A system design method for virtual ceramic creation oriented to authenticity representation: integration of Kano, QFD, and FAST approaches

With the rapid advancement of virtual reality technologies, the digital transformation of traditional ceramic crafts has become a key focus for innovative research. However, existing virtual ceramic creation systems largely remain limited to surface appearance and basic operations, with significant gaps in authentically reproducing core craft processes and cultural contexts. To address this challenge, this study proposes an integrated and systematic approach to user needs analysis and design optimization for virtual ceramic creation systems. Using the KJ method, eleven core user need categories and thirty-six specific design requirements were identified. These requirements were then classified and prioritized according to the Kano model. The FAST method was applied to decompose system functions and construct a functional framework. Finally, quality function deployment (QFD) was used to identify and prioritize five key quality characteristics: content creation and crafting, teaching assistance system, virtual assistant, user interface operations, and multisensory experience, clarifying their priority and central role in system development. Design requirements for the virtual ceramic system were analyzed across four dimensions: materiality, behavior, emotion, and sociality. Materiality is addressed through multisensory immersive experiences and physical material simulation to closely replicate ceramic texture and craft details. Behavior is supported by teaching assistance and virtual assistant systems to facilitate skill acquisition and provide real-time operational feedback. Emotion is fostered through diverse cultural styles and content generation, promoting cultural heritage and emotional resonance. Sociality is enhanced by multi-user collaboration and community interaction, strengthening user communication and co-creation. This study provides a systematic design methodology and theoretical foundation for the development of virtual ceramic creation systems, contributing to the advancement of digital ceramic crafts and the enhancement of user experience.
