Abstract : With the rapid spread of generative artificial intelligence, ChatGPT, Claude, and Gemini have continued to expand their applications as representative conversational AI platforms, while users share diverse usage experiences and information through online communities. This research compared and analyzed user interests and semantic structures related to generative AI platforms by conducting text mining-based network analysis on Korean online community data collected between January and June 2026. Based on the preprocessed text data, TF-IDF and CONCOR analyses were applied to identify key terms and semantic structures for each platform. The results showed that user interests across all three platforms were commonly centered on generative AI applications and service use. ChatGPT exhibited a usage-oriented semantic structure, Claude a specialized-use semantic structure, and Gemini an expanded-use semantic structure. These findings indicate that user interests and semantic structures formed in online communities may vary depending on platform characteristics and usage purposes. This research empirically identified differences in semantic structures and user interests among representative generative AI platforms and provides foundational data for understanding user experiences and service strategies of generative AI platforms.

Abstract : This study explores the reception and diffusion mechanisms of territorial identity narratives using AI-generated content (AIGC) within a multilingual YouTube environment through content analysis. A total of 2,415 commentsthe Dokdo Korea channel's video <Dokdo is Korea’s Honmoon> were coded across five reception stages and five engagement types. Identity identification constituted the highest reception proportion (36%), while only 4.8% of viewers recognized the AI production method with critical responses limited to 0.2%, demonstrating a ‘message primacy’ phenomenon. The channel operator's approximately 80% response rate facilitated subsequent viewer participation, and differences in reception framing between domestic and international audiences as well as generational pathway diversity were observed. This study proposes message primacy as a new conceptual framework for understanding public-interest content reception in the AIGC era and suggests that creator-led territorial discourse can function as a model for platform-based cultural diplomacy.

Abstract : This study aims to propose UI/UX guidelines to alleviate user anxiety and enhance satisfaction arisingautonomous AI agents independently judging and executing complex multi-step tasks without explicit user intervention. As the autonomy of AI agents is maximized, users are prone to losing a sense of control over the syste due to the advanced black box phenomenon, which can lead to decreased trust and service abandonment. To address this, this study established the timing of interrupt authorization granting and the level of visual feedback as independent variables. A two-way repeated measures ANOVA was conducted on 60 subjects to measure changes in user control, cognitive load, and syste trust resultingthese factors. The experimental results revealed that the highest level of control was maintained when immediate interrupt authorization was provided at the agent's task transition points and when uncertainty exceeded a threshold, and when structured state tracking feedback based on stepwise information deepening was provided. Beyond merely improving algorithmic precision, the findings of this study will provide quantitative and practical guidelines for the HCI field by establishing three essential UI/UX design frameworks that must be considered when designing autonomous AI agent systes.

Abstract : This study addresses a structural gap in existing user experience (UX) research by proposing a culturally situated conceptual model for emotional experience design (EXD) in AI-mediated learning and play environments for Generation Alpha children in East Asian contexts. As AI becomes an embedded component of children's daily educational and recreational lives, the emotional dimensions of interaction — curiosity, trust, relational engagement, and critical awareness — have emerged as determinants of sustained participation. Yet existing frameworks largely prioritize functional efficiency over emotional responsiveness, and few account for the sociocultural specificity of East Asian educational environments characterized by high academic expectations, performance-oriented evaluation, and Confucian relational values. To address this gap, the study employed a two-phase methodology. The first phase comprised a systematic literature review across four academic databases — EBSCO, CHAINS, Airiti Library, and CNKI — yielding a corpus of 15 documents analyzed through AI-assisted affinity mapping. The second phase consisted of naturalistic observation and Focus Group Interviews (FGI) with eight South Korean elementary school children (4 male, 4 female) aged 10 to 11, conducted over 16 weeks. Analysis of the empirical data identified six affinity clusters representing the core emotional experience patterns of Generation Alpha children in AI interaction, which were subsequently mapped onto four conceptual dimensions: Technical, Experiential, Emotional, and Ethical. The resulting EXD model structures these dimensions as a progressive foundation in which each layer constitutes a necessary condition for the next, while the uppermost dimension — Ethical Transparency — feeds back to reinforce the entire structure. The model contributes a theoretically grounded and empirically informed framework for child-centered AI UX design that is responsive to the sociocultural conditions of East Asian educational contexts, and serves as a foundation for future empirical validation and design application.

