Description

Electronic device equipped with touch type Chinese character input system

The invention relates to a Chinese character input method, in particular to a Chinese character input method suitable for a 3×3 keyboard.

English or French is a phonetic transcription, and readers can understand the pronunciation of the words directly from the text itself. However, Chinese characters are not a kind of phonetic characters. Readers cannot directly understand the pronunciation of the characters themselves, but must remember the way they are pronounced. In Taiwan, in order to let learners understand the pronunciation of different Chinese characters, 37 phonetic symbols are used to annotate the pronunciation of Chinese characters. Each phonetic symbol represents a different phonetic unit. In mainland China, the Latin alphabet is used to annotate different Pinyin units. This is the Chinese Pinyin.

The pronunciation of Chinese characters is roughly composed of 21 initials and 36 finals. The finals can be divided into: sound, non-combined rhyme, and combined rhyme. The so-called combination rhyme combines the combination of polyphonic and non-combined rhyme. A pinyin unit. Taking the phonetic symbols as an example, the detailed classification is shown in the following list 1. It can be seen from Table 1 that the number of initials is twenty-one, the number of sounds is three, and the number of non-combined vowels is thirteen, plus twenty-one combined rhymes. In addition to the cockroaches that are not used directly, there are a total of 36 finals.

On electronic devices (such as computers, mobile phones, and remote controls), when the user inputs the Chinese characters using the phonetic input method, the initials and finals must be input, or the initials, mediates, and finals must be input. For example, when you enter the word "package", you first enter the initial "ㄅ" and then the final "ㄠ". When inputting the word "中", the initials "ㄓ" are input first, then the mediatic "ㄨ" is input, and then the finals "ㄥ" are input. In order to speed up the input speed of Chinese characters, some people also arrange different combinations of rhymes on different keys, so that the user does not need to input another medium tone when inputting, but directly inputs the combination rhyme, thereby increasing the input speed. .

However, no matter which input method is used, when it is applied to a handheld device such as a mobile phone, some problems described below may occur:

(1) Since the size of a handheld device such as a mobile phone has its limitation, if a standard keyboard is to be placed thereon, the area allocated to each button is often small, which is prone to false touch; or

(2) If only a 3×3 keyboard is configured on a handheld device such as a mobile phone, several Pinyin units must be placed on one button. This is called a Multi-tap keyboard, and then the user selects the appropriate Pinyin unit. But this will make the input slower.

(3) At present, many handheld devices (such as iphone and ipad) are equipped with touch screens, so users can input them by hand. However, at present, the accuracy of the handwriting recognition software in the recognition of Chinese characters is still insufficient, which will make the input speed slower.

Therefore, how to design a Chinese character input system, which is applied to a 3×3 keyboard and allows the user to maintain a certain input speed, is worthy of consideration by those who have ordinary knowledge in the field.

The main object of the present invention is to provide a Chinese character input system which is suitable for use on a 3 x 3 keyboard and which allows the user to maintain a certain input speed.

According to the above and other objects, the present invention provides an electronic device having a Chinese character input system installed therein. The electronic device includes a 3×3 keyboard having a central grid, four corners, and Four side panels, the central grid is located at the center of the 3 x 3 keyboard, and the four corner grids are located at the corners of the 3 x 3 keyboard. The Chinese character input system maps different input orders to different initials or finals. The Chinese character input system classifies different input sequences into the following groups: (a1)~(f1). In (a1), the order of input is: one of the corners, the central grid, or: one of the squares, the central grid. In (b1), the order of input is: one of the corners, the sidebar adjacent to the corner, and the central grid. In (c1), the order of input is: one side, the corner adjacent to the side, the other side adjacent to the corner, and the center. In (d1), the order of input is: one of the corners, the sidebar adjacent to the corner, and the central grid. In (e1), the order of input is: a central grid, one of the squares, and a corner lattice adjacent to the square. In (f1), the order of input is: a central lattice, a side lattice, a corner lattice adjacent to the square lattice, and a margin lattice adjacent to the corner lattice. When the input order is one of (a1)~(c1), the Chinese character input system corresponds to one of the initial or final of the Chinese character. When the input order is one of (d1)~(f1), the Chinese character input system corresponds to: the other of the initial or final of the Chinese character.

