When I get this message

Unfortunately, getUserMedia is not supported in your browser. Try downloading Opera 12 or another browser that supports getUserMedia.

in Camino, I'll try the page again in Safari-- auto-updated so it's always current-- if it sounds interesting.

If I then get the same message in Safari...

Screw 'em.

Worked fine in Chrome for me.

Okay... that's pretty amazing.

As is, from a usability/readability point of view, it's awful. But as a proof of concept, it is one of those "holy #*$!, this must be the 21st century" type of moments.

I'm not sure if this is a poor implementation or a poor application, but I can imagine an interface where I as the user tell my browser stylesheet how large fonts should be at a few different breakpoint distances and this just makes sure I never have to use CTRL+ again.

Probably a little of both, but I think it's really cool. I could see it reducing eye strain over the course of a day while you're working at a computer. Right now you're always moving around but the text size stays static causing you to squint.

Wouldn't it be cool if it took your vision into account as well and adjusted focus (or whatever; I'm not an eye doctor!).

(or whatever; I'm not an eye doctor!).

Your "enthusiasm" is misplaced :)

causing you to squint.

"squint" does not mean what you think it means..
thus..again..

Your "enthusiasm" is misplaced :)

I'm not an eye doctor!

Neither am I..But..amongst others..I also have a degree in what could be loosely described as "optics, sight and perception"..and a few others which touch more than tangentially on the wider fields of sight and visual perception..in humans and other species..

"squint" has a very definite meaning..

Best advice for anyone using computers and or other electronic screen devices..? don't..

Doing so is bad for your eyes..

Insufficient variety ( changes ) in the distance at which you are focusing during any given period ( every 5 minutes for example ) does not exercise the tiny muscles in your eyes sufficiently..your eyes did not evolve to spend so much time per 5 minute period ( or per hour / 24 hour period ) focused upon a flat surface at 30 cms to 70 cms in front of them..

Get up..Go outside..walk about for at least 5 minutes..looking at the world around you ( both near and far ) not at your phone or tablet ..do this very 30 minutes or so ..certainly every hour..

Or your vision will suffer and degrade..

If you do not do so ..

By the time you are aware of the truth of this advice..it will be too late .. your vision will already be affected.."gimmicks" not withstanding..
