Abstract: The study aims to address the complexity of program settings in current smart washing machines. Based on user experience, a simplified interaction model is constructed by analyzing questionnaire surveys and user behavior data to identify key factors affecting operational efficiency. Proposals include optimizing interface hierarchy, applying scenario-based recognition technology, and implementing multi-channel feedback mechanisms. Prototype testing verifies the optimization effects, showing a significant reduction in user operation time and a notable improvement in satisfaction. The research results provide theoretical support and practical guidance for human-computer interaction design in smart home appliances.
