A Virtual Reality Dataset to Support Hand Action Observation in Rehabilitation and Motor Learning Studies (v1.0)

This deposit contains the UpperLimbAOT-VR dataset and Unity® 6000.0.24f1 project, comprising: (1) the full Unity project directory, (2) a pre-compiled Android APK for Meta Quest headsets, (3) a QuickStart Guide PDF, and (4) a README with usage notes. The dataset includes 132 VR scenes (allocentric/egocentric, left/right limbs), high-definition instructional videos, and two custom playback methods: the CustomScene manager for arbitrary sequences, and the ControlScene interface (the APK’s default launch scene) which provides dropdown and slider controls to configure stimulus order, side choice to train, difficulty, viewpoint, and repetition count. Designed for upper-limb rehabilitation and motor-learning research, this package enables immediate deployment on Meta Quest devices or in-editor testing with Quest Link.
