Abstract

This study aims to identify major research topics in sensor-based technologies used in care environments and examine their trends over time. The analysis included 611 English-language articles collected from the Web of Science Core Collection. Annual publication trends and keyword frequencies were examined, followed by topic modeling and keyword co-occurrence network analysis using degree, closeness, and betweenness centrality. Research in this field has increased markedly since the 2010s, with more than half of the publications appearing in the 2020s. Five major research topics were identified: fall detection in ambient assisted living (AAL) environments; gait and rehabilitation interventions for older adults with frailty; fall risk prediction and performance validation; sleep assessment and intervention for people with dementia; and environmental sensors and human activity recognition in AAL environments. Fall detection remained the dominant topic, although its relative proportion decreased over time, while research on sleep assessment and intervention for people with dementia increased. The network analysis showed that intervention, daily life, group, model, and lifewere among the most central keywords across the three centrality measures, whereas specific sensor devices and technologies were not highly central. These findings suggest that research in this field is organized around the measurement and monitoring of older adults’ daily lives and conditions, risk detection and prediction, and the application of sensor-based technologies to intervention and care, rather than around specific sensor types. This study provides an overview of the evolving research trends and major conceptual connections in sensor-based technology research in care environments.
