Abstract: Various embodiments of the present disclosure provide an apparatus and method for determining the target area associated with the vessel. The apparatus includes a motion data receiver and processing circuitry. The motion data receiver is configured to determine a motion-related data of a vessel. The processing circuitry is communicably coupled to the motion data receiver. Further, the processing circuitry is configured to cause the apparatus to determine a change in a moving direction of the vessel based at least on the motion-related data of the vessel. Furthermore, the processing circuitry is configured to adaptively determine a target area associated with the vessel based on the change in the moving direction of the vessel, thereby enabling the apparatus to determine the target area based on the change in the moving direction of the vessel.

Abstract: A route setting device is provided, which may include a display controller, a user interface device, a waypoint detecting module, and a route setting module. The display controller having a display screen may display map data on the display screen. The user interface device may accept a route input operation using the display screen where the map data is displayed. Processing circuitry may detect a waypoint of a ship in the map data based on a trace of the route input operation in the map data. The processing circuitry may set a route of the ship based on the waypoint.
