Do you mean the accelerometer values drifted over time (i.e. the direction of gravity shifted on a stable accelerometer) or do you mean the value when doubly integrated drifted?
Right: the doubly integrated values shifted while the sensor didn't move.

How about a HUD that projects a map onto a firefighter's SCBA facepice? That would be absolutely incredible... Firefighters die every year because they get disoriented and lost in zero-visibility conditions. Even if it didn't have a pre-generated map of the structure loaded... it could build a map as it went, and at least be able to provide a 'retrace my steps' view.
This just adds a depth camera to the phone and uses it and the visible light camera to map the space and orient the device. If a human is disoriented in a no-visibility situation due to smoke, the cameras will not likely be able to orient them either, except maybe something like a power outage, where visible light is unavailable but the depth camera can still function.
It could also be networked with other devices, such that all of the routes mapped could be composited and help in the identification of alternative routes should one become blocked.

It doesn't mean it. It just means that if enough people think the same way, the world is doomed. Or, if not doomed, it's not getting any better in areas that matter. (People laugh at words like "doomed", assuming everything will be as it was when they were growing up. For some lucky ones that's true. For others the worse happens, like a financial collapse or a world war, and then they "knew it all along it was going…

People paid a trillion in the US alone, out of their pockets, to ameliorate it (plus close to another trillion they lented to Detroit). And tons of middle/working class jobs are not coming back in the foreseeable future.
And that's the US. For some European economies it is even worse -- they got from 30% unemployment to double the suicide rates in 3-4 years time.

I suppose the good news is that 3D point cloud data in context of a public setting wouldn't be much more invasive than the already-pervasive video surveillance we have today. The bad news is as you say: having mapping data of your private residence siphoned off by third parties, be it government or private industry. I would say I'm as excited as I am worried about the potential for this technology. That said, I think…
Did HN react to the Kinect or Kinect 2 this way? It seems like there's a lot of burden put on Google to not do stuff that could be creepy even though that's all they do.

This. I hadn't seen this app before and as I soon as I saw it I clicked "Install". Lovely stuff. Look forward to putting it to the test tomorrow and the foreseeable future. As an aside, do you expect to monetize this in someway, or are you just doing it for the good of man?
Thanks to both of you, I hope you find it useful and let me know if you run into issues. I'm planning to monetize and I have a few ideas, hopefully one of them works out!
Sorry, today is clearly Pun Day.

What "scare story"? Financial collapse already happened in 2008. People paid a trillion in the US alone, out of their pockets, to ameliorate it (plus close to another trillion they lented to Detroit). And tons of middle/working class jobs are not coming back in the foreseeable future. And that's the US.

> updating it’s position and orientation in real-time ITS NOT IT'S
It's not "it's"! It's "its".
This is essentially putting a Kinect in your phone and hooking it up with hopefully high-level APIs. It may take 2-3 years to make it into regular phones, but when it does it will be huge. Apple's acquisition of PrimeSense (the makers of the 1st gen Kinect) means they're also working on this. To give you a real-world example: when I started BarSsense ( http://www.barsense.com ) the core problem was tracking the path…
I think the end game of this technology can help people without a coach learn to lift. From what I've read about how people learn, immediate feedback is extremely important, as in within a couple of seconds. I'd love it if this took bar path and velocity information, and put it into a machine learning system. The app could watch you in real time and immediately tell you whether it was a good lift or what was wrong with it. Lift your butt up faster, or lift the bar faster, slower or whatever. I think you'd need to sit down with a couple good coaches and have them classify what's wrong or right with several hundred lifts to get your training dataset—but I would love to pay for this product.

> Good god I am so sick of reading comments like this. This view of the world is just lazy. I think your view of the world is the lazier of the two--you're basically saying "let's not worry about the negative implications of the things we create as long as our intentions are good". > Who cares? If you don't like these services, don't use them. Nobody is forcing you to use this device . . . If you don't like modernity…
I think the grandparent's point is to focus on things that are actionable . If you are worried about the information Google collects on you and so choose not to use Google products - fine, that's your right. But if you're worried about the information Google collects on you and so choose to plaster that all over message boards every time Google is mentioned - exactly what are you accomplishing? Do you think the peopl…
Stupid that I didn't see this I should add. Considering I'm a programmer who knows how to do that with javascript, but for whatever reason it never occurred to me to do it or that others are doing it.
