Knock Knock by Khalil Klouche, a graphic and media design student at HEAD Geneva University, is a calculator for kids. A clever tactile creation, it revolves around the idea of knocks, hence its name. Essentially, a child (or adult, for that matter) is encouraged to knock a calculation on it and it proceeds to knock back an answer. It not only teaches them the basics of math, but it also fosters their imaginations as they wonder about the little person residing inside.
Made out of Arduino board, contact microphones and solenoids, Knock Knock by Khalil Klouche was created for the Touch! exhibition at the Museum of design and contemporary art (MUDAC) in Lausanne, Switzerland. It will also be featured at the Lift conference.