In the above electronic device, when the input order is one of (a1) to (c1), the Chinese character input system corresponds to: the initial of the Chinese character. When the input order is one of (d1)~(f1), the Chinese character input system corresponds to the final of the Chinese character.

According to the above and other objects, the present invention further provides an electronic device having a Chinese character input system, the electronic device comprising a 3×3 keyboard having a central grid and four corners. With four side grids, the central grid is located at the center of the 3×3 keyboard, and the four corners are located at the corners of the 3×3 keyboard. The Chinese character input system divides the order of input into the following groups: (a1)~(f1). In (a1), the order of input is: one of the corners, the central grid, or: one of the squares, the central grid. In (b1), the order of input is: one of the corners, and the sidebar adjacent to the corner. In (c1), the order of input is: one of the squares, and the corner lattice adjacent to the side square. In (d1), the order of input is: central grid, one of the corner grids, or: central grid, one of the grids. In (e1), the order of input is: one of the squares, and the corner lattice adjacent to the side lattice. In (f1), the order of input is: one of the corners, and the sidebar adjacent to the corner. When the input order is one of (a1)~(c1), the Chinese character input system corresponds to one of the initial or final of the Chinese character. When the input order is one of (d1)~(f1), the Chinese character input system corresponds to: the other of the initial or final of the Chinese character.

In the above electronic device, when the input order is one of (a1) to (c1), the Chinese character input system corresponds to: the initial of the Chinese character: when the input order is (d1)~(f1) In one of them, the Chinese character input system corresponds to: the final of the Chinese character.

The above described objects, features, and advantages of the present invention will become more apparent from the following description.

Please refer to FIG. 1. FIG. 1 illustrates a smart phone equipped with a touch screen, which is a first embodiment of the electronic device of the present invention. The smart phone 100 has a touch screen 101, and the smart phone 100 is internally provided with a Chinese character input system. The Chinese character input system is stored in the smart phone 100 in a software manner. When the user wants to input Chinese characters, a 3×3 keyboard 110 is displayed on the touch screen 101. Next, please refer to FIG. 2, which is illustrated as a 3×3 keyboard. The 3×3 keyboard 110 has a central grid 112, four corners 114, and four sidebars 116. The central grid 112 is located at the center of the 3x3 keyboard 110, namely: button 5. The four corners 114 are respectively located at the corners of the 3×3 keyboard 110, namely: button 1, button 3, button 7, and button 9. Each side cell 116 is adjacent to the central cell 112 and its two diagonal cells 114, namely: button 2, button 4, button 6, and button 8.

Among them, the Chinese character input system uses different input sequences to correspond to different initials or finals to input Chinese characters. Please refer to FIG. 3A to FIG. 3F. FIG. 3A to FIG. 3F illustrate embodiments of various input sequences. In Figures 3A-3F, the arrows represent the order of the inputs. In the input of the initials, the Chinese character input system of this embodiment classifies the different input sequences into the following three categories:

(a1) The input order is: first touch one of the corners 114 and then touch the center grid 112. Alternatively, the order of input may be: first touch one of the cells 116, and then touch the central cell 112. There are eight different input methods in the input order of this class. For example, the initial "ㄐ" can be assigned to the input sequence described below: first touch the button 1, then touch the button 5 (as shown in Fig. 3A). Alternatively, the initial "ㄔ" may be assigned to the input sequence described below: first touch the button 2, and then touch the button 5 (as shown in Fig. 3A).

(b1) The input order is: first touch one of the corners 114, then touch the sidebar 116 adjacent to the corner 114, and then touch the central compartment 112. There are eight different input methods in the input order of this class. For example, the initial “ㄆ” can be assigned to the following input sequence: first touch the button 1, then touch the button 2 (the button 2 is adjacent to the button 1), and then touch the button 5 (as shown in Figure 3B). .

(c1) The input order is: first touch one of the cells 116, then touch the corner 114 adjacent to the sidebar 116, then touch the other side 116 adjacent to the corner 114, and finally touch the central grid 112. There are eight different input methods in the input order of this class. For example, when the user touches the button 4 first, then touches the button 7 (the button 7 is adjacent to the button 4), then touches the button 8, and finally touches the button 5, the input sequence corresponds to the initial “ㄗ” "(Figure 3C).

