Quote:Until you know what is being measured and the questions being asked, how can you form an opinion regarding the use of this technology?
(Edited for syntax and spelling)
As George mentioned, this is very likely a galvanometer (a GSR-measuring device). Pulse might be measured, too. Unless they're measuring body temperature, a test which I don't know exists, that's about all you can measure accurately. If they're reading palm prints, then welcome to George Orwell's 1984.
They won't waste their time asking irrelevant questions, presumably. If airport authorities have in mind to keep evil people off planes, they'll ask your itinerary, the purpose of your trip, if you've ever done this or that, and so on. That's not a big stretch. The technology, btw, already exists, and it's bundled into the fraud we call a polygraph.
Quote:No one on this or any other board is even remotely familiar with the instrumentation, questions, research or actual results.
Perhaps not specifics, but again, the technology that does exist for "lie detection" or the scanning of parts of the body (retinas, palms, fingerprints) lends itself in good part to this idea. There is no instrumentation out there as of now for this, nor has anyone written questions for its hypothetical use, and there thus can be no actual results. Research, while not specific to this conjectured device, can be had by studying the galvanic readouts on polys and their subsequent (mis)use. They're not going to reinvent the wheel to put this thing in the terminal; the government will simply ask someone with expertise in the channel to be studied to come up with, well, whatever they want to use.
Quote:How can you make such definitive statements? I would think one would want information and research to back up such statements.
I do want research and information. I am theorizing here, but I can't see it as a huge stretch to submit that a GSR palm- or finger-reader will be the preferred choice, if this ever comes to fruition. I hope this clears up that I am not trying to tell everyone what to expect...
