omputer and the Internet (online) services have rapidly been developed and evolved over the last 10 years. They also reduce time and costs in many parts of human life. Yet, a range of adoption and expression has been segmented as a piece of information is diversified. Particularly, while this segmentized information can be integrated according to fields, it is hard for users to aware it at a glance. Therefore, this study aims to improve and analyze programs that have been developed in a variety of ways from the existing unified design of GUI as the UIs of the Internet and programs have become accentuated recently so that it could suggest the importance of user-oriented UI designs.

We present a use. interface(UI) simulator for developing a mobile phone. This simulator consists of 3 major modules: Graphic Tool Editor, User Interface Software(UI), and Network Command Processor(NCP). The Graphic Tool Editor can design a virtual mobile terminal. The NCP sends a command to the phone and then receives its status from the phone after completion of the command. We can add or modify lots of features easily to the phone using the UI module. These modules can interact each other by sharing the common area in the memory. By doing so, these modules can exchange their status and data to operate in real-time. We have designed and tested a virtual prototyping phone for the LGP 3200 manufactured by LGIC by using the simulator. Through a series of experiment, we have believed that our virtual prototyping interactive simulator can do shorten its development and testing cycle by applying it in the early design phase.

In this paper, we present a mobile application for 'personalized customized learning' for children with articulation disorders using an artificial intelligence (AI) algorithm. A dataset (Data Set) to analyze, judge, and predict the learner's articulation situation and degree. In particular, we designed a prototype model by looking at how AI can be improved and advanced compared to existing applications from the UX/UI (GUI) aspect. So far, the focus has been on visual experience, but now it is an important time to process data and provide a UX/UI (GUI) experience to users. The UX/UI (GUI) of the proposed mobile application was to be provided according to the learner's articulation level and situation by using CRNN (Convolution Recurrent Neural Network) of DeepLearning and Auto Encoder GPT-3 (Generative Pretrained Transformer). The use of artificial intelligence algorithms will provide a learning environment with a high degree of perfection to children with articulation disorders, thereby enhancing the learning effect. I hope that you do not have any fear or discomfort in conversation by improving the perfection of articulation with 'personalized and customized learning'.

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.

핸드폰이 단순한 커뮤니케이션 도구에서 종합 엔터테인먼트 기기로 빠르게 진화되고 있으며 이를 뒷받침 하는 하드웨어와 네트워크 기술 역시 계속 발전해 나가고 있다. 또한 핸드폰이 다양한 기능을 제공하고 휴대폰에 내장된 어플리케이션의 종류가 많아 짐에 따라 UI에도 많은 변화가 일어나고 있지만 주로 사용성을 개선하는 기능적인 개선으로 치중되고 있는 상황이다. 본 연구의 목적은 핸드폰 UI를 새로운 관점으로 접근하여 '재미'라는 요소를 접목한 실험적인 UI를 기획하고 이를 적용하는 데 있다.

This study suggest the development direction of mobile environment by combining UX satisfaction index and UI guideline. In order to improve the satisfaction of viewers, in this study, we understand the mobile Internet broadcasting environment and application by combining UX and UI index. We present components which are suitable for internet broadcasting and calculate it on each broadcasting screen. Internet broadcasting application is for satisfaction of viewers. To make application which is satisfy viewer's needs, those advantages of applications should be combined.

In the last decade, the research of the usability of mobile phones has been a newly evolving area with few established methodologies and realistic practices that ensure capturing usability in evaluation. Thus, there exists growing demand to explore appropriate evaluation methodologies that evaluate the usability of mobile phones quickly as well as comprehensively. This study aims to develop a task-based usability checklist based on heuristic evaluations in views of mobile phone UI practitioners. A hierarchical structure of UI design elements and usability principles related to mobile phones were developed and then utilized to develop the checklist. In order to demonstrate the practical effectiveness of the proposed checklist, comparative experiments were conducted on the usability checklist and usability testing. Majority of usability problems found by usability testing and additional problems were discovered by the proposed checklist. It is expected that the usability checklist proposed in this study could be used quickly and efficiently by usability practitioners to evaluate the mobile phone UI in the middle of the mobile phone development process.

Growing smartphone usage in South Korea has also accelerated the pace of development of mobile games, but competition is intensifying as the market grows. As one of the factors for the success of the game in this mobile game market, UI has been presented, suggesting that the design of such mobile game UI should be approached in terms of designing the user's experience, along with its function, aesthetic expression, function-oriented design and information delivery before. In this paper, we propose an effective lobby layout of mobile RPG using experience among UX factors. Through the layout classification of Ernest Adams and Andrew Rollings, we selected 9 mobile RPGs in the 20th place of google play cumulative sales rankings and analyzed the layout of the lobby. As a result, the lobby layout of the game, which led the first market success of the mobile RPG genre, The result was that it became the standard of the boxed game. It can be interpreted that the lobby layout, which is similar to the game used previously by the user, is effective because low entry barriers and learning are unnecessary due to the experience of using the existing RPG. Future studies may produce a common layout of a broad genre if studies are conducted to measure the optimum UX for other genres than RPG.

A smart phone has an error if we design games on it because smart phone should be able to have input and output simultaneously through the screen. Using the existing layout of the game as a base for research, the layout was divided to four categories that are information area, informational appearance area, operation area and inutility area. Given the research results, we developed an authoring tool to design games for smart phones. Moreover, we applied the authoring tool to develop games and effectively reduce the developing time.
