Lie to Me is an experience that teaches kids and adults about micro-expressions. When lying, the brain reveals its inner state through micro-expressions that cannot be controlled. I prototyped Lie to Me while working for the Franklin Institute. This digital interactive involves two players, one interrogator and one liar, facing each other across a table. They interact face-to-face and with two touch screens. A webcam is recording the liar every time the interrogator asks a question. The interrogator's objective is to analyze three video recordings of the liar and look for micro-expressions, and finally, choose the answer that contains the lie. This experience was developed using processing.
