The PInSoRo Dataset (also called Freeplay Sandbox dataset) is a large (120 children, 45h+ of RGB-D video recordings), open-data dataset of chid-child and child-robot social interactions.
These interactions are recorded during little-constrained free play episodes. They emcompass a rich and diverse set of social behaviours.
The dataset is publicly available to interested academics (with some restrictions). See the details here.
