Abstract
Method and system for detecting abnormal situations of a person in a living place. One such method involves: receiving information provided by a sensor carried by the person, which information relates to at least one vital variable of the person, receiving information originating from a series of motion sensors provided at various locations in the living place, and comparing said information with predetermined rules involving timeouts established as a function of the location and of the period of the day, or else different timeouts depending on whether an anomaly has been detected at the level of the vital variable, or else according to a common process relaunched upon each arrival in a new location although no abnormal situation exists, and in response to the previous step, triggering or otherwise a signalling of abnormal situation. Application in particular to the telesurveillance of the elderly, with improved discrimination between normal, anomalous and alert situations.
