A Smart System for Elderly Care using IoT and Mobile Technologies

Abstract

Population aging is becoming a pressing issue for society. The number of elderly people, those aged 60 years and over, is increasing dramatically in many countries. A great number of elderly people stay alone at home while young people in their family go out to work. This paper presents a smart system designed and developed for elderly care using IoT and mobile technologies. The features of the system include acoustic-based and accelerometer-based fall detection, real-time remote video monitoring on mobile devices, voice commands and heart rate monitoring. The evaluation matrix shows that the accuracy, precision and recall of the accelerometer-based approach were 93.3%, 92.6% and 94.3%, respectively, while the acoustic-based approach achieved 78.6%, 76.9% and 80.6%, respectively.