It can be seen from Table 1 that there are 21 initials for Chinese characters, but there are a total of 24 input methods covered by the three input sequences (a1) to (c1). Therefore, the input of the initials can be performed using the 3 x 3 keyboard 110 by the difference in the input order. In addition, as can be seen from FIG. 1, the 3×3 keyboard 110 is a virtual keyboard displayed on the touch screen 101, so that the user's finger can slide on the 3×3 keyboard 110, and (a1)~(c1) The input sequence can be completed with continuous strokes, which speeds up the input.

Moreover, after comparing (a1), (b1), and (c1), it can be found that since (a1) only needs to touch two buttons to complete the input, there is a faster input speed, but (c1) You need to touch 4 buttons to complete the input, so the input speed is relatively slow. Therefore, the designer of the Chinese character input system can divide all the initials into the following three groups according to the frequency of use: the first common consonant group, the second common consonant group, and the third common consonant group. Among them, the initials in the first common consonant group, for example: ㄐ, ㄑ, ㄒ, can be classified into the input order with the fastest input speed (a1). The initials in the second common consonant group, for example: ㄅ, ㄆ, ㄈ, are classified into the (b1) input order with the second fastest input speed. The initials in the third common consonant group, for example: ㄖ, ㄙ, ㄇ, are classified into the (c1) input order with a slower input speed. This will increase the overall input speed.

In the input of the final, the Chinese character input system of this embodiment classifies the different input sequences into the following three categories:

(d1) The input order is: first touch the central grid 112, then touch one of the corners 114. Alternatively, the order of input may be: first touch the central grid 112, and then touch one of the compartments 116. There are eight different input methods in the input order of this class. For example, when the user first touches the button 5 and then touches the button 9, the input sequence corresponds to the final "ㄢ" (as shown in FIG. 3D). Alternatively, when the user first touches the button 5 and then touches the button 8, the input sequence corresponds to the mediatic "ㄨ" (as shown in FIG. 3D).

(e1) The input order is: first touch the central grid 112, then touch one of the compartments 116, and then touch the corner compartment 114 adjacent to the sidebar 116. There are eight different input methods in the input order of this class. For example, when the user touches the button 5 first, then touches the button 2, and then touches the button 3 (the button 3 is adjacent to the button 2), the input sequence corresponds to the final "ㄠ" (as shown in Fig. 3E). Show).

(f1) The input order is: first touch the central grid 112, then touch one of the compartments 116, then the diagonal compartment 114 adjacent to the diagonal compartment 116, and finally touch the other compartment 116 adjacent to the diagonal compartment 114. There are eight different input methods in the input order of this class. For example, when the user touches the button 5 first, then touches the button 6, then touches the button 9 (the button 9 is adjacent to the button 6), and finally touches the button 8 (the button 8 is adjacent to the button 9), then The input order is corresponding to the initial “ㄡ” (as shown in Figure 3F).

It can be seen from Table 1 that there are 3 Chinese tones and 13 Chinese vowels, but there are a total of 24 input methods covered by the three input sequences (d1)~(f1). Therefore, by inputting the difference in the input order, the 3×3 keyboard 110 can be used to input the tone and final. In addition, the designer of the Chinese character input system can also follow the practice of the initials, and divide all the vowels according to the frequency of use into the following three groups: the first common vowel group, the second common vowel group, and the third common vowel group. Among them, the finals in the first commonly used final family can be classified into the fastest input order (a1). The finals in the second common vowel group can be classified into the (b1) input order with the second fastest input speed. The finals in the third commonly used final family can be classified into the (c1) input order with slower input speed. This will increase the overall input speed.

In the three input sequences (a1)~(c1), the last touch button is button 5, and in the three input sequences (d1)~(f1), the first touch button is For button 5. Therefore, when the user inputs a Chinese character, the input can be completed in a continuous manner, thereby increasing convenience. For example, when the user inputs the word "run" in Chinese characters, the input order can be: button 1, button 2, button 5, button 2, button 3, since these buttons are connected to each other, The way you can complete the input.

