Sibylle Feucht, a Swiss artist, living in Bonn (GER) is showing new works from 2015 under the title "Interface Error", also the name of a photohraphic series exhibited.
A simple definition of Interface is the place or area at which different things meet and communicate with or affect each other. Based on this definition interfaces are just everywhere, physical and mental. If such an interaction is judged as something successful or as failure depends exclusively of the taken point of view.
