here is a review of recent work on tracking visitors, including an
RFID study:
http://www.archimuse.com/mw2009/papers/baldwin/baldwin.html
here is info about cost: ranges from $100-$2000 for a reader
http://www.rfidjournal.com/faq/20
I don't know what the possibilities would be for having multiple
readers covering a space to get finer location info, or for having
multiple antennas time shared by a single reader... without some such
arrangement one would need one reader per spatial zone one wanted to
discriminate, which would make identifying the specific object a
visitor is viewing expensive for any meaningful scale.
The Exploratorium used badge readers, one per selected exhibit, but
these do not have the accessibility advantages that reading from a
distance would have.

I wonder how many RFID towers the museums would have to have in
place to achieve resolutions comparable to the other methods being
described (?)

Subject: "inverse" RFId
having belatedly looked at the page on in-museum services, I want
to promote the "inverse" RFId approach that's mentioned within
the RFId section... the idea being that visitors, not stuff in
the museum, get tagged
seems as if this has powerful advantages with respect to all of
the alternatives besides image recognition
in particular, visitors don't have to be assumed to bring any
device, to get some benefit (eg a map of their visit for access
later)
if the visitor does have a device, it only has to have web access
to deliver useful stuff, if one arranges a match up of visitor's
device to visitor's tag (a possible scenario: on the way into the
museum, wearing your rfid tag, you pass through an entry big
enough only for you... on your phone you go to a website that
knows which tag is in the entry at that moment, and your phone
thereby picks up what your tag is... thereafter the website
content is targeted to you based on the location of your tag)
seems to me all of the alternatives, including image recognition,
make considerably heavier tech demands on what visitors have to have
