Speaking glasses will interpret the world for blind people

Ray Kurzweil : writer, futurist
Blind people will wear special glasses that interpret the real world for them through speech. Sighted people also will use these glasses to amplify their own abilities. Retinal and neural implants will also exist, but will be in limited use because they will be less useful.
