A funny problem

Hi all,

I have a request from a customer about a software that would "know
where it is in a building". It's a sort of hospital, so when personnel
walks from a room to another, their palmtop should "sync" to the
people who are hosted in the room. I could think of putting a bar code
on the door, but this means that if the operator forgets to read the
barcode on entering the room he'll be out of sync. And the more the
call is urgent, the more he is likely to forget about the code,
especially in the beginning.

So I'm asking myself whether there is something that we could hang
somewhere in the room, and that could be automatically "read" read by
a palmtop. Next question is whether (and how) I can read this device
from gst, obviously.

Thanks
Bèrto

I think it should be possible to tune wifi-spots in hospital to give unique answers on some URL, while still sharing the common network-name.
Then, you just need to have a thread, which will be constantly sending http-requests on that URL

Ah, got it, you made my day, thanks :) Yes, it looks quite simple.
I'll take a serious look at the threading thing.

Hi!

> cheap RFIDs attached to the doorframe?

That would be the basic idea, but how do you use them with gst? Is
there any ready/solid lib to manage them? Probably a stupid question,
but since I never used RFIDs I'd hate to find out an endless amount of
trouble after accepting the job.

Just a random pick from googling "usb rfid reader linux"

http://www.b-production.org/brosura_ang_print.pdf

"Once the reader is plugged to the PC with Windows, Linux or
MacOS operating system, the system recognizes it as a HID
(Human Interface Device) keyboard, and therefore doesn't
need any special drivers to function properly."

Looks like they do what barcode scanners do: behave like a
keyboard. So if you go that way, you now know that there is
"easy" hardware.

Come to think of it, if it's to be deployed to a hospital,
make sure that these things don't interfere with any medical
equipment.

hehe ... I remembered the "no mobiles" signs on the doors of our
local hospitals. However, if RFID chips were subverting medical
equipment, I'd have to leave my car keys at the door, too. And are
you, really, really, really sure that there is no active RFID left
somewhere on your clothing? Or on the mechanical pencil you bought
for your sick friend's crossword solving needs?

Still, showing concern won't hurt the reputation, I guess.
