Abstract
A hand-held computer with an input pen capable of handwriting recognition. Characters are inputted by a user's manual operation with the input pen on a transparent coordinate input plate in front of a display screen. The computer discriminates pen-input characteristic of the user, and selects a character-recognition dictionary based on the discrimination result.
