Research questionHow should gaze representations balance XR task utility against biometric identity leakage?Eye and head tracking can support task recognition while retaining patterns that identify users. Representation choices affect both properties, and attenuating identity information does not necessarily remove it.

Latest papersRecent research connected to this question, newest first.Hidden In Plain Gaze: Gaze Representations as Privacy Controls for Utility and Re-identification Risk in XRThe source compares raw gaze, spatial attention heatmaps, and engineered eye-movement features with matched-capacity models on the egocentric HoloAssist dataset. It evaluates action recognition and closed-set user re-identification, providing evidence about representation-level leakage reduction rather than formal privacy guarantees or behavior beyond the tested tasks and population.research paper · Sep 4, 2026
