BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information inputting system,

The present invention relates to an information input system using an extended key and an information input method using the information input system, and more particularly, to an information input system and an information input method through word prediction.

Specifically, the input system of the compact digital device is provided with an extended key. When the extended key is selected, a new item is allocated to the extended area, so that the user can input newly allocated information. At this time, The present invention is directed to an invention characterized in that it can be made to be as follows.

Recently, many small digital devices such as mobile phones and game machines have been introduced and used.

These compact digital devices are loved by many people because they can be carried and used anytime and anywhere. For this reason, various products are expected to be miniaturized in the future.

On the other hand, a problem in such a small digital device is that there is not enough space available for inputting various kinds of information such as characters.

For example, in a mobile phone, all letters, numbers, and the like must be input using only a total of 12 keys. In order to input information using only a small number of keys, a qwerty keyboard The input speed is inconvenient and the input speed is inevitably slowed.

In the case of Hangul, the input method has been diversified as mobile phones become more common than any other characters. The reason for this is in the diversity of the method of separating consonants and vowels and in the variety of ways of expressing each letter.

That is, the reason why the various methods exist is to reduce the number of key presses as much as possible, and to reduce the distance that the finger moves in order to press the key, so that the user can conveniently input characters .

In spite of this research, it is still uncomfortable compared to the QWERTY keyboard, and developers of each product can reduce the number of key presses as much as possible while minimizing the number of keys, There are many studies to develop a method to reduce moving distance.

In addition to Hangul, research on input devices of other languages such as English, Chinese, and Hindi has been actively pursued to find a more efficient input method as in Hangul, but there is still no revolutionary method developed. Recently, It is a fact that keyboard is adopted.

Until now, the well-known Hangul character input system has been difficult to bring about the intuitiveness of the user because it is arranged regardless of the shape of the vowel in order to reduce the movement of the possible fingers. On the other hand, in order to minimize key movement, the present invention assigns a consonant among Korean alphabets as a primary character of all keys, and inputs the consonants when they are pressed for the first time, By specifying at least one key for input and specifying it as a vowel input activation key, the number of keys for Hangul characters can be minimized. In other words, after pressing the vowel input activation key, the vowel can be input even if the key is already designated as a consonant, so that both consonants and vowels can be inputted by one key. As a result, the number of independent keys for the vowels is reduced, the number of the entire keys is reduced, and as a result, the movement distance of the finger for the input of Korean characters is minimized, thereby further enhancing the convenience of the user. This principle can be applied to Hindi and Chinese. In the case of 'Disambiguity Text Input Method', a 'predictive word selection function key (extended key)' corresponding to the 'vowel input activation key' of Korean is set It is possible to minimize the number of keys required for character input by performing various additional functions in addition to selection of a predicted word, and further facilitate the selection process of the predicted word, thereby increasing the convenience and efficiency of the user.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 is a block diagram showing a configuration of the present invention.

The information input system of the present invention includes an input unit 110, an input analysis unit 120, and an output unit 130.

First, the input unit 110 has a plurality of divided regions, i.e., a plurality of divided regions, and detects whether each of the divided regions is selected by the user.

This division region may be formed at intervals from the other division regions, or may be formed in connection with other division regions in the entire region formed by one.

Whether or not each divided area is selected can be detected by detecting that each divided area is pressed, a finger of a user is touched, or is separated after being touched.

In addition, it is not a matter of detecting whether each divided area is selected by any one method

For example, in the case of a keypad type used conventionally in mobile phones or the like, each key constituting the keypad is constructed by being separated from other keys.

Meanwhile, in the case of using an input system such as a touch pad or a touch screen, a touch pad or the like is divided into a plurality of divided regions, and a method of detecting a divided region in which a user touches a position is used You can get the same effect as the keypad.

In addition, even if the input unit 110 is configured using a touch sensing means such as a touch pad or a touch screen, it may be determined whether or not the user has selected the divided region using whether or not the user has pressed the input unit 110 .

For example, using the contact area of the user's finger, it is possible to judge whether the user simply touches or presses.

In the case of an apparatus for judging whether or not contact is made by using a change in the amount of charge, the amount of charge is proportional to the contact area. Therefore, when the amount of charge generated is changed by more than a predetermined threshold value, It is possible to judge whether the user touches the input unit 110 only by pressing or touching by using only the means for detecting the contact.

Alternatively, a pressure sensor may be provided under the means for detecting touch such as a touch pad, so that when the user depresses the touch pad or the like, the touch pad is depressed so that the pressure sensor positioned below can detect the touch.

FIG. 2 is a structural view of the case where the pressure sensor 202 is provided under the contact sensing means 201.

As shown in FIG. 2, the touch sensing sensor 201 such as a touch pad can be moved up and down when the user presses the touch sensor. When the user presses the pressure sensor 202 over a predetermined pressure, So that it is possible to detect whether or not the user presses the button.

The method of moving the contact detecting means 201 may be such that the entire touch detecting sensor 201 is pressed horizontally or may be inclinedly pressed as shown in FIG. There is no limit to the method.

Alternatively, the touchpad may be arranged in the same manner as a keypad. That is, the surface of each key constituting the keypad is configured as means for detecting contact, thereby determining whether the user has touched the key. If the key is depressed, the same method as detecting the depression on the conventional keypad It is possible to judge whether or not the user touches and presses at the same time.

The input unit 110 receives information on whether the user selects the division area selected by the user based on whether the user touches the input unit 110 or the input unit 110 is pressed, (120).

Whether or not the user has selected a particular partition may be determined based on only one criterion, such as whether the user has touched the partition, pressed it, or separated it after the contact, It is possible.

This will be described in more detail in the following embodiments.

The input analysis unit 120 interprets and determines the information that the user desires to input using the information that each of the divided regions of the input unit 110 has contacted, pressed, or separated.

That is, the input analyzing unit 120 assigns a specific item to each of the divided areas of the input unit 110, and when a specific divided area is selected, it is interpreted that the information allocated to the divided area is inputted.

At this time, an extended key for selecting one of the plurality of pieces of information is assigned to at least one of the plurality of divided areas of the input unit 110, and when the extended key is allocated, The item assigned to the extended key is newly assigned.

In this case, it is preferable that the divided area to which the extended key is allocated is excluded in the extended area, and only the divided area adjacent to the divided area to which the extended key is allocated is used as the extended area.

In this state, when the user again selects the divided area to which the newly allocated item is allocated, the input analysis unit 120 interprets that the information corresponding to the item is inputted.

If the number of information allocated to the extended key is greater than the number of divided areas included in the extended area by the extended key, when the extended key is first selected, only a part of the information is allocated to the predetermined divided area, It is interpreted that the remaining information is re-allocated to the predetermined divided area, and interpreted as information inputted to the divided area according to the selected divided area.

On the other hand, when the extended key is set and new information is assigned to the divided area determined according to the extended key, the input analyzing unit 120 selects the divided area to which the new information is allocated, and determines that one piece of information is inputted , And allocates the initially allocated information to the divided area to which the new information is allocated. That is, initialization.

In addition, even if the number of divided areas included in the extended area according to the extended key is equal to the number of information to be newly allocated to the divided area, even if the extended key is selected only once, the divided area included in the extended area is given If all of the information to be allocated is available, the user may return to the initial state by selecting the extended key again.

The information allocated to the area determined by the extended key may be always constant or may be variably determined according to the extended key. This will be examined again through a concrete example.

The extended key may be assigned to only one of the plurality of divided areas, or may be assigned to a plurality of divided areas.

Also, each time an extension key is selected, an extension area, which is a divided area to which new information is allocated, may be set differently for each extension key.

On the other hand, the output unit 130 informs the user of information allocated to each divided area, such as an LCD screen, to the user, which information is currently allocated to each divided area.

The output unit 130 may be particularly useful when the input unit 110 is implemented in the form of a touch screen.

When the input unit 110 is implemented as a touch screen, the output unit 130 outputs a divided area on the screen corresponding to the position and size of each divided area of the input unit 110, Display information.

When the input unit 110 is implemented in the form of a touch pad or a keypad, it is possible to indicate what information is allocated to each divided area of each key or touch pad, so that the output unit 130 is not necessarily required .

In this case, even when the information allocated to each of the divided areas is output to the screen, the entire divided area may be displayed, or only information indicating what information is currently allocated to the divided area selected by the user may be displayed And an indication that a particular extension key has been selected may be output only when the extension key is selected.

3 is a flow chart illustrating one embodiment of the method of the present invention.

First, when a user selects a specific divided region in the input unit 110 having a plurality of divided regions (301), the input analysis unit 120 determines whether the divided region is a divided region to which the extended key is allocated ( 302).

If the selected partition is not the partitioned area to which the extended key is allocated, the input analysis unit 120 interprets that the item allocated to the selected partitioned area is input (307).

If the selected partition is a partitioned area to which the extended key is allocated, the input analysis unit 120 allocates new items to the extended area defined in the extended key (303), and if the partitioned area belonging to the extended area is selected (304), it is interpreted that the item newly allocated to the divided area belonging to the extended area is input (305).

Otherwise, if the partitioned area to which the extended key is allocated is selected again (308), new items are set in the extended area again (303) so that the user can select again from the new options.

If a divided area to which an extended key is allocated is selected again or a divided area belonging to the extended area is not selected, that is, a divided area other than the extended area is selected, The reallocation operation by the extended key is invalidated and the information allocated to the last selected partition is input by the user (305).

When one input is completed, it is determined whether there is an additional input (306), and the above process is repeated.

The input system and input method of the present invention can be used in various fields.

It can be used for a character input system in a mobile device such as a mobile phone, PDA or the like.

Hereinafter, specific embodiments will be described with reference to the drawings.

[Example 1]

Fig. 4 shows an example in which the input system of the present invention is used in a game machine.

The contents shown in (I) and (II) of FIG. 4 are implemented in the form of a touch pad 400 as an input system used in a game machine, and each rectangle divided by a dotted line represents a divided area.

It is also assumed that the divided areas 401, 402, 403, and 404 are divided areas to which the extended keys are allocated.

