Physical activity measurement and indoor location for the assessment of daily routines in older adults

Abstract

Este trabajo presenta una propuesta para la monitorización de adultos mayores con el fin de inferir las actividades de la vida diaria (ADLs), e identificar desviaciones en sus rutinas que podrían necesitar alguna clase de intervención. Esta monitorización se consigue analizando el tiempo que pasan en cada habitación de su lugar de residencia, el cual puede ser estimado con balizas basadas en tecnología BLE (Bluetooth Low Energy). Las balizas receptoras de BLE desplegadas en el entorno detectan la señal del dispositivo emisor que porta el usuario. La localización de la persona se realiza a través de algunos métodos de fingerprinting, procesando la intensidad de la señal recibida.

This paper presents a proposal for monitoring older adults in order to infer activities of daily living (ADLs), and identify deviations in their routines that might need some kind of intervention. This monitoring is achieved by analysing the time spent in each room of their place of residence, which can be estimated with beacons based on BLE (Bluetooth Low Energy) technology. The BLE receiving beacons deployed in the environment detect the signal of the transmitting device carried by the user. The location of the person is done through some fingerprinting methods by processing the received signal strength.
