Introduction

The maritime industry, particularly the US Navy, faces unique challenges in underwater missions. The Divers Augmented Vision Display (DAVD), developed by the Office of Naval Research’s (ONR) Warfighter Performance Department in collaboration with Naval Sea Systems Command (NAVSEA) and Coda Octopus, is revolutionizing how divers operate in harsh underwater environments. This innovative system leverages augmented reality and real-time information sharing to enhance diver safety and effectiveness.

Understanding DAVD: A Game Changer for Underwater Missions

Key Components of DAVD

The DAVD system comprises several critical components:

• Heads-up display resembling virtual-reality glasses, adaptable to any Navy dive helmet.
• Specialized augmented-reality software for overlaying 3D sonar or virtual images onto the physical landscape.
• Laptops, cables, cameras, and lighting equipment.

Real-Time Information Sharing

DAVD enables real-time information sharing between divers and the surface team. This includes:

• Rate of ascent and descent.
• Time elapsed.
• Current and maximum depth.
• Remaining levels of breathing gas.

3D Sonar and Augmented Reality

One of the most innovative features of DAVD is its ability to create detailed 3D models of the dive site using sonar imagery. This allows divers to:

• Receive videos, technical manuals, images, messages, and other data.
• Navigate underwater more effectively.
• Maintain smooth communications with the surface team.

DAVD in Action: Success Stories

Maui Wildfires 2023

In the aftermath of the 2023 wildfires in Maui, Hawaii, Navy divers used DAVD to locate 26 boats that had sunk along a marina during the disaster.

Francis Scott Key Bridge Collapse 2024

DAVD’s 3D sonar systems assisted in salvage efforts after the March 2024 collapse of Baltimore’s Francis Scott Key Bridge.

USS Arizona Mapping

DAVD was instrumental in mapping the murky waters surrounding the sunken USS Arizona, helping the U.S. Pacific Fleet and the National Park Service inspect the condition of submerged, severely degraded construction moorings.

Future Enhancements for DAVD

Potential upgrades to DAVD could include:

• GPS for georeferencing.
• Physiological monitoring such as an eye-tracking device.
• Enabling DAVD to work without cables connecting to the surface.

Conclusion

The Divers Augmented Vision Display (DAVD) is a groundbreaking tool that enhances the safety and effectiveness of underwater missions in the maritime industry. By leveraging augmented reality and real-time information sharing, DAVD has proven its value in various naval and non-naval operations. As technology continues to advance, the future of underwater missions looks brighter and safer with innovations like DAVD.
