HomeView: Automatically Building Smart Home Digital Twins With Augmented Reality Headsets.

ABSTRACT Digital twins have demonstrated great capabilities in the industrial setting, but the cost of building them prohibits their usage in home environments. We present HomeView, a system that automatically builds and maintains a digital twin using data from Augmented Reality (AR) headsets and Internet of Things (IoT) devices. We evaluated the system in a simulator and found it performs better than the baseline algorithm. The user feedback on programming IoT devices also suggests that contextual information rendered by HomeView is preferable to text descriptions.
