Tangible Interfaces with Printed Paper Markers

This pictorial presents a design investigation at the intersection of paper and computer vision for tangible interfaces. Through this exploration, we uncovered various characteristics of paper that connect tangible interactions with concealing and revealing printed fiducial markers for detection—particularly through the affordances of paper craft and fiber. We illustrate a variety of paper structures that construct and deconstruct fiducial markers. We also demonstrate how these structures enable untethered functional physical inputs, such as push buttons and sliders. We showcase four proposals that extend these material insights into tangible interface applications, including interactive data physicalizations and functional paper prototypes. Furthermore, we continue the legacy of pictorials by exposing fabrication drawings for others to engage with this work at a more practical level.
