Enum VarjoEyeTrackingHandler.GazeDataSource
Selects which Varjo API path to use for raw gaze vectors.
public enum VarjoEyeTrackingHandler.GazeDataSource
Fields
| Name | Type | Description |
|---|---|---|
GazeAPI = 1 | Varjo native API — additionally exposes pupil and iris diameter per eye for cognitive-load analysis via pupillometry. | |
InputSubsystem = 0 | Standard OpenXR path — returns fixation point and eye poses but no pupillometry. |
Remarks
InputSubsystem follows the OpenXR standard and is portable but only exposes a combined fixation point. GazeAPI is Varjo-proprietary and additionally provides per-eye pupil and iris diameter in millimetres, required for pupillometry analysis. Use GazeAPI unless the headset model does not support the Varjo native SDK.
