But Glass doesn't project into the eye. It projects into a glass prism at the edge of a field of vision. The argument could be made that this still constitutes a distraction if it comes up, but if my phone is mounted in my car and lights up with a text, it's pretty easy for me to notice that it lights up but keep focused on the road and ignore it. I imagine a responsible Glass user could do the same.

Glass directly obstructs the view field, irregardless of where it projects. I agree with the citaion wholeheartedly. Regarding phone, see section b (11): http://www.dmv.ca.gov/pubs/vctop/d12/vc26708.htm http://www.dmv.ca.gov/pubs/vctop/d12/vc26708.htm

  Have you even used Glass? It doesn't obstruct my view any more than my prescription lenses.

    I have not, but looks like this guy has [1]. But I would also not rely on anecdotes, and would want them to test it out comprehensively before allowing it on road. If I am commanding a 1000 ton metal hurling with a speed of 110 kmph, its better safe than sorry. [1] - https://news.ycombinator.com/item?id=6640895 https://news.ycombinator.com/item?id=6640895

      Considering the legal weight limit (not including special permits) for commercial vehicles, e.g. 18-wheelers, on most US roads is 80,000 lb. (36.29 metric tons), it'd be quite surprising to see anyone in a 1000 ton (metric or short) vehicle, let alone traveling at a rate of 110 km/h.
      - iamshs 13y ago
        That 1000 ton was a very arbitrary spewed metric. The smallest of four wheelers is capable of much damage, which is what I was getting at.

  The display prism sits above your line of vision (and is transparent besides). It obstructs less than the typical sun shade on the wind shield, although the roof of the car vs. a convertible is probably a more accurate comparison. During normal usage the Glass blocks out a bit of the sky you never look at anyway, it doesn't sit in front of your eye.

      I have worn one. It does not impinge on your normal field of view. It's up and to the right of where you're normally looking and you have to make a conscious effort to direct your attention to it. In a car, as other people have said, the only thing it is likely to block your view of, is the inside of your car roof.

      It must depend on the user. I have worn them daily since end of April and only ever notice when they're not on my head. I'll feel a vibration in my pocket and try to check glass. The first few times you wear them you may notice them in your peripheral vision but your brain quickly tunes them out. There is no obstruction of my view. In my opinion, they are far safer to wear and use for the purpose of navigation than a phone or mounted GPS. They give me the necessary information quickly and don't require me to adjust my vision off the road.

  As someone who's worn Glass, and who regularly wears thick-rimmed corrective glasses, I have to say that the frames of my glasses are a larger obstruction than Glass. The screen on Glass actually rests outside of my normal field of view when wearing corrective glasses, it lies above where the lens would be, in an area where my vision is uncorrected and therefore useless for driving already. That's not a problem though because that area contains the sky and the roof of my car, two things mostly unimportant for driving. Should I be cited for driving because my corrective glasses don't allow me to see with perfect clarity the area where my windshield joins with the roof? I think not.

When I tried Glass, the display was always visible when active. At least it's physically possible to not look at your phone. The one defense I would give is that the Glass projection turns off quite quickly, presumably to save battery power. It's not an always on HUD.

It doesn't really matter. It's easily available distraction and people will end up looking on movies instead of the road all the time. It's like with TV in your car. It's not obstructing your view on the road, it's too easy to focus attention on it thus it's illegal to have one (unless it's switched off over some speed or w/e details various countries/states implement). >I imagine a responsible Glass user could do the same. The problem is many users won't be responsible. Good driver who doesn't use phone when driving is focused and well trained could responsibly break speed limit very often and still drive safer than 99% of people out there. Unfortunately it's impossible to fit the law to such cases so people who pay attention are hold to the same standards as texting-while-driving morons. Same with glass - banning it is better for everybody.

  > people will end up looking on movies instead of the road all the time Have you used Glass? It hardly seems likely people are going to use it for watching movies on while driving - the screen is really small and in one corner of your vision.
  - hvidgaard 13y ago
    The point is that is a possible distraction. You can only really thoroughly process 2-3 inputs per second. If something on Glass, no matter what, make you focus on it, you're down to 1-2 things, which might very well be the difference between a deadly accident and no accident. I'm sure a lot of users would be able to ignore Glass when needed, but the majority wouldn't and that's why they're making laws.
- seanc722 13y ago
  Responsible drivers, even those wearing glass, would only use it for driving related tasks, if use it at all. The irresponsible drivers, the ones who would watch movies, would do it whether it is legal or not. Same people who text and drive even though it is illegal.

That prism is part of the object, and the light coming from it enters your eye. You are not viewing a screen - your retina is, in effect, the screen. It's wholly inaccurate to say it doesn't project into the eye.
- Dylan16807 13y ago
  The prism is a mirror that lets you see the screen. But you're focusing entirely in the wrong part of this. The important thing is that it's a small display off in the corner, not blocking or overlapping what you're looking at. It's not aiming a light at your eye any more than a book would. http://www.catwig.com/google-glass-teardown/teardown/display-board-removed.jpg http://www.catwig.com/google-glass-teardown/teardown/display...

    The 'screen' is projected into your eye. The mirror is a lens that helps collimate the light for this purpose. The attentional split of the device is a different argument, but I was just correcting this error that there's 'nothing projected into the eye'. If your fundamentals are wrong, chances are you aren't aware of the caveats in this field.
