- Abstract
Recently, a method to discriminate the gazing point using the counter-reflex has been proposed. We investigated the validity of the above model, which assumes that the pupil response is determined by the input light stimulus to the left and right eyes. The results of experiments in which the luminance of the input to the left eye was fixed and the luminance of the input to the right eye was randomly varied were not consistent with the above model. We also conducted an experiment to compare the difference in pupil response between the left and right eyes by changing the ratio of the input to the left and right eye. The pupil response was greatest when the same light stimulus was input to both eyes, suggesting that changing the luminance value of the light stimulus for the left and right eyes may not be suitable for a pupil-measuring interface.
