the shape of movement / paired filaments
Each pair of filaments represents one local date from one recording source. Blue rises with the median walking speed; yellow descends with median stride length. Only measurements sharing the same source, start and end time enter either median. One unmatched speed measurement is excluded from this retained export. These are sample medians, not duration-weighted summaries.
Vertical extension is linear from zero to the full archive maximum for each measure, in separate units. Sources occupy separate passages; dates advance left to right within each passage in observed-date order. Filament width, curvature and seam undulation are composition. They do not reconstruct a walk. Filtering keeps positions and scales fixed. Missing dates are omitted, and no filament connects across sources or dates.
The archive source labels G1, G2 and G3 are anonymous recording-source groups. They are not assumed to be independent instruments or people. A source change may reflect a different phone. This form describes recorded movement, not mood or an episode.
Click near a filament seam to select a source/date. Focus the artwork and use left/right to inspect observations chronologically, Home/End for the first/last, or Enter to open this reader. The date control selects the nearest available date in the chosen source.
