I wonder if it can read computer screens. I have a friend who is almost blind, and a huge problem for him is touch screens, and displays for things like train schedules.

Ups! Thanks.

All's cool, Heavenfall. If your friend uses some magnification on the screen, it'll probably help the device, although I'm not 100% sure of that.

Well, that's the problem. If it was his screen at home there are all kinds of tools available. But for example if he wants to check in via machine at the airport, he can't really see what's on the screen. And most Swedish stores have touch-displays for if you want to buy certain items like condoms/non-recipe medicine (you use the touch-display, get a receipt, then go to a vending machine with the receipt outside the store). Those are also impossible to use for him. And I already mentioned  displays at say the airport or train station with schedules for trains - often placed high up. Sounds like this could really help him out.

But what if you can't see this?

There's one in every crowd. 

This might seem like something wonderful and i like the idea what i don't like is that there his to little info on it. 
Attached to a portable computer so like a cell phone device is it connected to a server where that data can be processed?
Something similar was posted by you as well DOC some sort of goggles that acted like a phone- don’t remember.
Anyway while i like the idea i hope it’s not giving feedback about your behaviour to some server  

Each unit is individual, as far as I know. These aren't "surveillance" devices, Rolo, they're for the vision impaired, folks not usually employed in spying. If a central server is used, they haven't mentioned that.

Not at all like Google Glass or the other post.
