Head-EyeK: Head-Eye Coordination and Control Learned in Virtual Reality
Bibliographic record
Abstract
Human head-eye coordination is a complex behavior, shaped by physiological constraints, psychological context, and gaze intent. Current context-specific gaze models in both psychology and graphics fail to produce plausible head-eye coordination for general patterns of human gaze behavior. In this paper, we: 1) propose and validate an experimental protocol to collect head-eye motion data during sequential look-at tasks in Virtual Reality; 2) identify factors influencing head-eye coordination using this data; and 3) introduce a head-eye coordinated Inverse Kinematic gaze model Head-EyeK that integrates these insights. Our evaluation of Head-EyeK is three-fold: we show the impact of algorithmic parameters on gaze behavior; we show a favorable comparison to prior art both quantitatively against ground-truth data, and qualitatively using a perceptual study; and we show multiple scenarios of complex gaze behavior credibly animated using Head-EyeK.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
