Determine whether improved extremity estimates benefit world-space motion and foot-ground contact

Determine whether the improved extremity estimates produced by ExMR benefit world-space human-motion recovery and consistency between reconstructed feet and the ground.

Background

ExMR is quantitatively evaluated primarily for camera-frame reconstruction, although its architecture retains a world-grounded recovery path. The paper does not establish whether its improved hand and foot estimates translate into better world-space motion or more consistent foot–ground interactions. The authors identify this relationship as a direction for further investigation.
