Detailed Description

QTM raw eye tracking data.

Field Documentation

eyesTracked

bool QtmRawTrackingData::eyesTracked

Eye position detected or predicted, equals (confidenceLevel > 0).

If false, QTM will attempt to make a guess based on gyro data. If the console isn't moving either, then QTM will assume the user's eyes are progressively moving back to face the screen. Eye position detected or predicted, equals (confidenceLevel > 0).

rawEyeCameraCoordinates

float QtmRawTrackingData::rawEyeCameraCoordinates[QTM_EYE_NUM][2]

Raw predicted or detected eye coordinates.

Each eye is represented as one point. Fractional part is not necessarily zero.

Note

X coord is within 0 to 320.

Y coord is within 0 to 240.