When the user wants to select or execute a specific menu while playing a game on the touch pad in a manner such as dragging, the user selects one of the divided areas 401, 402, 403, and 404 Quot; region "

At this time, the selection of the divided area may be made by simply touching or touching, or may be made when the finger is separated from the position where the divided areas 401, 402, 403, and 404 are present in the touched state, , 402, 403, and 404, and may be formed when the finger is pushed.

In order to recognize that the selection is made when the finger is pressed, a threshold value may be set in advance so as to distinguish the touch from the touch according to the contact area as described above. Alternatively, the pressure sensor may be provided at the lower end of the touch pad have.

If the user selects the divided area 401, the divided areas 405 and 406 to which no information is assigned before that become the extended area, and menu 1 and menu 2 are assigned to the extended area.

When the user selects the divided area 405 or the divided area 406 in this state, the corresponding menu is selected and executed.

The method of selecting the menu 1 or the menu 2 can also be performed by the system designer by any one of touching, pressing, and spacing.

When the user selects the menu 2, the user presses the divided area 401 to which the extended key is allocated, and then moves (drag) to the divided area 406 to which the menu 2 is allocated as it is in contact with the hand, It may be the most convenient way to recognize menu 2 as being selected if it is spaced apart.

In the following embodiments, the present invention will be described with reference to embodiments that can be applied to a Hangul input system.

[Example 2]

5 shows an example in which the present invention is applied to an input system of a general mobile phone. FIG. 5 shows a case where an extension key is allocated only to the fifth key 501, and FIG. Lt; RTI ID = 0.0 > a < / RTI >

As shown in FIG. 5, there is no vowel assigned to each division area (key) at first, and the vowel is allocated only when the extension key is selected.

That is, the extended key is used as the vowel input activation key. When this extended key is selected in the character input mode, the divided area to which 1, 2, 3, 4, 6, 7, 8, and 9 keys are allocated is used as an extended area of the extended key, do.

In this manner, when the vowel input activation key, which is an extended key, is selected, the extended area to which the characters are reallocated is preferably a divided area adjacent to the vowel input activation key and surrounded by a square. In this case, it is possible to input the vowel while minimizing the movement of the finger after pressing the activation key of the vowel input.

In the case of FIG. 5, the arrangement of the consonants is easily inputted by designating 'ㅁ', 'ㅇ', and 'ㅅ', which are commonly used, to one key, and each key is pressed up to three times to input all consonants . In case of 'ㄲ', it is input by pressing key 1, 3 times. In case of 'ㅂ' and 'ィ', key 4 is inputted by pressing 2 and 3 times respectively.

5 does not specify a vowel. In order to input a vowel, the vowel input activation key 501, which is defined by an extension key, is first pressed, and then, when a different key is pressed, This input method is shown in FIG. 6. FIG. 6 (I) shows a case where, when the key 5, which is a vowel input activation key, is pressed, instead of the consonant characters originally designated in the surrounding keys 2, 4, 6 and 8 '' ',' '', '' 'And' ㅜ 'are assigned to keys 1, 3, 7 and 9 corresponding to each corner It shows the arrangement of vowels alternately specified. The peripheral key designation array of the vowels 'a', 'b', 'b', 't', 'a' and 'l' activated when the activation key of the vowel is pressed is not limited as shown in FIG. 5 (I) It is not a problem if the user or the manufacturer of the device adjusts it. However, as shown in Fig. 5 (I), the reason for designation is as follows: 'a' is arranged on the left side, 'ㅓ' is arranged on the left side, 'ㅓ' is arranged on the upper side, Quot; are intended to be construed as limiting the scope of the present invention. Therefore, there is no problem in arranging as shown in Figs. 6 (II) and 6 (III). Even if these hall vowels are arranged around the vowel input activation key in a form other than a cross, there is no problem. Furthermore, 'ㅢ', which is not a hall vowel, is also inserted in the vowel array, which is an example showing that it can be inserted as a way to eliminate the inconvenience of inputting 'ㅡ' and 'ㅣ' respectively.

In the case of the Korean vowel, it is possible to input the double vowel 'ㅑ', 'ㅕ', 'ㅛ', and 'ㅠ' in addition to the hall vowel shown in FIG. 6 Since this is not possible in the arrangement of the vowels shown in 6, it is possible to input these double vowels using the input activation key as follows.

The first method for inputting a double vowel is to input a double vowel by inputting a double vowel as shown in FIG. 7 (I) to be. ㅐ 'and' ㅔ ', which are not double seams but have more than three strokes, are located in the same direction as' ㅑ' and 'ㅕ' with 'ㅑ', 'ㅕ', 'ㅛ' 'And' ㅖ 'are located below' a 'and' ㅓ ', respectively, to facilitate user recognition. Figures 7 (II) and 7 (III) show possible arrangements for inputable vowels. Further, when the user presses the activation key of the vowel three times, it is possible to designate and arrange additional vowel groups.

However, since the number of such memories can cause inconvenience, it is possible to reduce the number of presses as much as possible and to arrange only the vowels having relevance. In the case of the double vowels, .

For example, as shown in FIG. 7 (I), in the case of 'ㅖ', it is possible to input by pressing the vowel input activation key twice and then pressing the key 9, but 'ㅕ' (see FIGS. 6 (I) and 7 (Refer to Figure 6 (I): Press the key once to activate the vowel input, then press the 3 key or 9 key. The user can select one of the two methods and select a convenient method according to the user.

In other words, a method of inputting 'ㅕ' and 'ㅣ' which can be recognized easily for a novice user is a method of directly inputting 'ㅖ' to a skilled person and a method of minimizing the number of key presses and a finger movement distance .

In the example of inputting "night" in the keyboard structure shown in FIGS. 6 (I) and 7 (I), the key press sequence is 6-5-5-4. Compared with the key press sequence 6-5-4 for inputting 'ah', the first 5th key press is a hall vowel input expansion function and the second 5th key press is a transition function from a single vowel activation state to a double vowel activation state .

In other words, when the double-vowel activation key is pressed twice by pressing the vowel input activation key, a double vowel corresponding to the designated key vowel vowel is designated and a double vowel is input instead of the vowel vowel if these keys are pressed. That is, in the case of 6-5-5-4 pressing sequence, "night" is input.

[5 - 5 - X] represents a single vowel 'a', 'ㅓ', 'ㅗ', 'ㅜ', ' , 'ㅛ', and 'ㅠ'.

[5 - X] (where 'X' is any key and [5 - X] constitutes one vowel if 'X' is not key 5, and if 'X' 5 - 5 - X], it is interpreted as a double vowel. Therefore, in the automata construction, the 5th key is composed of a key that is connected and pressed together with one key Key is interpreted to form the vowel input.

If the 5th key is pressed more than 3 times, the already pressed 2 key presses are extinguished and if it is interpreted as 1 key press, the function of the vowel input activation key is circulated in the order of the hall vowel-> Designation may be possible.

Otherwise, if the button is pressed three or more times, the third push may be used to turn the vowel input into an inactive state by destroying the vowel input active state. This is a way to correct consonant if the user accidentally presses the vowel input activation key by pressing the vowel input activation key twice so that the consonant input can be performed as a kind of cancel button.

When a vowel input is performed using the vowel input activation key of the present invention, when the actual vowel input activation key is pressed, the output unit 130 preferably displays a vowel input active state on the screen as shown in FIG. As described above, when the input unit 110 is implemented by using a keypad or the like, characters assigned to each key constituting the keypad and characters assigned when the extension key is selected can be displayed by printing or other methods, If the extension key is currently selected, that is, whether or not it is in the vowel input state, the user can input Hangul without any inconvenience.

That is, when the user presses the activation key of the vowel, if the user can distinguish the active state of the vowel input, such as displaying the background color of the pointer (cursor) from yellow to transparent, Since the key to be pressed can determine whether to input a consonant or a vowel. If there is no such indication of the vowel activation state, the user may be confused.

In particular, a method of distinguishing the active state of the hall vowel input shown in Fig. 8 (the background color of the pointer is set to yellow) and the activated state of the double vowel input shown in Fig. 9 (changing the background color of the pointer to red) The user can perform a more specific vowel input.

In FIGS. 8 and 9, although the input state is classified by changing the background color of the pointer, the shape of the pointer may be changed from a square bracketed form to a rectangular shape as shown in FIG. 8, It is possible to distinguish the input state through a method of displaying a state in which a hall vowel can be input when the number of squares is one and a state in which a double vowel can be input when there are two squares.

10 is a diagram for comparing a conventional input system with an input system of the present invention.

10 (III) shows the keyboard layout of the bar-entry system of the patent 10-0291838, and FIGS. 10 (I) and (II) introduce the concept of the expansion key And the vowel input activation key 701 of the present invention is applied after deleting the vowel leaving only consonants in the array to which the first letter is assigned.

At a glance, it can be seen that the four keys needed to input vowels in the input system are reduced to three, resulting in all 12 keys The keyboard layout of the present invention using only nine keys compared to the naked-character input system to be used, arranges the "stroke (additional stroke)" key and the "syllable" key in the keys 4 and 6, In terms of principle, can be dramatically reduced. The key input sequence for inputting the character 'land' will be described below with reference to a nail letter input system to which the present invention is applied, for example.

In the case of the text input system shown in Fig. 10 (III), the numeric key press sequence is as follows.

2 -> * -> # -> 7 -> 6

In this case, press key 2 to select 'ㄴ', press' * 'key to convert it to' ㄷ ', then press'' 'key to make' ㄸ ' And finally press key 6 to enter 'o' to enter 'land'. Assuming that the total number of keystrokes is 5 and the distance between the keys is 1, the moving distance of the finger calculated by the method shown in FIG. 10 is 9.63.

On the other hand, in the modified latent character input system to which the vowel input system of the present invention shown in FIG. 10 (I) is applied, the numeric key press sequence is as follows.

