| | Technology Review: How to Make a Robot Smile |
 | | Beginning in the 1990s, Hara's group set about creating six expressions-fear, happiness, surprise, sadness, anger, and disgust-which, according to Ekman, are universal to all human cultures. |
 | | These included an artist interested in creating what he believes is a new art form-humans and robots reacting to each other's expressions-and several psychologists in Japan who think such a robot could help certain handicapped children overcome difficulty manifesting appropriate expressions. |
 | | The psychologists would have the robot act as a kind of two-way prompt, for example, demonstrating what a happy smile looks like and, after assuming a neutral expression, indicating when the child has smiled by smiling back. |
