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.

Implementing UX design that meets user expectations has become an important variable that determines the prominence of smart home appliances. This study addresses the UX design evaluation issues in mobile application development of smart home appliances. As an experimental research subject, the UX design evaluation contents were set up for the mobile application of , the demand of which is surging recently. The purpose of the research is to explore the significance of the UX design user evaluation method in smart home applications, and to suggest how to achieve the mixing of quantitative and qualitative evaluation methods. The main findings are as follows. First, we found that user evaluation can positively impact the direction of UX design. Secondly, we found that the mixing of 'quantitative' and 'qualitative' methods works complementarily to UX design evaluation. Research implications are as follows. The UX design evaluation process can be performed efficiently as long as we distinguish between the roles of quantitative evaluation and qualitative evaluation. For example, through qualitative evaluation such as 'Honeycomb model', can be identified in terms of 'exploratory', and through qualitative evaluation such as 'in-depth user interview', can be identified in terms of 'assessment' and 'validation'.

Purpose The purpose of this study is to examine the customer experience of generative AI among office workers aged 30 to 40, investigating usability, usefulness, and affect, and understanding concerns and expectations. Design/Methodology/Approach This research used Q methodology to assess the customer experience of generative AI. Users are engaged in a problem-solving journey, and data is collected by having participants rank 36 statements based on usability, usefulness, and affect, referred to as the three goals of User Experience. Participants use a forced distribution table with a scale from -5 to +5 to indicate the subjective importance of each statement. The results identified four groups, reflecting different perspectives and attitudes toward generative AI. Findings Participants express overall comfort with generative AI, perceive AI as more knowledgeable in unfamiliar domains, but harbor doubts about AI's understanding. Disagreements emerge on AI replacing humans, the value of unique human roles, data confidentiality, fears of AI advancement, and emotional impacts. Identified four groups: Users who treat AI as a soulless assistant and are active in business use, Uncle users who want to use new technologies properly and are not afraid of technology, users who recognize the limits of AI despite its efficiency, and users who require strong verification in the future. It has the potential to guide future guidelines, ethical codes, and regulations for the appropriate use of AI. In addition, this approach lays the groundwork for future empirical analyses of generative AI.

This study aims to review the differences and distinctive characteristics between storytelling method of virtual reality contents and storytelling method of conventional contents instead of focusing on economic and industrial effects of virtual reality contents. As a specific target, this study discusses how existing storytelling method of webtoons as a single contents genre can be applied to virtual reality contents when webtoons are adapted into virtual reality contents. The purpose of this study is to find limitations and possibilities for the storytelling technique of virtual reality contents. The results of this study showed that the essence of storytelling in virtual reality contents is in three roles of the users of virtual reality. The users of virtual reality must play the roles of service user, audience of contents, and director of story. This is because the most important storytelling techniques in media contents like editing and change of camera viewpoint can no longer be forced in virtual reality contents. Storytelling techniques in virtual reality contents are much limited compared to the conventional contents in terms of user interaction, expansion of senses, and guarantee of freedom.

The purpose of this study is to verify the anthropomorphic design factors of pedagogical agents that can enhance user experience in learning foreign languages (English) through smartphones. In this study, when designing a pedagogical agent that delivers content, the presence or absence of the agent's image, the degree of human nature (HN), and role setting (leader vs. companion) among the anthropomorphic factors that influence facilitating learning, credibility, and engagement perception. As a result of the experiment, HN alone did not show a facilitating learning effect, and images and roles improved not only the facilitating learning effect but also other user experience factors. When HN factors were designed in combination with image and role factors, they were effective in overall user experience effects such as facilitating learning, credibility, and engagement.
