Movement + force estimate

Experimental
Jump height—flight-time method
Flight time—take-off → landing
Take-off velocity—from flight height
CM depth—hip-COM proxy
Time to take-off—movement start → take-off
Peak est. vGRF—before take-off
Experimental force estimate. Total vertical GRF is estimated from pose-derived COM acceleration and body mass. The two arrows show the current estimated left/right GRF as an illustrative 50/50 split of the total curve while both feet are in contact. They are not validated left/right force estimates. Validation and calibration are future work.
