LINEAR
"LINEAR allows, with some limitations, the representation of gestural movements with an exact 3-D placement in space: we can now have an analogic notation of gestures, rather than a symbolic one. For the iPhone performer, the act of notation corresponds to the notated act.
The resulting representations can be also interpreted as a form of graphic animated notation by other performers (the iPhone screen is mirrored to a projector). The multiperspectivity of the notation and the possibilities of interaction with virtual bodies allow a high level of flexibility and foresee a potentially very rich scenario."
