GigaHands: A Massive Annotated Dataset of Bimanual Hand Activities

Strum the ukelele strings with your right hand Deliver the fry to your mouth. Intersect your fingers and pull gently to stretch. Give a thumbs-up gesture. Figure 1. GigaHands is a massive dataset of human bimanual activities with paired text annotations. Each column above shows an activity sequence from the dataset. The dataset covers diverse 3D hand activities, including hand-object interactions (blue) across object scales, gestures (orange), and self-interactions (red). Each clip is paired with descriptive text and 51 camera views, enabling radiance field reconstruction. The bottom row show other annotations in the dataset including hand shape, object shape and pose (left half images). The right half images show novel views from dynamic radiance field fitting.
