The project has two main components: X-Motion, a real-time interactive system for live performances; and Choreographisms, an interface abstraction for graphical interpretation of motion-paths. This framework is demonstrated through an experiment that includes a choreography of the artist-collaborator for the piece Unsquare Dance.Categories and Subject Descriptors (according to ACM CCS): I.3.8 [Computer Graphics]: Applications
