Regarding screens in glasses: where is the hold up? I've been thinking of prototyping something for the past few weeks (only thinking, hence my question).
However, as far as I can tell every major tech company still expects that problem to be solved and for them to be the Next Big Thing. I don't know why else they'd be putting so much money & PR into consumer AR efforts when it's niche at best, so long as you have to hold up a device to use it, unless they fully expect hardware development to come through in the nearish future and make AR glasses the next smartphone, in terms of becoming must-have and driving the next wave of human-computer interaction.
Problem was the only stories about it were about the “glass-holes” walking into bars with a camera on their face. I thought it was an interesting “intervention” style art piece that showed people still expected obscurity, if not privacy.
I've tried the glasses from North, which has been bought by Google a few years ago. The projection of the screen on the lens looks cool, but the glasses had no traction in the market and the company tried to charge me C$1100+ for a pair of prescription smart glasses.
