The development of IoT, AI and sensor communication technology has led to the emergence of diverse interactive scenarios, with intelligent natural interactive interfaces becoming a common feature of smart home interactive interface design. However, the influence of traditional design methods and systems limits the ability of current designers to fully absorb new technological elements, preventing them from optimising product functions. In order to address this issue, this study has initiated an exploration of smart home interactive interface design methods. The researchers extracted 21 heuristics for smart home interactive interface design (DHS) from exemplary design cases and employed these in practice to assess their efficacy. They then summarised the model of the DHS for smart home interactive interface design.
