The new innovation model that deals with agenda as sustainability, quality of life, societal challenges is emerging as NIS(National Innovation System) is needed to transit to post catch-up and creativity. To achieve this objective, there is a growing need for enhancing usage of ICT, end-user's needs, prolification of R&D results and social impact. Living Lab is the new innovation model that end-user's participation, co-work/network within actors and usage of user's experience and This study deal with Living Lab related R&D of ICT-based service from co-work with end-users. Example cases are Turku Archipelago Living Lab in Finland, and Living Lab projects in EU, EIT ICT Labs and ELLIOT. And the focus of case analysis is that reflection of user's needs and experience, and aspect of ICT usage.

This study is a case analysis for user interface(UI) design of spectrophotometer which is widely used in the field of chemistry, biology and environment, based on user experience(UX). Generally, experimental equipment developments are centered on functionality and technology, and the interface for interaction between the user and the machine is developed only by the engineers who do not have much consideration for the users. From this background, this study tried to find out how UX could melt into UI so that a kind of spectrophotometers can be designed to help the work process of researchers in the real context by examining and analyzing the real users' experiences and also considering the developer's perspective. As a result, it was possible to improve UI and was found that redefinition of the goal of UI, time-efficiency, security, and sufficient information delivery are essential to the design of user interface for spectrophotometers.

In recent years, the service design in the medical sector evolves through practical service research and development that can visualize both intangible and intangible service elements in an integrative way and derive innovative solutions to help customers feel the service more important value. With the improvement of personal income, interest in medical welfare and well-being is increasing day by day, and the focus of the medical sector shifts from the concept of treatment of diseases and illness to preventive medicine. In response to this trend, research and development of home health care system, which greatly reduces the time and space constraint of health checkup and health care by combining ubiquitous concept with medical welfare, are being actively conducted, and the needs for improving products and medical environment based on user-centered medical service and user needs in accordance with the Health Care 3.0 Era, it becomes necessary to develop on-site medical diagnostic products that reflect user-centered needs and needs. This study is intended to research and develop a product that sufficiently reflects the needs of users by applying suitable materials and shape for on-site diagnostic product in researching and developing Wireless X-ray Detector.

낯선 환경에서 이동하며 여행하는 여행자들은 문화와 언어 등의 차이로 인해 어려움에 부딪히며 다양한 문제를 갖는다. 그로 인해 만족스러운 여행을 달성하지 못하거나, 안 좋은 추억들을 가지게 된다. 이러한 상황에 부딪힐 때마다 여행자들은 문제를 해결하기 위한 정보를 매 순간마다 찾아 사용하게 된다. 따라서, 만족하는 여행을 달성하기 위하여 자신의 상황에 가장 적절한 정보에 대한 니즈가 증대 되었다. 본 연구는 '미래의 유비쿼터스 컴퓨팅 시대의 여행자가 만족스러운 여행을 하기 위하여 정보 서비스는 어떻게 제공되어야 하는가?' 라는 물음으로부터 시작하였고, 이를 위하여 사용자의 상황에 따라 가장 적절한 서비스를 하는 컨텍스트 인식 서비스가 낯선 상황을 매번 접하게 되는 여행자들에게 유용한 방법으로 제시될 수 있을 것이라는 전제하에 진행되었다. 본 연구에서는 여행자가 처한 상황에서 가장 필요로 하는 최적의 정보를 휴대전화 인터페이스를 통해 얻음으로써, 만족스러운 여행을 할 수 있도록 컨텍스트 인식 서비스를 디자인하는 방법을 제안하였다. 연구의 내용으로는 첫 번째로, 여행자의 상황을 사용자의 목적을 이루기 위한 행위의 단계의 시점으로 보았다. 두 번째로, 여행자들은 목적의 행위단계마다 다른 정보를 사용하며, 원하는 정보의 우선순위는 발생하는 컨텍스트와 관련이 있다는 사용자 조사의 결과 도출하였다. 세 번째로, 이를 바탕으로 여행자가 가지는 목적 중 '식사하기'를 중심으로 각 상황마다 여행자가 필요로 하는 정보를 휴대전화를 통해 제공하는 컨텍스트 인식 서비스의 방법을 제안하고, 마지막으로, 이를 사례에 적용하여 서비스의 컨셉을 구체화하였다.

