harmony) and 18 elements was developed through two experiments that users and UI expert participated in. Second, by conducting a user survey based on the emotional quality framework, it was illustrated how various emotional qualities of interactive product can be evaluated and what effects they have on overall satisfaction of the product. Finally, this paper analyzed the relative importance of emotional quality dimensions and the contextual factors that change emotional quality, and provided basic knowledge related to the construction of emotional quality for the succeeding studies.

This study aims to investigate the specific functions of the five spirits based on the characteristics of five phases. In Korean medicine, the mind is classified into five spirits and seven emotions. The spirits (hon, sin, ui, baek, ji) are a way of analyzing of people's mental structures, and they are affected by each other, influencing life activities both directly and indirectly. They are also related to the five viscera and come into their own functions through the characteristics of the five phases that are assigned to the viscera. Sin is the main agent of mental activity that is normal, correct, and perfect, and it directs the other four. Hon is activity that is exposed to the outside from mental and physical aspects such as planning, creative thinking, creating, judgment, speech, and emotional expression. Baek is internal activity, such as obtaining information, learning, seeing, hearing, smell, taste, and touch. Ui is meant to decide between new and already saved information based on comparative analysis. Ji is the activity of making the final decision and saving it in ui. Based on the above, we suppose that the five spirits' functions match the characteristics of the five phases.

In the digital era, Korean universities are using real-time remote lecture platforms as a tool for learning. However, it is confusing due to low usage experience problems, and usability studies are needed. The purpose of this study is to measure, analyze, and propose gaze tracking and learning experiences according to the UI design layout of ZOOM. A total of 30 subjects were selected to conduct eye tracking and survey when learning. The experiment showed that grid layouts have a higher emotional realism and learning satisfaction than other layouts. Furthermore, it turns out that participants focused the most attention on grid layouts. Therefore, for high learning experience, grid layouts and layouts that visually highlight participants and induce communication are needed.

The final goal of this research is development of graphic design evaluation methodology in elevation of a usability at the mobile internet services and of measurement model which can forecast user needs in interface design, and systemize evaluation basis. For this, we systemize core contents of GUI design evaluation methodology and embodied UI design support system that supports prototype layout and evaluation process directly. The sight language that can inform flow of controled information by the quick and implicated method so that user may complete task in a short time without overload of recognition in limited display environment of Small Screen device it must improve objectivity in the reflection of UI design with image. Thus evaluation methodology that can evaluate usability of mobile internet systematically is important and specially, graphic design evaluation model which can forecast user's design need and trend is meaningful because of special quality that can reflect sensitive aspect of user in interface design. Mobile internet GUI was done by the result of this design evaluation, and I hope this result can be utilized for the GUI development of Ubiquitous environment for the future research.

The next generation Web 2.0 users are requiring a screen that satisfies visual and emotional factors regarding UI and the possibility of constant recognition about various information. To actively deal with these kinds of user demands, dual cooperation between the developer and designer is becoming more urgently needed. For this, Microsoft released Silverlight, a tool for when making a web presentation that enables persons to create a visually stunning webpage using diverse platforms and function. We applied clarity and animation to existing windows concepts, using Silverlight with which designers and developers can work together and is accessable to many development tools, and provided 3D effects to implement a Warehouse Management System.

미디어기기들이 디지털화 된 이후, GUI는 디지털기기의 활용도를 높여주는 매개체역할을 해왔다. 최근 출시되는 기기들의 그래픽 사양이 높아지면서, GUI는 어플리케이션의 접근성을 높여주는 소극적인 요소에서 사용자에게 다양하고 새로운 감성과 가치를 제공하는 보다 적극적인 요소로서 그 역할이 확대되고 있다. 본 논문에서는 사용자의 감성 만족도를 향상시키기 위해 시각적 주목성이 높은 Motion GUI를 도입하였다. Motion GUI의 시각 구성 요소들을 분류하고 각 요소에 따른 감성 정보를 도출한다. 또한 최소한의 그래픽으로 구성되어 있었던 기존 미디어 플레이어 화면에, 도출된 연구 결과를 도입하여 디자인한 Motion GUI를 적용하고 그 사용성과 사용자의 감성 만족도에 대한 결과를 기술한다.

In this study, we attempted to provide a distinctive cognitive, emotional 'Auditory User Interface (AUI) Design Guideline' according to home appliance groups and their functions. It is an effort to apply a new design method to practical affairs to overcome the limit of GUI centered appliance design and reflect user multimodal properties by presenting a guideline possible to generate auditory signals intuitively associable with the operational functions. The reason why this study is required is because of frequent instances given rise to annoyance as not systematic application of AUI, but arbitrary mapping. This study tried to provide a useful guideline of AUI in home appliances by extracting the relations with cognitive, emotional properties of a certain device or function induced by several properties of auditory signal and showing the empirical data on the basic mechanism of such relations.
