An Exploratory Study of Immersive Mixed Reality Interactive Interfaces in Smart Home Environments

In this study, we explore the design of immersive mixed reality interaction interfaces within smart home environments. Based on the sequence of interactions between users and smart home devices, we developed a three-level user interface display framework: the trigger level, operation level, and information presentation level. In the first study, we conducted a user experience evaluation of the trigger level interface presentation methods, focusing on time, error numbers, visibility degree, operability degree, and unobstructed sight degree. This research demonstrated user preferences for the interface triggering smart home devices. In the second study, we designed interfaces for two interaction modes: a slider interface based on pinch gestures and a button interface based on poke gestures. We evaluated the benefits and limitations of these interaction modes in controlling smart home devices by measuring the time, usability, and task load associated with each interface. Finally, we summarize four design recommendations to guide the future design of immersive mixed reality interaction interfaces in smart home environments.
