MagicScroll: A Rollable Display Device with Flexible Screen Real Estate and Gestural Input

We present MagicScroll, a rollable tablet with 2 concatenated flexible multitouch displays, actuated scrollwheels and gestural input. When rolled up, MagicScroll can be used as a rolodex, smartphone, expressive messaging interface or gestural controller. When extended, it provides full access to its 7.5 '' high-resolution multitouch display, providing the display functionality of a tablet device. We believe that the cylindrical shape in the rolled-up configuration facilitates gestural interaction, while its shape changing and input capabilities allow the navigation of continuous information streams and provide focus plus context functionality. We investigated the gestural affordances of MagicScroll in its rolled-up configuration by means of an elicitation study.
