A Design Evaluation Protocol for Measuring User Interaction, Visual Preference, and Cultural Recognition in Digital Ethnic Interfaces

The evaluation of digital ethnic interfaces necessitates a comprehensive approach that quantifies both functional usability and cultural communication efficacy. This protocol details a mixed-methods, within-subject experimental framework designed to measure user interaction, visual preference, cultural recognition, and cultural identification. The procedure utilizes three structured prototype levels: a baseline information interface, an ethnic visual-enhanced interface, and a cultural narrative-enhanced interface. The protocol specifies the rigorous collection and integration of objective task performance metrics (including completion rates and interaction duration), standardized psychometric assessments (incorporating the System Usability Scale and multidimensional preference instruments), and semi-structured interview outcomes. Application of this methodology to a cohort of 140 participants verified its capability to precisely isolate the interaction effects of visual and narrative variables. Quantitative execution of this protocol demonstrated that cultural narrative-enhanced configurations yielded a cultural symbol recognition rate of 92.1% and a content comprehension rate of 91.4%. Furthermore, structural analysis derived from the protocol metrics established that cultural recognition serves as a primary statistical predictor of cultural identification. By integrating objective interaction logging with standardized subjective measurements, this protocol provides a reproducible methodology for systematically assessing interface efficacy within digital heritage systems.
