摘要

An information processing apparatus includes: a storage unit storing content data and first group identification information for identifying first groups in which the content data are arranged in a predetermined unit; a parameter output unit outputting a parameter representing an amount of displacement of an operating object in response to an operation on the operating object which can be displaced in a predetermined range by a user's operation; a selection unit sequentially selecting the content data while the parameter is in a first range and sequentially selecting the first groups by sequentially selecting the first group identification information stored in the storage unit while the parameter is a value in a second range; and a notification unit notifying what content data is selected when the content data are selected by the selection unit and notifying what group is selected when the first groups are selected by the selection unit.
