Polygraph equipment for £150 or under?

[Amplify]

Hi there

This might be a little bit of an odd question, but I'm counting on the chance that one or a few users happen to know of something similar to what I'm looking for as being available to purchase from wherever.

I'm looking for a way to remotely monitor a human being's heart rate, (and preferably other statistics such as respiration and / or blood pressure, and so forth) in short, a polygraph (lie detector) test machine.

It needs to fall into the following requirements:

1: Measures a human being's heart rate (and preferably other readings too) as a timeline which can be viewed by an operator without disturbing the test subject to see the readings. I.e: The operator can later see that at 1 minute the user had a heart rate of 60 beats per minute, then suddenly at 1 minute 20 seconds something happened to cause thier heart rate to jump up to 90 beats per minute, which 20 seconds later returned to 60 beats per minute, etc.

2: Available for £150 or under

3: It doesn?t have to be commercially available to the general public, but it DOES have to be available to a university for academic purposes.

Does anybody know of anything like this or similar available for purchase?

Blood pressure's a tricky one, as that tends to involve having to keep a pressure cuff on them for x amount of time.

Standard gym heart rate monitors are wireless, so as long as you're *fairly* close to the transmitter on the subject, you can get real-time information, if you look around some might have a data logging facility.

One search on ebay nets me the following: http://cgi.ebay.com/POLYGRAPH-MACHINE-STOELTING-ULTRASCRIBE-ANALOG_W0QQitemZ160336383533QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2554cb0e2d&_trksid=p3286.c0.m14&_trkparms=66%3A2%7C65%3A15%7C39%3A1%7C240%3A1318%7C301%3A0%7C293%3A2%7C294%3A50

There are other things but they don't seem to be actual polygraphs (I can't imagine them being like 40 bucks..)

Auctions are a tricky one, and makes me realise another requirement (technically)

4: It needs to be available for purchase today, this week, next month or even next year. As such auctions are not really appropriate, due to the unstable nature of when they can be purchased.

No thankyou.
Polygraphs prove absolutely nothing, anyone who says otherwise watches too much television.

I'm not after a way to tell if somebody is lying or not, I'm just after a way to get a time graph of a person's heartbeat and / or other similar measurements without being forced to disturb the test subject by checking a wrist mounted heart rate monitor or something similar.

But don't you need it now?

Speaking as someone who is trained to use one of these bad boys.
It takes training to understand the readings it's not like TV where lots of movement equals a lie.
I still postulate that it would more accuratly be called 'a stress detector' chances are if you're really stressed you're probably lying. But the PGraph rarely will be admitted to court as evidence.
It can however, be used to gain a warrent or used to gain other evidence and is rarely considered a poison tree from which to get more evidence fruit.

The cost? Well 150 pounds is like $230 american or so right? Yeah I'm gonna say no the ones that Police Stations use are about a thousand bucks (800-900 pounds I think). Part of that is software and training too though.

As far as how it attaches it's pretty obtrusive. You put a band around the subject's head, arm, a waist you also attach a clip to the middle finger

I apologize if my $ to £ is completely off I'm half guessing.

I need it "at a point in the near to not too distant future, to be specified at a later date"

To be honest, I could care less if it's for testing if somebody is lying, or whatever else, I just named a polygraph as it measures a person's statistics and gives a reasonable timeline graph of their vitals at any given moment, which is exactly the sort of things I'd need.

Currently I've been trying to use an exercise heart rate monitor for what I'm trying to achieve, but the results can only be gotten via a wristwatch that the subject is wearing, so it makes it almost pointless as I would have to keep interrupting them to get a look at the watch, and it doesn?t record what the heart rate WAS, only what it is at the given time.

 

[Amplify]

Anybody else? If it's simple that's fine, so long as I can get a pulse (and perhaps more) recorded down electronically or on paper, telling me what they felt at a given time.

Again, note that I'm not necessarily after a polygraph or way of telling if somebody is lying, just remotely monitor for changes in life signs, such as a polygraph does.

Just wondering, but why do you need a polygraph? And polygraphs can't monitor people's heart rates remotely, they have to be hooked up to the machine.

 

[RapidCrash]

I would also have to say that what you're looking for might be fairly unreasonable.

I am, of course, assuming it would first of all need to be digital. Even a simple analog polygraph would run for around the amount you're looking for. To add a digital system and display would be much more work on them as well.
Now "truth detector" or portable versions usually wouldn't do what you need them to do. It seems that a simple heart-rate monitor would easily suffice with what you're attempting to accomplish, but you might have issues finding one that has an external display. I say good luck to your search, but you might want to consider revising what you're looking for.

How far away do you need to be? I've got a cheap Oregon Scientific HRM, and the watch can pick up from the chest sensor about 10 metres away.

In short, it's for a scientific experiment I'm conducting, which involves various custom made horror based game levels and monitoring the various user reactions and responses to said level.

Thread can be found here:
http://www.escapistmagazine.com/forums/read/9.110321

I just need to be able to ANY kind of recording of some sort of reaction of theirs over time, whatever it may be that I can then compare to a frapsed video of their progression through the level. I will then take this information and a short questionnaire to come up with plottable results. If I have to, I'll go with a camcorder recording their facial reactions and use that, but the two problems I'm encountering with other monitoring devices are that I need to repeatedly disturb them to look at the wristwatch mounted results (using a simple heart rate monitor intended for joggers), and that if I don't immediately record said results, they are lost to me forever.

I would also have to say that what you're looking for might be fairly unreasonable.

Digital, analogue, anything will do, even if I have to manually take a piece of paper and write down the results furiously while comparing them alongside a stop watch. Just so long as I don't have to disturb the test subject constantly to get said results, and ideally, I don't have to furiously write down the results myself. But I'll take almost anything.

Even one meter away would do, but as I currently reside in England it would be hard for me to pop over to Oregon to purchase one.

Got mine in Leicester Oregon Scientific's just a company. Best bet is to check Amazon, cheapest way to do it.

If you mean this, it looks almost identical to what I am attempting to use right now, and it struggles to function at all when any further away than the user's wrist, making it rather unwieldy. Even if it is more efficient, it would be difficult to justify the purchase of it due to it being near identical in looks, use & function. This is why, in an ideal world, I'm looking for something that records to results for me using *any* method, to eliminate that problem from the equation.

 

[deathninja]

Not the one, but now this is going on a tangent.

At any rate, only really suggested an HRM becuase they're a compact solution, fairly cheap and some (Garmin come to mind) can sync with PCs, some log HR this way, some only pace. I'm afraid I don't know specific examples.

You're at a uni right? Might be worth emailing the track/running society if there's one, maybe someone can give you advice, or try out a buit of kit.

If you find a solution like that, great. If not then keep looking. Best of luck with the project.
