text: This article "Making Mona Lisa Smile." shows many examples or evidence that support my claim like; " The facial expressions for each emotion are universal," observes Dr. Huang, "even though individuals often show varying degrees of expression" (like not smiling as broadly). Using video imagery, the new emotion-recognition software tracks these facial movements--in a real face or in the paited face of the Mona Lisa. Another example supporting my claim is " A classroom computer could recognize when a student is becoming confused or bored," Dr. Huang predicts. " Then it could modify the lesson, like an effective human instructor."
