Theme Filling the Central Hall -- Smart Home and AI Fusion: CES 2025 drew the attention of the global technology industry as a venue illuminating the future AI and smart home technology combination will bring. At this CES, AI is not remaining as a subsidiary technology but deeply fusing with smart home technology to establish itself as a core element of new residential environments. The combination of AI and IoT received attention for not just making users lives more convenient and safe but also for presenting solutions for energy saving and environmental protection. AI has been attracting attention at CES since 2017, continuing technological growth over 8 years to establish itself as a major theme. The smart home AI fusion theme occupied the Central Hall -- the most prestigious exhibition space at CES -- demonstrating that smart home AI integration is now the dominant technology narrative rather than a niche category. Key smart home AI demonstrations: ambient intelligence that learns household patterns without explicit user programming; predictive maintenance for appliances detecting failure before it occurs; energy optimization coordinating all home systems for minimum consumption; and security systems that distinguish between authorized and unauthorized presence using computer vision.
