Researchers have developed HOPE, a novel framework for estimating physical pressure from monocular videos, addressing limitations of previous methods that were restricted to planar surfaces and single images. HOPE formulates pressure estimation as a hand-centric video prediction problem, outputting temporally evolving per-vertex normal pressure and contact directly on a hand mesh. The framework integrates various pressure and contact annotations, including tactile-glove and planar-sensor data, to regularize learning, even where metric labels are unavailable. A key component is a vertex-anchored video transformer that aggregates visual and pose features over time, with a contact-gated head ensuring pressure vanishes without contact. Experiments on benchmarks like OpenTouch and PressureVisionDB demonstrate HOPE's ability to generalize to bare-hand videos and predict joint contact and pressure. AI
