Digital Experience Service Design for Intangible Cultural Heritage: A Case Study of the Hezhen Yimakan

This study takes the Hezhen Yimakan as a case and develops a research framework encompassing requirement identification, dimensional synthesis, multidimensional requirement evaluation, design translation, and experimental validation. User requirements were first elicited through field investigation and semi-structured interviews and then organized into three dimensions—interactive experience, emotional-aesthetic experience, and cognitive understanding—through exploratory dimensional analysis. The entropy weight method was subsequently used to examine the dispersion and information-discrimination capacity of individual requirement indicators, while direct importance ratings measured users’ subjective judgments of the importance of each requirement. Design response priorities were determined by integrating qualitative evidence, entropy-weight analysis, and direct importance ratings, and a digital experience prototype was developed accordingly. An intergroup comparative experiment showed that the optimized prototype outperformed the existing interface in overall user experience, willingness to sustain cultural interest, and task-completion efficiency. The findings demonstrate that entropy-based information weights and users’ subjective importance judgments should be clearly distinguished; combining both with qualitative evidence can provide more cautious and transparent decision support for the design of digital experiences for oral-tradition intangible cultural heritage.
