Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a text input device and a method for inputting a character using syllable structure attributes,

The present invention relates to a method for improving the convenience and efficiency of a method of inputting characters in all computing devices including an input unit, an operation unit, and an output unit such as a computer, a smart phone, a tablet PC, a smart watch, and a hologram three-dimensional stereoscopic image.

Since the screen for inputting a mobile device is limited, it is difficult to implement a keyboard having many keys arranged to generate various input signals or to display a large number of icons on the same screen . In order to display a large number of keys or icons on the screen, it is necessary to reduce the size of each key or icon, which reduces the visibility and increases the possibility of erroneous operation in selecting a small-sized key or icon.

In the case of character input, for example, mobile devices are limited in their use of only one or two fingers. In order to input a large number of characters using a small number of keys, a method of assigning a plurality of characters to one key and identifying the assigned character is required.

One example is a method of assigning multiple characters to a key and then identifying a plurality of assigned characters according to the number of times the key is touched. The first character may be selected by touching the corresponding key only once, the second character may be input by successively inputting the key twice, and the nth character may be identified by touching the key n times.

Alternatively, a plurality of characters may be assigned to one key, and then, when the corresponding key is touched, the keys including the assigned characters are activated around the input key, and either one of the keys thus activated is selected, It is possible to think about how to find and input the desired character repeatedly.

Various input methods including the above method have been proposed, but most of the input methods so far have been to input desired characters and input them one by one. These methods need to repeat the operation of releasing the key input after one key input is completed, and then moving the finger position to the key to which the next character to be input is allocated. Therefore, the number of touches is increased and the fingering distance is increased.

Generally, in order for a computing device to input a character or perform a specific function of a program, a button must be selected for each input step to input a signal. This approach was impossible to transmit and process the next signal until one value was passed and processed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for easily and quickly inputting a desired signal chain through one continuous input operation by solving such inconvenience.

For convenience, the key is referred to as a " cursor key ". FIG. 15 is an embodiment of an extended keyboard activated when a cursor key assigned to the fourth position in FIG. 14 is selected. [16] is an embodiment in which a new extended keyboard assigned to a space key is activated according to a condition. FIG. 17 illustrates an example of the state of the clipboard activated when the 'paste ' key among the keys included in the extended keyboard of FIG. 16 is selected.

The present invention proposes a method of inputting characters efficiently and conveniently by reflecting the syllable structure characteristic of a language to be inputted to the keyboard.

For example, the Chinese character system consists of a large number of Chinese characters. Generally, since a keyboard used in a computing device is composed of dozens of keys, it is practically impossible or very inconvenient to directly assign Chinese characters to keys of a keyboard. Various input methods have been developed to overcome these inconveniences. The most widely used input method is to input Chinese characters by using Chinese Pinyin. Chinese Pinyin is a phonetic symbol used to denote Chinese Chinese characters in Roman numerals. (Hereinafter referred to as "Pinyin" by abbreviating Chinese Pinyin.) The input method using Pinyin is to input the pronunciation of Chinese characters using the alphabet, to search for the Chinese characters corresponding to the input pronunciation in the electronic dictionary, And inputting a desired Chinese character or a word in the input candidate words.

The pronunciation of every Chinese character forms a syllable. Here, syllable is a unit of pronunciation. In Chinese, syllable is made by combining moth and mica. The number of Chinese syllables is fewer than the number of Chinese characters but it reaches several thousand. It is not realistic to assign a pinyin chain corresponding to a syllable to each key on a keyboard composed of a limited number of keys. Therefore, in the method of inputting Chinese characters by using Pinyin, one Pinyin is assigned to one key as in the case of a QWERTY keyboard, or three or four Pinyin is assigned to one key as in a 3x4 keyboard, When selected, the method of inputting the pinyin is performed by a method of identifying the pinyin assigned to each key. For example, in a key of 'a', 'b', and 'c', each character can be identified by the number of times the key is selected successively. When this method is followed, it takes a lot of time to select the key many times in order to input one character.

On a typical computer keyboard, you can use 10 fingers to enter the pinyin, so the pinyin input itself is not a big deal. However, inputting a pinyin on a mobile device is a cumbersome and inconvenient task. When using a QWERTY keyboard on a mobile device such as a smart phone, the number of fingers that can be used for character input is limited to two. When entering a pinyin on a 3x4 keyboard in a smartphone, the number of fingers used for entering characters is limited to one.

