text: Huang also goes on saying that he can pin point out emotins on kids in school. In my defence I dont this this would work accuratley. Not only do i think it would work. Many of teacher would not want to get out that device in the middle of class just to see your kids emotions. Many of kids fake smile or act like they are happy when really they are not. Studies show that they are identified by the muscles but you could easlily get told to smile which changed your muscles which changed the game.
