2007년 본격적으로 시장에 출시된 터치폰은 시장의 관심을 받으며, 휴대전화의 한 영역으로 자리매김하였다. 전세계 휴대전화 시장에서 터치폰이 차지하는 비중은 급속도로 증가하고 있다. 삼성전자는 시장에 후발주자로서 터치폰 시장에 진입하였음에도 불구하고, 2009년 3분기 기준 전세계 터치폰 시장의 23.9% 점유율을 차지하며 1위를 차지하고 있다.터치폰에서의 선전으로 삼성전자는 전세계 휴대전화 판매량의 20.3%를 달성하며 2위 자리를 확고히 하고 있다. 이러한 상승 추세는 지속될 것으로 보이며, 터치폰에서의 성공에는 TouchWiz UX가 중심에 있다고 할 수 있다. 본 세션에서는 TouchWiz UX를 통한 삼성 터치폰의 성공 전략에 대해 소개하고자한다. 우선 TouchWiz UX가 탄생할 수 있었던 배경으로서 당사의 디자인 철학이자 UX 다지인 철학을 간단하게 소개한다. "Creating Emotional Journey"라는 슬로건 아래 "Desire", "Intrigue", "Delight"라는 핵심철학을 공유하고 있다. 다음으로 TouchWiz UX를 성공 시킬 수 있었던 UX 추진 전략을 "Good UX 전략", "브랜드화 전략", "진화 전략", "확산 전략" 으로 나누어 소개한다. 첫째, Good UX 전략에서는 "Simple", "Robust", "Reliable"의 3대 원칙하에 사용성이 높고 감성을 자극하는 UX를 만들기위해 노력하였다. 둘째, 브랜드화 전략에서는 UX를 마케팅에 적극적으로 활용하여 TouchWiz라는 UX 브랜드를 탄생시켰다. 셋째, 진화 전략에서는 TouchWiz 1.0에서 2.0으로 진화하는 과정에서 핵심적인 부분은 유지하면서 발전시켜 나가는 전략을 선택하였다. 넷째, 확산 전략에서는 TouchWiz UX가 각기 다른 OS, Platform, 사업자에 따라 공통화, 차별화를 병행하여 확산하였다. 마지막으로, 내년에 소개될 TouchWiz 3.0에 대해 전략과 키워드를 간단히 소개한다.

The key to the success of IT services is to ensure user-oriented strategic planning and system design capabilities to accurately read the user's mind. In order to establish a stable UI/UX strategy that provides user-oriented service, estimating the size of the relevant market and predicting the growth potential should be given priority, but there is no research on this. Therefore, this study estimated the relevant market based on the 'SW market size (IDC Worldwide Blackbook.') As a result of estimating the amount and the number of cases, the planning and design area of UI/UX is lower than that of overseas market The results of this study suggest that it is necessary to systemize the establishment of UI/UX strategy that depends on individual competence so far, It is possible to make economic value judgments by standardization and quantification of UI/UX by establishing an opportunity to access the interface. From the technical viewpoint of application of the user's viewpoint on the existing interface, We expect to be able to lead the UX strategy management through the occasion of access to UI/UX. Identify needs and to demonstrate the value of UX strategy applied is significant.

Despite the development of technology and the increase in the spread of smart speakers, user satisfaction keeps decreasing due to conversational errors. This study aims to examine the effect of the self-repair strategy on user experience in the context of conversational agents of smart speakers. Scenarios were designed based on error situations, and participants were divided into two groups by task criticality. The results revealed that the agent's self-repair strategy has a negative effect on trust and perceived ease of use compared with performance without error. It also influenced adoption intention through interaction with task criticality. This study is significant in that it empirically investigated the effects of the self-repair strategy and the user experience factors related to the actual acceptance of the self-repair strategy.

Metaverse provides a simulated environment that can produce various values while conducting economic, social, and cultural activities in a digital society where the virtual and real worlds are connected. In this paper, the direction of technological progress is predicted by analyzing the characteristics of Metaverse services and their businesses. Technologies and latest researches for the realization of the Metaverse service platform are also explored. In addition, Metaverse Ethics to construct a sustainable Metaverse and Metaverse UX to increase users' service participation are also discussed. Moreover, the R&D promotion strategy for Metaverse services are presented.

