I started to do a just bit of web research in this. Open source barcode
photo recognition software looks like it's _just_ starting to become
realistically available. This was the product that looked most
promissing in my web research (not sure if it's what the Android app is
My Umlaut software would be an _ideal_ end-point of barcode recognition,
is why I started to look into it. Umlaut is designed specifically to
meet the goal of taking a known item citation (such as an ISBN, sure),
and returning a range of library availability and services for that
The next step, which I haven't figured out yet, is how to get your
software to participate in MMS/SMS architecture -- in particular to
receive MMS/SMS messages in a way that's affordable to you and
convenient to your users. (It looks like some but not all cell phones
can send MMS messages to email, but not necessarily as conveniently as
sending MMS to a cell number; but I'm not sure if there's a cheap way to
have software receive MMS messages at a cell number. The Android app of
course performs all it's processing on the Android itself, which you can
do on a device-by-device basis for devices powerful enough for that; but
I too am attracted to the idea of an MMS solution that would work on any
MMS capable device, with no need to customize per device).
I also haven't actually looked at the zxing code yet.
But I'd love to have Umlaut able to receive an MMS message, and give the
user back a concise list of library services/links. So many interesting
projects, not enough time.
