I developed a fully functional polygraph machine as part of my work within the transmedia collective ‘Counterpilot’. Custom software inferred a lie likelihood from biometric stress markers obtained from three different sensors. My custom built hardware broadcasted OSC messages that were used to dynamically alter the audio and visual environment of the performance. Truth Machine explored truth in a world of fake news and alternative facts.
