Indoor Positioning

Hi folks,
Is there a way to get accurate positioning (within 1m or less) of a POI in Layar in an indoor environment? I looked at Qubulus based on an earlier discussion, it was promising but unfortunately I need a solution that works on iPhone and Android, Qubulus is only Android.
I have seen an example mentioned online this week (many, many times ... if the author is on here, congrats!) that uses a QR code on a store front and once inside the store, art work is displayed on the walls. The article is at http://creativity-online.com/news/virginia-museum-of-fine-arts-pica... . If anybody has a video of this project, I'd like to see it. I assume the QR code is being used as an reference/location marker but how does the phone know how far and in what direction you have moved from that point?
Any help would be greatly appreciated.
Thanks in advance.
Glen

Hi Brian,
This is the open forum that all signed in developers can use to create a new topic. Private question goes to a closed ticketing system. We strongly recommend developers to ask questions on the forum so that other people can benefit from the answers.
About your issue, I am suspecting that you have set an "alt" in the JSON response. Can you tell us the layer name and also which layar client you are using ?
Thanks!

I'm wondering if my issue is the same:
I modeled a figure that I wanted to view as a figure in my home, to test to document the modeling, texturing and layer procedures.
I modeled and textured everything correctly, but when I try to view the layer, my model is always directly below me. I walked all over my house, and refreshed my layer, and the model is still always directly below me.
I have no idea if I'm just doing it wrong, or if it's a glitch in Layar, or what.
I wouldn't have gone on and on about it here, but I have no idea how to ask a question in this forum, even though I'm signed in, I only see a button for "ask a private question"...are all of these questions in the forum "private" questions that later become public? Oh well.
Yes. this particular application is going to eventually be there.
It will not work with GPS or compass once you approach and enter a facility.
first is waypoints. there will need to be waypoints that can be captured within a facility. AR api's contain pattern recognition and could be used to help this.
the second is a 3 axis gyro will be required.
The camera will need to be able to recognize facility waypoints or require user registration, then use the gyro to navigate through a facility.

Hi Stephen.. Have a look at the Layar Augmented Office app... It seems to base itself on your current location regardless of your location moving (whether by you moving or the GPS getting it wrong) it does however react to your direction, presumably based on the compass. With some lateral thinking and a bit of work this could be a way of doing indoor spaces..
Perhaps the nice people at layar will let us know how this is done.

That video shows how the qr code can align the 3d object. I guess it does, I don't really understand it. I would like to create a layer that opens with a qr code and is aligned to the r
gps reading of the phone at the moment of decoding. Problem is my phone wont keep the same location. It does in gogle maps (not perfect but close) but in Layar i'm jumping all over the place. Either way its not gonna be accurate enough to keep a picture on a wall.
Hi Glen,
I am sorry but I'm not familiar with this specific project/layer. I would suggest you contact the developers for more details :)

Hi Pambo,
Thank you for your input. It appears that the Virginia Picasso exhibit campaign is using some form of indoor solution with Layar based on the article linked above. If indoor implementations aren't accurate, how can they position the art work on the walls of the Starbucks locations? Can the viewer move around the Starbucks and view the art work from different locations but still have them appear at the same location relative to the walls of the Starbucks?
Thanks again.

Hi Glen,
Layar only uses GPS for positioning. This is the reason why sometimes it is not that accurate in indoor environments. There is ongoing reseach for alternative ways, but nothing available right now.
