From "Envision, Invent, Inspire: MIT Media Lab's Tangible Media Lab Presents, Part II" at the 2013 Aspen Ideas Festival.

Three MIT Ph.D. candidates present their research. Daniel Leithinger proposes that information can be conveyed by changing the shape and material properties of physical objects. His actuated tabletop display Relief renders and animates shapes, which users can touch and deform with their hands. Xiao Xiao is interested in how we can interact with information the way we interact with music, not with the abstract content perceived consciously and intellectually but as moving, visceral experiences. She will present MirrorFugue, an interface for interaction with remote and recorded piano performances that viscerally evokes the presence of pianist. Lining Yao will demonstrate that the physical world can be programmed, diminished, or digitally fabricated for people to see, touch, and feel in new ways. Think: whoever starts to talk will be focused and the others around will be blurred in real life.
