Constructors

GazeProvider()

Properties

Enabled	Enable or disable the Component attached to the GameObjectReference
GameObjectReference	Get the GameObject reference for this Gaze Provider.
GazeCursor	The Gaze Cursor for the provider.
GazeCursorPrefab	The prefab to be instantiated as the gaze cursor.
GazeDirection	Normal of the gaze.
GazeInputSource	The Gaze Input Source for the provider.
GazeOrigin	Origin of the gaze.
GazePointer	The Gaze Pointer for the provider.
GazeTarget	The game object that is currently being gazed at, if any.
HeadMovementDirection	The current head movement direction.
HeadVelocity	The current head velocity.
HitInfo	HitInfo property gives access to information at the object being gazed at, if any.
HitNormal	Normal of the point at which the gaze manager hit an object. If no object is currently being hit, this will return the previous normal.
HitPosition	Position at which the gaze manager hit an object. If no object is currently being hit, this will use the last hit distance.
IsEyeCalibrationValid	Whether the user is eye calibrated. It returns 'null', if the value has not yet received data from the eye tracking system.
IsEyeTrackingDataValid	Whether eye tracking data is available. It may be unavailable due to timeout or lack of tracking hardware or permissions.
IsEyeTrackingEnabled	If true, eye-based tracking will be used when available. This field does not control whether eye tracking data is provided.
IsEyeTrackingEnabledAndValid	Whether eye tracking data is currently been used for gaze rather then head pose. Eye Tracking must be both enabled and have valid data.
LatestEyeGaze	The most recent eye tracking ray
overrideHeadForward
overrideHeadPosition
Timestamp	DateTime in UTC when the signal was last updated.
UseHeadGazeOverride	If true, platform-specific head gaze override is used, when available. Otherwise, the center of the camera frame is used by default.

Methods

EnsureInputSystemValid()	A task that will only complete when the input system has in a valid state. (Inherited from InputSystemGlobalHandlerListener)
OnDisable()	UnityEngine.MonoBehaviour.OnDisable
OnEnable()	UnityEngine.MonoBehaviour.OnEnable
OnInputDown(InputEventData)
OnInputUp(InputEventData)
OverrideHeadGaze(Vector3, Vector3)	Allows head gaze to be overridden, typically by platform-specific values.
RegisterHandlers()	Overload this method to specify, which global events component wants to listen to. Use RegisterHandler API of InputSystem
SetGazeCursor(GameObject)	Set the gaze cursor.
Start()	UnityEngine.MonoBehaviour.Start
UnregisterHandlers()	Overload this method to specify, which global events component should stop listening to. Use UnregisterHandler API of InputSystem
UpdateEyeGaze(IMixedRealityEyeGazeDataProvider, Ray, DateTime)	Tells the eye gaze provider that eye gaze has updated.
UpdateEyeTrackingStatus(IMixedRealityEyeGazeDataProvider, Boolean)	Tells the eye gaze provider about the eye tracking status (e.g., whether the user is calibrated);
UpdateGazeInfoFromHit(MixedRealityRaycastHit)	Notifies this gaze provider of its new hit details.
