In order to make the IoT ecosystem more usable and friendly to general users, the interaction between the users and platforms/devices and its UX must be improved. In this study, a web-based rule engine system to help users intuitively interact with the various devices and services in IoE (Internet of Everything) platform is proposed. The proposed system consists of web interfaces and UI components for creating and managing rule-based scenarios using sensors, actuators, and external services in an intuitive way. Also, a rule management module for automatically translating the rules from the web interface into Nools rule engine compatible ones is proposed. Finally, we show the usability and feasibility of the proposed system by demonstration of rule-based use cases of IoT devices and external services.

This thesis was developed so that users can access tourism services more easily by utilizing Unity based on the metaverse. The core function and environment of the program were created using Unity, a game production tool, to create a virtual space. In the virtual space, it is implemented so that the tourist service can be used from various angles and positions through NPCs to which control and camera viewpoints are applied. This project is a content that allows you to visit tourist attractions in a virtual world without going to the site by using virtual reality technology. The background and goal of the project is to make it into a game form using a UI frame and fuse it into a simple game form to add fun elements to enable virtual reality tourist experience applying game for tourist attraction publicity.

Recently, the role of the kitchen has evolved from the space for previous survival to the space that shows the present life and culture. Along with these changes, the use of IoT technology is spreading. As a result, the development and diffusion of new smart devices in the kitchen is being achieved. The user experience for using these smart devices is also becoming important. For a natural interaction between a user and a computer, better interactions can be expected based on context awareness. This paper examines the Natural User Interface (NUI) that does not touch the device based on the user interface (UI) of the smart device used in the kitchen. In this method, we use the image processing technology to recognize the user's hand gesture using the camera attached to the device and apply the recognized hand shape to the interface. The gestures used in this study are proposed to gesture according to the user's context and situation, and 5 kinds of gestures are classified and used in the interface.

This study intends to look into the perception gap among Korean and Chinese consumers regarding the product attitudes toward smart phones and repurchase intention as well as the user experience. First, this study showed that there are gaps among Korean and Chinese consumers, regarding smart phones, toward their experiences of usage satisfaction, usefulness, design satisfaction, and evaluation from other people and that Chinese consumers have higher awareness of every experience element concerning UI than Korean consumers. Second, concerning the difference in the product attitudes toward smart phones, it turns out that Chinese consumers also have higher awareness of it than Korean consumers. Third, regarding the difference in repurchase intention for smart phones among Korean and Chinese consumers, this study shows that Chinese consumers are likely to have more intention than Korean consumers. because their average value is higher than Korean consumers' even though the difference are not statistically significant. This study is expected to have academic meaning(significance) for providing basic materials of comparative study between two countries regarding the user experience about smart phone as well as some useful implications for the competitive power improvement of Korean smart phone related companies in China.

This research investigates how digital design agencies and client companies incorporate design thinking-a human-centered approach to solving difficult problems-into their website development processes. Based on a literature review on the design-thinking-driven web development process, multiple case studies of award-winning website projects were performed by in-depth interviews with key practitioners. Through analyses of these cases, their user-centered approaches for website innovation were identified according to the following four phases: web planning (discovery and defining phases) and web design and development (development and delivery phases). Moreover, distinct approaches of design thinking practices were identified according to two website types: a brand promotion website with a killer brand storytelling approach; and a service channel website with a strategic UI/UX-driven approach. Next, the key success drivers of these website projects were suggested in light of the typical themes of design thinking (i.e., human centeredness, research based, context awareness, and collaboration). Some practical limitations were also found in adopting the design-thinking-driven web development process, such as limited research methods and tools, and insufficient prototyping and experimentation. Along with these limitations, it was also discovered that current digital design agencies still face the following challenges in adopting the design-thinking-driven web development process: building a long-term, playful partnership with clients; leveraging decision-makers' design thinking awareness; and coping with limited resources (design thinking practitioners, budgets, and schedules).

Purposes: The aim of this study is to evaluate whether the contents of hospital reservation and reception applications(apps) are qualitatively useful in meeting the needs of medical consumers and improving hospital accessibility and convenience. Methodology: (1) identify consumer needs through social data web mining, (2) describe the status of key contents of mobile apps to improve accessibility and convenience of care, and (3) verify the quality of apps through validated tools Finding: The contents of 'mobile reservation function' and 'waiting time information provision' that can contribute to reduction of delay time of care and efficiency of desk work were supported, but the level of utilization was insufficient. The quality level of the app, including the level of consumers' needs, has shown a wide gap between the apps. Implications: The recent development of mobile apps for hospital accessibility and consumer needs has shown a wide gap in the quality of apps, including information and aesthetic. Therefore, it is necessary to develop apps based on user interface(UI), user experience(UX) based designs that can promote the usefulness and convenience of apps while monitoring needs of consumers continuously.

현재 터치스크린을 활용한 기기와의 인터랙션이 전반적으로 널리 활용되어 스마트시계 또한 출시에 기존의 터치스크린 UI/UX를 그대로 적용하는 경우가 대다수이다. 하지만, 스마트시계의 경우, 필연적으로 기기가 작아질 수 밖에 없고, 그로 인해 장착된 디스플레이도 소형으로 나오는 경우가 많아 터치방식에서 오류 발생률이 높아질 수 밖에 없었다. 이 논문에서는 스마트시계에 탑재된 6축 센서를 활용한 인터페이스 방식을 제시한다. 이 방식은 기존의 터치 방식과 달리 작은 화면을 누를 필요 없이, 시계의 다양한 방향의 모서리 끝을 탭핑(Tapping)하여 신호를 구분하는 방식으로 스마트시계를 조작할 수 있도록 한다. 본 논문에서 제안되는 조작방식은 기존 방식보다 오류발생률을 줄이면서도 간편하게 사용자 이해가능성이 높고, 스마트시계에서의 조작환경(전화 및 문자 알림, 날씨 정보, 음악 재생 및 볼륨 조절 등)을 제어 시 유용하다. 또한, 출시된 스마트시계에도 기본적으로 내장된 센서를 활용한 인터페이스이므로 새로운 센서를 부착할 필요 없이 적용이 가능하며, 스마트 시계뿐만 아니라 스마트 디바이스의 경우, 기본적으로 자이로, 가속도 센서가 탑재되어 있어 타 기기에 대한 적용가능성 또한 높다.

우리 사회에서 개인이 복용하고 있는 약물의 종류와 수가 점점 늘어나고 있다. 약물의 사용이 증가하면서 때로는 치명적일 수 있는 약물 오남용 또한 빈번히 발생하고 있으며 특히 노년층과 같이 약품을 정확하게 구별할 수 없는 사람들은 더욱더 그 위험에 노출되어있다. 본 논문에서는 사용자가 간단한 사진을 찍는 행위를 거치면 약물의 정보를 제공하고, 복용법을 알 수 있는 모바일 애플리케이션에 관하여 기술한다. 이를 구현하기 위하여 세밀한 시각적 분류 (Fine-Grained Visual Categorization, FGVC) 기법과 광학 문자 인식 (Optical Character Recognition, OCR) 기법을 결합한 인공지능 모델을 사용하였으며, React Native 를 사용하여 운영체제에 종속되지 않도록 애플리케이션을 제안한다. 이 애플리케이션은 노년층에 친화된 UI/UX 로 디자인되었으며, 약물의 정보 제공 이외에도 개인 약물 관리, 주변 약국 길 찾기 등의 편의 기능을 통해 노년층에 삶의 질 향상을 기대할 수 있을 것이다.
