On November 5, 2025, our team interviewed a professor specializing in the Internet of Things (IoT). The discussion focused on practical challenges in daily ingredient management, differences in user needs across age groups when using digital management tools, priorities in system functionality and interface design, and strategies to enhance user acceptance and long-term engagement with smart ingredient management systems. The interview findings have been compiled in the appendix and serve as an important reference for subsequent system optimization and the development of our research conclusions.
