Technological applications of social robots to create healthy and comfortable smart home environment

The increasing demand for healthy and comfortable living environments has driven significant advancements in smart home technology. However, current developments often overlook the importance of users' social- emotional needs and the contextual dynamics within the home environment. This study proposes the integration of social robots as a promising solution to address these gaps. By enhancing smart home functionalities, social robots offer a more holistic approach to smart home design. A comprehensive literature review was conducted using the PRISMA methodology combined with large language model-based topic modeling to identify current research trends in social robotics. The analysis revealed five key research areas: (i) social- emotional intelligence, (ii) physical embodiment, (iii) elderly care, (iv) pediatric care, and (v) therapeutic applications. The study discusses how the core functionalities of social robots can enhance user experience by positively influencing the sensing, perception, and action layers of smart home systems. The findings suggest that the evolution of smart home technology should prioritize not only functional improvements but also the social and emotional well-being of users. Integrating social robots into smart homes will foster more human-centric, interactive, and satisfying living environments.
