Abstract
This paper presents a location aware alarm system developed to give each person greater and safer mobility by automatically detecting risk situations. Location awareness has been possible thanks to an indoors positioning system (IPS) based on Bluetooth and ultrasounds, developed by the authors. The IPS is able to give accuracies of several centimetres, using a reduced infrastructure (6 fixed beacons every 100 m2). The alarm system has been implemented in several stances of a special education school. Preliminary evaluation results show its reliability and usability.
