A method and device for triggering an event in a roving apparatus is disclosed, whereby an event is triggered when the calculated position of the roving apparatus falls within a predetermined area and at least one other triggering criteria specified for the event is met, such that if the calculated position of the roving apparatus is at a position where predetermined areas overlap, events from any of the overlapping predetermined areas may be triggered in accordance with the triggering criteria of those areas.
