My otherwise ridiculously healthy dad was diagnosed with glaucoma a while back, and though it now appears to be under control thanks to the right prescription meds, his vision isn't as good as it used to be. Specifically, the contrast and brightness of what he sees with that eye has been reduced.
An avid user photographer, my dad posed a fascinating solution to this problem. What if he hooked up a Looxcie-style video camera near his left eye, then fed the resulting video through an auto-contrast filter, which would display on a small screen inside a pair of glasses. It might look weird, but it'd be a real-life use of augmented reality that's actually useful. In rough visual terms, this is what the problem is and what the solution would do:
To me, the strange thing is that this sounds possible, even plausible. Then again, I don't know how technically challenging it is to provide that kind of real-time video correction. Where are the sticking points? My dad and I would love your help sketching out how this contraption could work -- and then building it.
Searching around for information on how difficult this task might be, I wasn't able to find much. Much of the discussion around augmented reality vision focuses on contact lenses, I suppose because they are futuristic and sexy. But my dad isn't looking for anything that crazy. He just wants a pair of glasses with an auto-contrasting screen for the left eye.
