In France, people aged over 60 represent 20% of the population (more than 80 years: 3.4%). Because of their age, they are fragile, frail and isolated, so it is necessary to implement systems that overcome these disabilities. Today, there are about 800,000 people dependent in France (1.2 million in 2040). In this context, techniques for locating the person can limit the risk of falls and assist the person by observing his life scenarios. These techniques take into account the project life of the elderly by including particular needs and consequences of falls. Various technologies exist for localization. The impact of these technologies is illustrated by several technical solutions and in particular by the example of smart floor. Falls are the leading cause of accidental death among for people over 65. 8 500 deaths and 91 000 hospitalizations per year are related to fractures of the femur and legs, that occur on average one out of three (27% for 65-70 years and 44% for over 90 years). Falls also create social implications such as isolation or dependency. The localization of a person in his house can help to ensure a level of security and well-being leading to a vital home maintenance. Indoor localization solutions today use various techniques (ultrasound, RFID technologies, optical or RF triangulation methods). Geographical detections solutions using the floor itself consist in placing a thin layer of detectors under resilient flooring. The detectors are connected to an external electronic interface managed by specific software which allows to launch real-time alert in case of fall of the person. A major advantage is that the process is non intrusive because not visible to the person. Thus, it may be better accepted by the elderly. Through its electronics, the floor can be interfaced to automatic or computer equipments. Connected to an intelligent system, the floor can also easily be used to track activity of the person. The overall system connected to the Internet can handle emergency or alarm. It may also assist the individual in his daily tasks, controlling the automatic start of some appliances or multimedia (eg TV), or automatically opening certain doors. The system having the floor sensor can also easily and intelligently manage the lighting or the heating mode for comfort in occupied rooms and in economy mode in the non-occupied rooms. Different scenarios can then more easily be created for optimal management of the housing.
