The study of emotional facial expressions and of emotional body language is currently receiving a lot of attention in the cognitive sciences. In this project, we are not studying particular emotional gestures, but rather focus on the implicit bodily expression of emotions during standard motions such as walking forwards.

An underlying assumption of our work is that all human motion is optimal in some sense and that different emotions induce different objective functions, which result in different "deformations" of normal motion. Our analysis is based on whole-body dynamic models of the walking subjects as well as our previous work on generating complex locomotion by means of optimal control techniques and on the identification of human objectives by means of inverse optimal control.

The work is being performed in cooperation with the group of Prof. Alain Berthoz from the College de France in Paris, who is an expert on the perceptive and cognitive aspects of motion and is providing experimental data on walking motions in relation to different emotional conditions.
