You mean this glass reads for the blind? What... !? Now that is real invention and innovation. It is one of the best that I have seen so far. Having a device like this that will totally negate the disability of people is certainly not just a game-changer but also a turning point for the disabled person's life. Imagine a blind being able to read through this glass.
I hope the glass will be enhanced further to recognize not just characters but also 2D objects, at least. For now, this is simply amazing!
