In 1997 I partecipate to a MIT MediaLab competition about wearable computing. My idea was to enhance a diver’s mask with A.R. / compass+gps etc. to provide orienteering informations and a most effective vision.
Today, It might be sense to update this old idea with a couple of submarine drones to get new cameras views, and some powerful LED on the diver gear to augment visibility (connected to the AR system of other divers) and support instant communication.
That’s could be a very exciting project and someone -on this planet- should do it. :) In the meantime, I found this nice concept on Yanko.
