Recent demographic analyzes show that the average life span of the population is lengthening. This will lead to an increase in users in health facilities with repercussions on the quality of services.
Ambient Assisted Living (AAL) is a European project for the development of new non-invasive technologies allowing the monitoring of the daily activities of the elderly in the home environment, guaranteeing a prolonged independent lifestyle.
This work aims to design and develop a predictive model based on the measurements provided by four sensors installed on the subjects.
