The present invention provides effective information search means, and/or effective acquired information submission means, without overtly expressing an intent (e.g., through the depression of a search button) to acquire information. In an example embodiment, the kana-kanji conversion routine is activated, and a character string is input using voice, a keyboard or a graphic entry process. Then, a conversion key is depressed to convert the input character string into kanji. Upon the depression of the conversion key, the homonym candidate selection routine is initiated, and the conversion candidate is presented. In response to the depression of the conversion key, or the change of the conversion candidate in the homonym candidate selection routine, the information access routine is activated. Then, the information access procedure is performed, and the search results are acquired. Thereafter, the search results are presented.
