PORTABLE TERMINAL DEVICE, CHARACTER CONVERSION DEVICE, CHARACTER CONVERSION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To achieve efficient key operation by the use of a selection key and a character input key when an input character is converted to data including Chinese characters or the like.

SOLUTION: A character conversion device has a table that associates a character assigned on the basis of how many times the character input key is pressed with the number of presses, and a conversion database that associates the character with a conversion candidate converted from the character. When a character is input by the character input key, a plurality of conversion candidates are predicted and retrieved on the basis of the character, using the database. The table is used for determining the number of times that the character input key is pressed for inputting the character following the already input character among unconverted characters corresponding to the conversion candidates, to determine screen display order of the conversion candidates in descending order of the determined number of presses of the character input key. The conversion candidates are displayed on the screen in the screen display order. One of the conversion candidates displayed on the screen is fixed by an enter key.
