The work aims to explore the transformation direction of the new interaction paradigm in the smart home scene with the idea of explicit-implicit integration in the context of the smart era. Based on the framework of the explicit-implicit interaction continuum, a systematic integration and comprehensive analysis was conducted by combining the advantages and disadvantages of explicit-implicit interaction, transformability and smart home product features. It was argued that explicit-implicit interaction was a key way to upgrade the experience of smart home products under the current technical dilemma. The necessity and feasibility of explicit-implicit interaction were clarified. Three explicit-implicit interaction design modes were proposed, and the ratio of interaction mode combinations in different interaction design modes was clarified, and design ideas for further interaction were proposed:explicit-implicit juxtaposition, dynamic empowerment and two-way delayed difference, so as to realize the coordination of the three interaction modes. The interaction design pattern and ideas proposed for smart home products with explicit and implicit integration respond to the current problems in the interaction design of smart home products and provide a reference direction and research path to promote the shift to a new paradigm of intelligent interaction.
