> Most people already spend to much time staring at their phones Compared to what? This sounds like something a closed minded person would say. My grandmother says "I cant believe you stare at screens all day". Today, people my age don't even question it. The phones years ago were too old, and the software was pretty unusable, but now the hardware is significantly better, you can push a 100,000 poly model in realtime…

I see it as spreading the conversation to more people than are around the table. Plenty of conversation appears to be happening too. But that could be a cultural thing.

Any idea how it works behind the scenes? From some of the details, I assume the mapping is gps + sensors + something like Photosynth or this: https://www.popsci.com/gear-amp-gadgets/article/2009-09/buil...

pretty much that.

They have gone round and taken a video of every street in a certain area, unpacked it, extracted salient points, reconstruct those points to get a 3d map.

From that, given any 2d image you should be able to extract a bunch of "salient points" or known points, which from their relationship to each other can tell where the camera is, and what direction its pointing.

The two hard parts are 1) collecting the data 2) searching the data in reasonable amount of time

you can see it here in their demo

https://youtu.be/tXwVg2S9wuY?t=60

the "salient points" are called keypoints and their feature vectors are called descriptors

https://en.wikipedia.org/wiki/Scale-invariant_feature_transf...

you are correct that the challenge is collecting and indexing/retrieving but there have been techniques that do this for a while

https://web.eecs.umich.edu/~michjc/papers/p144-park.pdf

(they even tested against SIFT descriptors)

the real thing that i'm puzzled by with blue vision is how they're registering against ARKit descriptors (if they are at all) since apple doesn't expose them in the ARKit api (only the point cloud itself). ARCore used to expose them (https://stackoverflow.com/a/29012790) but i don't think it does anymore. they must be doing the registration because they only support devices that are running ARKit/ARCore (and without it they would just have built a SLAM system - albeit backed by an "arcloud" - that sits beside ARKit/ARCore and would most likely be inferior).

I don't go to bars, I'm too busy staring at screens ;) . haha! This is the app I was talking about: http://www.bbc.co.uk/mediacentre/latestnews/2018/civilisatio... . give it a try, it's cool!

But you know... you don't bring your computer to drink with friends. ;-) BBC app is awesome it could be way more awesome when using a smart glasses but we don't have them yet. I'm waiting for that day... :)

I kind of use that “would I pull out my laptop” question as a guide to mobile phone politeness. In any social context, if it would be rude to pull out a laptop and start typing, then it is also rude to pull out your phone and use it. Rule of thumb, there may be exceptions.

I totally don't get how this could be useful without smart glasses. Most people already spend to much time staring at their phones and with this crap will be even worst. Such solutions were already years ago and were not adopted because phones were too weak and software unusable. Nothing has changed except that we have better phones and rest is still a crap. I just wait for someone to fall under the car collecting go…

"Running all over the city" sounds like a rather good thing wrt health.

And why would anyone be bothered by others seeing flying emojis if the chose to?

I'm not bothered by it just for me it's silly and pointless use of great technology.

Yes, you are, because you seem to put everything under the common label of "staring at screens" :). You look around the bar, and see lots of people staring at screens. Were you to look closer, peek over everyone's shoulder, you'd see that the group over that table is skimming the project document they met to talk about. That couple over there just took out their phones to skim the news, the first moment they had duri…

> Yes, you are, because you seem to put everything under the common label of "staring at screens" :).

I'm not and don't exaggerate with this. I don't mind if someone commute for a an hour and a half to work and reads a book, skim the news news or prepare for work meeting. This is not the point here.

It just hurts me as I see people who evidently met to spend time together and for 40 minutes did not exchange words but they scroll through instagram or facebook all the time and I am a witness to such situations constantly.

But this is not a thread about it, anyway I think that the AR deserves better times and much more convenient equipment than the phone in hand.
