Description

Portable electronic device with writing teaching function

technical field

The invention relates to a portable electronic device, in particular to a portable electronic device with a writing teaching function and a method for teaching writing with the portable electronic device.

Background technique

With the advancement of electronic technology, various miniaturized portable electronic devices are constantly being introduced, such as personal digital assistants (PDAs), palmtop computers, mobile phones, etc., because of their small size and must be equipped with a display screen, they cannot A keyboard is set on it, or only some simple buttons (such as number keys and control keys) are set, so the convenience of its input is extremely poor. , so adopting handwriting input just becomes a kind of necessary solution.

In order to be able to input text by handwriting on the electronic device, as shown in FIG. 1, the personal digital assistant 11 must have a touch screen 12, and the user can write the desired input on the touch screen 12 with a stylus 13 or fingers. The text is to sense the written trajectory font by the touch screen 12. After the writing is completed, click a confirmation key 14 to complete the input of the handwritten strokes, and the written trajectory font will be handed over to the internal recognition module (not shown). , to identify the corresponding text and input it into the application program executed by the personal digital assistant 11 .

Although the above-mentioned handwriting input method can input characters to the portable electronic device more conveniently, however, the general recognition module only recognizes the written trajectory font, regardless of whether the written stroke sequence is correct or not. Therefore, it often causes the user to Wrong order of writing strokes without knowing it, and then causing bad writing habits, so it still needs to be improved.

Contents of the invention

The main purpose of the present invention is to provide a portable electronic device with a writing teaching function, which can automatically display the correct stroke sequence of the character after the user inputs a character into the electronic device by handwriting, and follow the correct stroke order Practice writing the text in sequence.

According to a feature of the present invention, the proposed portable electronic device with writing teaching function includes:

A touch screen for displaying data and inputting a character with handwriting strokes;

A handwriting recognition module, which is used to recognize the corresponding characters according to the handwriting strokes on the touch screen;

A character stroke sequence correspondence table, pre-stored with a plurality of characters and stroke sequence data corresponding to each character; and

A processing unit, used to display the handwritten characters on the touch screen in hollow fonts on the touch screen, and fill the hollow fonts sequentially according to the stroke sequence of the characters stored in the corresponding table. Each stroke of the text is restored to display the text in a hollow font for describing the text on the touch screen.

When writing the text on the touch screen, the processing unit monitors the strokes of the written text, so that the hollow font of the stroke will be filled only when it conforms to the sequence of the strokes of the text.

It also includes a stroke recording module, which records the stroke sequence of the characters input by handwriting strokes, and when the handwriting recognition module successfully recognizes the input characters, the processing unit will record the stroke sequence and the stroke sequence of the characters in the correspondence table Compared with the stroke order, when the two do not match, the text is displayed on the touch screen in a hollow font to teach the stroke order.

Detailed ways

For the portable electronic device with writing teaching function of the present invention and the method for teaching writing with the portable electronic device, please refer to the block of the portable electronic device with writing teaching function shown in Figure 2 Figure, which mainly includes: touch screen 21, processing unit 22, storage 23, character stroke sequence correspondence table 24, handwriting recognition module 25 and stroke recording module 26, etc., the aforementioned components are arranged in a personal digital assistant, for example , handheld computers, mobile phones and other portable electronic devices, the aforementioned handwriting recognition module 25 and the stroke recording module 26 can be individual hardware circuit elements or implemented with software or firmware and executed by the processing unit 22, the aforementioned The character stroke sequence correspondence table 24 can be a separate memory chip or recorded in the memory 23 , and the memory 23 also stores various programs executed by the processing unit 22 .

The aforementioned touch screen 21 can be used for electronic devices to display data, and the user can input a character with handwriting strokes; , by clicking a confirmation key (not shown) to complete the input of handwritten strokes; the handwriting recognition module 25 is coupled to the touch screen 21 to recognize the corresponding text according to the aforementioned handwritten strokes, and the processing The unit 22 displays the recognized text on the touch screen 21 or inputs it into the executed application program.

The aforementioned stroke recording module 26 is also coupled to the touch screen 21 , so that when the user handwrites a character on the touch screen 21 , it records the sequence of strokes actually written by the user. The aforesaid character stroke sequence correspondence table 24 pre-stores various characters and stroke sequence data corresponding to each character, which can be read by the processing unit 22 .

Fig. 3 shows a flow chart of the method for teaching writing with the aforementioned portable electronic device, and Fig. 4 is a corresponding schematic diagram, in which a dictionary software is executed on the electronic device to input a word to look up its meaning as an example. First, the user inputs a character on the touch screen 21 with handwritten strokes (step S301), such as the Chinese character "gold" shown in FIG. 4A. At this time, the stroke recording module 26 also records the actual written text stroke sequence, then, the handwriting recognition module 25 recognizes the aforementioned handwritten strokes (step S302), and when the corresponding characters are successfully recognized, the word meaning is searched according to the input characters and displayed to the user (step S303) , as shown in Figure 4B.

In step S304, the user selects the teaching of stroke order (steps S305-S308), or when the stroke order recorded in step S301 is not consistent with the stroke order stored in the character stroke order correspondence table 24, force Perform stroke sequence teaching (steps S305-S308). In step S305, the processing unit 22 displays the aforementioned input characters on the touch screen 21 in hollow fonts, as shown in FIG. 4C; Fill each stroke of the character of the hollow font (step S306), as shown in Figure 4D, restore the character to be displayed in a hollow font (step S307), for the user to describe the character on the touch screen 21 (step S308 ), as shown in FIG. 4E, at this time, the processing unit 22 monitors the strokes of the described characters, and only when the strokes of the described characters conform to the stroke order of the characters, the hollow font of the strokes will be filled, so, Effective stroke sequence teaching can be achieved.

As can be seen from the above description, the present invention automatically displays the correct stroke sequence of the input characters after the characters are input by handwriting, and allows the user to describe the characters according to the correct stroke sequence, so that the user can confirm whether the stroke sequence is correct or not. Correct their wrong stroke order, and effectively learn the correct writing habits.

The above-mentioned embodiments are only examples for convenience of description, and the scope of rights claimed by the present invention should be based on the scope of the patent application, rather than limited to the above-mentioned embodiments.