Abstract : The goal of this research is to explore the applications which used Inclusive Design Theory can enhance the mobile applications’ usability for users with visual impairments. While a lot of current mobile applications offer assistive technologies like screen readers, these features often fall short of offering entire user-oriented experiences and user involvements. Thus, this study intends to research how the principles of inclusive design can improve the overall mobile applications’ usability for users with vision impairments. In order to accomplish this goal, this research examines the Inclusive Design Theory’s theoretical concepts and usability in the design of mobile application for visually impaired users. Moreover, the earlier researches associated with inclusive design and accessibility design are evaluated to identify the constraints of traditional accessibility-centered approaches. Additionally, a user evaluation is conducted according to the derived criteria to investigate the mobile application interfaces’ usability. This study proposes that mobile applications designed based on Inclusive Design Theory will positively improve overall usability compared to traditional applications which are mainly focused on accessibility. The results show that inclusive design-based interfaces show enhanced usability in terms of user control, interface clarity and task efficiency.

Abstract : As large-scale visual effects (VFX) filmmaking becomes common, the importance of pre-visualization processes that concretize directorial intent before shooting is increasing. However, while research on previs, which deals with creative judgment, has accumulated, academic discussion on the practical contribution of techvis—which converts the previs-defined plan into the physical conditions of the actual shooting site—is scarce. This study aims to clarify how and how much techvis, as an offline 3D simulation and measurement process based on Maya, contributes to the spatial (art) and Cinematographic procedure (camera) optimization of large-scale VFX film production. Using three sequencesthe film “Omniscient Reader:The Prophet” in which the researcher directly participated, this study proposes an evaluation matrix that cross-analyzes the contribution of techvis on two levels: mechanism (how) and observed effect (how much). The analysis shows that techvis contributes by pre-implementing not-yet-realized elements as measured-scale 3D data, thereby controlling trial and error at the shooting site in advance, and that the pre-produced outputs were reflected in the final results without significant modification. This study is significant in that it re-illuminates the industrial value of the techvis process, which handles physical data, even in an environment where generative AI-based video production technology is spreading.

A Study on Film Re-creation Through Generative AI-Based De-aging and Deepfake Technologies
Abstract : Recent advances in Generative Artificial Intelligence (Generative AI) have significantly transformed film production. In particular, de-aging and deepfake technologies have emerged as key techniques for realistic facial reconstruction and age transformation, enabling new forms of film re-creation while preserving character identity and narrative continuity. This study examines the technological and aesthetic significance of Generative AI-based de-aging and deepfake technologies through Walter Benjamin's concept of aura, related image and video generation technologies, and the mechanisms of de-aging and deepfake techniques. Representative film case studies are comparatively analyzed to investigate their applications and cinematic effects. This study highlights that Generative AI-based de-aging and deepfake technologies have evolved into core creative tools for film re-creation and performance. Their applications are expected to expand across classic film restoration, digital actor creation, film remakes, and various forms of content production.

Phased Paradigm Transitions and Formability Changes in Generative AI-Based 3D Animation Production
Abstract : This study investigates the structural changes that generative AI technology brings to 3D animation production paradigms and character formability, and formalizes the direction of creator reskilling. Historical document analysis, measurement of outputs using the researcher-developed Formability Analysis Rubric (FAR), and expert in-depth interviews were conducted sequentially. Results confirmed that the production paradigm has undergone discontinuous transitions through analog, digital, and computational stages, with creative agency sequentially reorganized into physical technical competency, parametric control competency, and formative curation competency. A structural reversal was identified in the computational paradigm, where visual icon repetitiveness was remarkably high while silhouette consistency was lowered; through integrating quantitative and qualitative findings, the Creator Reskilling Model (CRM) composed of a three-layered dynamic cyclic structure of transferable, new, and critical competencies was derived. This study develops a 3D character domain-specific formability measurement tool (FAR) and a practice-based reskilling model (CRM), contributing to the redesign of creator education curricula and the establishment of content quality evaluation standards in the generative AI era.

