A multimodal biomechanical and eye-tracking dataset of suprapostural coordination in healthy young adults

This dataset provides annotated full-body kinematics, gaze tracking, and ground reaction forces and moments from 48 healthy young adults performing life-size suprapostural tasks. Using a 12-camera motion capture system, an eye tracker, and a force plate, participants completed four tasks: standing upright and performing the Trail Making Test (TMT) Part-A projected on a screen, both on a stable surface and a mediolaterally oriented wobble board inducing instability. Each trial lasted five minutes, capturing TMT trajectories, performance scores, video recordings, full-body kinematics, center of mass (CoM), joint angles, eye gaze and pupil diameter, ground reaction forces and moments, and the center of pressure (CoP). This multimodal dataset offers a unique opportunity to explore balance, motor control, and cognitive performance during concurrent tasks.
