For millions of successful poker players, the key to outwitting other players often rests in the face. The'poker face' -- a blank expression that never gives away a good or a bad hand -- has become one of the most iconic looks associated with professional poker players. A new artificial intelligence system might change that entirely. In a recent TED Conference talk, Dolby Laboratories chief scientist Poppy Crum detailed the company's new innovation that could see right through someone's expressions. Dolby developed a combined sensor and AI system that can tell whether someone is lying, infatuated, or posed for violence, Crum said at a big ideas TED Conference.
