A collection of nearly 8,000 densely annotated images of hands, captured from visitors to the Augmented Hand Series interactive installation by Golan Levin, Christine Sugrue, and Kyle McDonald. The images were collected at public exhibitions in the Netherlands and Germany in 2014 and 2017, and represent a varied sample of festival and museum visitors, including many children and families. Most images show right hands, freely posed with palms facing downward. Each image is accompanied by a dense, triangulated 2D hand mesh with consistent anatomical vertex correspondence across the entire dataset, along with XML metadata describing hand landmarks, finger dimensions, and other geometric properties.
