Determining entry into or exit from a place while a tracking device is in the place

摘要

A computer-implemented method comprises: receiving (100) first information indicative of a tracking device being located in a particular place, for example by detecting that the tracking device is connected to a charging station for charging; receiving (102) second information, from a passive detecting means, indicative of the user of the tracking device leaving said place, for example based on sounds that the user has made in leaving; (104) determining, based on the first and second information, that a user of the tracking device leaves said place while the tracking device remains in said place; further to said determining, causing (106) at least one separation related action to be performed, for example sending a message to a remote server (14).
