Education is increasingly involved in emerging technologies and Human Computer Interactions, and the costs to keep up with the trends are directly related. Printing computer vision fiducial markers on cheap craftable paper makes them cost effective to use in class rooms, as buttons or sliders. This project modifies buttons and sliders in a way the markers can change shape and value. The change in value during the operation of the activators creates richer and more accurate data, which can be used for better and smoother control while the same tangibility of the activators remains.
