Exploring the key variables of Human-Computer Interaction (HCI) characteristics for smart home design/ Yan Yan, Natasya Khalil and Mohd Irwan Ali

With the rapid development of the Internet of Things and artificial intelligence technology, the smart home system has become an important
part of the modern living environment. Human-Computer Interaction (HCI), is a key factor of smart home user experience, the optimization of its mode and attributes is crucial to improve user satisfaction. Smart home system provides a convenient life experience, but the complex interaction mode and unclear interaction attributes may lead to user operation difficulties and affect user acceptance. Therefore, a further study of the mode and attributes of HCI is of great significance for the design of a more humanized intelligent home system. The purpose of this study is to explore the variables related to the characteristics and attributes of HCI in the existing smart homes. The key variables are extracted through an extensive literature review, collecting and organizing existing relevant studies of smart home HCI characteristics and attributes. A comprehensive framework of HCI characteristics is constructed based on the literature findings while the interactions are revealed through the constructed model towards theoretical support and practical guidance for future smart home design. The findings will help smart home developers and designers gain a deeper understanding of user needs in designing a more efficient, intuitive, and satisfactory smart home interaction system.
