In mobile content services like apps for smart mobile devices in specific, there has been a growing interest in evaluating UX quality to make sure that it provides better experience to users and consequently, secures competitiveness in a market. In that sense, usability testing has been considered as one method that enables designers and design managers to evaluate UI quality before they launch their service. However, those designers have been faced with a following fundamental question to be answere d : Is good UX design a good business? In other words, can well-designed service, which has good usability, actually satisfy target users and improve competitiveness in a market? There is no doubt that usability is one important factor perceived by users. However, it has a limit in terms of evaluating UX quality in macro level, as it mostly focuses on ease of use and efficiency of performing tasks, but does not cover other possible experiential factors, which also can be perceived by users, such as market situation and preexistence experience. Therefore, this research aims to identify key experiential factors in using mobile content services, and establish service UX index model that enables to measure perceived user satisfaction, and identify how UX design contributes to the satisfaction in quantitative way.

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.

Recently, interest in home training and changes in lifestyle are expanding the market in the healthcare field, and high value-added fashion products reflecting the dumbbell economy phenomenon are being released. This study had the following objectives: to investigate the possibility of developing a fashion item that can be applied to the dumbbell economy phenomenon; to develop the UI/UX of a smartphone application for beginners who wish to work out their upper and lower bodies regardless of time and space; and to create a wearable customized smart athleisure fashion device. First, the study identified factors related to exercise methods, breathing techniques, and range of exercises for beginners by investigating the postures of workouts of the upper and lower bodies by angles. Based on the results, the study collected empirical data through a user needs analysis from muscle strengthening exercise experts to verify the significance of the study and use as fundamental data. Second, the study developed the UI/UX of a smartphone application with three different contents: counting, suggesting exercise postures, and providing exercise calendars. Further, the study analyzed necessary user-centered concepts and characteristics in terms of design and technology and developed a wearable customized smart athleisure fashion device based on the results.

Design of the past focusing on molding and system is gradually changed into design focusing on users that reflects design philosophy considering users, and especially, the importance of User Experience Design that is to offer the best experience in using some products or services is realized. This study accessed design based on data having a low effect on function of wearable among changes that UX Design should consider in IoT generation. I think the data is diverse and many existing social commerce app, similar to the layout of the data in IoT devices based on the layout of the interface.Apps that data based model to analyze the layout. and the structure of the UX design were summarized.

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.

Voice interactions are particularly effective in applications targeting the digital underprivileged who are not proficient in the use of smart devices. However, applications based on open APIs are using voice signals only for short, fragmentary input and output due to the limitations of existing touchscreen-oriented UI and API provided. In this paper, we design a conversational voice interaction model for interactions between users and intelligent mobile/IoT applications and propose a keyword detection algorithm based on the edit distance. The proposed model and scheme were implemented in an Android environment, and the edit distance-based keyword detection algorithm showed a higher recognition rate than the existing algorithm for keywords that were incorrectly recognized through speech recognition.

Recently, with the attention of future vehicle technology, automobiles that are influenced by user experience(UX) are regarded as living space. However, the concept of term, definition, and constituent factors of driving experience have not been established so far. The purposes of this study are to define driving experience in terms of UX and to extract experience factors. We conducted the 18 drivers interviews and studied literature reviews. The collected interview data was analyzed by bottom-up method based on the grounded theory. And we reconstructed it through the top-down approach, based on the results of the literature review. As the result, the 'driving experience' is a concept that means all the emotions, perceptions, and cognitive outcomes on the basis of personal characteristics that drivers have in anticipation of the driving situation from the start to the destination Respectively. Nine factors that constitute driving experience were extracted by 'internal UI factors', 'environmental factors' and 'user related factors'.

최근 들어 차량은 단순히 이동을 위한 수단에서 벗어나 정보통신 기술과 융합되면서 콘텐츠를 소비하는 공간의 성격을 가져가고 있다. 자동차도 하나의 컴퓨터처럼 기능하게 되면서 차량 인포테인먼트의 역할이 차량 사용 경험에 중요한 요소로 자리 잡게 되었다. 그러나 교통수단이라는 특수한 환경임에도 불구하고 다른 환경에서 콘텐츠를 제공하는 형식과 차별화 없이 차량용 디스플레이에 맞춰 UI만 변경된 형태로 서비스가 제공되는 모습을 발견할 수 있다. 이에 본 연구는 문헌 조사 및 사용자 인터뷰를 통해 현재 차량 인포테인먼트 사용 행태와 보완점을 발견하여 개선 방향을 모색하고자 하였다. 사용자들이 차량 내에서 각기 다른 이용 패턴을 반복해서 실행하는 과정에서 인포테인먼트의 개인화 서비스에 대한 니즈가 있음을 확인하였고, 개인화 서비스를 통해 맞춤형 정보를 제공함으로써 새로운 가치를 만들어 낼 수 있음을 제시하고자 하였다.
