> The first-gen North Focals glasses won't work after July 31, 2020, but North is issuing refunds to people who bought the smartglasses
At least they are giving out refunds, unlike other companies that have shutdown, but still.
Things like this is why I am a firm member of the selfhosted club

That's pretty much what the normal experience is for buying prescription glasses.
You try on the frame to see if it is comfortable, but you can't try out the prescription in the frame until a week after you have ordered them.
They were alright. The frames were reminiscent of big hipster frames, which I don't like, but they weren't outrageous. The visible area was small and neat, but I couldn't see any use for it. Probably the size of an apple watch, just floating in the corner of your right eye. The demo was walking directions and talking to alexa. They didn't sell because they weren't very useful and were very expensive.
Maybe Google's current strategy is the correct one - keep developing the tech for well-scoped, very niche applications until some day the tech might be good enough for general purpose applications. I think that day is still far away.
I think a big issue with wearable computers will be input devices. I have trained with the 1-handed chorded keyboards, such as the twiddler, and am up to 30 wpm, but its not easy and I don't think people will be willing to make that kind of adjustment. Even so, you still have to then constantly carry the input device around and have it in your hand. A "hands free" input device like the ring, or an improved Myo style band, will still be needed for any wearable that is used in a non-private setting, where voice commands are not ideal (unless its a throat mic).

The interface is roughly 6 lines of white on transparent text/menus/icons, with some "apps" occasionally being more graphical and having larger graphics/arrows. The display is basically a bunch of low power lasers being projected onto a weird thing embedded in the glass of the right lens and getting reflected into your eye. If alignment was wrong it couldn't do anything. It felt more like those vector CRT displays like from an old arcade game, where instead of pixels of varying intensity in a grid there is an electron beam just drawing lines and simple shapes.
There was definitely no ability to project a screen. It was not like google glass at all.
Platform-wise, it was more like an imaginary gen-0.5 smartwatch that was locked into a handful of baked in apps and notifications. It had to be tethered to your phone to work. It could only integrate with select apps and services: Spotify for music, Alexa for a voice assistant, gcal for calendar. I'm probably missing some.
It had some morning glance sort of thing that showed you your commute and the weather and maybe some news?
It had it's own walking navigation system that worked... okay. Granted I tried that out pretty shortly after that feature launched, and only used in Dublin when I was on a trip where I would actually be walking a fair bit. It never inspired confidence that it would notify me properly of a turn, and I tend to not really need directions shown to me all the time anyways, so I stopped bothering after using it twice.
Notifications was about the only thing I got out of it when I was using it, and it was not the best experience. The time between knowing I got a notification and it showing me was long enough that I never got over the muscle memory of either pulling out my phone or looking at my pebble (if I was wearing it) when I felt the vibrarion from either.
That brings me to the hardest part for me, the lack of confidence in the projection. When I pressed on the ring controller to activate it, or heard a sound indicating something should be on screen, I couldn't be sure that it wasn't just being slow or if it was somehow misaligned. It got misaligned often, and when it's not in just the right alignment with your eye the display is not visible. I eventually got some of those silicone things you put on stems to hold glasses on your face properly and even then they could still get out of alignment.
EDIT: totally forgot, a cool part was how you contorlled it, with a ring that had a little 5way joystick on it. This would have been cool if it was more responsive, but it suffered from the general interface sluggishness that did not inspire confidence.
