A particular aspect of human-machine interfaces is that they are just that: interfaces — dynamic information devices through which data are transmitted in one direction. Artists have always been explorers of human feelings and perception. That holds true today, when they submit their own bodies to interaction with machines. As with many digital media or arts performances, the audiences attracted to such works are generally aware of what they are going to see, which means they are better prepared than the general audiences. For these reasons, our lab encourages collaborations with professional artists to explore human-machine interaction and interfaces.
