Blade Runner’s Voight-Kampff Test Gets Real

You’re in a desert, walking along in the sand when all of a sudden you look down and see a tortoise. It’s crawling toward you.

Any Sci-Fi fan knows this is a question from the iconic Voight-Kampff test, as made famous by the movie Blade Runner. Humans pass the test. Replicants fail and are “retired”. We may not have replicants just yet, but  [Tom Meehan] is building his own version of the Voight-Kampff machine. He’s entered it in the 2017 Hackaday Sci-Fi Contest.

The machine itself is an odd mix of 70’s and 80’s electronics with older technology. Three mini CRT displays, a sensor arm, and a bellows are some of the machine’s best-known features. [Tom] is starting with the sensor arm, an odd mix of belts and telescoping rods. He’s already got a manually operated prototype built. Add a motor, and one part of the machine is ready for action.

[Tom’s] version of the Voight-Kampff test isn’t going to be a just movie prop. He plans to add a sensor suite which will turn his machine something of a modern polygraph. A Non-contact Temperature sensor will measure blush response. Iris images will be captured by a Raspberry Pi NoIR camera. Pulse oxygen and galvanic skin response will also be captured by a separate hand module. All this data will be processed by a Raspberry Pi computer.

There’s quite a lot of work to be completed. Let’s hope for humanity’s sake that [Tom] gets it done before the contest deadline of March 6.
