Augmented actuality involves deep-sea divers, due to the US Navy’s Workplace of Naval Analysis (ONR) and Coda Octopus’s Divers Augmented Imaginative and prescient Show (DAVD) system. The setup turns any commonplace diving laborious helmet right into a digital info heart.
If you happen to’ve ever finished any informal vacation scuba diving in locations just like the Bahamas, or watched undersea documentaries, it is easy to get the impression that being underwater is all clear water, white sand, and coral reefs populated by charming tropical fish.
Nonetheless, as somebody who has finished numerous work underwater, I can attest to the truth that it is often a lot totally different and nowhere close to as nice. It is so laborious to work whereas diving, that duties which take minutes topside want hours underwater. What’s extra, the ocean has a nasty behavior of being silty or muddy to the purpose the place you’ll be able to’t see quite a lot of inches in entrance of you – the one warning that you’ve got simply scraped via a patch of fireside coral is when the stinging cloud hits you within the face.
DAVD
For deep-diving mixed-gas divers, it’s miles worse. Routinely diving beneath 130 ft (40 m), the divers are all the time in pitch darkness, counting on work and helmet lights, and they’re tethered to the floor by difficult umbilical cords offering them with communications in addition to feeding them a mix of helium and oxygen. As a result of helium shortly carries away warmth, heat water can also be fed into the divers’ fits, in any other case they might freeze to demise.
Add within the aforementioned mud, silt, and a heavy dose of plankton, and it is no marvel that these divers command a really excessive pay grade.
To make the diver’s life simpler, ONR and Coda Octopus have give you DAVD. Under development since 2016, DAVD is a step up from the video cameras that divers usually carry. The issue with these cameras is that they ship pictures to the supervisor on the floor, however to not the diver, leaving the supervisor with the unenviable process of describing to the diver what is correct in entrance of him.

Worse, video cameras are very restricted in what info they’ll convey. DAVD will get round that limitation with software program that enhances each video and audio, cleansing them up whereas cancelling audio noise and permitting the supervisor to supply video with augmented actuality annotations again to the diver. Readouts are supplied by a pair of glasses mounted contained in the helmet or on the helmet’s faceplate.
Nonetheless, DAVD’s capabilities go nicely past that. It may present the diver with readouts of depth, stress, dive timers, fuel reserve ranges, compass headings, 3D sonar maps and 3D fashions, navigation directions together with waypoints, pictures, insert video feeds, and technical manuals.
In response to ONR, there are at the moment about 15 variants of DAVD. The system has been utilized in quite a few operations, together with restoration efforts within the wake of the 2023 Maui wildfires, the Francis Scott Key Bridge collapse, and inspection of the USS Arizona conflict memorial at Pearl Harbor, Hawaii.
