| Abstract(in English) | It is well known that pupil size measuring is influenced by pupillary noise and blink. This paper describes a development of smoothing and prediction model of pupil size for blink artifact. The model development was based on 3 layered perceptron with backpropagation method. First, the model was trained by pupil response to brightness change, and the model could smooth down the pupil temporal changes. Second, the model was trained by pupil response with artificial blinks. The model could also smooth down the pupillary changes, and predict pupil size while blinks. The model was applied to pupillary changes in watching TV program. The performance of removing brightness influence was evaluated one-way ANOVA. The sampling rate for pupil size could be improved to 10Hz from 3Hz by using the model processing. |
