Re: 3D crosswalk in Iceland helps slow down speeding motorists
#72These 3d perspective drawings are much less convincing in real life than they are in images, because in real life we have depth perception and our viewpoint is constantly moving. This only looks good from that exact viewpoint.
CAVE style VR suffers from the same problem if you don't want to use stereoscopic shutter glasses. You can track one user's head position and update the renderer's camera accordingly, but with multiple users you can't do that without shutter glasses. Even with shutter glasses, I'd think there must be some limit on how many users you could have at once without irritating flickering; with 3 users and six different pers…
Beyond approx. 30 ft., depth perception is useless in VR

#73Wonder what Tesla's vision-based automatic driving makes of this.

The article shows pictures of 5 different angles on that crosswalk, and they all seem to work.
Stereoptics ruin the illusion. Just like a 2d vs a 3d movie

> if every crosswalk in the world is replaced with this 3D version, we'll see a temporary boost in safety, but in the long run it may return to normal and in my opinion, our world will be uglier. Although the illusionary crosswalks shown in the article aren’t really ugly , and even advertisements, like the cute mascots and dazzling neons of Tokyo, can have a certain beauty to them, I agree that most garish attention-…

Tell that to almost anywhere in Europe: http://newworldeconomics.com/wp-content/uploads/2017/01/Shin...

#76I want the pattern for this. I suppose it's easy enough to make my own, but a pattern would be nice.
I live on a street where people drive too fast.

#77I wonder how well it would work in the dark.
even better, obviously

#78This is why self-driving cars need lidar (and maybe radar) as well as cameras.

Correction: when you have tall buildings they need to be spaced apart to avoid murkiness at street level.
In San Francisco financial district it gets dark around 4pm in summer when sunset is around 9pm. Imagine if those skyscrapers were as close together as the buildings in your picture.
Also I’m pretty sure that’s Japan. The filename says Tokyo.

#80There is an analogy here to the slippery-slope of attention-getting ads on the Internet. Once upon a time an ad was just a static (not even animated) banner of a certain size and shape. 468x60 was one of the earliest, IIRC. Advertisers invented new formats ("skyscrapers", "xl-leaderboards", "300x250", and so on), and also they got animated, and then they started expanding outside their areas, and so on; each new ad t…

Not just uglier, but less safe in my opinion. If people have returned to their normal driving habits (speeding over these 3d illusions) it means that at some level, they have reprogrammed their brains to ignore some 3d-like obstacles, because they may be fake. It works in case of the illusion, but I wonder if it would eventually impede their reaction time to other real, but similarly appearing obstacles.
