RobertsonLab Posted July 1, 2019 Share Posted July 1, 2019 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! ( - tag added by moderator) Link to comment Share on other sites More sharing options...

RobertsonLab Posted July 8, 2019 Author Share Posted July 8, 2019 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?

Daniel_Y Posted July 9, 2019 Share Posted July 9, 2019 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 */ }; Link to comment Share on other sites More sharing options...