Development of PBL-based Immersive Visual Content Production Curriculum
Abstract : This study applied Problem-Based Learning (PBL) to the education of immersive content production and qualitatively analyzed its educational effects. With the advancement of XR technologies such as Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR), immersive content has emerged as a core medium across diverse industries, increasing the demand for creative, convergence-oriented practitioners. However, while research on the use of immersive content is active, studies on its production curriculum remain scarce, and there is a need to establish a generalizable teaching–learning model that does not depend on the competencies of individual instructors. Accordingly, on the grounds of the expanding immersive content market, the shortage of curriculum research, and the field's demand for a systematic curriculum, this study aims to develop a PBL-based curriculum for producing immersive content and to explore its feasibility and educational effects. To this end, the researcher developed instructional materials by personally producing immersive content, refined the curriculum by incorporating expert feedback, and applied it as PBL-based instruction in a major course over one semester (15 weeks). Rather than relying on standardized instruments for statistical verification, changes in learners' problem-solving competency, creativity, and collaboration were explored by collecting and qualitatively analyzing the data generated during the course—reflection journals, task performance plans, project outputs, and survey responses—through the lenses of self-direction, creative design, and team-based communication. The analysis indicated a tendency for learners' self-directed learning attitudes, creative design attempts, and teamwork-based communication to appear positively throughout the PBL-based instruction. These findings suggest that PBL can serve as an effective teaching–learning strategy in education requiring complex production processes such as immersive content, and that this study offers a theoretical and practical model for developing curricula aimed at cultivating creative, convergence-oriented talent. However, because the analysis of effects rests on the interpretation of qualitative data, future research should verify these effects more ively through quantitative validation using standardized instruments and pre-/post-tests.

A Typological Study of Media Facade Expressions for Restoring Place Identity in Tunnel-shaped Spaces
Abstract : Linear urban infrastructure such as tunnels and underpasses, developed for functional efficiency, has increasingly become non-places characterized by physical enclosure and visual monotony that provoke psychological discomfort and pedestrian avoidance. In particular, the tunnel vision phenomenon occurring inside tunnels amplifies psychological distance and fear of crime, intensifying pedestrians' avoidance of the space. This study investigates media facades as an effective medium for restoring place identity in such spaces, classifying their expression types into three categories—functional lighting-based, narrative-based, and interaction-based—and deriving practically applicable design directions. Results confirm a staged place-making structure of perceptual expansion, cognitive immersion, and social interaction, leading to three design directions: systematic visual rhythm, adaptive luminance design, and site-specific narrative integration. In particular, the staged transition of color temperature according to the pedestrian sequence is presented as a concrete design proposal for practical application. This study contributes a theoretical and practical framework for media-based spatial design in the regeneration of underutilized urban infrastructure.

Abstract : Night tourism plays an important role in promoting the growth of the nighttime consumption economy, enhancing urban cultural attractiveness, and facilitating urban development. This study selected five representative night tourism destinations in Shanghai as research sites and collected and analyzed data through questionnaires and in-depth interviews based on five dimensions: night atmosphere, positive emotions, flow experience, tourist satisfaction, and revisit intention. The study aims to examine the significance of night atmosphere and its influencing mechanism in shaping tourists’ experiences within the context of night tourism. The results indicate that night atmosphere is an important factor influencing tourists’ night tourism experiences. Night atmosphere consists of four fundamental elements, including design, ambience, employee elements, and spatial layout. The visual, auditory, and situational stimuli generated by ambience elements within the night atmosphere can evoke tourists’ positive emotions, such as pleasure and excitement, while fostering immersive flow experiences, thereby influencing their positive evaluations of tourism destinations and future behavioral intentions. Moreover, the development of night tourism destinations should go beyond the construction of basic atmospheric elements and focus on enhancing tourists’ positive experiences through lighting design, cultural expression, interactive experiences, and the integration of local characteristics. This study provides theoretical foundations and practical implications for creating distinctive night tourism atmospheres and improving tourist experiences in night tourism destinations.

A Study on the Establishment of a Visitor-Centered Online Museum Platform
Abstract : As digital transformation accelerates, museums are shiftingprovider-centered institutions to platforms focused on visitor experience. Accordingly, this study aims to identify the key components and development strategies of a visitor-centered online museum platform. A multiple-case study was conducted on Netflix, the Thyssen-Bornemisza National Museum, CosmoCaixa, and the EduCaixa integrated education platform, based on platform ecosystem theory and customer experience theory. The analysis identified four key components: data-driven hyper-personalization, visitor-centered experience design reflecting visitors' contexts, participatory interaction, and an integrated inter-institutional network. Based on these findings, the study proposes personalized content and docent services driven by visitor data analysis, online–offline participatory programs, and systems for sharing information, resources, and feedback among museums. This study is significant in redefining the online museum platform not merely as a channel for providing digital content, but as an ecosystem in which visitors and various cultural actors interact and co-create value.
