Hello @Corvus,
How to get eye movement data through the SDK?I use the HTC Pro instrument. In the SDK, i found some eye movement data code, but i want to know how to extract it.thank you so much!
public struct SingleEyeData
{
/** The bits containing all validity for this frame.*/
public System.UInt64 eye_data_validata_bit_mask;
/** The point in the eye from which the gaze ray originates in meter miles.(right-handed coordinate system)*/
public Vector3 gaze_origin_mm;
/** The normalized gaze direction of the eye in [0,1].(right-handed coordinate system)*/
public Vector3 gaze_direction_normalized;
/** The diameter of the pupil in meter miles*/
public float pupil_diameter_mm;
/** A value representing how open the eye is.*/
public float eye_openness;
/** The normalized position of a pupil in [0,1]*/
public Vector2 pupil_position_in_sensor_area;
public bool GetValidity(SingleEyeDataValidity validity)
{
return (eye_data_validata_bit_mask & (ulong)(1 << (int)validity)) > 0;
}
}
