Abstract-The Laban Effort and Shape components provide a systematic tool for a compact and informative description of the dynamic qualities of movements. To enable the application of Laban notation in computational movement analysis, measurable physical correlates of Effort and Shape components need to be identified. Such physical correlates enable quantification of Effort and Shape components, which in turn facilitates computational analysis of affective movements. In this work, two existing approaches to quantification of Laban Effort components (Weight, Time, Space, and Flow) based on measurable movement features (position, velocity, acceleration, and jerk) are adapted for hand and arm movements, and a new approach for quantifying Shape Directional based on the average trajectory curvature is proposed. The results show a high correlation between Laban annotations provided by a certified movement analyst (CMA) and the quantified Effort Weight (81%), Time (77%) and Shape Directional (93%) for an affective hand and arm movement dataset.
