Channels (13) · dot = isolate · name = open in explorer ↗
Muscle glow = EMG activation 0→1, peak-normalized per muscle (timing, not force)
Ivory = bone (Anatomical) · thin gray lines = 226 muscles without EMG
Green arrow = vertical GRF · scale: 1 ×BW = 0.52 m (reference arrow beside the figure)
Biomech: blue = moment, 1 Nm/kg = 0.5 m · red = angular velocity, 10°/%GC = 0.28 m · sphere = power, green + / purple − (W/kg)
Cyan = hip-exo overlay · geometry only, follows the hip angle; no force data
Scrub bar: stance / swing, HS & TO ticks · level walk starts at ipsilateral heel strike; stairs/ramps/sit-to-stand use the source's start event
Dataset badge: ● measured in selected set · ● filled from largest set (blue on body too) · ○ faded = no EMG
ⓘ what is data-driven, and what is not
Each channel is scaled to its own peak — color shows activation timing within a muscle, not effort between muscles (amplitude is not comparable without MVC). Blue / desaturated muscles on the body are cross-dataset fills, not measured here. Left & right are assumed symmetric (contralateral limb mirrored; the lit/HUD leg is the left).
The legs’ hip / knee / ankle sagittal motion is driven frame-by-frame by our harmonized cross-dataset angle curves. Arm-swing, trunk & pelvis come from a fixed walk.bvh mocap template (MotionBuilder Character1), not from harmonized data. The hip-exo overlay is geometry that follows the hip angle; no assist force is measured or shown.