2 -> 4 -> 6 -> 5 -> 4 -> 9 (in the case of FIG. 10 (I)

In this case, press key 2 to select 'ㄴ', press key 4 to convert it to '' ', press key 6 to change' ㄸ ', press key 5 to select' And press key 6 in succession to enter 'a', then press key 9 to enter 'o' and you will enter 'land'. Assuming that the total number of keystrokes is 6 and the distance between the keys is 1, the moving distance of the finger calculated by the method shown in FIG. 7 is 7.8.

In other words, the number of presses increases by one, but the finger movement distance decreases by about 20%. This provides a way to input all alphabets as only nine keys in the keyboard structure shown in FIG.

In addition, since the Korean alphabet can be input by only 9 keys, additional functions can be added to the three keys in the case of the keyboard having 12 keys, resulting in a further increase in the efficiency in the whole aspect. For example, if you use the menu key or the move key to enter a space key, a period (.), Or a question mark (?) As a function of adding or subtracting # Key, * key, etc., and the convenience is further increased. This is because it is an element to be compared as an element necessary for inputting the actual sentence, not simply the number of presses and the movement distance of the finger required for the input of the Korean alphabet.

Furthermore, the advantage of the present invention is that the input of Hangul words is possible as nine keys, so that it is possible to input characters easily without having to look at the keyboard after the key board is learned, thereby bringing convenience of one hand together.

In the input system of the present invention, the characters allocated to each of the divided regions are set as characters excluding the vowel, and when the extended key as the vowel input activation key is selected, the characters assigned to the respective divided regions of the extended region include vowels Characters, or a vowel, it is possible to use a limited number of divided areas more easily, and the moving distance of the finger can be shortened.

(3-2)

11 is a diagram for comparing a conventional input system with an input system of the present invention.

11 (I) and 11 (II) introduce the concept of the extended key (vowel input activation key) of the present invention into this system, And the vowel input activation key 801 of the present invention is applied after deleting the vowel leaving only the consonants in the assigned array.

11 (III), the concept of the extended key (vowel input activation key) of the present invention is introduced into the keypad structure of the sky, thereby generating the necessary vowels for vowel entry as shown in Figs. 11 (I) and 11 (II). ) And the key corresponding to the person (ㅣ) are utilized for different functions. Accordingly, the consonant collision problem and the space key, which have been pointed out as problems of the Chinese character input system up to now, Can be applied.

In FIG. 11, the move key (the abbreviation key: No. 6 key) or the menu key (key No. 0) is disposed at the center of the keypad, thereby increasing the convenience for the user.

The problem of consonant collision, which is an uncomfortable element of heaven and earth, is that when the consonant corresponding to the consonant is input, pressing the 'consonance' key causes the input cursor to move to the next space so that the same key can be continuously input. For example, it corresponds to the 'move key' of the keypad input system of the sky key, and if it is pressed twice, it can also take the space key, which is the same as moving the 'move key' to the center of the keyboard.

For example, in the present invention, in order to input the word " in mind "

4 - 4 - 5 - 4 - 4 - 5 - 7 - 4 - 4 - 6 - 4 - 5 - 6 - 5 - 3

In case of Chungjin Hangul character input system, the key press sequence is as follows.

0 - 0 - 1 - 2 - 0 - 3 - 0 - 0 - (move key) - 0 - 2 - 1 - 1

In this example, the number of times to press the remaining keys except for the move key is larger in the case of the present invention. However, in the case of a wide-area input system, the user may wait for a long time to input a ' The movement distance is greatly increased since the user must press the move key located outside the area to which the keypad is assigned.

In other words, in the case of the wide-angle input method, a large factor that increases the moving distance is that the moving key is pressed due to the consonant collision. In the present invention, since there is no part occupied by the vowel in the initial keyboard layout, To the area to be processed.

Also, in the case of the wide-angle input system, the consonant 'ㅇ' and 'ㅁ' are assigned to the key '0' which is the farthest from the vowel, and the moving distance increases greatly in the above case. However, The shift key for the keypad is shifted to the key No. 6 in the center of the keypad and the keys for the vowel are not necessary so that the keys 'ㅇ' and 'ㅁ' assigned to the key '0' are assigned to the key No. 4, The center is adjacent to the center and the movement to the next key is always confirmed by touching the keyboard of the finger even if the keyboard is not recognized by the eyes. Therefore, not only the input speed is increased but also the character input is performed by only the thumb joint movement Convenience is added. This is a prominent advantage of the 9-key input method as in the present invention.

In Examples 3-1 and 3-2 described above, when compared with the two typical character input methods, that is, well-known character input method and rough character input method, the configuration of the present invention is such that a key, Instead of being separate, I assigned the consonant and vowel together in the same key, and activated the vowel by the extension key.

In the conventional case, due to the characteristics of Korean, Korean, and Korean characters, which are composed of consonant, consonant, and neutral vowel, the key is divided into right and left or up and down. In the present invention, since the consonant and the vowel are not arranged in a separate arrangement, the distance movement for inputting the initial, neutral, or neutral ending is relatively reduced, and the finger movement is significantly reduced as compared with other Hangul input will be.

FIG. 12 shows the number of pushes and finger movement distance data for Hangul input methods which are typically applied to a mobile phone marketed on the Internet (http://rock1209.tistory.com//296). As can be seen, in the case of the keyboard shown in Fig. 11 of the present invention, the finger moving distance is shorter than any other method.

This is easily understandable from a principle point of view because it is possible to input with 9 keys. Fig. 12 shows this fact as an intention of the present invention.

In the case of the present invention, the number of presses is 37 (although there is an error in the data of FIG. 12) even if the movement distance of the finger is shortened even if the number of presses is the same, , And the finger movement distance is 37.2 (+ alpha; where alpha is the distance that the finger moves to press the move key due to the consonant collision), the press number and movement distance are 10% and 20% %, Which proves to be less convenient than when using the keyboard of the present invention.

It can be seen from the data of FIG. 12 that the ease of use increases when any understanding of the vowels is achieved, than any keyboard layout now. In particular, FIG. 12 shows the reason why the average moving distance of the finger (the distance of movement of the fingers accompanied by the one-pressing operation) is comfortable for Samsung's method of entering the sky. In other words, in the case of the letter input method of Samsung, the distance that the finger should move after moving the key once is moved only by one key, so that it is convenient to find the key easily. On the other hand, Since the average moving distance is twice the distance between the kiwans, it can not be found easily, which makes it difficult. On the other hand, in the present invention, the average moving distance is 0.86, which is smaller than 1, indicating that it can be found more easily than the character input of the sky. In other words, it shows the reason why the user can input characters with 9 keys. Ergonomically, 9 keys can take the entire key only by the joint motion of the thumb, thereby enabling the user to input without looking at the keyboard.

Hereinafter, an example in which an additional function can be introduced into an input system having a limited number of divided regions by excluding a vowel in the firstly arranged character is as follows.

[Example 4]

(4-1)

In this embodiment, one or two consonants are assigned to each key in consideration of the number of actually used consonants, which is related to the consonant arrangement to which the vowel input method of the present invention is applied. If possible, ) Designates a large consonant as a main character and inputs each key when it is pressed once. The order of the consonants is arranged in the order of consonants in the Korean alphabet so that the user can easily understand them.

Thus, the arrangement of the consonants is 1, 2, 3, and 6, respectively, as shown in FIG. 13, in the order of 'a' 'c', 'd', 'o k', 'c', ' , 7, 8, and 9 keys. In addition to these consonants, the function necessary for inputting 'hyphen' is assigned to key 4 to allow all consonants to be input. If you press the 9th key with 'ㅎ' with your finger, it is unnatural compared to other keys. If possible, you can specify 'ㅅ' and 'ゃ' in the 8th key in the middle of the keyboard. There is no difference but only the difference that the number of presses increases by one for the input of 'i', so that if possible, 'i' is placed in the center column of the keyboard.

Likewise, in the case of the key # 7 designated by the letter 'ƒ', only one letter is designated for the same reason as the key # 9, thereby facilitating the input.

And 격, ㅌ, ', and' are designated as the last characters in the keys designated as 'a', 'c', 'ㅂ', and 'ゃ' respectively. In the case of 'ㅋ' and '' ',' '' and 'ㅈ' are input by pressing the keys 1 and 7 twice, When the specified key 2 and key 8 are pressed three times, the input is made. In this case, the condition for inputting all consonants is satisfied as nine keys, so that the input of the Hangeul character is easily performed with one finger.

(4-2)

In order to prevent the occurrence of a consonant collision that should be entered as the first letter consonant and the second letter consonant as in 'each case' as in the above embodiment (4-1), 'move key' In order to prevent the finger from moving to the move key by assigning the corresponding function to the separate key, the 'ㄱ' and the 'ㄷ' specified in the second key are separated and the first key and the ' 15 shows a consonant arrangement method for assigning a function 'move key' to a key No. 2 to which a 'd' is assigned to a designated key 3 and a '2' key to which a 'c' and a 'c' are assigned.

The vowel arrangement applied in the case of the consonant arrangements of Figs. 13 and 15 corresponds to Figs. 6 (II) and 7 (II). If 'a' and 'c' are separated and combined with 'a' and 'd', if the increase of the number of pushes is expected as much as possible, a method of separating 'b' from ' To the fourth key (indicated by ' ** ' in Fig. 13 (I)) for performing the horn function.

In the case of a real consonant collision, it is more rare than when each key is used. Therefore, when the percussion function key is pressed twice, the operation of pressing the two times by giving the function of the move key does not greatly affect the total number of key presses, The second highest 'c' can be specified as the first character of the key.

The consonants 'a', 'c', 'f', 'g', and 'i' are all arranged on the left side. So that the finger moving distance can be reduced. Likewise, the reason why 'ゃ' is assigned to the same key as 'ㅅ' is that it is advantageous to designate only 'ㅎ' in the key 9 as described above. Another reason is that you only specify 'he' in key 9.

