Research on Human-Computer Interaction Design of Smart Home Products: Taking Smart Speakers as an Example

With the rapid development of artificial intelligence (AI) and the Internet of Things (IoT), smart home products have become integral to modern living environments. Among them, smart speakers represent a core device, acting as both control hubs for interconnected systems and interactive platforms between users and technology. This paper explores the human-computer interaction (HCI) design of smart speakers, emphasizing usability, natural interaction, and adaptive personalization. By analyzing design principles and recent innovations, this study examines how smart speakers enhance daily life while also confronting challenges such as privacy, accessibility, and trust. Drawing on contemporary research and case studies, the paper argues that effective HCI design requires balancing technological capabilities with user-centered needs. Findings highlight three critical dimensions: interaction modalities (voice, gesture, multimodal inputs), adaptive personalization, and ethical considerations of user data. The paper concludes that successful HCI design for smart speakers lies in developing seamless, inclusive, and trustworthy systems that not only respond intelligently but also align with human values.
