Hand-Object Interaction

The full range of physical actions people perform when grasping, touching, holding, manipulating, or gesturing toward objects with their hands. In accessibility research, hand-object interactions are studied as natural intent cues that can drive assistive technology: for blind and low vision users, holding, touching, pointing, or comparing objects side-by-side reveals what the user wants to learn about, allowing camera-based systems to deliver targeted visual descriptions without requiring deliberate photo capture or verbal commands. Recognizing hand-object interactions reliably typically combines hand pose estimation, gesture classification, and contact detection.
