Existing technologies and known non-contact methods, like face detection and recognition applications, cannot reveal internal human emotions from neutral faces.
For security workers at border control (e.g. interrogation rooms) and police, it is crucial to swiftly identify dangerous subjects trying to perform unlawful actions.
Regardless of all current training for the interrogators, it is extremely hard to pinpoint what the interrogated subject thinks of. And in view of the interrogated person’s neutral face, it’s not clear to the interrogator, what this person actually feels at any given moment. This technology allows you to shed light on the feelings of the interrogated, even if he/she does not show absolutely any external emotions.