The '**' in charge of the sound function does not merely translate the transcoding function that converts 'A' into 'ㄲ', but the consonant collision occurs when consonants of consonants and consonants of next consonants are assigned to the same key As well as a function to prevent the occurrence of the problem. For example, in order to input the word 'go', in order to input 'c' of 'kanji' and 'c' of 'kanji', it is necessary to input 'b' in the keyboard structure of FIG. 13 and then press the move key. The '**' key is responsible for the function. That is, the key press sequence for inputting 'go' is as follows.

1 - 5 - 4 - 2 - 4 - 2 - 5 - 4

('A' + '+' + 'ㅇㅁ' + 'c' + '**' + 'c' + '+' + 'ㅇㅁ')

'*' Is indicated twice, which means the same consonant repetition in the transcription conversion function, but can be understood as meaning to input an additional consonant when the function as a movement key for preventing consonant impulse is performed. If the consonant is followed by the same consonant, pressing the '**' key will produce the same effect.

In the case of 'go' above, 'ㄱ' means that there is no consonant corresponding to the punctuation, so you have to press the '**' key once. But if you use 'ㄱ' '**' is input by pressing '**', pressing '**' once causes an error. Therefore, if you want '**' to take charge of the consonant collision prevention function and the transducing function, press '**' once to take charge of the prevention of consonant and leading consonant collision, So that it is possible to prevent a case where two functions such as 'each' are possible at the same time.

Accordingly, the function of the '**' key is to constitute the function of the longitudinal, consecutive consonant collision prevention function and the transposition conversion function according to the zooming once or twice.

(4-3)

Unlike the above embodiment, by taking advantage of the specificity of 'ㅇ' among the Korean consonants, the function of '**' in FIG. 13 and FIG. 15 having the above-described configuration of the double consonant function is handled, More.

At the time when Hangul was created, 'ㅇ' was divided into 'ㅇ' and '字', and 'ㅇ' was used as a component to maintain vowel shape without substantial sound. In other words, 'ㅇ' is not used between consonants and consonants. The use of this point is at the heart of this configuration.

That is, in the case of inputting 'each' in the keyboard layout shown in FIG. 16, there occurs a problem in which the first syllable 'urn' of 'angularity' and the first syllable 'A' In this case, to input the first 'ㄱ', press key 1, then press key 4, then press key 1 again to input 'a' twice.

If you press key 1 twice consecutively without pressing key 4 corresponding to 'ㅇ', you will enter 'ㅋ' instead of typing 'a' twice. Therefore, between consonant and consonant There is no practical input of 'ㅇ' and it is only the role of the move key to avoid collision of consonants. Further, if the fourth key corresponding to 'ㅇ' is pressed twice between the consonant and the consonant, the first consonant is sounded to input the consonant.

Since 'ㅇ' is never input between two consecutive consonants and consonants, it allows not only the function of the move key but also the function of inputting a double consonant. For example, the key press sequence for inputting 'fast' in the keyboard layout of FIG. 15 is 7 - 4 - 4 - 5 - 6 - 3 - 4 - 3 - 6, where the first syllable ' The second syllable 'd' is the same as the first syllable 'su', so that the third syllable key can not be pressed in succession. Press key 4 in the middle of the input to complete the input. Since this method does not hinder the input of 'o' at all, it is necessary to press the activation key of the vowel in the keyboard layout shown in FIG. 9 by using the 'o' Allowing the vowels 'ㅣ' and 'ㅡ' to be used with consonants. Therefore, in case of 'ㅣ' having the highest frequency of use among the vowels, it is possible to input a single pressing operation, thereby increasing the efficiency of the input due to the reduction of the number of input. In addition, the positions where 'ㅣ' and 'ㅡ' are arranged in the keyboard structure of FIG. 9 are designated as' '' and 'ㅓ', 'ㅓ' 'And' why '(1503), as shown in FIG. 16 (III), can be input by two pushing operations, And the input efficiency becomes much higher because it is input by three pushing operations.

(4-4)

According to another embodiment of the present invention, a consonant collision occurs in a case where a plurality of consonants are assigned to one key and are sequentially inputted in the order of pressing, Is assigned to the same key) is a consonant arrangement method.

To this end, a separate function key is designated in the present invention. The function of this select function key allows you to select the remaining non-uppercase letters for each key.

In the keyboard layout shown in FIG. 17 (I), only the uppermost letters are displayed on each of the keys. When the respective keys are pressed, the uppermost letters are input. And then pressing the key of the key.

For example, to enter 'ㅋ', press 'A' key and then press '*' key. Likewise, in case of 'ㄲ', press 'A' key and then press '*' key twice in succession. Therefore, in the keyboard layout shown in FIG. 17 (I), the upper and lower letters assigned to each key are as follows. The characters in parentheses are arranged in order as non-uppermost characters.

    Key 1 - Key 2 - Key 3 - Key (,, ㄸ)

    Key # 3 - Key # 6 - Key,

    Key 7 - F, Key 8 - Key 9 - C,

                          Key 0 - ㅇ (heh).

In the case of a keypad mobile phone having twelve keys, the selection function key can be assigned to the (*) key or (#), which can be determined according to the convenience of the user. In the case of the keyboard having the consonant arrangement, the input of Hangul is already described in the case of the keypad mobile phone in Embodiment 2, and the case of inputting consonants is as described above.

[Example 5]

(5-1)

In the case where the input unit 110 of the present invention is constituted by a device for sensing the touch of a user such as a touch pad or a touch screen, the present invention can input the initial value and the neutral value by one touch and drag. That is, consonants and vowels can be input simultaneously as syllables.

In the case of FIG. 13, for example, in a conventional keypad mobile phone, the user presses the first key corresponding to 'A' to input 'a', and then presses the fifth key having the vowel input activation function And then press key 4 to enter 'A'.

In the case of an input device composed of a virtual keyboard using a touch sensor as compared to such a keypad mobile phone, in order to input 'a', touch the area of the key 1 and then hold the hand in touch with the touch sensor Move to the 5th key area to activate the vowel input activation function, then move to the 4th key area and then move the finger away from the touch sensor (screen for the touch screen mobile phone) to be.

In this case, three touch operations are replaced with one touch operation, resulting in a dramatic increase in the input speed. If you want to input 'Da' by using the syllable input method, touch the 2nd key area once and then touch the second time. Then, do not separate your hand from the touch sensor (screen for touch screen mobile phone) Moving to key area 5 and activating vowel input, moving to key area 4, and then separating the finger, the input of 'D' is completed.

In other words, in a state in which the first character of the Hangeul character is selected, it is possible to select a desired vowel as it is without separating the finger from the touch sensor.

In the case of a single vowel, after the consonant is selected, the vowel input is activated in the touch state. After the finger is moved to the key region corresponding to the single vowel, the syllable having the composition of the consonant +

However, in the case of a double vowel, unlike a single vowel, input is impossible with a single stroke. Therefore, in the case of such a double vowel, first, in order to activate the vowel input without moving the finger while keeping the consonant selected, move to the key area No. 5 and then release the hand to make the double-vowel input activation state, and touch the area corresponding to the double- Once you release your finger, the input of the double vowel is completed.

For example, in order to input 'Ya', touch the key No. 6 corresponding to 'ㅇㅁ', move to the key area of No. 5, move the finger away from the touch sensor, Touching and touching it will separate the input. That is, in the case of 'Ya', the stroke has the same stroke as the case of the single vowel 'A', but only the operation to cut off in the key area of the middle 5 is possible so that the input of the double vowel can be easily performed. This example merely shows that the vowel arrangement of the present invention is capable of simultaneously inputting a consonant + vowel by a stroke method. Therefore, in order to input the consonant of the present configuration in the character input method using the virtual keyboard, it is the content of this configuration that the consonant input is completed without the finger being separated from the touch sensor.

(5-2)

An input method combining Example 5-1 and Example 4-4 is shown in Fig.

As shown in FIG. 18, when the first letter 'ah' is input, the 'o' starts with the finger touching the 'o' key, and the 'a' ㅁ 'key area and then separates the finger.

In the case of 'a', start with the finger touching the 'a' key, move through the vowel activation key (+) area, reach the 'k' key area designated 'a', and then separate the finger.

Finally, in case of 'Mr.', touch the 'ㅅ' key, then move the finger away, and touch '*' key to change the input character from 'ㅅ' to 'ㅆ' If you move to the 'ㄷ' key area through the vowel input activation key (+) area and the 'ㅣ' key, and then move your finger away, the input of 'Mr.' will be completed.

In FIG. 18, the black circles indicate touch-spacing (the black circles represent the 'touch-spacing' operation in the case of a touch screen and the pressing operation in the case of a keypad) The starting point of the curve indicating the movement path in contact with the touch sensor is the point at which the contact starts, and the point where the arrow is located indicates the last point at which the finger is disconnected.

(5-3)

FIG. 19 compares another method of inputting 'night' with that of the keypad.

In the first method, as shown in FIG. 19 (I), after touching the key 'ㅇ', the user presses the vowel input activation key twice through the touch-separation process (② and ③) 'Key to touch-off (④) to complete the input of' Night '. Here, the process of inputting 'night' in the keypad mobile phone is the same as that of FIG. 19 (I) because the touch-spacing process is the same as the push-apart operation in the keypad mobile phone.

However, the curved line with arrows 19 (II) to (V) means a movement in the state where the finger touches the touch sensor, so it can not be applied to the keypad, and is useful only for the virtual keyboard system using the touch sensor. The process (1) of FIG. 19 (II) is the input of 'o', the process of the short vowel activation process, and the process of the double vowel activation process. If the 'ㅁ' key is touched after the step ②, 'a' is inputted if the step is separated. This is because the first contact point in the step ③ is the vowel input activation key region. It has the same effect as the simultaneous execution. Therefore, the touch-spacing process is omitted once, thereby increasing the input efficiency.

Likewise, the process (1) of FIG. 19 (III) has the same effect as the processes (1) and (2) of FIG. 18 (I) It will have the effect of omitting two touch-spacing processes.

[Example 6]

(6-1)

As with consonants, vowels can be double-vowelized using the selection function keys.

