This study proposes and demonstrates the value of user - centered design methodology based on linguistic analysis. The results of the proposed user behavioural analysis framework suggested that the syntactic structure between the sentence structure and its components could be a logical basis for explaining the user's situation and behavior. Based on this, the definitions and classifications of user interactions and user contexts were conducted in a microscopically context. User behavior has also been established to identify pattern structures of purposeful nature and constitutes a user behavior sequence that prioritizes them. Next, the User Experience Analysis Framework was derived by defining the relationship between User Behavior and User Behavior and User Context and User Context. To verify the framework of the framework, a professional assessment was conducted to conduct a review of the user's experience and conduct a study of the framework of the framework and conduct of the framework of the framework of the framework and practical utility of the framework. Through this, it was possible to identify the value of the qualitative and quantitative framework of the framework and the future direction of development.

This study deals with the issue of actual HCI design embodiment through the investigation on how to interpret and use visual expression means in HCI design in a semantic way. The purpose of this study is to provide the method by which designers can make the user-centered guidelines in HCI design. As a part of the user\ulcornercentered design approaches, this study is based on the understanding of user group types which are divided by his/her extent of exposure to computer especially and is focussed on applying the level of each group's apprehension of visual expression means to the embodiment of HCI design. Major findings of this study are: First, it proposes the 'Visual Tokens Models' as a basic source for the understanding and the embodiment of visual expression means in HCI design; Second, it has examined the correlations between the characteristics of Visual Tokens and user group types that is, naive users, casual users, and expert users; Third, it proposes guidelines for the user-centered embodiment of HCI design in accordance with the correlations.

Future-oriented train design should be able to provide highly refined traffic culture and public transportation service by achieving 'higher value addition, sensitization, and humanization' and then securing safety, convenience, and amenity. Therefore, design of FRT, as a means of environment-friendly public transportation, should have new concepts achieving harmony between design and technology. Consequently, when designing interior of trains for public transportation, it should aim for user-centered strategies. This approach is essentially applied to vehicle design and inducement to new concepts by design aesthetics and their verification become requirements for train Interior design, which should be equipped with sensitivity and functional images. Accordingly, a study on the correlation between constituents in order to implement design is essential to design planning and realization of strategies.

Objective: The present study developed a user-centered 3D virtual liver surgery planning (VLSP) system called Dr. Liver to provide preoperative information for safe and rational surgery. Background: Preoperative 3D VLSP is needed for patients' safety in liver surgery. Existing systems either do not provide functions specialized for liver surgery planning or do not provide functions for cross-check of the accuracy of analysis results. Method: Use scenarios of Dr. Liver were developed through literature review, benchmarking, and interviews with surgeons. User interfaces of Dr. Liver with various user-friendly features (e.g., context-sensitive hotkey menu and 3D view navigation box) was designed. Novel image processing algorithms (e.g., hybrid semi-automatic algorithm for liver extraction and customized region growing algorithm for vessel extraction) were developed for accurate and efficient liver surgery planning. Usability problems of a preliminary version of Dr. Liver were identified by surgeons and system developers and then design changes were made to resolve the identified usability problems. Results: A usability testing showed that the revised version of Dr. Liver achieved a high level of satisfaction ($6.1{\pm}0.8$ out of 7) and an acceptable time efficiency ($26.7{\pm}0.9 min$) in liver surgery planning. Conclusion: Involvement of usability testing in system development process from the beginning is useful to identify potential usability problems to improve for shortening system development period and cost. Application: The development and evaluation process of Dr. Liver in this study can be referred in designing a user-centered system.

The phenomenal rate of growth of the design, implementation and use of interactive computer-based systems has been paralleled by an appreciation of the criticality of the human factor with regard to successful systems operation. As the pace of technological innovation quickens, and the design of user interfaces involves more complex interaction techniques, user frustration, confusion, degraded human performance, and an unwillingness on the part of users In perform interaction tasks were potential outcomes. Consequently, the important of user-centered interfaces design and use is increasing. Usability-based systems improve user acceptance and satisfaction with the systems

Ethnography, a major research method in Anthropology, has been recently applied in human-centered design research. Since ethnography has empirical, naturalistic, holistic and eclectic characteristics, it is needed a guideline to apply ethnography into design research in accordance with a characteristic of project. Design project in which ethnography is applied can be categorized by two criteria; degree of newness of project goal(existing user-potential user) and limitedness of worksite(site-oriented-work-oriented). Among work-site activities, technology in use, and user group culture, it should be decided which content to content to focus more than others and thus what kinds of research techniques to apply in the ethnographic research.Case study was to design an interior of a Korean express train. This project is site-oriented and has an existing-potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity flow, and participant observation was applied to obtain statistical data of synchronous activities. Case study shows a concrete process example of how to apply ethnography into design research.

Due to high cost of domestic production structure, steep growth of China's manufacturing business, and increase in oversea's production, building integrated system to support user-centered product design system based on cognitive and affective information is required to restore development of domestic manufacturing business. This paper put purpose on analysing requirements of end users, especially on information equipment business which works as a major industry in manufacturing businesses, and planning system design direction, prior to constructing user-centered product design support system based on cognitive and affective information. Research was conducted to identify current manufacturing process, application data on manufacturing, availability of cognitive and affective information data and its method of use, and necessity of user-centered product design support system based on cognitive and affective information, by carrying out in-depth interview with 6 related manufacturing companies. Need for user's character information was deducted from the interview, especially cognitive and affective information which is demanding for small to medium manufacturing business to research on its own.

The purpose of this paper is to present the direction of emotional lighting design of a new concept suitable for the user's living environment based on the experiment and the result of the recognition of the cognitive effect of the color of the lighting on the user's sensibility. As a research method, we collected meaningful results of color temperature and emotion of light through literature research and experimented with users in their twenties. Based on this, we presented the design direction of emotional lighting. As a result, we designed emotional lighting that can transform the shape of the four joints freely to realize the user's demand. We also derive the color temperature of light that can be optimized for the user's work and environment, Concentration, mood, and relaxation. The result of this paper is meaningful and worthy of suggesting emotional lighting design with user - oriented new perspective, deviating from previous method of planning lighting.