The pronunciation of Chinese characters consists of as few as six to as many as one pinyin. Therefore, it is necessary to input more than 10 times to search for a word composed of two letters on a 3x4 keyboard. Therefore, it takes a lot of time and labor to select one key to input one Pinyin. The present invention proposes a method for improving the inconvenience through a method of inputting a pinyin by utilizing a Chinese syllable structure.

In general, the maximal structure of a syllable consists of a primitive, a neutral, and a longitudinal. Chinese also has elements corresponding to the beginning, the neutral, and the ending, but there are very few elements that correspond to the ending. For this reason, longitudinality is not described as a component of syllable, which is equivalent to a primitive or neutral. Therefore, the Chinese syllable is described as a binary structure consisting of the moth and mica. In this specification, Chinese is used in the meaning of Mandarin for convenience of explanation.

Chinese mothers correspond to the beginning of the general syllable structure, and mica corresponds to the loyalty and the longitudinal chain of the general syllable structure. There are more than twenty sounds that are used as Virgin Mary in Chinese. There are about 30 sound chains used as mica. Therefore, the number of Pinyin chains used in Chinese moth and mica is only a total of about 50.

The present invention improves input efficiency and convenience by assigning a plurality of Pinyin chains to each key on a 3x4 keyboard for use in input.

In addition, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. A computing device (not shown) for carrying out the present invention includes an input unit, an arithmetic unit, and an output unit. The input unit receives a signal from the user. The arithmetic unit computes a signal input from the user. The output unit outputs the operation result. The input unit and the output unit may be integrally provided. For example, the input section may be a touch sensor and the output section may be a display panel. Further, a touch screen panel including an input unit and an output unit may be provided. However, the present invention is not limited thereto. As described below, a mouse may be provided as an input unit.

In the present invention, a button or key refers to an element constituting a physical or virtual input device intended to generate a specific signal.

The keyboard includes an arbitrary number of keys, and includes a keyboard or a keypad. The keyboard includes an arbitrary number of keys, and each key is assigned a predetermined character or string. Each key displays a part or all of a predetermined character assigned to each key. The keyboard may also include any number of keys to which editing functions associated with text entry, such as pasting and moving a cursor, are assigned.

The computing device provides a keyboard for the user to enter characters. The keyboard includes a plurality of keys, and due to the limitation of the screen, each key is assigned a plurality of characters. The computing device senses the input to the keyboard and inputs the character selected by the user according to the detection result. Alternatively, the computing device may interpret the input to the keyboard as a specific command signal to change the keyboard or display a new keyboard. Alternatively, the computing device may interpret the input to the keyboard as a particular command signal, and perform commands corresponding to the key.

Selecting a specific key of the keyboard, activating the mothers and mothers assigned to the key or a string including them, selecting one of activated moths or mothers, repeating the process if necessary, And activating an extended keyboard including a number or a symbol to display a tone of the central vowel of the selected mica when the mica or syllable to be input is finally selected.

At this time, the character to be input can be selected by an operation of selecting the character activated by the first key input or by selecting one of the characters activated by the first key input, or by selecting a new character activated by the selection. Herein, the expression " operation for selecting any one of them " is an operation for dragging a finger used for the first key input into the activated characters, or an operation for activating one of the characters activated by the finger other than the finger used for the first key input The operation of touching one key on a qwerty keyboard used in a general computer, and the operation of inputting another key with another finger while holding a specific key. The other finger may be in the same hand or in the other hand.

The input does not have to be done only by touching with the finger. You can move the mouse cursor to a specific key on the virtual keyboard displayed on the computer monitor and then select the character to be input by clicking the left button of the mouse or by dragging with the other key while holding down the left button of the mouse. It is also possible to select a number or symbol to display the central vowel by moving the cursor over the keys of the active extended keyboard after the character to be input is selected. You can repeat the dragging of the cursor to select characters or strings to enter as needed.

