Embodiment Construction

[0023] Since the handwritten Chinese character input recognition can be realized by various methods well known in the art, and conventional systems or software can be used for recognition, for the sake of simplicity, the recognition process itself will not be described in detail here.

[0024] Referring first to Figure 1, where Figure 1A It schematically illustrates possible misrecognition in the prior art handwritten Chinese character input recognition method using timeout for recognition. like Figure 1A As shown, the user intends to write a left-right type character "Ming" consisting of two parts. He usually writes the "day" on the left first, and then the "month" on the right. Since "Ming" is composed of two parts, the radical "日" and a "month" that can independently form a character, he needs to move from the last stroke of the left half "日" (the middle lower part of the input / writing area) A long distance to the first stroke of the "month" in the right half (the upper ...

Abstract

The invention relates to an improved identification device for handwritten Chinese character input and an improved identification method for the handwritten Chinese character input, and the device and the method are used for an electronic device. The improved identification device for the handwritten Chinese character input comprises a device used to indentify a Chinese character which is written in a writing area of the electronic device by a user, but the identification is finished only when the following requirements are met. The requirements include that a start point or a middle point of a previous stroke is not in a scheduled start area, previous several strokes constitute a complete character, and a start point or a middle point of a current stroke is in the start area.

Description

[0001] This application is a divisional application with application number 200310115725.7, application date November 28, 2003, and titled "Improved Handwritten Chinese Character Input Recognition Method". technical field [0002] The present invention relates to handwritten Chinese character input recognition, in particular to an improved handwritten Chinese character input recognition method for electronic devices, which can tolerate timeout or even not be affected by timeout, and can allow partial modification of inputted characters. Background technique [0003] Handwritten Chinese character input is a commonly used input method for computers and other electronic devices with touch screens or touch pads (writing pads). With the wide application of notebook computers, mobile phones and personal data assistants (PDAs), fast, efficient and accurate handwritten Chinese character input recognition has become the wish of many people. [0004] For writing Chinese characters, di...
