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.

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.

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.

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.

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.

The education applications for English learning have been developing consistently by utilizing the smart-phone owing to the development of internet and ICT. Smart technology based study platform, the mobile learning which enables for the students to study beyond the time and space is expected to bring forth new paradigm of education in tune with the environment change and trends. But it is found that the current applications are mostly the contents patterned for English study institution information with single channel or made for thinking study concept with only the simple language learning once they were checked. Therefore, the understanding on the English study process shall be changed and the study on the platform service is required by accessing in the viewpoint of thinking exercise learning. This study is purposed to explore the scope and strategy of mobile learning UX platform development and suggest the service model via prototype for English study.

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.

The artificial intelligence speaker market is in a new age of mounting displays. This study aimed to analyze the difference of experience using artificial intelligent speakers in terms of usage context, according to the presence or absence of displays. This was achieved by using semantic network analysis to determine how the online review texts of Amazon Echo Show and Echo Plus consisted of different UX issues with structural differences. Based on the physical context and the social context of the user experience, the ego network was constructed to draw out major issues. Results of the analysis show that users' expectation gap is generated according to the display presence, which can lead to negative experiences. Also, it was confirmed that the Multimodal interface is more utilized in the kitchen than in the bedroom, and can contribute to the activation of communication among family members. Based on these findings, we propose a user experience strategy to be considered in display type speakers to be launched in Korea in the future.

This paper is the UX-based technology strategy research which is a solution to how conversational AI can be ethically evolved in the Metaverse environment. Since conversational AI influences people's on-offline decision-making factors through interaction with people, the Metaverse AI ethics must be reflected. In the machine learning process of conversational AI, cultural codes along with user's personal experience data must be included and considered to reduce the error value of user experience. Through this, the super-personalized Metaverse service can evolve ethically with social values. With above hypothesis as a result of the study, a conceptual model of a forward-looking perspective was developed and proposed by adding user experience data to the machine learning (ML) process for context-based interactive AI in the Metaverse service environment.
