Lynx: Automatic Elderly Behavior Prediction in Home Telecare

Abstract EN

This paper introduces Lynx, an intelligent system for personal safety at home environments, oriented to elderly people living independently, which encompasses a decision support machine for automatic home risk prevention, tested in real-life environments to respond to real time situations.

The automatic system described in this paper prevents such risks by an advanced analytic methods supported by an expert knowledge system.

It is minimally intrusive, using plug-and-play sensors and machine learning algorithms to learn the elder’s daily activity taking into account even his health records.

If the system detects that something unusual happens (in a wide sense) or if something is wrong relative to the user’s health habits or medical recommendations, it sends at real-time alarm to the family, care center, or medical agents, without human intervention.

The system feeds on information from sensors deployed in the home and knowledge of subject physical activities, which can be collected by mobile applications and enriched by personalized health information from clinical reports encoded in the system.

The system usability and reliability have been tested in real-life conditions, with an accuracy larger than 81%.
