Bionic Eyeglasses May Boost Impaired Vision 43

fangmcgee writes with this excerpt from a University of Oxford news release: "Technology developed for mobile phones and computer gaming – such as video cameras, position detectors, face recognition and tracking software, and depth sensors – is now readily and cheaply available. So Oxford researchers have been looking at ways that this technology can be combined into a normal-looking pair of glasses to help those who might have just a small area of vision left, have cloudy or blurry vision, or can’t process detailed images. ... The glasses have video cameras mounted at the corners to capture what the wearer is looking at, while a display of tiny lights embedded in the see-through lenses of the glasses feed back extra information about objects, people or obstacles in view. In between, a smartphone-type computer running in your pocket recognizes objects in the video image or tracks where a person is, driving the lights in the display in real time. The extra information the glasses display about their surroundings should allow people to navigate round a room, pick out the most relevant things and locate objects placed nearby."

    ...which are: 1) how do you get the signal from the cameras in the glasses to the processor and back to the display, and 2) how do you power them? It seems like you're going to need a fairly high bandwidth to carry visual information from the cameras and back up. Since these are glasses, you'll need to do this over a meter or more, and have to use an extremely flexible data pipe. Maybe some sort of flexure- or motion-powered charger could be used to top off the batteries. This (power) is the single greatest hurdle to overcome in the design of prosthetics.

With all the fancy scientists in the world, why can't they just once build a nuclear balm?
