이미지 생성형AI ‘Motiff’의 UI 디자인 프로세스 적용 효과 연구 — 디자인 효율성과 일관성 평가를 중심으로 = A Study on the Application Effects of the Image-Generating AI ‘Motiff’ in the UI Design Process — Focusing on the Evaluation of Design Efficiency and Consistency

다국어 초록 (Multilingual Abstract)

With the rapid advancement of generative artificial intelligence (Generative AI) technologies, the scope of AI application in the design field has expanded from visual ideation to process optimization and normative management. Motiff (妙多), China’s first AIGC tool specialized in UI design (hereafter referred to as “Motiff”), integrates AI-based duplication, layout generation, and consistency-checking functions, thereby contributing to improvements in design efficiency and visual consistency. This study examines the effects of AI tool utilization within the UI design process, with a particular focus on Motiff, and emphasizes two key dimensions: design efficiency and visual consistency. To this end, a repeated-measures within-subject experimental design was conducted with 30 participants, who completed identical UI design tasks under both AI-assisted and manual design conditions. Quantitative analyses of task completion time, consistency evaluation, and user satisfaction revealed that AI-assisted design significantly reduced task duration and demonstrated superior performance in terms of visual normativity and consistency. This study empirically verifies Motiff’s potential to enhance the UI design process and further discusses the application directions and limitations of AI-based UI design tools, offering insights for the development of human–AI collaborative design workflows.
