Head Eye-K validation dataset

This dataset captures head-eye coordination behaviors in Virtual Reality (VR) and Augmented Reality (AR) environments, recording head and gaze movement trajectories across a variety of experimental tasks. Using a Meta Quest Pro headset with eye and head tracking, we collected yaw, pitch, and roll orientations of both the head and gaze at 90Hz from 16 participants. The dataset includes raw recordings from several conditions: (1) a limit test, where participants attended to 17 evenly spaced targets across a -90° to +90° range; (2) a block-stacking task in passthrough mode; (3) a wack-a-mole VR game involving rapid gaze shifts; and (4) a random condition task, where unpredictable gaze targets required spontaneous head-eye movements. For the random condition task, additional annotations provide target positions over time, allowing analysis of how head-eye coordination adapts to dynamic stimuli. This dataset supports research in gaze-based interaction, head-eye coordination modeling, VR ergonomics, and avatar animation.
