Object locating: have you done it?

I’ve been very interested for some time in how you might go about tracking objects around a space, but I haven’t yet had a conversation with anyone in a museum who has actually done it.

This could well be because it isn’t yet do-able, or more likely I just haven’t found the right people to talk to yet.

Caution - RFID!As far as I can see there are a number of technologies which could be brought to bear, including RFID (limited range, not so much “tracking” as “identifying”, and even then of variable usefulness in a museum system). The systems recently written about on the BBC, however, use a series of wireless network points to pinpoint items within a space. I’d already looked at one of the systems written about – Ekahau – but hadn’t got much further than a brief email correspondence with their technical team.

The Ekahu system requires that you set up a number of (standard) wifi network points and then do a survey of the space – you essentially walk around and the system then maps out the various signal strengths, building up a map of the room or gallery.

The nice thing about this system is that to a certain extent it uses existing technologies – you may have to extend your wireless network points and install some software but that’s about it. The failure is that the accuracy is limited to metres – ok for tracking “assets” (including people!) in hospitals or schools, but limited for on-gallery or object store room use.

Where I know many institutions fail on this front is that it isn’t clear at all who should drive an object-location project. It’s very much the domain of curatorial staff, but IT, new media and interactive teams are all obviously involved as well.

I’d love to hear about any projects that have actually been done using location based technology. I’ve done lots and lots of reading of papers suggesting various solutions but what I’m interested in here is real world application. Has anyone done it?

  1. Hi Mike

    I for noe know of two projects here in Copenhagen. One is not yet started, but is funded by now, and is linked to the exhibition about industrial culture I’m working on, Brede Works. We consider RFID, but at this moment all is very open. We want to connect three exhibtions through this meiida, so if you have any advice or reference for us, it would be apreciated greatly. The other project is also at the national museum, and is a GPS-game that interpretes a series of old houses in the open-air part of our museum. Youu should try that, even though it’s in danish…

  2. hey mike —
    this article found it’s way into my ‘museum tagging’ alerts today — don’t you love the precision of keywords 😉 it’s mostly in your category of talking about possibilities:
    Ryan Kline “RFID leaps from the warehouse to the art museum, Galleries are tagging collections to improve inventory control, security, and the total customer experience” SecureIDNews. Tuesday, May 22 2007 – here
    There was also an RFID workshop @ MW2006 by Bert Degenhart Drenth of ADLIB Information Systems – see here Have you heard from him? jennifer

  3. Thanks both, appreciated. I’ll check out the links. If you spot anything else, do let me know..

    What I’m interested in is systems which actually let you track stuff *around* a space – so rather less “scan this object” from close quarters and more “what objects are in this space and where are they?”

    I’m not 100% sure this can actually be done, although the Ekahau service seems to be along the right lines…

    cheers

    Mike
