Microexpression Tracking Software
Researchers from Oxford University as well as Oulu University (Finland) are developing software that can detect an individual’s micro facial expressions.
Microexpressions are concealed signs of emotion that flash on and off a face when a person is trying to hide their emotions. According to Vision Systems Design this product can be used to train government and airport officials to detect suspicious behavior.
While having the ability (or software) to recognize micro facial expressions is one thing, it is a completely different thing to use that information to detect deception and uncover the truth.
Dr. Matsumoto affirms that microexpressions are not indicators of lying but are clues that a person is hiding something and there is more to the story than is being conveyed.
