Abstract

It is well known that pupil size measurement is influenced by noises and blinks. This paper describes the development of an estimation model for the pupil size of blink artifacts. The development of the model was based on a three-layered perceptron, using a backpropagation method. First, the model was trained using pupil responses to changes in brightness, after which the model could estimate pupil temporal changes. Second, the model was trained using pupil responses with artificial blinks. The model could also estimate pupillary changes and pupil size during blinks. The model was applied to pupillary changes during TV program viewing. The accuracy of removing the influence of brightness was evaluated using one-way ANOVA. The pupil size sampling rate was improved from 3 to 30 Hz using the processing model.