FIG. 20 illustrates this embodiment. In this case, when the input of 'ah' and the input of 'night' are performed through the same trajectory and touch-spacing process and in the case of ' .

In order to allow users to input a vowel with the same mechanism as the consonant selection, 'ah' and 'ya' input are subjected to the same trajectory and touch- 19 (I) to (III), it is possible to correct only the process of touching the selection function key without changing it from the beginning even if 'A' is inputted in the process of FIGS. To provide a solution.

17, when a region of the selected function key is touched and separated after inputting the short vowel sound as shown in FIG. 17, a '?' Or '?' Is inputted as a method for inputting the corresponding double vowel, Touch 'key area', 'ㅢ' will be input, ''',' ㅓ ',' ㅗ ',' ㅜ '',' ㅛ ', and' ㅠ ', respectively. The finger movement in the touch state indicated by the curved line in FIG. 19 is not applicable to the keypad mobile phone. However, when a vowel activation key is touched once using the '*' key (FIG. 17 (I) (The group of vowels shown in Fig. 17 (II)) when the user touches the vowel group twice (i.e., the vowel group shown in Fig. 17 (II)).

[Example 7]

(7-1)

Embodiment 7-1 of the present invention is a method in which the vowel input activation key region is considered to be touched three times or is touched three times instead of a combination of short vowel + short vowel or double vowel + And provide a way to enter.

As shown in Figs. 21 (I), (II), and (III), when the vowel input activation key is touched once, a short vowel group (a, b, c, t, (I)) can be selected by touching twice, and a double-tone group (ㅑ, ㅕ, ㅛ, ㅠ, ㅢ, ㅖ, ㅒ, (ㅚ, ㅘ, ㅙ, ㅟ, ㅝ, ㅞ, 6 characters - Figure 21 (III)) can be selected by touch. As shown in FIG. 21 (I), consonants are arranged around the vowel input activation keys and unlike the selection function keys 1602 in FIG. 17, consonants are input in a multi-tap manner in the consonant arrangement of FIG. ) Key 1902 serves as a move key for preventing a consonant collision, it is possible to reduce the number of touches of the vowel input activation key by combining the key with the vowel input activation key.

That is, it is not necessary to touch the vowel input activation key three times to input a vowel group belonging to the diphthong group of FIG. 21 (IV). If the user touches the (*) key and touches the vowel input activation key 1901, So that the vowel group can be selected. As a result, the (*) key 1902 corresponds to the double touch of the vowel input activation key 1901, thereby reducing the number of touches.

This is also applicable to the keypad cell phone, which means that you can press the key twice to activate the vowel input activation key three times (one key (*) + one key activation key) .

In FIG. 21, the function (*) in FIG. 21 performs the function of the movement key to prevent the consonant collision, so (*) executes the movement of the input space between the consonant and the consonant (*), It is not the movement, but the function that presses the activation key of the vowel twice.

However, even if the virtual keyboard input method using the touch sensor (*) touches the key, the group of diphthongs should not be displayed on the screen until the user touches the vowel input activation key. And may be input. If the (*) key in FIG. 21 corresponds to the selection function key 1602 as shown in FIG. 17, the (*) key can no longer have the effect of touching the vowel input activation key twice.

This is because when the (*) key is responsible for the function of the selected function key (*), it is necessary to touch the vowel input activation key for the short vowel input after touching the key, so that the short vowel input and the double- This is because the inconsistency of implementing the two functions occurs in the same process.

22 shows an array structure of vowels when the keyboard layout of FIG. 21 is changed to the landscape mode. In the keyboard layout arrangement of FIGS. 21 and 22, the vowel input activation keys 1901 and 2101 have a separate menu key existing on the virtual keyboard using a touch sensor, such as a period, a comma, and a question mark 21 (II) and 22 (II) without touching it with a finger to call up the symbol input key board, these punctuation symbols are displayed in a state of touching the short vowel It will provide a way to select and enter at the same time.

In order to input '?', '.', ',' In the case of a keypad mobile phone, the user presses the vowel input activation key and then presses the 'o', 'o', and ' If you press '' ',' '', 'ㅎ' key, the sentence symbol will be input instead of these consonants.

(7-2)

Embodiment 7-2 of the present invention is used in a method of reducing the number of times of pressing the vowel input activation key (the number of touches in the case of a virtual keyboard using the touch screen) of the diphthong input method provided in the configuration of Embodiment 7-1 A method of using the vowel input activation key instead of the " * " key is provided.

As shown in FIG. 23 (III), in order to input a double vowel, after inputting a single vowel instead of pressing the vowel input activation key twice in succession (in the touch screen mode, two touch-spacing operations) If you input a double vowel by pressing the vowel activation key once more (③), you can input a double vowel.

However, if you enter the double vowels ('ㅑ', 'ㅕ', 'ㅛ', '' ',' ㅢ ',' ㅒ ',' ㅖ ') in the method of Figure 23 (III) It is impossible to input each short vowel continuously. For example, if you want to input 'ㅗ' and 'ㄱ' to input 'ㅘ', you should input 'ㅛ' and 'ㅁ' instead of 'ㅘ' It is to be brought.

In order to input 'ㅗ', press the key input activation key in the keyboard shown in FIG. 23 (I), press the key 'c', and then press the vowel activation key and the key 'k' This is because the action of pressing the key input activation key for inputting the 'a' brings the action of changing the already inputted vowel 'ㅗ' into the double vowel 'ㅛ' instead of bringing the vowel input activation, ㅁ 'is to input the consonant' ㅁ 'as it is.

23 (IV), in the case of the diphthong tone, it is possible to input the diphthong tone as a method of selecting the divided region to which the corresponding diphthong tone is allocated by pressing the vowel input activation key twice in succession desirable.

(7-3)

In order to increase the intuitiveness of the arrangement of the user's diphthongs, in the case of the diphthongs input, there may be a method of pressing all the short voices constituting the diphthongs even if the number of presses is increased.

For example, the configuration of the automata may be changed as shown in FIG. 23 (IV) to FIG. 24 (IV-1) in order to input 't' and 'l' to input 'ㅟ'.

In other words, if the user presses the activation key of the vowel twice, the two pushing keys to be pressed afterward are all to input the character corresponding to the vowel.

[Example 8]

(8-1)

In Embodiment 5, an example has been shown in which an input can be easily performed by one touch and drag operation when inputting initial and neutral.

In the above embodiment 5, although only the case of the neutral group is taken as an example, it is possible to input the similar operation even in the case of a double voice such as 'ㅘ, ㅝ, ㅟ,., ㅢ, ㅞ, ㅚ'.

The fifth embodiment and the seventh embodiment will be described below.

The key pressing method applied to the keypad keyboard of FIG. 23 can be directly applied to the touch screen, and FIG. 25 illustrates the use of the key pressing method until the drag operation to reduce the number of touches.

FIG. 25 (II) shows that two touches can be replaced by one drag operation by inputting 'a' in the same manner as FIG. 23 (II), and FIG. 25 (III) And 'ㅠ' is inputted as a touch-spacing operation.

Furthermore, FIG. 25 (III-1) shows that all the double voices can be input by one drag operation. However, FIG. 24 (III-1) has a higher probability of occurrence of an error as compared with FIG. 24 (III).

This is because the end point of the drag operation is clear in Fig. 25 (III), so that the single vowel is accurately determined and accordingly the double vowel is also accurately determined. However, in FIG. 25 (III-1), there is an advantage that the operation is not interrupted. However, during the finger dragging operation, not only 't' but also 'ㅓ' and ' And it is not preferable that the locus of the finger is inaccurate.

25 (IV) shows that the input of the diphthong tone is completed by a drag operation after one touch-spacing operation. The feature is that the input diphthong is a combination of the first vowel corresponding to the start position and the end position of the drag operation .

(8-2)

26 shows an example of inputting 'O' (I), 'Yo' (II), (II-1), and 'Why' (III) by dragging when the vowel arrangement by the expansion key is as shown in FIG. 26 (II) and 26 (III) show the input process of "why", and FIG. 26 (II-1) And inputting 'o' in order to input a double vowel 'yo', and then inputting 'yo' by touching-away the vowel input activation key again.

26 (II) is compared with FIG. 26 (II-1), the locus of the finger shown in FIG. 26 (II) is more accurate than moving from the vowel input activation key region to the ' The finger trajectory of FIG. 26 (II-1) may be interrupted with a process of inputting a 'Ya' or a process of inputting a ' Even if the 'ㅣ' key area is used, since the finger input is separated from the 'ㅗ' position and the 'o' is input correctly and the vowel input activation key is touched again, more accurate input is possible.

Unlike the double vowel, the advantage of the double vowel sounds is that the end point of the drag is clear, so the point passing through the middle is not a big problem. For example, when 'why' is input as shown in FIG. 26 (IV), not only 'ㅗ' but also 'ㅣ' and 'a' are passed through during the drag operation. Since the end point corresponds to 'ㅐ' The input error that may occur in Figure 23 (III-1) does not matter.

The advantage of the drag operation as shown in FIG. 26 is that it is possible to omit the 'touch-spacing' process so that all the vowels can be input by one drag operation. FIGS. 27 and 28 show such an input method .

27 differs from FIG. 28 in that the consonant and vowel arrangements are in the vertical mode and the horizontal mode, but the input method for the short vowels, the double vowels, and the double vowels is the same except that the direction is changed by 90 degrees.

As described above, the 'consonant' + 'vowel' input method according to the present embodiment provides a method of inputting Korean characters easily by one drag if only the positions of the eight single vowels are known, The area of the key is specifically defined, ensuring accurate vowel input.

The input analysis unit 120 of the present invention may be configured such that (1) when the user performs a drag operation on the input unit 110, all the characters assigned to all the divided regions contacted during the drag operation are selected; (2) It may be considered that only the characters assigned to the divided area determined to have contacted by a predetermined width or more are selected.

In addition, it can be regarded that only the characters that can make letters when inputted in order among the characters assigned to all the divided areas contacted during the dragging operation are selected; or 4) The character assigned to the divided area may be regarded as being selected, and the character assigned to the intermediate contacted area may be selected only when the character is selected between the first selected character and the last selected character.

