Voight-Kampff machine

Part of a Voight-Kampff, in the process of conducting a test.

The Voight-Kampff machine or device is a fictional tool originating in Philip K Dick's science fiction novel Do Androids Dream of Electric Sheep?. Spelled Voigt-Kampff in the book, it also appeared in the book's screen adaptation, the 1982 film Blade Runner.

Operation

The Voight-Kampff is a polygraph-like machine used in the film by Blade Runner units to assist in the testing of an individual to see if he or she is a replicant. It measures bodily functions such as respiration, "blush response", heart rate and eye movement in response to emotionally provocative questions.

Capillary dilation or the so-called blush response … fluctuation of the pupil, involuntary dilation of the iris....

– Dr. Eldon Tyrell, Blade Runner

In the film two replicants take the test: Leon (played by Brion James) and Rachael (played by Sean Young). In Blade Runner, Deckard tells Tyrell that it usually takes 20 to 30 cross-referenced questions to distinguish a replicant. With Rachael it takes more than one hundred. This should be contrasted to the book where it is stated it only takes "six or seven" questions to make a determination.

"A very advanced form of lie detector that measures contractions of the iris muscle and the presence of invisible airborne particles emitted from the body. The bellows were designed for the latter function and give the machine the menacing air of a sinister insect. The VK is used primarily by Blade Runners to determine if a suspect is truly human by measuring the degree of his empathic response through carefully worded questions and statements."