As can be seen from Table 2, there are a total of 36 mediators, finals, and rhymes, but the input order covered by (d1)~(f1) is only 24, so some pinyin units cannot be covered. . However, in the vowels of Chinese characters and the combination of rhymes (hereinafter collectively referred to as vowels), some are mutually exclusive. The so-called vowels that are mutually exclusive refer to vowels that are not connected to the initials at the same time, so that the vowels that are mutually exclusive can be assigned to the same input order. For example, “ㄩㄝ” and “ㄨㄟ” are the vowels that are mutually exclusive. In the pronunciation of Chinese characters, there is the pronunciation of “ㄓㄨㄟ”, but there is no pronunciation of “ㄓㄩㄝ”, "This pronunciation, but there is no pronunciation of "ㄒㄨㄟ". In this way, when the Chinese character input by the user includes the initials and the finals, the Chinese character input system can determine which finals to correspond to by the initials input by the user. According to the information inquired by the inventor of the present case, there are 12 sets of repetitive finals, and the input order covered by (d1)~(f1) can cover all the finals. To simply enter the finals, the menu can be listed on the screen for the user to select. Alternatively, it can be combined with other key input methods to distinguish, for example, the original input order of “ㄨㄟ” and “ㄩㄝ” will be the same, but when inputting “ㄨㄟ”, it can be input with other keys, so that It is possible to distinguish from the input of "ㄩㄝ".

In the above Chinese character input system, the input order of (a1), (b1), (c1) corresponds to the initial, and the input order of (d1), (e1), (f1) corresponds to the final, such The design is convenient for the user to input a stroke. However, those skilled in the art can also associate the input order of (a1), (b1), and (c1) with the finals according to the situation, and the input orders of (d1), (e1), and (f1). To the initials.

In addition, the Chinese character input system of the present invention can be applied not only to the virtual keyboard on the touch screen 101, but also to other electronic devices that do not have a touch screen. For example, a general stick or joystick can be connected to a general desktop computer or a video game. When the Chinese character input system is activated, it will be displayed on the desktop computer. A 3 x 3 keyboard. When inputting Chinese characters, when the user swings the joystick, the 3×3 keyboard on the screen will display the swing direction of the joystick, and the swing directions will correspond to the input order of the 3×3 keyboard. For example, when the user swings the joystick to the upper right, the 3x3 keyboard displays the input sequence from button 5 to button 8. When the user is accustomed to the input mode, the 3×3 keyboard may not be displayed on the screen, that is, the 3×3 keyboard is only stored in the Chinese character input system. In addition, since the preset position of the rocker is located at the center, that is, corresponding to the position of the button 5, when the initial is input, the joystick must be pushed to the predetermined position before input. For example, when the initial “ㄆ” is input, the joystick is first pushed to the position corresponding to the button 1, and then the input of the initial “ㄆ” is performed.

Alternatively, the Chinese character input system can also be applied to a conventional physical keyboard. Since it is difficult to input by sliding on a physical keyboard, in order to increase the speed of user input, those skilled in the art can modify the input order of (b1), (c1), (e1), (f1). The modified implementation is as follows:

(b1') The input order is: first touch one of the corners 114, and then touch the sidebar 116 adjacent to the corner 114.

(c1') The input order is: first touch one of the cells 116, and then touch the corner 114 adjacent to the sidebar 1116.

(e1') The input order is: first touch one of the cells 116, and then touch the corner cell 114 adjacent to the sidebar 116.

(f1') The input order is: first touch one of the corners 114, and then touch the sidebar 116 adjacent to the corner 114.

Although the input order of (b1') and (f1') is the same, and the input order of (c1') and (e1') is the same, since (b1') and (c1') correspond to the initial, (c1 ') and (e1') correspond to the finals, so there is no conflicting problem. If you only want to simply enter the initial or final, you can list the menu on the screen for the user to select. Alternatively, it can be combined with other key input methods to distinguish.

In the above embodiments, although the phonetic symbols are used to represent various initials and finals, those skilled in the art should clearly understand that Chinese Pinyin, General Pinyin or other Pinyin can be used to indicate initials and finals. Therefore, regardless of whether the user knows the phonetic symbol, as long as he understands the pronunciation of the Chinese character, the Chinese character input system of the embodiment can be used to input the Chinese character. In addition, the electronic device described above is a mobile phone as an embodiment, but those skilled in the art can also use it on other electronic devices, such as a tablet computer (eg, an iPad).

The present invention has been described above by way of examples, and is not intended to limit the scope of the claims. The scope of patent protection is subject to the scope of the patent application and its equivalent fields.
