11. A navigation system comprising: a control unit for: determining a travel context to detect a maneuver location traveling through a geographic region in real time by a location unit, generating a mental model for the travel context, the mental model being represented by a digital model, determining a landmark-determination zone dynamically and in real time based on a radius from the maneuver location within which a capturing sensor detects an object, determining a guidance landmark including at least one of a stationary landmark and a dynamic landmark based on the mental model, the landmark-determination zone, or a combination thereof for providing a navigation guidance, and a communication interface, coupled to the control unit, for transmitting the navigation guidance with the guidance landmark for presenting on a mobile electronic device.
