Double-Sided Touchscreen Changes When You Fold It

Juergen Steimle, working with developer Mo Khalilbeigi and his team at the Darmstadt University of Technology, Germany, has developed a range of foldable displays that support novel user interactions.

Steimle has created a projection-based display that tracks movement. The display uses six overhead infrared cameras and two high-definition digital projectors, and projects onto a passive white tablet also created by Steimle. The user holds the tablet, which contains sets of spring-loaded, reversible hinges so that they can be folded like a book or a pamphlet. The system monitors the way the tablet is folded, using the act of folding and the resulting form as a means of interaction, and will treat a flat tablet as one display and switch to a two-display mode when the tablet is bent in the middle. When the tablet is closed, the menu options can be displayed on the cover to alter the contents inside. Users also would be able to adjust the color, contrast, volume, and other settings because the cameras are able to detect the angle of rotation on the hinges.

Steimle will present his work this month at the Tangible, Embedded, and Embodied Interaction Conference in Kingston, Ontario.
