Flexpad: a highly flexible handheld display

Abstract

This video demonstrates Flexpad, a highly flexible display interface. Flexpad introduces a novel way of interacting with flexible displays by using detailed deformations. Using a Kinect camera and a projector, Flexpad transforms virtually any sheet of paper or foam into a flexible, highly deformable and spatially aware handheld display. It uses a novel approach for tracking deformed surfaces from depth images very robustly, in high detail and in real time. As a result, the display is considerably more deformable than previous work on flexible handheld displays, enabling novel applications that leverage the high expressiveness of detailed deformation. We illustrate these unique capabilities through three application examples: curved cross-cuts in volumetric images, deforming virtual paper characters, and slicing through time in videos.
