Cool, open-source take on indoor positioning
From 2 comments
Cool project. I have tried using both wifi and IMU motion sensors for mapping indoor and it's not really that impressive yet. This is still a very hard problem to solve. Google…
asadlionpk on HNAwesome. I tried creating something like this to help get around our very confusing corporate headquarters, but gave up. I will almost certainly use this now!

Accuracy around 10 square feet is impressive
From 1 comment
They claim a typical accuracy of 10 square feet (< 1 square meter) which would be really really good. Even systems with beacons are not better.

Motion detectors have a variety of usage, outdoor lighting, indoor room lighting, grocery store fridge lighting, etc. FIND is a bit more specialized because of the huge drawback…

Lower resolution details in the description
From 1 comment
~10sq feet in resolution Seems like that should be in the first 3 lines of the description, not near the end of the FAQ. Very cool project.

How the Naive Bayes classification works
From 1 comment
I've looked through the code to get a better understanding of this process, but I couldn't get my head around it. Could you give a more detailed description of this process?

Whether fingerprints can be shared between devices
From 1 comment
Once finger printing has been done can that info be shared with other cell phones?

Bluetooth LE beacons

Can some one explain me, why just not use bluetooth LE? I understand you need BLE beacons, but any other reason.

Motion sensored room light has been available for at least 15-20 years.

Inertial navigation
From 1 comment
What is wrong with inertial navigation? Just need to mark a starting poing ( like, your house door ) and then just walk around and mark the places. I've seen in the past some…
