Many Internet of things (IoT)-based smart home products are being released according to the safety, convenience, and economic needs of residents in the space. However, IoT-based smart home services in South Korea are currently presented with scenarios for medium to large households with more than three to four people. Therefore, research on system design based on the home lifestyle of single-person households is needed. Methods Based on the analysis of product utilization according to the home lifestyle behavior of single-person households, a relationship model was presented, and IoT system configurations are designed based on the model. For design purposes, primary user residential behavior observation surveys, secondary surveys, and tertiary in-depth interviews identify residential space and daily behavior, product configuration, preference placement, and utilization families. In addition, a single-person household resident behavior-oriented object relationship model was constructed. Results Single-person households appear to use products in a small space by connecting them together in a complex and efficient manner. The analyzed behavior-things relationship model showed that the center of the IoT system was not AI speaker and smart phone, but ceiling light, indirect light, sitting table, and bed/sofa. Conclusions This study proposes a design for a home IoT system for single-person households in their 20s and 30s by organizing representative behaviors such as sleeping, cleaning, watching videos, home training, and going to work. Through this study, the direction of home IoT system design is proposed by analyzing and connecting everyday behaviors from user-centered ways to the perspective of lighting, electronics, and furniture.
