Report B
Charts
Visual comparison of runtime cost and FPS sampling effects. Series colours: Report A in Totum blue, Report B in slate (unless noted).
Runtime / device
R1 · Wall-clock breakdown
R2 · Processing time
R3 · Time per frame
R4 · Peak RSS
R5 · Realtime factor
Video duration ÷ processing (≥1 is faster than realtime).
Accuracy / FPS sampling
A1 · Movement share
A2 · Bimanual activity
A3 · Frames analysed
A4 · Metric ratios (B ÷ A)
How many times larger Report B is vs A for key motion metrics.
Per-hand metrics
M1 · Path length (px)
M2 · Movement count
M3 · Visibility %
M4 · Idle %
M5 · Working-area %
M6 · Out-of-view events
M7 · Smoothness LDLJ
Not directly comparable across different sampling rates.
Dwell quality
D1 · Dwell counts
D2 · Dwell composition
Exact 1.0s dwells nested in totals (false-positive signal at 1 FPS).
D3 · Dwell duration histogram
Spatial
S1 · Dwell positions
Point size scales with dwell duration. Frame coordinates in pixels.
