AR-Rehab: Raw per-session logs for occlusion-resilient mixed reality upper-limb rehabilitation

Raw per-session logs from an occlusion-resilient visuo-inertial smart-object system for upper-limb rehabilitation, recorded with instrumented therapeutic cubes and a Meta Quest 3 headset during a preliminary six-participant feasibility study at the Hospital Nacional de Parapléjicos (Toledo, Spain). Each session directory contains synchronized CSV streams: smart-object inertial and grip-pressure telemetry, YOLOv8-Pose visual detections with keypoint coordinates, fused 6-DoF pose estimates, per-frame cube state with tracking source and contact level, participant head and hand kinematics, automatically segmented interaction episodes, serious-game events, and yaw-calibration records. Participant data are anonymised.