디자인의 여러 프로세스중 중요 행위는 사용자가 바라는 점을 파악하여, 제안하는 행위 중심으로 이루어진다. 사용자의 니즈를 파악하는데 있어, 사용성 평가를 활용하면, 논리적이고, 구체적인 불편요소를 파악하는데 도움을 받을 수 있다. 또한, 디자인 개선안의 효용성을 파악하는데도 디자이너에게 유용한 디자인 개발 프로세스로 자리 잡았다. 사용성 평가를 통해 사용자의 불편요소를 파악하는 방법으로는 크게 두가지 방법이 있는데, 하나는 데스크 탑 컴퓨터를 활용한 시뮬레이션 기법을 들수 있고 다른 하나는 모바일 폰을 활용하는 모습을 직접 촬영하여, 분석하는 방법을 들 수 있다. 데스크 탑 컴퓨터를 활용한 시뮬레이션 기법은 화면의 해상도와 인터렉션 방법이 상이하고, 직접 촬영 방법의 경우, 피 시험자가 카메라를 의식하거나, 분석상에 연구자의 바이어스가 개입할 여지가 많아 각각의 단점이 있다. 본 연구에서는 디자이너가 해결안을 프로토타이핑 하는 방법으로 모바일 폰의 프로세서를 활용한 로그를 남기는 방법으로 사용성 평가를 진행할 수 있는 도구를 만들고 이를 통한 사용성 평가 기법의 방안을 제안하였다. Mobile phone 의 Software User Interface 의 개선안을 검증할 수 있는 툴로 제작된 Interactive Mobile Phone Logger 라는 프로그램을Visual Basic 과 JAVA를 이용하여 개발하였다. 이를 활용하면, 디자이너의 해결안을 자동으로 JAVA Class 파일의 패키지로 생성해주고, 서버를 이용하여 패키지를 전송, JAVA를 지원하는 모바일 폰이면 어떠한 모델이든 실험에 참가할 수 있도록 제작 되어있다. 또한, 실험의 결과 데이터는 종료시 자동으로 실험자의 서버를 통해 분석될 수있도록 제작되었다.

Due to the development of digital technology, users can record their daily lives without being restricted by time and space. The trend is growing rapidly, but lifelogging cases are still insufficient. Google's Timeline and domestic application 'Daily' were analyzed through in-depth interviews. Based on the Creating Pleasurable Interface Model, the factors influencing user satisfaction were identified by the Reckard 7-point scale based on the Honeycomb model. The results of the in-depth interviews and the 7-point scale were similar, and we could see what and why users preferred the recording application. This study is meaningful to evaluate the user experience for recording application and analyzing the needs of users obtained through in-depth interviews to assess the usability that provide a service record and recall.

The survey was conducted on the Bungae Jangter and Danggeun Market, which provide mobile used market services. The goal is to investigate factors that affect the user experience of used market platforms and to compare usability. Based on Peter Morville's Honeycomb Model, a survey and In-depth interviews were conducted to users with experience in secondhand transactions. And we qualitatively analyze the factors that affect the user experience. As a result, there were differences in usability depending on the age of the user. (reliability, how to find things, purpose of using used trading services, etc.) This study focused on actual user experience, so it will help you find a way to develop to user-centered secondhand marketplace services.

This study applied the User-Centered Design(UCD) to develop effective VR safety training content for specific users. The UCD-based design was tailored to the VR, facilitating efficient design activities. The UCD process comprises key activities: deriving design concepts from user needs, designing with VR features, developing prototypes, conducting comprehensive evaluations with experts and users, and completing the finals. Unlike traditional UCD, this flexible approach allows iterative cycles, enhancing the quality and user satisfaction of VR safety training contents.

TikTok, as a leading short video platform, has attracted many users, and the resulting attention generates immense business value as a platform to diffuse knowledge. As a qualitative and explorative approach, this study reviews the knowledge payment industry and discusses the influential factors of users' payment decisions regarding knowledge products on TikTok. By conducting in-depth interviews with ten participants and observing 95 knowledge providers' videos, we find that TikTok has significant business potential in the knowledge payment industry. By using the ATLAS. ti software to code the data collected from these interviews, this study finds that demander characteristics (personal needs), product characteristics (product quality), provider characteristics (the key opinion leader effect), and platform characteristics (platform management) are the four core categories that influence users' payment decisions regarding knowledge products on TikTok. A theoretical model consisting of the ten variables of emotional needs, professional needs, quality, price, helpfulness, value, charisma, user trust, service guarantee, and scarcity is proposed based on the grounded theory. The theoretical and practical implications of the study findings are also discussed.
