چکیده

In this paper, we propose an interactive system for reconstructing human facial expression. In the system, a nonlinear mass-spring model is employed to simulate twenty two facial muscles’ tensions during facial expressions, and then the elastic forces of these tensions are grouped into a vector which is used as the input for facial expression recognition. The experimental results show that the nonlinear facial mass-spring model coupled with the SVM classifier is effective to recognize the facial expressions. Finally, we introduce our robot that can make artificial facial expressions. Experimental results of facial expression generation demonstrate that our robot can imitate six types of facial expressions.

Imitation System for Humanoid Robotics Heads

This paper presents a new system for recognition and imitation of a set of facial expressions using the visual information acquired by the robot. Besides, the proposed system detects and imitates the interlocutor’s head pose and motion. The approach described in this paper is used for human-robot interaction (HRI), and it consists of two consecutive stages: i) a visual analysis of the human fac...

Muecas: A Multi-Sensor Robotic Head for Affective Human Robot Interaction and Imitation

This paper presents a multi-sensor humanoid robotic head for human robot interaction. The design of the robotic head, Muecas, is based on ongoing research on the mechanisms of perception and imitation of human expressions and emotions. These mechanisms allow direct interaction between the robot and its human companion through the different natural language modalities: speech, body language and ...

Proprioception and Imitation: On the Road to Agent Individuation

Since Piaget, it is well accepded that higher level cognitive functions are settled on low level sensori-motor associations. In this paper, we will show that different kinds of interactive behaviors can emerge according to the kind of proprioceptive function available in a given sensori-motor system. We will study two different examples. In the first one, an internal proprioceptive signal is av...

A Facial Expression Imitation System for the Primitive of Intuitive Human-Robot Interaction

The human face has long been considered a representation of humans. According to observations of cognitive psychology, people unconsciously and frequently recognize and identify others from their faces. Many researchers have also emphasized the importance of the human face, e.g., Cicero said “Everything is in a face,” Darwin stated that “The human face is the most complex and versatile of all s...

Learning From and About Others: Imitation in Humans, Robots, and Animated Characters

We have implemented mimicry of facial expressions in an animated character as a first step towards adding a variety of imitative and social learning abilities to our existing character architecture. Our implementation draws inspiration from, and is heavily grounded in, the child development and comparative psychology literatures on social learning and imitation. Among the key ideas that we draw...
