In this panel, we explore the role emerging transitive materials, like flexible thin-film displays, multi-touch input skins, e-textiles, micro-actuators and Claytronics might play in re-defining the human interface towards a programmable form of reality. Panelist will extrapolate historical trends from Tangibles to new developments in organic user interfaces, trying to identify a future in which interfaces will no longer be predominantly flat, but instead have any possible shape or form: from skins that are foldable, flexible and physical to three-dimensional products that are fully kinetic. Keywords Organic User Interface, Transitive Materials, Tangible User Interface, Programming Reality. ACM Classification Keywords H5.m. Information interfaces and presentation
