Abstract

A device moving in a space determines one or more zones around it, wherein the one or more zones are linked to the device and move together with the device through the space. The device detects if a border of a first of the one or more zones starts to intersect or stops to intersect with a border of an area inside the space. If the detecting is affirmative, the device transmits information related to the intersection. An apparatus receives this information from the device and adapts a status value of the area in dependence of the received information.
