it should still work with signal repeaters. Did you map the location first? If this is a new location (i.e. someone else hasn't mapped it yet), then what you want to do is select the floorplan in "Browse Floorplans". You should see a button to start mapping, hit it & follow the on-screen instructions (basically walk around and hit the "mark point" button or the volume up/down button after positioning yourself on the map). once you are done, hit stop mapping & hit yes to upload it to our servers for processing. after some time (maybe 2-5 minutes depending on load) you should be able to hit "Where Am I?" on the home screen to have it track your position.

Let us know if it's still not working for you.

The current WiFiSLAM SDK is an Android java library, available as an Eclipse project with sample code snippets that allow you to add your location to any existing Android app.

We have an iOS SDK that works, unfortunately since Apple disabled WiFi scanning in iOS 5 we can no longer publish it. It still works on jailbroken devices, but not a big target audience. We have a workaround in the works that will incorporate iOS devices

Yeah, Aisle411 is definitely doing some cool stuff with indoor location, and are the types of partners that make a lot of sense for us. Indoor location is made up of two key components: Real-time positioning (e.g. WiFiSLAM) and point-of-interest databases (e.g. Aisle411)

yup, that's right

thanks! How small are the movements you’re trying to track? And what kind of time delays are you trying to get under? You can try mapping the same location multiple times (the more mapping the more accurate our system will be)

Does it work if you try again? Looks like this is an issue with mod_python, which cannot accept chunked encoding (https://issues.apache.org/jira/browse/MODPYTHON-222)

We’re not sure under what conditions the client decides to send chunked vs not, but in our testing if you retry it should get through.

We’ve found good results using only the configuration phase; we have versions with full SLAM but it tends to work well without it. The QuickMap app uses only access points detected during the configuration phase.

A lot of people just scribble down a drawing on paper, and then use the "I Want To Take A Picture With My Camera" option. The floorplan is just a reference point, so you can makeup whatever floorplan makes sense for you. For example: https://lh4.ggpht.com/Y1z9Qt5EggwNdg0Caua9dJGWV8dZmnYhioten1...

you're right. we're working on a blog post describing the app, and should probably get a better description on google play

No specific requirements for wifi at all. Which part didn't work exactly?

strange! we're looking into it.

meanwhile try scribbling it down on paper and taking a picture of it :)

It will work wherever there are ambient WiFi signals, indoors or outdoors. This is particularly interesting indoors because it’s possible to get GPS outdoors, while you can’t indoors. We have tried mapping around Mountain View and it’s worked great

We built this because we felt Indoor Location technology is too inaccessible. There's lots of buzz about indoor location, and many canned demos, but very few people seem to put it out there.

We've built some cool tech, and we want people to try it out first hand.

I used Amazon Fresh when I lived in Seattle & Redmond; and I think this appeals to a different impulse. The key with Instacart is it's (almost) instant, Amazon Fresh is not. The "hey I'm setting up for a bbq, and I need to a couple things from the grocery" is not possible with Amazon Fresh. Whether or not it's a big enough market... I guess they're going to find out!