At this time, the first selected character may mean the first selected character to input the leading or neutral. In the case of neutral, the activation key or the vowel input activation key, which is an extended key, can be displayed as the first selected character after the first contacted key is touched.

When the input analyzing unit 120 makes a judgment based on the method 3), in order to input the diphthongs at a time in a drag manner, it is important to arrange the vowel keys to prevent misunderstanding as much as possible.

For example, if you type 'why' in the previous example and 'ㅣ' at 'a', you may be uncertain whether 'ㅚ' or 'ㅙ' is entered.

In order to minimize such misunderstandings, eight vowels of a short vowel corresponding to the vowel input activation key are arranged, namely, a, v, ㅗ, ㅜ, ㅡ,,, ㅐ and ㅔ. , And in order to input the diphthongs, 'ㅗ' and '' 'should be placed in the corner area of the square area where the vowel is arranged as shown in FIGS. 27 and 28.

If 'ㅗ' and 'ㅜ' are placed in the corner area, it is impossible to display the diphthong by the combination of short vowels displayed on the screen. 30 (I) of FIG. 30 shows a case in which 'ㅗ' and 'ㅜ' are arranged at the corners. In order to input 'o' and ' Is selected, the vowels that these trajectories can make are only 'o' and 'ooo'.

On the contrary, when 'ㅗ' and 'ㅜ' are arranged in a non-edge area as shown in FIGS. 30 (II) and 30 (III), a character input This leads to a contradiction in the construction of the automata.

For example, Fig. 30 (II) shows the movement of a finger inputting 'ㅣ'. Actually, the trajectory of (1) actually selects' i 'region without going through' Is completed. However, since the probability of having the trajectory of (1) is close to '0' (zero), the movement of the finger actually draws the trajectory of (2) out of the trajectory of (1). In this case, since the unintended 'ㅚ' is input, there is no way to actually input 'ㅣ'. If the trajectory specifies to input 'ㅣ', the trajectory for inputting 'ㅚ' And it is necessary to create another trajectory. This is because it is difficult to get out of the intuition that the input method of the diphthong should be a trajectory connecting the short vowels constituting the diphthong. And it is inconvenient to know how to use it again if the user does not remember or memorize it.

30 (III). In the case of the vowel "ㅗ", there is no problem as shown in the traces 1 and 2 in FIG. 30 (III) The trajectory for inputting 'I' overlaps with the trajectory for inputting the 'up' sound as shown in the trajectory ④ of FIG.

Therefore, in the case where the arrangement of the short vowels as shown in FIG. 30 (II) or FIG. 30 (III), in particular, 'ㅗ' and 'ゅ' The trajectory for the input of the diphthongs including 'ㅗ' and 'ㅜ' can not be composed of the trajectories connecting the respective short vowels constituting these diphthongs.

In addition, 'ㅢ' is regarded as a diphthong and it can be input as a trail connecting 'ㅡ' and 'ㅣ'. For this, 'ㅡ' corresponds to the first short vowel that constitutes the diphthong, so 'ㅗ' and 'ㅜ' Should be placed in the corner area. However, as shown in FIG. 30 (I), if the light emitting diode is disposed at a position facing the light emitting diode (LED), no problem arises even if the light emitting diode is not disposed in the corner area. In the case of 'ㅡ', since there is no short vowel constituting the diphthong, there is no problem if a short vowel other than 'ㅡ' is placed in the key region adjacent to 'ㅡ'.

However, in contrast to 'ㅡ', 'ㅗ' and 'ㅜ' should be avoided not only in 'ㅣ' but also in 'ㅓ' and 'ㅔ' for 'ㅜ', 'a' and 'ㅐ' for '가' 'ㅗ' is not adjacent to 'a', 'ㅐ', 'ㅣ', and 'ㅜ' is also adjacent to 'ㅓ', 'ㅔ', and 'ㅣ' because there are three vowels to avoid each. There is no way to place it so that it does not. In other words, if 'ㅗ' and 'ㅜ' are placed on the corner at the same time, 'ㅗ' and 'ㅜ' should be placed in the corner area unlike 'ㅡ' When inputting the diphthong with the drag operation, it does not cause collision with the trajectory of entering the short vowel.

Inevitably, if only one of 'ㅗ' and 'ㅜ' is placed in an edge area, it is also not a problem if a vowel which does not constitute a diphthong is arranged in the key of the adjacent left or right or upper and lower area.

However, when only one of 'ㅗ' and 'ㅜ' is arranged in the corner area, the drag operation for inputting the diphthong tone is not performed on the straight line as shown in FIG. 27 (IV) and FIG. 28 (IV) It will not fail, but it is not a fundamental problem. Accordingly, this configuration provides a method in which all consonants and vowels can be input by a single touch when the finger moves along consonants and vowels displayed on the virtual keyboard in the touch-type input device.

29 shows that the above-described drag input method can correspond 1: 1 to the pressing operation of the keypad as shown in the second embodiment of the present invention, and the respective numbers are the order of the pressing operation.

(I), (II) and (III) of FIG. 26 correspond to the single vowel ('o'), the double vowel (' (II) and (III). 26 (II) and 26 (II-1), the keypad pressing operation is performed in the same manner. Conversely, in FIG. 26 (III), the keypad pressing operation is shown in FIGS. 29 (III) and 29 And two cases. Fig. 29 (III-1) corresponds to the configuration in Fig. 23, and Fig. 29 (III) shows the method according to the configuration in Fig. 24 (IV-1).

[Example 9]

Embodiment 9 provides a method of simplifying vowel input by assigning a vowel input activation key to two keys.

31, when the arrangement of the keys is elongated in the left and right direction, movement of the finger for inputting the vowel is inconvenient when the vowel input activation key is one. Therefore, in order to overcome this problem, 31, it is possible to minimize the movement of the finger (thumb) by using both hands (both thumbs) naturally when the key arrangement is performed as shown in FIG. 31, thereby facilitating easy input will be.

Furthermore, the consonant selection keys are arranged in the left (2903) and right (2904) to facilitate selection of the non-augmented characters assigned to each key, and the '@ (2905)' key in the middle can perform various functions have. For example, you can use 'space' or 'cancel' key, or you can use it as a menu key to add various functions by adding extended functions.

[Example 10]

Embodiment 10 relates to an example of determining whether or not an extended key is selected according to a gesture of a user without allocating an extended key to a specific divided area.

For example, when a consonant is input, when the first touch sensor is touched at first, a predetermined straight line distance is moved and then separated, the function of the vowel input activation key is taken. (This straight distance corresponds to the radius of the circle centered on the first touch point, and the outer circle area made of this radius becomes the vowel input activation area.)

The selection of consonants consists of the letters assigned to the keys of the virtual keyboard corresponding to the positions of the first finger touching the touch sensor. In this state, when the finger is separated as it is, the selected consonants are input, A certain distance from the first touching position (if this distance is too short, the collection input window can be activated for the accidental finger movement, and if the distance is too large, it becomes inconvenient to activate the collection input window, so that it can be changed according to the convenience of the user. ) Is moved and then separated, the vowel input window is activated and the vowel input can be executed.

This will be described as the keyboard layout of FIG. As shown in the consonant input window of FIG. 21 (I), when 'solver' is input using only one finger, if there is no such configuration, the user touches the touch sensor area designated ' The finger must go to the vowel input activation key to activate the vowel input window (Fig. 21 (II)) and then experience the inconvenience that the vowel 'ㅐ' must return to the designated area.

However, with this configuration, if you simply touch 'ㅎ', move your finger to the key area designated 'ㅐ', move it away from the touch sensor, and then touch 'ㅐ' It will be possible. (However, in this case, the finger movement distance for activation of the vowel must be set to be smaller than the distance from the designated area to the specified area.

Further, this configuration provides a method of simultaneously inputting the consonant specified in the left area of the touch sensor and then using both hands to input the designated vowel in the right area of the touch sensor, thereby simultaneously increasing the convenience and efficiency of the input .

If this is not the case, it would be inconvenient to move from the left to the right or from the right to the left with the finger touching the touch sensor.

For example, if you want to enter 'dog', touch the upper left area designated 'A' with your left thumb, move it further than the straight line movement distance to activate the vowel input window, 'Is touched, the input of' ㅐ 'is completed. Similarly, if you want to enter 'D', you do not have to move a lot of distance to the 'ㅔ' designated area through the vowel activation key to enter 'ㅔ' after typing 'ㄷ' Touching the 'c', move the distance corresponding to the radius of the vowel input activation, and then move the vowel input window when it is separated, it is inconvenient to use a single finger to move a long distance by touching the 'ㅔ' area with the left thumb Can be eliminated.

Therefore, according to the present invention, when a character is input, the movement distance of the finger is reduced, and at the same time, the finger movement distance is further shortened using both hands.

[Example 11]

In the above embodiment, only the example in which no character is assigned to the vowel input activation key, which is an extended key, and only a function of assigning a new character to the extended area is described.

However, it is also possible to assign a specific character to the extended key, and an example thereof is described in the eleventh embodiment.

 In Embodiment 11, the extended key is allocated to the divided region corresponding to the consonant '?', So that? 'Is input in the step of inputting the consonant, and the function of the extended key is performed in the step of inputting the vowel.

Specifically, the input of the vowel is performed according to the locus generated by the finger around the key region designated by 'k?' As shown in FIG. 32, and the method is based on the principle shown in FIG. 27 and FIG. In the case of consonants, each key region is input by a touch-spacing operation.

However, in case of light and shout, after inputting the terminal sound of the corresponding consonant such as' ㅋ 'and' ㄲ ', touch' umpun, Can be converted into 'a'.

32, in order to input 'a', the 'A' key region is touched and the finger is moved to the 'K' key region. When the vowel keyboard is activated in this state, the 'a' key region 'And' a 'are input at the same time, the input of' a 'is completed. That is, if the finger touch starts from the consonant and passes through the 'ㅁ' key area and is separated from the desired vowel key area, the consonant corresponding to the first key region and the last selected vowel (in the case of the double vowel or double vowel, Which is determined according to the movement of the finger in the finger.

