When we hear the term "smart glasses" these days, we tend to focus more on the smart and less on the glasses. Researchers at Oxford University see things the other way around: putting the emphasis on glasses suggests a device that helps the visually impaired see the world, not augment it. This is the project Dr. Stephen Hicks of the Nullfield Department of Clinical Neurosciences at the University of Oxford has been working on: a wearable designed to give folks with partial vision a clearer view of their surroundings. It's not as flashy as Google Glass, but it has the potential to change lives. It's also being tested in the wild.