1 shows the relative positions of the keys constituting the keyboard for convenience of explanation. [Figure 2] is an embodiment of a keyboard to which a Chinese language pinyin is assigned. 3 is an embodiment of an extended keyboard which is activated when a key at position 8 indicated by 'abc' is selected in [FIG. 2]. 3 is an embodiment in which 'a', 'b', 'c', and a character string including them are allocated to the extended keyboard. Each of the keys of the extended keyboard illustrated in FIG. 3 includes complex mica 'ai', 'ao', 'ai', and 'ai' including mothers 'b' and 'c' an ',' ang ', and' m 'are assigned to' bu ', which is the most frequently used syllable. When a mike 'ao' is selected among the keys of the extended keyboard illustrated in FIG. 3, a new extended keyboard composed of a plurality of keys to which a character string including mica 'ao' is assigned as illustrated in FIG. 4 Can be activated.

In one embodiment of the present invention, new syllables representing the central vowel of the syllable are displayed at the same time that a full Chinese syllable is selected through a series of key selection processes, or after the syllable is selected and a predetermined time elapses Extended keyboard can be activated and displayed. In the present specification, the central vowel is used to mean mica in which complex hairs are displayed in composite mica. 5 illustrates one embodiment of an extended keyboard that is activated when a key assigned with 'yao' in FIG. 4 is selected. The extended keyboard is one of embodiments in which numeric keys are assigned to indicate a tone for convenience of explanation. The input device can be configured such that 'yao3' is input by selecting any one of the keys of the extended keyboard illustrated in FIG. 5 (for example, '3'). The string 'yao3' input through the above method reflects the character string indicated by the numeral '3' in 'a', which is the central vowel of 'yao'

. ≪ / RTI > This makes it possible to search Chinese word input candidates faster and more accurately than when searching with syllable-free syllables or syllable sequences.

In the present invention, it is not necessary that the extended keyboard including the numbers or symbols representing the above-mentioned expressions is activated only when a key assigned with a complete syllable is selected. For example, in FIG. 3, keys 6 and 12 are assigned mica 'an' and 'ang', respectively. Generally, these mica are selected after the Virgin is selected or Virgin is selected. Accordingly, when selecting a key assigned 'ang' in the extended keyboard illustrated in FIG. 3, it is possible to configure the extended keyboard to display an extended keyboard of 'ang' as illustrated in FIG. 6 have. Then, one of the keys of the extended keyboard may be selected to determine the tones of the mica.

The method of inputting the pinyin by activating the extended keyboard can also be applied to the keys assigned to the Virgin. 7 is an embodiment of an extended keyboard which is activated when the ninth key assigned with the consent "ch" in FIG. 3 is selected. As illustrated in FIG. 7, some of the Chinese syllables that start with the word 'ch' may be assigned to each key of the extended keyboard. At this time, when the specific key of the extended keyboard is selected, the character assigned to the corresponding key is inputted. When the key is deselected without selecting any key of the extended keyboard, the character or string And 'ch' in the case of FIG. 7).

In the present invention, the input of a string does not necessarily have to be the extended character of the basic character assigned to the key of the keyboard. Also, the string assigned to the keyboard need not necessarily consist of Chinese characters. The string assigned to each key may be a symbol that symbolizes a particular Chinese Pinyin chain. For example, there are six syllables with mica 'uang', among which the six pinyin chains constitute one syllable. When assigning them to the key of the 23rd position, six syllables can be allocated to each key of the extended keyboard which is activated when the 23rd key is selected, as illustrated in FIG. At this time, it is difficult not only to display all of the pincushion chains assigned to each of these in a narrow key space, but it is not necessarily required. Therefore, some of these syllables may be displayed using a symbol representing them as illustrated in [FIG. 9].

One of the inconveniences when entering Chinese words is when searching for a word consisting of a single letter. Since the Chinese Pinyin chain, which does not display the Chinese characters, includes all the Chinese characters, there are some hundreds or even dozens of the same Chinese words. Therefore, in order to effectively search for the desired Chinese character in this case, it is necessary to display the tone of the word to be searched. However, as exemplified in FIG. 3, the characters (columns) that can be input by the extended keyboard which is activated when the key of the 8th position is selected are the extended characters including the mica 'a' c 'are extended characters. At this time, for a character string excluding mica 'a', a procedure may be provided for activating an extended keyboard including a number or a symbol representing a tone, while a method for displaying the tone of mica 'a' itself has not been disclosed . Therefore, in order to effectively search for a Chinese word having mica 'a', a method of displaying the mosaic of 'm' should be provided.

