Amazon's approach to smart glasses sounds pretty smart

We can all envision what augmented reality glasses might eventually look like: as thin and light as regular glasses, have all-day battery life and don't make you look like a complete cyborg dork. The problem is, those aren't technically feasible today, as Google Glass and others have proved.

What's new: That's what makes Amazon's reported approach so interesting. Rather than try to cram in all the tech that will go in the glasses of the future, it appears Amazon is focused on the technology that smart glasses can deliver today while still being light, working all day and not prohibitively expansive. And that means putting a big focus on its Alexa voice assistant as the star attraction.
