Robot android FACE transmits human emotions through facial expressions

One of the ideas that form the basis of the principle of "Sinister Valley", which was developed by the Japanese Masahiro Mori (Masahiro Mori), is more than an android robot looks human and mimics human behavior, the more attractive it is for ordinary people to a certain limit, after which comes the backlash. And in yet another attempt to cross the principle of this "sinister valley" a team of researchers from the University of Pisa, Italy, has developed a new humanoid robot FACE, whose face can take a variety of expressions, sometimes, even the most difficult. By creating this robot, the researchers were intended searching for the answer to one of the fundamental issues of robotics - the robot can clearly express human emotions?

Latstseri Nicole (Nicole Lazzeri) and her team have designed an incredibly complex system of the robot face FACE, which is driven by electric motors 32, which allows the robot to realistically imitate the movements of almost all of the muscles and muscle groups of the human face. It is known that under the surface of the human face are about 100 muscles, which differ in form and function.

In order to realize the wealth of strokes with a total of 32 engines, the scientists had to write a special program called HEFES (Hybrid Engine for Facial Expressions Synthesis). The work of this program is to manage all engines on complex mathematical algorithms, which allow you to "play" on the face of all of the desired robot emotsii.Programma HEFES uses as a base system Facial Action Coding System (FACS), which describes all the patterns of muscle movements that correspond to certain human emotions. FACS system was developed by various scholars since 1978 and is widely used by psychologists, entertainers and other professionals related to human emotions. The software allows the operator to select HEFES initial face FACE robot and specify the sequence of emotions such as fear, anger, disgust, surprise, happiness or sadness, which should be reflected on your face robot android.
FACE robot participated in the experiment, which involved a group of twenty-five children, five of whom were autistic. These children had to identify emotions exhibited by first robot FACE, then scientists and psychologists. Autistic and normal children are easily able to identify sadness, happiness and anger, but the identification of surprise, disgust and fear in children caused some problems. The causes of these problems scientists have yet to understand, and presented at the video below you can see the face of FACE robot in action.
