Abstract

A novel information processing device that is highly convenient is provided. The information processing device includes a selection circuit having a function of supplying image data to a reflective display element, a light-emitting element, or both of them on the basis of input position coordinate data, sensing data about the illuminance of the usage environment, and the image data. An icon with high selection frequency is displayed by both the reflective display element and the light-emitting element on the basis of icon coordinate data and the input position coordinate data, so that the icon can be displayed brightly with improved visibility.
