Augmented Reality Lights for Compromised Visibility Navigation

This paper considers the feasibility of using augmented reality (AR) as a tool for enhancing visualization in maritime operations to avoid collision in different environmental conditions. According to the International Maritime Organization (IMO 2010), 90% of maritime accidents due to collisions at sea are caused in part by human error. This study investigates the new technology (AR) used to superimpose holographic images onto the real world; now reaching a state of readiness for commercial application. This paper demonstrates the competence of AR technology to serve as a maritime navigational aid. The research explores the viability of improving navigational safety in low visibility by projecting holograms of real-world objects in the same geo-location as the real object to make them “visible”. The paper presents the logical deconstruction of the technical problems and identified solutions, together with results of experiments used to validate the concept and technology readiness for real word maritime application. The paper presents a verified demonstrator; a proposed holographic bridge interface with an innovative way of presenting information using AR technology. Furthermore, it identifies that new technologies offer the opportunity for enhanced operator performances, with the expectation being that this should lead to reduce risk to persons, property, and the environment.

Laser-Based Aid Systems for Berthing and Docking

The berthing of an ultra large ship is always a difficult issue and becomes yet more complex when vessels must be handled in restricted manoeuvring areas of limited depth, exposed to a forceful crosswind, or manoeuvring in a strong current, or all three. The final approaching manoeuvre and precise positioning is particularly demanding at container terminals where many STS cranes are located along the quay, seriously limiting margin for error in the process of mooring a ship, especially when the cranes are located nearby a bridge wing or at the very edge of the pier. In order to avoid collisions, the final manoeuvre (side-push) must be fully controlled; the ship’s orientation must be parallel with the quay while maintaining the minimum lateral approaching velocity without significantly shifting the vessel longitudinally. The mooring of a Ro-Ro vessel is occasionally even more challenging: a precise docking manoeuvre is normally executed without any towing assistance. In this paper low cost laser-based berthing and docking systems developed for the ports of Koper and Swinousce are presented and several berthing manoeuvres are analysed and compared with the most commonly used GNSS-based navigational aid system portable pilot units (PPU).

Exploring human behavior with Grand Theft Auto V: A study of assisted cognition in wayfinding

The rise of virtual reality has overcome many of the methodological challenges faced by researchers studying spatial navigation. Yet, the difficulty in developing life-like virtual settings still remains a substantial barrier to most studies when fidelity to the real world has to be achieved in order to ensure some psychological validity of the results. Moreover, the variety of the settings results in standardization issues across studies. Our argument is that widely available video games could represent a worthwhile alternative to laboratory-made virtual environments, while providing a satisfactory methodological quality. This study assessed a prototype of landmark-based navigational aid by administering wayfinding tasks in the video game Grand Theft Auto V. Our results provide evidence that this video game offers a transparent and adaptable way to investigate cognitive processes with high experimental control and psychological validity. Recommendations towards the use of video game-based methodologies for future research are discussed.

Human bodysuit with Color Sensing for the Visually Impaired

In this paper, a navigational aid for blind people is developed as a suite with the handwear module, which makes use of ARM LPC 2148 microcontroller board with ultrasonic serial ASCII sensors and tappers for collision avoidance and a provision for primary-colored objects detection. The user is alerted with tapping mechanism and synthetic voice feedback to guide the navigation. The user is also provided with buttons for switching on the Left and Right-hand wear sensors and sensing primary colors. The user can also turn on and off the GPS and GSM modules, which gives the location of the user through a message to any preloaded number for assisting. Thus the proposed handware module helps the blind people to navigate outdoor and can differentiate primary colored objects that helps user in segregating daily household objects, appliance, clothes, etc. The paper also gives an idea of possible additional provisions to the jacket are explored.

Follow the Leader

Two studies investigated the concept of following a lead vehicle as a navigational aid. The first video-based study (n=34) considered how drivers might use a real-world lead vehicle as a navigational aid, whist the second simulator-based study (n=22) explored how an Augmented Reality (AR) virtual car, presented on a head-up display (HUD), may aid navigation around a complex junction. Study 1 indicated that a lead vehicle is most valued as a navigation aid just before/during a required maneuver. During the second study the dynamic virtual car (which behaved like a real vehicle) resulted in greater confidence and lower workload than a static virtual car that “waits” at the correct junction exit, but resulted in more gaze concentration. It is concluded that a virtual car may be a valuable element of a navigation system, in combination with other forms of information, to completely fulfil all a driver's navigational task requirements.

Information Technology in Navigation: Problems in Legal Implementation and Liability

E-navigation poses significant challenges for shipping. The analysis of the legal norms in the International Regulations for Preventing Collisions at Sea (COLREGS) and court decisions supports the use of information technology on the bridge for the purpose of improving navigational safety. However, the current regulatory and standardisation requirements hamper the introduction of new information streams in navigational systems and remove the incentives for investment in navigation technology. The liability arising from navigational failures will remain on the employer of the crew irrespective of how the additional navigational information is provided to the navigational systems. The shipowner's liability may depend on the way information streams are provided to the ship only within the context of the Civil Liability Convention (CLC) 1992 and other similar pollution conventions where the characterisation of the navigational system as a navigational aid or an aid to navigation may decide the issue of liability. Research on the legal background of these terms underlines the need for a clear distinction between the two terms to be made. An interpretation is proposed which ensures that the CLC liability exception operates in accordance with the underlying legal requirements.
