Abstract
Abstract © A character input apparatus has a position input device (11) for inputting coordinate values corresponding to a position indicated by contacting an input surface, a recognition processor (42) for analyzing a coordinate value string sequentially input by the position input device (11) to obtain a character code corresponding thereto, and a display device (14) for displaying the character code obtained by the recognition processor (42). The character input apparatus includes a character size processor (43) for discriminating a distribution range of the coordinate value string to obtain character size data corresponding to the size of the distribution range. A character is displayed on the display device (14) in a character size corresponding to the character size data obtained by the character size processor (43).
