MotionFlow for pattern analysis of human motion data. (a) Pose tree: a simplified representation of multiple motion sequences
aggregating the same transitions into a tree diagram. (b) A window dedicated to show a subtree structure based on a query. (c)
Space-filling treemap representation of the motion sequence data using slice-and-dice layout. (d) Node-link diagram of pose
clusters (nodes) and transitions (links) between them. This view supports interactive partition-based pose clustering. (e) Multi-tab
interface for storing unique motion patterns. (f) Animations of single or multiple selected human motions.
