This study was conducted to improve the use experience of elderly people in fast food kiosks which are actively utilizing 'un-tact' technology. First, the Kiosk design analysis criteria were discussed through literature research. Then, the UI screens of McDonald's, Lotteria and Burger King, which are currently serving kiosks in Korea, were divided into colors, layouts and buttons. Next, the usability evaluation and survey of the elderly revealed problems with the interface design of the current kiosk. As a result, older people do not recognize buttons without an outline as buttons, and errors occur when layout changes or when viewing is complicated. In addition, horizontal navigation and vertical layout menus were error-free, and the design of buttons was error-free with the same color for the same function. Research shows that the Kiosk UI design is preferred by older people. First, buttons in the form of outline or solid are recommended. Second, vertical binding of buttons combined with images and text is recommended. Third, the screen layout should be consistent with the direction of view flow and manipulation, and should avoid increasing the number of menus and information. Fourth, page navigation is recommended in horizontal form and menu arrangement is vertical form. Finally, buttons that perform the same function are efficient for buttons to use the same color, and for different functions, applying a complementary colors can reduce confusion.

More than 80% of the deaths in Korea are due to chronic diseases. Mobile applications continue to emerge where IT companies and medical hospitals work together to manage chronic diseases. In recent years, the development of artificial intelligence chatbot has been under way to improve the efficiency and convenience of management. Since the chatbot process the conversation by a dialogue, users who are familiar with the GUI-based environment may not be familiar with accessibility or usage. In this paper, we analyze UI / UX of the mobile application that manages diabetes in chronic diseases, and present the UI / UX design of chatbot through this result.

This paper shows the need to study the commercialized color book game screen composition and manipulation interface type in order to enhance the utilization of the serious game mobile coloring book game, which is utilized from the learning of color sense in modern people and children to the hobby life of adults or old people. For the healing of modern people, we are going to look at the design configuration of game screen interfaces in simple and fun mobile coloring book games, and propose a new way to improve interface design that improves uncomfortable design by organizing and analyzing basic interface UI design types.

제품과 사용자의 관계를 생각해 볼 때, 비록 하나의 제품을 두고 보더라도 매우 다양한 특성의 사용자집단이 존재 함을 알 수 있다. 이러한 사용자집단들은 각기 서로 다른 사용상의 특성과 니드(needs)를 가지고 있다. 이러한 제품 사용환경에서 디자이너들에게는 제품의 사용자들은 어떠한 분류가 있으며, 그들 각각은 어떠한 사용상의 특성을 가지고 있는지를 알아내 디자인에 반영하는 것이 중요환 디자인 활동이 될 것이다. 따라서 본 연구에서는 사용자 를 사용의 관점에서 관찰하여 사용자행위의 근간을 이루는 규칙의 정확도, 행위의 속도, 문제해결의 속도를 기준 으로 사용자를 분류하고 이를 토대로 사용자의 사용상의 특징을 밝혀내었다. 그리고 각 사용자집단별로 디자인 가 이드라인을 추출해내므로서 사용자분류를 통한 사용자 인터페이스 디자인의 가능성을 제시하였다. 본 연구에서 제 시된 사용상황에 존재하는 다양한 사용자들을 고려할 수 있는 방법은 좀 더 체계적이고 효과적인 사용자 인터페이스 디자인을 수행하는데 도움이 될 것으로 예상된다.

The current web implementation largely falls into process-oriented and object-oriented methods. Both ways implement the programs to be used for simple design of external outfit and auxiliary function of hybrid webs and it might lead to cost problems arising from waste of time and man-power to develop with it. Therefore, managed structural system programming which can be applied under .NET framework is suggested in a bid to solve these problems. The structural system design method under .NET environment by applying CS concept prefers to adopting the optimized design configuration suited to proper interfaces of UI configuration, which offers the environment to maintain the inheritance relationship by taking form of the balanced class allotment by domain, and continue to keep the connectivity between UX and UI which leads to application of interface of UX objects as form of objects through connection with objects in class design process. This development method enables programs to be implemented focused on representation methods of UI and UX, and helps relieve much of the burden on development costs.

The Learning Models including the design principle about web 2.0 use in education has been recently presented. In types of web 2.0 tools, blogs are the best tool that reflected the trends of web 2.0 and these are able to share a lot of information and contents. To invent new learning methods involving web 2.0, this study aims to get the results about effectiveness of learning performance on a supplementary learning tool based on blog using learner-centric UI/UX design in higher education. As a study tool, installation-type blog that can be designed as user-centric system is applied to experimental environment. This study presents the conclusion that supplementary learning tool based on blog using learner-centric UI/UX design influences on learning achievement and learning flow through the analysis of questionnaire results of learners, learning evaluation score of learners and assignments evaluation score of learners.

This study analyzes the lobby UI of the baseball manager game based on the mobile platform and proposes an optimized lobby UI. The UI layout-based detailed icons and button interactions in the four game lobbies are compared and analyzed by comparing and analyzing the common points and differences to finally calculate the optimized UI composition. Furthermore, based on the analysis, we intend to propose a lobby UI optimized for user-centered design.

The purpose of this study is to empirically verify how UI usability of mobile healthcare applications affects the perception of technostress and continuous use of elderly users. Through this, the effect of UI usability of mobile healthcare applications on technostress and continuous use intention was demonstrated for 199 people aged over 60. As a result, all four sub-factors of UI usability had a significant effect on technostress, and the magnitude of the influence was found to be in the order of content, process, design, and system. On the other hand, it was found that technostress had a significant effect on the intention of continued use. Through the above results, a UI design strategy that can lead to continuous use by relieving the technostress experienced by the elderly was suggested. This provides academic and practical implications for the future development and service direction of mobile healthcare applications for the elderly.

UX (User Experience) Design was an interdisciplinary approach in humanities, engineering, science and design. We classified the roles of user experience; requirement analysis which are user research, constraints analysis and direction analysis, concept design, information architecture, physical UI, graphical UI, sound UI, Olfactory UI, prototype, evaluation, launch, localization, and knowledge management/UI DB. User research methods were classified by the relation of designer, user, and product/service. We reviewed three issues of UX design; complexity management, efficiency management, and mapping management.

In this study, we found that the design can be configured according to the visual weight in the design of the interface. First of all, interface design has gone through the era of squeeze morphism to express depth and dimension by borrowing part of material design or head design from flat design. This is due to the characteristics of metro UI and flat design, which are difficult to express depth and dimension, but in material design, there was no separate device for inducing eyes, so Gestalt theory showed the principle of visual weight. Positive and negative, the size and placement of regions, proximity, closure, and notion were closely related to visual weight and orientation, and in some cases, it could be applied to the interface.
