We need an Indoor Positioning System to study consumer behaviour in real indoor environments (large rooms: e.g. supermarket), but I'm not sure which is the best technology for that aim (WiFi, radio signals, bluetooth, infrastructure-based, etc.). Given that there is no a recognized standard, I'm a little puzzled.
In any case, the system should be accurate (submeter accuracy, if possible), unobstrusive, user-friendly, easily deployable, stable enough, and, if possible, providing a good quality-price ratio. It is crucial that the system can register and map position, tracks, dwell times, etc. Any suggestions?
Many thanks in advance!
Dear Jaume, this is an interesting (but new) field to me. I did a brief Google Scholar search (please see embedded link). Some other RG members may be able to recommend systems from first-hand experience. Good luck!

Thanks you very much Leona! I'm also a beginner regarding these promising, but still "chaotic", pool of methods. I hope someone with first-hand experience could help us. Is there anybody out there? ;-)
Kind regards,
google tango has already done this, with aisle411, here's an article about that:

While I have read about this and understand the technology and the app, you will need to contact them about how you can actually get started on mapping your local environment/ store.
I'm not sure how easy and how expensive it will be to get their device! :)
there is a android/ios store app but that is for the consumer to navigate through the store (After it has been mapped already)

Submeter-accuracy is a tough requirement for indoor localization if there's no dedicated infrastructure in the building. Here are some commercial solutions available I know:
- Cognitec FaceVACS VideoScan: this generates location statistics from surveillance camera streams based on face analysis techniques
- KINEXON: indoor localization and statistics based on a network of wireless beacon devices (tracked objects have a receiver sensor attached that is located by fixed anchor base-stations)
- NavVis navigation app: a smartphone app & SDK for localization and navigation in indoor environments. This requires that the building was scanned once with the NavVis mapping trolley, but needs no infrastructure later in operation. The navigation app will be released soon, but you can already get in touch with the team if you have a use case.
Among them, only the face analysis based method is really unobtrusive - all others require the tracked persons to cooperate.

Great Michael! Yes, you're right. I probably need an IPS with dedicated infrastructure. FaceVACS would be ideal if not for the high cost. In any case, I would be willing to sacrifice unobstrusiveness in order to maximize accuracy and benefits of rigorous and comprehensive analysis.
Thank you very much indeed.
