Eye Confidence

Recommended Posts

Hi all,

 

We were wondering if there is a measure of how confidence output by the tracking system, meaning how confident the algorithm can say what it is detecting is a pupil?

 

Thank you!

Is there a breakdown to what is deemed "invalid"? Is this based on pupil detection, meaning is a sample considered invalid if the software cannot confidently determine the pupil?

A eye_data_validata_bit_mask defined in struct SingleEyeData to indicate which data's validness listed below. Usually, the data becomes invalid when eye closed.

 

enum SingleEyeDataValidity {

SINGLE_EYE_DATA_GAZE_ORIGIN_VALIDITY,/*!<The validity of the origin of gaze of the eye data */

SINGLE_EYE_DATA_GAZE_DIRECTION_VALIDITY,/*!<The validity of the direction of gaze of the eye data */

SINGLE_EYE_DATA_PUPIL_DIAMETER_VALIDITY,/*!<The validity of the diameter of gaze of the eye data */

SINGLE_EYE_DATA_EYE_OPENNESS_VALIDITY,/*!<The validity of the openness of the eye data */

SINGLE_EYE_DATA_PUPIL_POSITION_IN_SENSOR_AREA_VALIDITY/*!<The validity of normalized position of pupil */

};
