Flexpad: Highly Flexible Bending Interactions for Projected Handheld Displays

Flexpad is a highly flexible display interface. 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 in real time. This approach captures deformations in high detail, is very robust to occlusions created by the user’s hands and fingers, and does not require any kind of markers or visible texture. 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.
