Monitoring movement of an entity in an environment

摘要

A method determining whether a person suffering dementia has left their flat unaccompanied is described. The method includes identifying an event indicating opening of the front door of the flat, determining whether flat was occupied by more than one person prior to the door opening, determining whether there is inactivity in the flat following the door opening and sending a notification to a communications terminal of a carer if the flat was occupied by only one person and if there is inactivity in the flat.
