Emotional Fugitive Detector is a two-player cooperative game which uses the human face as both its primary controller and screen. One player’s face is scanned for emotions by the installation robot’s face tracking technology. The other tries to determine which emotion is being scanned for. Emotional Fugitive Detector embraces the affordances of human emotional expression, and subverts the concept of a controller. Instead of using the controller (a human face) to exert control, players attempt to send no input while evading detection. Players must find a difficult middle ground in this emotional Turing test: expressive enough for a human, too subtle for a computer.
