LABANotationLABANotationA two-dimensional graphic notational system for recording movement of the human body.Rudolf Laban originated it.It was first published on 1928.Its main application is the recording of ballet/modern dance, physical therapy, and drama.There are three essential forms of movement description in LABANotation: Motif, Effort-Shape and Structural.

Matching Movement ChallengesMatching Movement ChallengesGoal: Compare user’s movements (UM) with a
model (LM) specified using LABANotation for analysis/diagnosis or alert/guidance. But this comparison implies two constrains: time and space. How to line them up?Each person is unique in term body size/shapeHow to calibrate or convert to a canonical formExpecting a delay between the start of LM simulation, and the start of UM simulationHow to identify when the user begins his movements, and when he ends them?
