This study develops a user centered outdoor jacket capable of energy harvesting based on consumer needs. Jackets are designed for typical outdoor activities such as hiking, trekking, and climbing, integrated with an energy harvesting module that can generate electric power from arm swing in outdoor and daily life walking. Textile based energy generators developed by the previous research of Lee & Roh (2018) were used. A prototype was created based on the arm swing motion experiment for location options and energy harvesting system functions, the simulation by the design sketch, and evaluation of the wearing test by experts. In-depth interviews were later conducted for the prototype with 10 outdoor experts to derive the optimal location of an energy harvesting system in three ways, and the prototype was revised to 5 styles that reflected reviews by experts on function and appearance. Research indicated that the energy harvesting jacket design signifies a user-centered design based on expert interviews and usability evaluation as well as previous research on energy generation and storage device. The jacket is convenient because it combines an energy generator in an optimal position to maximize energy generation with a storage and charging device that can be inserted into various position options for accessibility.

지금까지의 UI(: User interface)는 GUI를 바탕으로 연구되어 있기 때문에 증강현실 환경에서 사용되는 UI를 정의하기에는 그 내용이 충분하지 않았다. 본 연구는 가상환경에서의 UI에 대한 연구로 증강현실한경에서 UI의 사용성 요소를 연구하였다. 이 연구에 사용된 평가 방법은 가장 대표적인 넬슨의 휴리스틱을 중심으로 연구되었다. 그러나 기존에 정리된 사용성 원칙들은 다소 보편적이고 일반적인 개념들이기 때문에 증강현실 UI 적용하기 위해서는 증강현실 환경에 맞는 항목을 세부화 시키는 노력이 필요했다. 사용성 평가의 기준을 정하기 위해 넬슨의 휴리스틱 평가방법을 중심으로 국내외 관련 연구를 조사하였으며, 조사된 사용성 요소 중 중복된 내용과 증강현실 환경에 적용하기 어려운 요소는 제거하여 증강현실에서 사용 가능한 25 사용성요소를 선별하였다. 선별된 사용성 요소는 본래 가지고 있는 요소개념에 증강현실 환경에 적합하도록 요소의 개념을 구체화 시켰다.

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.

This study aims to design user-oriented children's hospital by examining the user needs, especially the mothers of child inpatients and the nurses. The subjects participated in a questionnaire survey including the user's characteristics, awareness of patient's room, the preference on ward size, demands, satisfaction and hospital environment assessment. The survey was conducted of the mothers of child inpatients and the nurses in A children's hospital, and the data were analyzed by the SPSS WIN 18.0 Version software. A total of 115 copies of the questionnaire were finally analyzed. The results and conclusions are as follows. 1) The mothers' demand on family-centered space and private spaces were higher than the nurses. 2) The mothers preferred 1-bed-room to 4-bed-room due to safety and privacy. 3) The items of hospital environment assessment was categorized into four factors; 'Aesthetics', 'Accessibility', 'Comfort', and 'Lighting'. The most positive factor was 'Aesthetics', whereas 'Comfort' was the negative factor. 4) The mother's satisfaction was lower than the nurse's. The most influential factors on the satisfaction was 'Accessibility'. To improve the satisfaction of the mothers of child inpatients and the nurses, safety, privacy, accessibility should be considered.

Currently, various technological models and services are emerging because of the development of information and communication technology and the convergence of industries. The ICT car field is expanding because of technological convergence in the automobile industry. However, ICT convergence services are still being developed based solely on technology; characterization of users and their needs is lacking. Therefore, two types of ICT car services that apply human-centered design processes are developed in this study. These processes create services and models while considering the quality and functions of products based on users (instead of technology) when developing products or services. Usability evaluation was performed on the developed services; a human-centered design process was applied to the results to confirm that the derived services resulted in high satisfaction. In the future, these research results will provide useful applications when developing ICT car services and strategies.

Multimedia systems present information by various media, for example, video, sound, music, animation, movie, etc., in addition to the text which has long been used for conveying the information. But using several media may cause users' confusion and poorly designed user interface often aggravate the situation. Hypermedia systems allow the retrieval and representation of multimedia information using navigation and browsing mechanisms. Typically, there are two major navigation problems in a hypermedia compared to the ordinary user interface: disorientation and cognitive overload. In this study, the multimedia system was studied from the viewpoint of usability. Practical usability evaluation needs cost-effective, low-skill, and low- investment methods. The 'discount usability engineering' method, one of these methods, is based on the use of the following techniques: scenarios, simplified thinking aloud, and heuristic evaluation. The discount usability engineering method was applied to the usability evaluation of multimedia CD-ROM title.
