Flow Tree: A Dynamical Classifier for Quantifying Navigation Paths and Strategies

Bertics, A., Chrastil, E., Miolane, N., & Carlson, J.

We introduce the Flow Tree, a novel data structure adapted from the Reeb graph, to capture and analyze dynamic navigation behaviors across multiple trajectories, enabling improved prediction of path difficulty and individual navigation success. Applied to VR maze data from 100 participants, Flow Trees outperform static metrics and reveal distinct strategies used by good versus poor navigators.
