ABSTRACT:
The present invention provides a handwritten character input device and handwritten input character processing method enabling easy selection of a text input area and reliable input of handwritten characters, regardless of where the text input area is located. The handwritten character input device comprises a text input area setting unit for setting a text input area, a writing trace input unit for detecting a moving trace of a pointing device, a stroke condition judgment unit for judging whether the first or last stroke of the moving trace of the pointing device detected by the writing trace input unit satisfies a prescribed condition, an input area selection unit for selecting a text input area as a transmission destination of the character string information based on the judgment results of the stroke condition judgment unit, a writing trace processing unit for recognizing the character string information from the writing trace defined by the moving trace of the pointing device input by the trace input unit excluding the strokes judged by the stroke condition judgment unit to satisfy the prescribed condition, and a processing result transmission unit for transmitting the character string information recognized by the writing trace processing unit to the text input area selected by the input selection unit.
