Abstract: Aimed at the content transfer problem of cross-device interaction in smart homes, the visibility of interaction was defined in terms of reference type and number of artifacts, and on this basis, four referential domain formulation methods (physical, coupled physical and digital, digital, and natural) were proposed. The “Wizard of Oz” experiment facilitated the exploration of the impact of four methods on the user experience in a single task scenario and primary and secondary task scenarios. The experimental results show that the difference in the user experience of different methods in the same scenario and that of the same method in different scenarios. Conclusions are drawn from two aspects: ① The differences in the method: the physical is efficient and interesting, the coupled is the most interesting but not very practical, the digital is the most practical but too conventional, and the natural is the most practical in the primary and secondary task scenarios. ② The difference in scenarios: users focus on practicality in the primary and secondary taskscenarios, while in the single task scenario they focus on both practicality and hedonism.