However, in case of 'ㅁ', only 'ㅁ' is input when touching the 'ㅁ' key area and then separated from the position. If you want to input like a vowel, You can move your finger to the vowel key area on the keyboard and then release it. Accordingly, when the position touching the touch sensor for the first time is the 'ㅁ' key area, 'ㅁ' is inputted. However, if the user touches another consonant key area and moves to the 'ㅁ' key area, 'ㅁ' The user can not use the 'ㅁ' key when inputting only a vowel. Therefore, even if a user touches the vowel key by placing a separate vowel key 3101, the vowel key is activated and only the vowel is input There is also a way to do that.

[Example 12]

In the twelfth embodiment, a case where each key performs the function of an extended key will be described.

That is, although only the vowel input activation key has been previously described as the expansion key, in the twelfth embodiment, an example in which the divided region to which each consonant is allocated performs the function of the extended key will be described.

A plurality of character sets are allocated to each of the divided areas, and when the user selects a specific divided area, a plurality of characters allocated to each extended key are allocated to each of the divided areas belonging to the extended area set in the extended key of the divided area will be.

At this time, no characters may be allocated to the partition to which the extended key is allocated (i.e., not included in the extended area), and characters such as other extended areas may be allocated (i.e., included in the extended area).

FIG. 33 shows an example in which a character is allocated to a divided area to which an extended key is assigned.

33, each of the divided regions is configured such that the loudness and the trembling are assigned to one extended key, and '?' Is also configured to perform the function of the vowel input activation key as in the eleventh embodiment.

In order to distinguish the consonant input from the vowel from the vowel input, the consonant corresponding to the light and shout sounds may be separated from each terminal sound by the system designer. It is preferable to arrange it as shown in FIG. 33 so that it can be confused with the vowel input when it is overpassed.

As shown in FIG. 33 (VI), when the punctuation sign 'J' and the 'F' sign are arranged perpendicularly to each other, the movement of the finger for selecting 'ㅉ' Effect.

[Example 13]

In the thirteenth embodiment, consonant letters and extended key functions are assigned to each of the divided areas, and when the respective extended keys are selected, not only the vowel but also the consonants and muffles of the consonants allocated to the divided areas are also allocated to the extended area, It is characterized by a point that allows you to choose between mute or tremulous and vowel.

As shown in FIG. 34 (I), this configuration is applicable when the virtual keyboard of the touch-type input method has a sufficient space and there are left and right spaces of 12 key areas in which consonants are arranged.

Referring to Fig. 34, the virtual keyboard keyboard before the finger touches is shown in Fig. 34 (I), in which only consonants are arranged in ten keys. When the 'A' key region is touched in this state, another vowel arrangement according to the ninth configuration of the present invention is displayed around the 'A' key region (FIG. 34 (II)), The desired vowel input is performed by the operation, so that the consonant and vowel are simultaneously input by one touch.

(Fig. 34 (III)) or the 'ㄲ' region (Fig. 34 (IV)) in the state where the user tries to input 'ka' or ' ) And performing the drag operation for the vowel input, the input of the syllable combining 'ㅋ' or 'ㄲ' is completed instead of 'a'.

In FIG. 35, arrangements of vowels and consonants corresponding to 'c' and 'f' are displayed, and in FIG. 36, arrangements of vowels and consonants corresponding to 'g' and 'i' are displayed. Figures 37 and 38 show the extended arrangement of vowels and consonants for 'ㅇ' and 'ㅎ'. In the case of 'ㅇ', however, it should be extended unlike 'a, c, f, In the arrangement of the consonants shown in FIG. 33, there is not enough room for expanding the vowels in the arrangement of the consonants shown in FIG. 33. Therefore, in order to compensate for this, 'ㅎ' is designated as an extension consonant of 'ㅇ' If the user wishes to input the vowel at the same time or to simultaneously enter the vowel by constructing the expansion key '3701' in the 'hh' key itself, if the user touches the finger and moves to the expansion key '3701' You can also provide a way to have vowel arrays appear so you can enter them at the same time.

Therefore, simultaneous input of consonant + vowel according to vowel arrangement around each consonant key area shown in Figs. 34 to 38 effectively increases the advantage of the present invention, so that all consonants and vowels can be input by one touch .

[Example 14]

The embodiment 14 relates to a light and shattering key. In the above embodiment, the light and shatter keys convert the consonant input into consonant or phonetic sound after the consonant is input. This is because, in the present invention, This leads to a decrease in continuity.

Thus, in the fourteenth embodiment, when consonant and vowel are concurrently input, a consonant and a vowel are touched, and then the already inputted consonant is converted into a verb or a tremor.

For example, if you type 'a' and 'a' at the same time by dragging, 'a' is input and 'a' is touched, 'a' is converted to 'ka' , And the 'shake' key is touched, the 'k' is converted to 'k'.

Therefore, '- -> - -> ㄸ ->', - -> - -> ㅃ -> ', - -> ㅆ -> ㅅ, The conversion is performed even when the vowel is input.

Even the conversion of 'o' to 'heh' can be done in the same way. For example, after typing 'ah', touch 'Kyung, Dum' key and 'ah' will be converted to 'Ha'. Further, when the user touches the 'light / shake' key after 'H' is input, 'H' is converted back to 'H'.

The advantage of this configuration is that the operation for choosing the sound and sound of the consonants shown in FIGS. 33 to 38 is omitted, and merits of touching the 'light and shout' key are provided to maintain a consistent operation. That is, the user does not have to worry about the positions of 'k' and '더' if he / she only memorizes the position of 'a' as shown in FIG. 34. Further, ''',' It is not necessary to worry about the positions of 'ㅃ', 'ㅆ', ''',' ㅉ ', and' ㅎ '.

The input system of the present invention can be applied not only to Korean, but also to foreign language input systems such as English and Hindi.

First, in the case of English, in the case of English, there are many consonants immediately after consonants. Therefore, it may not be a great advantage to set a vowel input activation key as in Hangul.

Instead, when the word prediction input system is introduced, the extended key concept of the present invention can be a very convenient tool for inputting characters.

In a case where a plurality of characters are assigned to one division area, the word prediction input system predicts words that can be created by combining the letters assigned to the respective division areas selected by the user and displays them to the user, So that the word is input.

That is, there is a difference in that the input is done on a word-by-word basis rather than on a character-by-character basis.

In this case, the type of the word that can be formed by the combination of the characters allocated to the user-selected divided regions is allocated to the extended area generated when the user selects the extended key, The user can input a desired word by selecting a divided area to which the word is assigned.

Specific examples will be described with reference to the drawings.

[Example 15]

As shown in FIG. 39 (I), in a typical keypad mobile phone English mobile phone, a punctuation code is assigned to the key '1' (or 'QZ @' is assigned to the key '1' 26 alphabets are assigned to the keys '2' to '9'. In the configuration of this embodiment, symbols or characters are not assigned to one key among these number keys And serves as an extension key for selecting a prediction word.

For the convenience of users, as in Hangul, an example of specifying key 5 as an extension key for this purpose is described below. The alphabet is assigned from the key '1' to the key '9' excluding the key No. 5, and the key '5' (3801) is not assigned a character by itself (The number '5' can be specified.) It does not take charge of character input but instead simply acts as a function key for selecting 'prediction word'. The vowel input activation key in Korean is used for inputting a vowel while the extension key 3801 corresponding to the vowel input activation key in the predictive word input method can be used for 'prediction word selection' and input of a sentence code.

An example of applying the extension key to the virtual keyboard input system of the touch method is shown in FIG. 40 is a step of inputting 'am' in the input process of the sentence 'I am a boy.' In the touch screen type input device. When referring to 'T9' of Nuance, a well known word prediction system (www.t9 a ',' b ', and' c 'are designated in the virtual keyboard 3903 to input' am ' (In the drawings of FIGS. 40 to 61, when a virtual keyboard input system using a touch screen or a touch pad is displayed, a black circle is touched with a touch A line with an arrow means a drag operation in which a tail portion is first contacted and an arrow portion is finally separated. This is the same display method as that shown in Fig.

The predicted numbers and words are listed in the 'Predictive word list window' 3902 in the form of '16', 'an', 'am', 'co', and 'cm' Is provisionally input to the input window 3901 (Fig. 40 (II)). As shown in FIG. 40, the words entered in the input window are displayed as underlined lines, indicating that the word input in the input window is a 'provisional input word' and that the word prediction state is still maintained.

If the user touches the extended key with the next finger and then moves to the third key in the drag operation with no separation, 'am' is confirmed when the finger is separated (Fig. 40 (III)). In this state, the 'space' key is touched (see FIG. 40 (IV)).

The 'space' input method using the 'space' key shown in FIG. 40 (IV) can be further simplified by a single drag operation as shown in FIG. 41 (III) in the touch input method. That is, two touch operations are performed for selecting the 'predicted word' (FIG. 40 (III)) and 'space' input (FIG. 40 (IV)) in FIG. 40. In FIG. 41, Is completed.

42, the simple 'extended key' touch 4101 is input with the number '5' (FIG. 42 (I)), and FIG. 42 (II) and FIG. 42 The drag operation 4102 or 4103 starting from the 'extended key' shown in FIG. 3B or III is performed to select the 'predicted word' rather than the input of the letter or number ('5'). However, the drag operation 4102 starting from the 'extended key' shown in FIG. 42 (II) and ending with the remaining key completes the selection and input of the predicted word, Quot ;, the drag operation 4103 for returning to the " key "

In the drag operation 4104 shown in FIG. 42 (IV), when the touch start point is started from the remaining key other than the 'extended key', and the finger is dragged by the 'extended key' (symbol) is input.

Therefore, according to this configuration, when 'extended key' is used, 'predicted word' selection / input, 'space' input and ' Quot ;, "# ", and " * " keys) to provide an input system that is easy to complete in a one-thumb operation. It provides a more convenient way to input than a qwerty keyboard that requires two hands.

