Abstract

An apparatus includes a context information extracting part that monitors a state of the apparatus and extracts context information indicative of the state; a note information saving part that saves note information in association with context information when the note information for displaying is registered; a context information similarity evaluating part that determines, for each piece of the note information, similarity between the context information extracted by the context information extracting part at a certain point in time and context information which is associated with note information saved by the note information saving part; and a note information display part that displays the note information saved in the note information saving part in a display mode in accordance with the determined similarity of the note information.
