"Sensitivity" is the most important UI design principle for XAI interfaces, with a weight of 0.3296, meaning that how responsive and adaptive the interface is to user needs should be the top priority when designing AI explanation systems for non-expert users.
"Flexibility" is nearly as critical as sensitivity (weight = 0.3014), suggesting that AI explanation interfaces should allow users multiple ways to interact with and understand AI decisions, rather than forcing a single explanation approach.
Current XAI design guidance lacks clear prioritization, leaving practitioners uncertain about which design principles matter most and how to allocate their design resources effectively—this research provides the first empirical weighting of design principles to address that gap.
Non-expert users have distinct UI needs for understanding AI, as the study specifically identified five user experience standards for people without technical backgrounds, indicating that one-size-fits-all explanation interfaces may not serve general audiences well.
User interface design is critical infrastructure for responsible AI, functioning as "a crucial link between XAI and users," meaning that how explanations are presented visually and interactively may be just as important as the explanations themselves for building appropriate trust and understanding.
With the widespread application of artificial intelligence(AI), the explainable AI (XAI) field has undergone a notable resurgence. In this background, the importance of user experience in XAI has become increasingly prominent. Simultaneously, the user interface (UI) serves as a crucial link between XAI and users. However, despite the existence of UI design principles for XAI, there is a lack of prioritization based on their significance. This will lead practitioners to have a vague understanding of different design principles, making it difficult to allocate design space reasonably and emphasize design focal points. This paper aims to prioritize four design principles, providing clear guidance for UI design in XAI. Initially, we conducted a lightweight summary to derive five user experience standards for non-expert users in XAI. Subsequently, we developed four corresponding webpage prototypes for the four design principles. Nineteen participants then interacted with these prototypes, providing ratings based on five user experience standards, and We calculated the weights of the design principles. Our findings indicate that, for non-expert users, "sensitivity" is the optimal UI design principle (weight = 0.3296), followed by "flexibility" (weight = 0.3014). Finally, we engage in further discussion and summarization of our research results, and present future works and limitations.
