Human Hand Clamp 

By FAU Division Of Research

Boca Raton, Fla. – August 13, 2014
Scientists at Florida Atlantic University's Center for Complex Systems and Brain Sciences have created the Human Dynamic Clamp to address the difficult problem of studying social interactions in the laboratory. The Proceedings of the National Academy of Sciences published their study findings on Monday.

Using state-of-the-art human-machine interface technology, the Human Dynamic Clamp works by having humans interact with a computational model that behaves very much like humans themselves. In simple experiments, the model - on receiving input from human movement - drives an image of a moving hand that is displayed on a video screen. To complete the reciprocal coupling, the subject sees and coordinates with the moving image as if it were a real person observed through a video circuit. This social "surrogate" can be precisely tuned and controlled - both by the experimenter and by the input from the human subject.

The article published in the peer-reviewed journal is titled "The Human Dynamic Clamp as a Paradigm for Social Interaction." The research was supported by an NIMH grant to Drs. Kelso and Tognoli. READ MORE .