In the future, infotainment systems are expected to play a pivotal role in mobility ecosystems connecting users and vehicles. This study draws user-experience factors from reviews of Android Auto, a car infotainment application, and analyzes factors that affect satisfaction. The user-experience factors of infotainment have been redefined based on previous studies. To analyze actual user-experience factors, topics are obtained, applied, and interpreted from user discourse through topic modeling. Sentiment analysis and logistic regression are used to determine positive and negative user-experience factors that affect satisfaction. Results of the empirical analysis show that Ease of Use and Understandability are factors that have the greatest impact on satisfaction, and Flexibility, Safety, and Playfulness are factors that have the most critical effect on dissatisfaction. Therefore, this paper suggests ways to improve the satisfaction level of the infotainment system, and establishes a strategy accordingly.

User Experience (UX) and Experience Innovation have been emphasized in the process of New Product Development (NPD). However, previous works which were conducted within the theme of UX mostly focused on the fragmentary aspects of user's experience in a specific usage-context only. For this reason, it is always hard to deal with questions on how to define the abstract concept of UX and how to apply this important keyword in actually NPD process both for satisfying potential users and for setting a market strategy. To address this issue, we focused on the fact that UX has an aspect of composition like pattern and structure. It means that we can understand the context of UX with clarifying characteristics of relations between user and experiential objects. Also, we referred to two sub-concepts of Complexity, Density and Centrality, as representative characteristics of relations in usage-context. Based on this theoretical background, we attempted to find UX design principles and concepts for NPD from the actual example cases of products and services in the real market. From these whole study process, we expect that our findings could have implications for academic and practical areas within the theme of Human-Centered Innovation.

본 논문은 메타버스 환경에서 문제가 대두되고있는 AI 윤리(ethic)를 배경으로 인터랙션을 통해 사람들의 온라인과 오프라인의 결정요소에 직접적으로 영향을 미치는 대화형 AI가 어떻게 윤리적으로 진화될 수 있을지에 대한 공학적 솔루션을 UX 관점으로 찾아보는 기술 전략 연구라고 할 수 있다. 연구의 가설은 AI 의 머신러닝과정에 개별 사용자 그룹의 경험데이터가 반드시 포함되고 고려되어야 AI 는 오류값을 줄이고 윤리적으로 대응할 수 있다는 전제이다. 이를 위하여 본 논문은 기존의 머신러닝과 대화형 AI 의 UX 관점의 다이아로그 플로우 등을 연구 분석하고 사용자 데이터들을 실험하여 메타버스 서비스 환경에서의 기존에 논의되고 있는 컨택스트기반의 AI 머신러닝 과정에 사용자의 정성적 경험데이터를 추가한 윤리적 UX 접근 개념 모델을 제안 하였다. 아직은 개념모델 단계이고 시스템에서는 지금까지 다르지 않았던 비정량적인 감정과 융합적경험을 어떻게 문화적으로 코드화 하고 시스템적인 랭귀지와 연결시킬 수 있을지에 대한사용자 연구가 후속연구로 진행될 예정이다.

A design which would let its users optimize their learning experiences accordingly to the diversification of learning platforms is needed. Especially with the expansion of mobile learning, a heuristic evaluation was used to evaluate the usability in order to provide learners with various learning methods and experiences according to the unique characteristics a mobile possesses. Therefore, we could conclude that systematic factors like information display, intuitiveness and conciseness do have a significant effect on users' attitudes.

With the active usage of digital media, the importance of and the interest in User Interface (UI)/User Experience (UX) have been increasing. This study proposes the development of design evaluation model to utilize the quality analysis model as a basis if there were to be a development of mobile education application. Main factors of the design evaluation model, which is based on User Value analysis, influence users' attitudes and intentions in continuing their uses of a mobile education application. The employment of the design evaluation factors onto the existing agile method's development stage, therefore, would provide an optimal UX environment for the application. This application not only will increase the satisfactions of consumers, but also will have positive impacts on their intentions in continuing their uses of a mobile education application.

With mobility-as-a-service(MaaS) drawing attention to its influence and ripple effect around the world, the mobility service market is currently growing rapidly mainly focusing on mobility sharing. In order to preemptively dominate the mobility service market following the full-scale spread of MaaS, it is important to first identify the recognition and experience of users in personal mobility sharing services, which are currently in the early stages of diffusion, and through which to understand the characteristics of potential consumers of the extended mobility service market. Therefore, the study aims to classify the user types of mobility service and establish a future user experience-oriented mobility service strategy using a subjectivity study method, Q methodology.
