摘要

A display apparatus (100) includes: a display (131) having a screen in which an image is displayed; an input unit (132) having a surface on which a user's touch is sensed; a display controller that displays a plurality of individual icons and one or more category icons each of which represents a category of one or more individual icons; and a motion recognition unit (112) that detects a pinching-out motion to widen a distance between two points of touch on the surface based on a motion sensed by the input unit, wherein the display controller changes a state of one or more individual icons associated with at least one category from an enfolded state in which the one or more individual icons are not displayed to an unfolded state in which the one or more individual icons are displayed.
