Public Attributes Documentation
version
uint32_t version;
Version of this structure.
timestamp
MLTime timestamp;
The timestamp accociated with all data fields in this struct.
error
MLGazeRecognitionError error;
| Type | Description |
|---|---|
| MLGazeRecognitionError | A set of possible error codes that the Gaze Recognition system can report. |
Represents what gaze Recognition error (if any) is present.
behavior
MLGazeRecognitionBehavior behavior;
| Type | Description |
|---|---|
| MLGazeRecognitionBehavior | A set of mutually-exclusive behaviors that the Gaze Recognition system can report. |
Represents what known gaze Recognition behavior is present.
eye_left
MLVec2f eye_left;
A vector for eye-in-skull position of left eye, even if right eye is closed.
eye_right
MLVec2f eye_right;
A vector for eye-in-skull position of right eye, even if left eye is closed.
onset_s
float onset_s;
Metadata field for onset of the current behavior, in seconds. Onset applies to all behaviors and marks the time when the current behavior began.
duration_s
float duration_s;
Metadata field for duration of the current behavior, in seconds. Duration applies to all gaze types.
velocity_degps
float velocity_degps;
Metadata field for velocity of the current movement, in degrees per second. Velocity field applies to saccades and pursuit, otherwise NaN.
amplitude_deg
float amplitude_deg;
Metadata field for amplitude of the current movement, which is eye-position displacement in degrees of visual angle. Amplitude applies to saccades and pursuit, otherwise NaN.
direction_radial
float direction_radial;
Metadata field for direction of the current movement, in radial degrees (0-360). Direction field applies to saccades and pursuit, otherwise NaN.
