The incorporation of arising technology in maritime processes and equipment have been historically very important for the development of commercial navigation. Several types of equipment have been developed over the years to assist ship operators with their tasks. Generally, the incorporation of new technologies on maritime equipment are associated with an increase on the amount of information and alerts displayed to the corresponding users. Note that information from new equipment needs to be efficiently presented to avoid the introduction of unnecessary cognitive load. A potentially optimal option for the presentation of combined navigational information is the deployment of augmented-reality systems (AR). In such a system, virtual elements are rendered on top of the navigation scene to assist operators in their perception. In this context, the present work is a preliminary investigation towards the development of an AR system for navigational assistance. Particularly, foundations regarding AR systems are presented and a simple conceptual design for navigational assistance is proposed. Additionally, important components from the proposed conceptual design are exemplified with numerical implementations. Proposed methodologies are validated with experiments from videos of a ship navigating through a channel delimited by nautical buoys. Enhanced scenes combining pertinent virtual elements are shown on top of the navigation scene exemplifying potential assistance applications for this scenario. As there are still many challenges for the development of operational maritime tools with AR methods, the author also expects to contribute with the popularization of AR systems in maritime environments.
