foldable

Modern computer displays tend to be in fixed size, rigid, and rectilinear rendering them insensitive to the visual area demands of an application or the desires of the user. Foldable displays offer the ability to reshape and resize the interactive surface at our convenience and even permit us to carry a very large display surface in a small volume. In this paper, we implement four interactive foldable display designs using image projection with low-cost tracking and explore display behaviors using orientation sensitivity.

This paper presents Foldable User Interfaces (FUI), a combination of a 3D GUI with windows imbued with the physics of paper, and Foldable Input Devices (FIDs). FIDs are sheets of paper that allow realistic transformations of graphical sheets in the FUI. Foldable input devices are made out of construction paper augmented with IR reflectors, and tracked by computer vision. Window sheets can be picked up and flexed with simple movements and deformations of the FID. FIDs allow a diverse lexicon of one-handed and two-handed interaction techniques, including folding, bending, flipping and stacking. We show how these can be used to ease the creation of simple 3D models, but also for tasks such as page navigation.
