QTM processed eye tracking data, suitable for 3D programming

Fields

eyesTracked: bool

< Eye position detected or tracked with some confidence, equals (confidenceLevel > 0). Even if false, QTM may make a guess

faceDetected: bool

< Whether or not the entirety of the user’s face has been detected with good confidence.

eyesDetected: bool

< Whether or not the user’s eyes have actually been detected with full confidence.

_unused: u8_

< Unused.

clamped: bool

< Whether or not the normalized eye coordinates have been clamped after accounting for lens distortion.

_padding: [u8_; 3]

< Padding.

confidenceLevel: f32

< Eye tracking confidence level (0 to 1).

eyeCameraCoordinates: [[f32; 2]; 2]

Normalized eye coordinates, for each eye, after accounting for lens distortion, centered around camera. X coord is in the -1 to 1 range, and Y coord range depends on inverse aspect ratio (-0.75 to 0.75 on real hardware).

Note: On real hardware, X coord equals ((rawX / 160.0) - 1.00) * 1.0639 before clamping. Note: On real hardware, Y coord equals ((rawY / 160.0) - 0.75) * 1.0637 before clamping.

eyeWorldCoordinates: [[f32; 2]; 2]

Normalized eye coordinates, for each eye, in world space. Corresponds to eyeCameraCoordinates multiplied by tangent of field of view.

Note: On real hardware, X coord equals eyeCameraCoordinates.x * tan(64.9 deg / 2). Note: On real hardware, Y coord equals eyeCameraCoordinates.x * tan(51.0 deg / 2).

dPitch: f32

< Difference in gyro pitch from position at console boot.

dYaw: f32

< Difference in gyro yaw from position at console boot.

dRoll: f32

< Difference in gyro roll from position at console boot.

samplingTick: s64

< Time point the current measurements were made.
