About this view +
Each point is one of 14,861 updates from participant 1. SPAR token IDs are replaced with their codebook vectors across 320 electrodes. Lagged updates, sampled every 120 ms, supply the selected history. The animation follows phase-aligned mean trajectories through the saved embedding.
The three-dimensional UMAP is projected onto a separate mean-trajectory plane for each movement, and the groups are positioned separately. Each history setting has its own fitted view; changing history does not track points through a common coordinate system. The curves average 20 phase bins across complete repetitions and use a periodic spline to join their endpoints. The moving markers show normalized repetition phase, with playback slowed to eight seconds.
