Design Resource Deployment for Virtual Fitting Applications in the Era of Digital Fashion: An Analysis Based on Kano-QFD

Virtual fitting applications have brought new vitality and immersive experiences to the fashion industry. As users adapt to the new fashion consumption experience enabled by virtual fitting, their demands are becoming increasingly diverse and complex. Therefore, it’s essential to deeply understand real user demands and use design resources effectively to meet these demands. This study assesses virtual fitting products on the market using smart data analysis techniques. Through panel group interviews, we’ve identified and preliminarily assessed user demands. We’ve categorized and prioritized these needs using the Kano model and transformed them into concrete design requirements using the Quality Function Deployment (QFD) method, establishing a system of design requirements. These requirements fall into three categories: visual design, interactive design, and emotional design. Each category includes core, secondary core, and peripheral core requirements. Eight core design requirements, such as personal image customization, extensive accumulation of apparel model libraries, and brand fan engagement were identified as top priorities for implementation. Eight secondary core design requirements, including realistic digital fabric rendering effects, real-time updates of the latest apparel models, and sharing of virtual fitting images should be integrated into design practices as resources allow. Nine peripheral core design requirements, like apparel aligning with mainstream aesthetic preferences, customizable avatar body dimensions, and minimalist user interface design can serve as references for inclusion in design practices. This research provides essential theoretical support for resource allocation in the design and iteration of virtual fitting applications, offering design solutions to meet the multifaceted real user demands in the rapidly changing field of digital fashion.