For example, as shown in FIG. 11, when a key of the 14th position assigned '4' is selected from the newly activated extended keyboard and the selection is released, a string of mica 'a''a4' may be input. The input 'a4' is a mica (4

The input method relates to a method for inputting a Pinyin to search for a Hanja word to be input. The input of the Chinese character word is completed by searching for a Chinese character word corresponding to the input Pinyin chain and then selecting a desired Chinese character word among the Chinese character words. To this end, a Chinese input device implemented in a mobile device such as a smart phone includes an input candidate window similar to that illustrated in FIG. 12. Generally, input candidate words are arranged from left to right according to their priority in the input candidate window. When entering characters using the right hand, the word with the highest priority is located at the left end of the input candidate window. To solve this inconvenience, the space key used to insert a blank character is used as a method for selecting the first input candidate. That is, when the space key is selected and released, the signal generated at this time is replaced with a signal generated when the first input candidate is selected, so that the first input candidate is inputted. This method is effective as a method of selecting the first input candidate, but it is still inconvenient to select the input candidate word when the second or third or fourth word is the input candidate.

According to an aspect of the present invention, an input method can be configured such that when the space key is selected, the extended keyboard is activated and a number indicating the position of the second or less input candidate words of the input candidate window is displayed in each of the keys on the activated keyboard have. When a key having a specific number is selected, a signal generated at this time is replaced with a signal generated when a word at the position indicated by the number is selected, and an input method for inputting the input candidate at the corresponding position can be configured.

As for the method of inputting a character, there is a method of searching for a word and inputting it as described above, and there is a method of copying and inputting a part of the created document. One way to select a portion of a copy from a mobile device, such as a smartphone, is to place a finger on the portion of the document that you want to copy, make the area of the copy appear, and then adjust the first and last I confirm it. When the part to be copied is confirmed, the copy or cut menu is displayed.

When this method is followed, in the case of copying more than the portion displayed on the screen, there is inconvenience that the region selection is canceled in the process of making the mark of the end of the region.

According to an aspect of the present invention, a predetermined extended keyboard to which a function related to movement of a cursor is assigned, as illustrated in FIG. 14, may be assigned to a specific function key. When the function key is selected, the extended keyboard assigned with the function of moving the cursor forward or backward in units of letters or words may be activated, as illustrated in FIG. It may also contain a key that moves the cursor to the beginning or end of the document. When the user selects any one of the keys in a state in which the extended keyboard is activated, the input method may be configured such that the cursor moves according to the function assigned to the key.

According to one aspect of the present invention, as shown in FIG. 16, when a user selects a function key while positioning a cursor at a beginning of a document to be copied according to a method of moving the cursor, An extended keyboard including keys having icons corresponding to the point and the end point is activated and a start position to be copied can be specified by selecting an icon indicating the start point. Then, when the cursor is positioned at the end point of the portion to be copied and the key having the icon indicating the end point is selected on the extended keyboard, the contents of the document between the start point and the end point can be designated. When the function key is selected in a state in which a region to be copied is selected, the keys indicating how to operate a document in a designated area such as 'copy', 'cut', 'paste'

Generally, when you paste a copy from a mobile device with a touch screen into another document, touch the location where you want to paste it with your finger. After a certain period of time, the window containing the 'Copy' or 'Clipboard' Copy 'menu, the contents stored in the clipboard are copied to the specified position in the document. At this time, the window containing the menu is usually activated adjacent to the cursor, and in some cases it is necessary to extend the finger far enough to manipulate it.

According to one aspect of the present invention, an extended keyboard to which a function of 'copying', 'cutting', 'pasting', or the like is allocated is assigned to a specific function key, and when the corresponding key is selected, The input method can be configured so that the corresponding function is performed by selecting the key marked with the function. At this time, when the key assigned with the 'paste' function is selected on the extended keyboard, the content copied immediately before is input to the designated position, and at the same time, the key having the 'paste' The clipboard may be activated in a separate window as illustrated in FIG. The clipboard can be configured to scroll up and down.
