ECHO: Ego-Centric modeling of Human-Object interactions
arXiv CS.CV

ArXi:2508.21556v2 Announce Type: replace Modeling human-object interactions (HOI) from an egocentric perspective is a critical yet challenging task, particularly when relying on sparse signals from wearable devices like smart glasses and watches. We present ECHO, the first unified framework to jointly recover human pose, object motion, and contact dynamics solely from head and wrist tracking. To tackle the underconstrained nature of this problem, we
