(from Barbara Nordhjem's site:
Together with Jan Klug and Bert Otten, I wrote an article about the (e)motion installation. It has been accepted for publication by Leonardo and you can read the preliminary version here.
We humans express what we think and feel by facial movements, often without even realizing this. In the installation (e)motion, the goal was to create awareness of even the most subtle movements of the face and create a space for interaction purely based on facial expressions. Facial movements were tracked by custom software and translated into motion vectors, which were visualized and coupled with sounds. Participants could interact by responding to each other’s facial movements. (e)motion was inspired by embodied cognition and scientific studies on emotion and action. The installation was the result of interdisciplinary collaboration between art, movement science, and cognitive neuroscience.
