Detailed Description

ValidationPointResult holds the results of the validation ( total deviation between true point position and calculated POR of the left and right eye POR in [px] and [deg] ) of the validation point at position ( validationPointPxX, validationPointPxY ) [px].

The stimulus point position and deviation [px] are given in the 2D stimulus coordinate system originating in the top left corner of the stimulus.

The deviation [deg] corresponds to the total angular deviation between the measured gaze direction from the ground truth gaze direction as determined according to the measured eye position.

Note: All data fields may be ELInvalidValue. All pairs validationPointPxX/-Y, meanDeviationLeftDeg/-Px and meanDeviationRightDeg-/Px are always either both valid or both ELInvalidValue.
