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
