The Human Media Lab at Queen’s University in Ontario's new project, DisplayStacks, uses several flexible E Ink panels together that communicate between them using sensors to integrate them into a compound display.

The researchers explain that DisplayStacks basically enables physical stacking of digital documents via piles of flexible E Ink displays. With a conductive dot pattern sensor attached to the flexible dis- play, the system dynamically tracks the position and orientation of these displays in relation to one another. This enables several asymmetric bimanual interaction mechanisms for access and manipulation of information.
