  In this poster, we present RealityDrop, a novel multimodal framework that
uses Mixed Reality (MR) technology to manipulate, display, and transfer virtual
content across different display systems. Employing MR as the centre of
control, RealityDrop affords concise information dissemination among diverse
collaborators, through varied representations that best fit each display
system's unique features using `superhuman' gaze and gesture interactions.
Three multimodal interaction techniques, a customised content interpreter, and
two cross-system interfaces are incorporated for fluent content manipulation
and presentation.
