Alright, what other consumer products like Google Glass have been released?

This is very much specialised stuff however - would you ever see your average consumer walk around in public with it? No - because these are ski goggles not normal glasses.

I think blhack is playing semantics with 'consumer'. They are skiwear consumers that bought them. I think it was pretty clear that you meant something like widespread public use.

I'm not sure whether it's similar enough, but the "Private Eye", a wearable, monocular heads-up display, had a bit of niche success when it was introduced in 1989. Here's a contemporary blurb from Popular Science: http://www.popsci.com/archive-viewer?id=dwEAAAAAMBAJ&pg=...

Interesting, but fundamentally different.

Google Glass = head-mounted display + camera + access to the cloud

The Private Eye was just the first. It's like comparing an exercise bike to an actual ride-around-outdoors bicycle.

Plenty of products exist. Google Glass is just a very very good iteration of existing tech.
