bool isValid() const#
Returns the current value indicating if eye tracking is valid.
Return value
true if eye tracking is valid; otherwise false.Math::Vec3 getFocusWorldPosition() const#
Returns the current position of the eye focus point in world coordinates.
Return value
Current world position of the eye focus point.Math::vec3 getGazeWorldDirection() const#
Returns the current gaze direction vector, which is a combined value for both eyes, in world coordinates.
Return value
Current direction vector for both eyesMath::Vec3 getLeftEyeWorldPosition() const#
Returns the current position of the left eye in world coordinates.
Return value
Current world position of the left eye.Math::vec3 getLeftEyeWorldDirection() const#
Returns the current direction vector of the left eye in world coordinates.
Return value
Current direction vector of the left eye.float getLeftPupilDiameter() const#
Returns the current estimated diameter of the left pupil. The function returns 0.0f if the pupil is not tracked or the estimate is unavailable.
Return value
Current diameter of the left pupil, in millimeters.getLeftPupilIrisDiameterRatio() const#
Returns the current ratio between the left pupil diameter estimate and the estimated diameter of the left iris. If either estimate is unavailable, preventing the calculation of the ratio, the function returns 0.0f.
Return value
Current ratio of the left pupil diameter estimate to the estimated left iris diameter.float getLeftIrisDiameter() const#
Returns the current an estimated diameter of the left iris. The function returns 0.0f if the estimate is unavailable.
Return value
Current diameter of the left iris, in millimeters.float getLeftOpenness() const#
Returns the current estimated openness ratio of the left eye. 1.0f corresponds to a fully open eye, 0.0f to a fully closed eye.
Return value
Current estimated openness ratio of the left eye in range [0.0f;1.0f].VREyeTracking::EYE_STATUS getLeftStatus() const#
Returns the current status of the left eye.
Return value
Current status of the left eye.float getRightPupilDiameter() const#
Returns the current estimated diameter of the right pupil. The function returns 0.0f if the pupil is not tracked or the estimate is unavailable.
Return value
Current diameter of the right pupil, in millimeters.float getRightPupilIrisDiameterRatio() const#
Returns the current ratio between the right pupil diameter estimate and the estimated diameter of the left iris. If either estimate is unavailable, preventing the calculation of the ratio, the function returns 0.0f.
Return value
Current ratio of the right pupil diameter estimate to the estimated left iris diameter.float getRightIrisDiameter() const#
Returns the current an estimated diameter of the right iris. The function returns 0.0f if the estimate is unavailable.
Return value
Current diameter of the right iris, in millimeters.float getRightOpenness() const#
Returns the current estimated openness ratio of the right eye. 1.0f corresponds to a fully open eye, 0.0f to a fully closed eye.
Return value
Current estimated openness ratio of the right eye in range [0.0f;1.0f].Math::Vec3 getRightEyeWorldPosition() const#
Returns the current position of the right eye in world coordinates.
Return value
Current world position of the right eye.Math::vec3 getRightEyeWorldDirection() const#
Returns the current direction vector of the right eye in world coordinates.
Return value
Current direction vector of the right eye.VREyeTracking::EYE_STATUS getRightStatus() const#
Returns the current status of the right eye.
Return value
Current status of the right eye.float getIPD() const#
Returns the current interpupillary distance (IPD).
Return value
Current interpupillary distance.long long getRawCaptureTime() const#
Returns the current timestamp of when the data was recorded, in nanoseconds.
Return value
Current timestamp of when the data was recorded, in nanoseconds.double getFocusDistance() const#
Returns the current distance between the eye and the focus point. It is a value between 0 and 2> meters.
Return value
Current distance between the eye and the focus point.double getStability() const#
Returns the current value specifying the stability of the user’s focus. 0.0 means not stable and 1.0 means stable.
Return value
Current stability of the user’s focus in range [0.0;1.0].VREyeTracking::STATUS getStatus() const#
Returns the current value representing the status of eye tracking in the Varjo headsets.
Return value
Current value representing the status of eye tracking.long long getRawFrame() const#
Returns the current unique identifier of the frame when the data was recorded.
Return value
Current unique identifier of the frame when the data was recorded.void setVisualizerEnabled ( bool enabled ) #
Sets a new value indicating if the visualizer is enabled.
Arguments
- bool enabled - Set true to enable the visualizer; false - to disable it.
bool isVisualizerEnabled() const#
Returns the current value indicating if the visualizer is enabled.
Return value
true if the visualizer is enabled; otherwise false.void requestCalibration ( ) #
Triggers the gaze calibration sequence, if gaze tracking has been enabled in Varjo settings and the Varjo system is in a state where it can bring up the calibration UI.Last update:
