No, that's 2D, not 3D. It knows the direction your eyes are facing, but not how far away they are, which is needed to project an overlay correctly.
Google glasses can do it because you're always the same distance from the screen, but when driving you aren't, unless someone straps your head to the headrest.
So you need 3D head monitoring, not just 2D. And that's not here yet.

Perform this thought experiment. You are in a large lecture hall. There is a computer projector displaying a circle on the screen at the front of the room. The projector electronics have taken the angles into account and distorted the incoming video signal so that the displayed image is a circle on the screen. Now move about the room so your perspective of the screen changes. The image on your retina will change based on your angle to the screen, but your brain will still see a circle.

Counter-example: Walk along a school road, and look for the SCHOOL marking in the street. From the side, it's so distorted that it's very hard to make out what it says.

I'm piloting over a tonne of metal moving at speeds capable of inflicting instantaneous death upon anything in my way; don't fucking distract me by putting on a pretty light show on the road ahead!

Indeed. And this includes strobo lights on bicycles, which are banned in some more civilized countries precisely because they cause accidents for others than the selfish bastard using them for their own protection, fuck everybody else.

Cooperate, and don't distract people who try to control heavy objects at high speed.

The correct way to do this is with a heads-up display.

That works great if it's calibrated to your head position, and you don't move your head a lot. Not so much for Wayne and Garth.
Head tracking and a fast computer might help, once it not only tracks a 2D head position, but also distance from the windshield.

The problem is perspective. The road is flat, so what's projected on it will not appear as the same shape for someone looking on it from elsewhere.

Also, roads are seldom ballroom floor flat. Which paint can overcome, but a very shallow angle light can't. Even a very small hump in front of the target, small enough to not even notice when driving over it, can block the light.

Only 92 million Americans are out of work. A number that haven't changed in four or five years.

Currently as of November 2016, 59.7 of the adult population is employed. That means that out of the 245.3 million adult Americans (also per November 2016), 98 million are unemployed.
But that figure isn't too useful alone. It doesn't reflect either those who live on their fortunes (including pensioners), nor does it account for those who are underemployed.

And as for the number not changing, look at the statistics. There's a small but significant and near linear climb in employment rates for the last five years. It's not big enough to make up for the toll the 2009-10 recession took, but it's certainly pointing upwards.

Comment Re:Hey look the flow rate is a little high. (Score 1) 178

But that's the problem - you can decide who you sync with, but you cannot decide who others sync with.
A time discrepancy is a problem in either case.

The most obvious solution is that the bourses should provide time synchronization, and that everyone else sync to their time, right or wrong.

I suspect very few here will any any sort of sympathy for people who do low latency stock trading.

That's short-sighted thinking. Low latency traders exist, whether we like them or not[*], and it does not affect just the traders, but the stocks they trade, the companies, and other stock holders not involved in low latency trading. Their ability to do harm to others is affected when the playing field shifts, giving advantages to some. They're at war with each other, and the playing field being level helps maintain status quo, and prevent stocks from crashing or soaring when they shouldn't.

[*]: I too think they're scum. I'd like to see all stock trades have a delay of one business day.
