Hidden In Plain Gaze: Gaze Representations as Privacy Controls for Utility and Re-identification Risk in XR
arXiv
Single-dataset empirical study of a design intervention (gaze representation choice) on privacy-utility tradeoff in XR, with no peer review, no randomization, and no comparison to established baselines or formal privacy guarantees.
Reported
Action recognition accuracy reten…roughly 85%
Re-identification risk reduction…about an order of magnitude
Re-identification accuracy (engin…roughly four times the chance rate
