The industry name for a lie detecting machine is a polygraph. 'Poly-' means many or lots and '-graph' refers to writing or the recording of information. This is essentially what a polygraph does, measuring and recording information from multiple sensory inputs that can be interrupted to show how comfortable a person is at a certain moment, or series of moments, in time.
Polygraphs work on the assumption that people telling lies are uncomfortable. Maybe not very much, but nevertheless they feel differently to when they're telling the truth, resulting in changes to heart rate, breathing, perspiration and so forth. A polygraph test assumes that these are involuntary changes to your body which always occur when you lie. This alone means that pathological liars often fool lie detector tests because they show no change when they tell a lie. However, taken together, it is assumed there is enough of a change in the readings between truth and lie to be able to make a definitive decision.
A polygraph interview will usually take several hours, and takes place in a room where only the interviewers, who like to be called forensic psychophysiologists1, and the subject are present, although others can be watching from behind one-way mirrors. First the examiner and the subject have a basic chat, where the examiner calibrates the equipment, and tries to put the subject at ease. The actual test comes later when the examiner asks several relevant questions and also some control questions to check that the responses are still the same. Analysis of the questions takes place afterwards.
