Operating device and operating method

Abstract

When a user's finger is pressed on a fingerprint reading region in which fingerprint information of the user's finger is read, a user authentication unit (201) reads the fingerprint information of the user's finger and determines whether or not the read fingerprint information matches registered fingerprint information that is registered in advance. If the read fingerprint information matches the registered fingerprint information, an icon acquisition unit (202) acquires icons indicating functions that can be used by the user of the read fingerprint information. If the press by the user's finger is continued, an icon switching unit (203) switches, every predetermined switching time, the acquired icons for display in the vicinity of the user's finger in the order in which the icons are acquired. If the press by the user's finger is released while the icons are switched for display, a function transition unit (205) transitions to the function of the icon displayed at the time when the press by the user's finger is released.
