Title: Method for displaying roman character
Inventor: FURUYA NAOHITO
IPC: G06F17/22
Filed: 2000-09-05
Abstract: PROBLEM TO BE SOLVED: To facilitate the recognition of the reading of Roman characters in the case of converting a plurality of Kana (Japanese syllabary) characters into the Roman characters and displaying the Roman characters. SOLUTION: When, for instance, a 'Nissan security service' in Kana characters is displayed in Roman characters, the 'Nissan security service' is displayed while a space or a delimiter such as a hyphen is inserted between sounds. In such a case, a prolonged sound is obtained by overlapping the vowel of a Roman character at the time when a Kana character previous by one character is converted, and a syllabic nasal is obtained by overlapping the consonant of a Roman character at the time when the next character is converted. Thus, because a sound can be recognized by one character at a time even though a user is unfamiliar with Roman characters, a sound represented by a character string is easy to understand, a Roman character string is easy to read and the contents of the Roman character string can easily be recognized.