That is, if the extended key is used, it is not necessary to move the finger to the 'predicted word list window' 3902 in order to select and input the predicted word, and the user can easily select the desired word. The size of the 'predicted word list window' may become smaller because the desired word is not directly selected in the 'predicted word list window' 3902 with the finger. Thus, the 'predicted word list window' ) Can be eliminated.

In English, it is possible to further reduce the movement of the finger by designating 'space', which is most used in the process of inputting a sentence, as 'extended key'. To do this, a separate virtual keyboard mode for inputting the number '5' may be employed, or a number '5' may be assigned to a key other than the 'extended key' so that there is no problem in inputting the number '5'.

For example, in the key arrangement shown in FIG. 59 (I) or FIG. 59 (II), there is no need to designate the number '5' in the 'extended key'. In this case, Can be performed without regard to the number input function.

If 'extended key' is responsible for 'space' input function and 'word predictive state' is maintained, 'temporary input word' (3904 - shown under the input window) If you want to input a word (such as a temporary input), touch 'Extended Key' to set the 'Temporary Input Word' when you touch it, and enter 'space' at the same time Input of 'prediction word selection' and 'space' can be performed in a single operation.

When the 'word prediction state' is terminated, the 'extended key' simply performs the 'space' input function. If the 'extended key' in the 'word prediction' state is set not to perform any function with a simple touch-spacing operation that does not involve a drag operation, the 'extended key' can be a resting area . In addition, if the 'predictive word state' is not activated and the finger moves from 'extended key' to another key and is spaced apart, the function of inputting the key corresponding to the position where the finger is spaced apart The key selection for character input may be easily performed even if the key first touched by the finger is an 'extended key'. Further, if the 'shift' function is added to the above operation, the operation for inputting the 'shift' key for capitalization of the first letter of the word can be omitted. For example, if you touch 'extended key' without touching 'shift' key before touching 'ghi' key to enter 'I', move to 'ghi' 'G', 'H', 'I' are shown in uppercase letters of these characters, not 'g', 'h' and 'i' The input is ready.

As described above, it is a key point of the present invention that various functions can be performed by using one 'extended key', so that it is possible to provide a convenient input method rather than a qwerty keyboard with only 10 numeric keys.

That is, as shown in FIG. 42, in the case of the touch screen or the touch pad input system, various functions such as a simple touch / separation operation and a drag operation using 'extended key' are given different functions, .

In the touch screen or touchpad input method shown in FIG. 42, an operation using the 'extended key' may be performed by first touching the 'extended key' 4101 and touching the second 'extended key' An operation 4102 of selecting another key by a drag operation, an operation 4103 of touching a third 'extended key', selecting another key by a drag operation and then returning to an 'extended key' 4103, An operation 4105 of touching a key and selecting an 'extended key' as a drag operation; and finally, an operation 4105 of touching a key other than the 'extended key' and selecting another key after passing the 'extended key' .

As already described, the first operation 4101 is for inputting the number '5' or inputting 'space', and when the word prediction state is activated, 'temporary input word' and 'space' .

The second operation 4102 functions to input a 'prediction word', and the third operation 4103 functions to input 'space' simultaneously with 'prediction word input'. The fourth operation 4104 is responsible for entering the symbols designated for each key, and the fifth operation 4105 is responsible for modifying the symbol input.

FIG. 42 shows a result of a hand operation for operating an 'extended key' on a virtual keyboard, and a change in the color of the key and a change in the character assigned to each key.

FIG. 42 (I) shows a virtual keyboard with no change, which indicates that no key input is made before touching the 'extended key'.

That is, 'predictive word state' is inactive, so there is no 'word predictive list window' in the input window, and 'predictive word selection' is not performed even if a finger is moved to a neighbor key of 'extended key'.

However, if the key input is already made before the 'extended key' is touched and the 'word prediction state' is active (the 'prediction word list window' is displayed in the input window) As shown in Figs. 42 (II) and (III), it is possible to set each key area to change to yellow. This means that the 'word prediction state' has already been activated. In this state, when a finger is dragged to a key around the 'extended key', the user is notified that the 'predicted word' corresponding to the designated number is input It will be a role. The number displayed in each key corresponds to the list number in the Predictive word list window.

42 (IV) and (V), there is no change in the color of each key. However, the character shown in each key is different from the character shown in FIG. 42 (I) The user is informed that the 'symbol input state' has already been activated. In particular, in FIG. 42 (IV), when only the '1' key with the '!' (Exclamation point symbol) designated in yellow is displayed, the first touch position corresponds to the '1' key before the finger moves to the 'extended key' In FIG. 42 (V), the '3' key with the symbol '' '(double quotation mark) is indicated in yellow, indicating that the double quotation mark is entered when the finger is spaced.

The above describes an example of the operation of the finger operating the 'extended key' and the change on the virtual keyboard related to the operation. The 'extended key' operation shown in FIG. 42 (I) It is possible to change it.

FIG. 43 shows another example of the 'extended key' operating method shown in FIG. 42, the difference being that operations for inputting a symbol and inputting a predicted word have been changed. In other words, in FIG. 43, in order to input a symbol, 'extended key' is touched first and then a desired key is selected by a drag operation and then separated (4202). If 'word predicted state' is activated, 'predicted word' In operation 4203, a key corresponding to the number of the predicted word is first touched to select and then moved to the 'extended key' by the drag operation.

That is, since the operation for inputting the 'prediction word' does not start at the 'extended key' but ends at the 'extended key', the virtual keyboard does not change until the finger moves to the 'extended key' Extended key ', the color of each key changes to yellow as shown in FIG. 43 (IV), and the color of the first touched key turns blue to indicate the position of the first key touched.

Even if the drag operation of FIG. 43 (IV) does not need to be spaced apart from the 'extended key', there is no problem even if the same function is performed when the key is moved over a certain distance from the key of the first touched position.

FIG. 43 (V) shows an operation 4204 for inputting 'space' at the same time as selecting and inputting 'provisional input word', and it is necessary to return to the position of the first touch key to be separated. In fact, since the input of 'space' is used more than any character in English characters, the drag operation of FIG. 42 (II) and FIG. 43 (IV) is performed simultaneously with the input of the 'provisional input word' , The drag operation of FIG. 42 (III) and FIG. 43 (V) is set so that only the input of the 'provisional input word' is set so that the input of the 'space' .

42 (VI-1)), when the drag operation terminated at the 'extended key' and ends at the 'extended key' results in input of only the 'predicted word' without the input of the additional 'space' (VI-2). In this state, when the key designated by the sentence symbol to be input is touch-separated (FIG. 41 (VI) - 3) III < / RTI > and Fig. 42 (IV).

42 (VI-2)). The advantage of FIG. 42 (IV) is that the touch-spacing operation (FIG. 42 (VI) (VI-3), it is possible to select a symbol to be input easily. If the symbol is entered in a state of being ready for entering the symbol in FIG. 42 (VI) The user can escape from the symbol input process by touching the 'extension key' on the 'key keyboard'. To this end, the 'extended key' on the 'symbol keyboard' may be responsible for the input function of 'space', or it may only take the function of out of the symbol input process without any function. Will be.

The process shown in FIG. 42 (VI) can also be applied to the drag operation in FIG. 43 (V) to achieve a simple 'symbol input' process (FIG. 43 (VI)).

44 shows an example of a virtual keyboard in which only pure characters and symbols other than the input of numbers are assigned to respective keys. When such a keyboard is used, dragging operations 4301 and 4302 that pass the 'extended key' And a function of inputting one character out of the characters specified in FIG. That is, if the user touches the key '9' designated 'xwyz' and moves to the '4' key designated 'jkl' after passing the 'extended key' in the drag operation 4301, , 'y', and 'z', if the finger is separated from the '1' key, the first character 'x' , And 'y' if it is separated from '3' key.

That is, if the key corresponding to the last separating point is '1' key, the first character is input, if the key is '2', the second character is input, and when the key is '3' Even if four or more characters are set in each key, it is necessary to change the keys at the separated positions. Therefore, even when a character is input by the 'word prediction input method', a specific character or symbol This is possible.

Further, if the 'extended key' does not perform the 'space' input function, the number '5' can be input through the '5' key, so that the input of each number can also be performed by the drag operation shown in FIG.

For example, the character assigned to the key '1' contains a number '1', and the number of keys is 'a, b, c' (I) in the case of the key input of '1' in the 'word prediction input method', it is possible to input any one of the letters and numbers assigned to each key, The word is predicted by the 'Disambiquity Methodology' with respect to the four virtual keyboards 'a', 'b', 'c' and '1' 'a', 'b', 'c', and '1' need to be searched.

In the case where the 'Disambiquity Methodology' can not be applied as in the case of proper nouns, it is required to be converted into a mode (in the case of a mobile phone, a multi-tap method) in which each character constituting a word can be separately input, If the configuration of the input device is set so that each spelling is input by the dragging method of the virtual keyboard (for example, the conversion of the virtual keyboard mode such as the conversion to the multi-tap mode) Keyboard layout).

An example of assigning the function shown in FIG. 42 to the touch / drag operation using the 'extended key' is shown in FIG. This is the process of entering 'boy', the last word of the sentence 'I am a boy.' In case of 'boy', touch '1', '6', and '9' successively (Fig. 44 (I) The word corresponding to the predicted word arrangement number 'III' is selected and input into the drag operation starting from the 'extended key' (FIG. 45 (IV)) and the comma (.) Is selected according to the method shown in FIG. Quot; 8 " key to the " extension key "

As shown in FIG. 45 (III), there are nine words expected in the case of 'boy'. In order to select a desired word from the 'predicted word list window' 4401, which is enlarged, the 'predicted word list window' should be enlarged when the nine predicted words are listed on the screen, And even if the number of predicted words such as 'boy' is increased, the area for selecting each word becomes larger, which results in inconvenience that even the entire input window is covered.

In contrast, in FIG. 42, a key corresponding to an array number of a desired prediction word in the 'predicted word list window' is selected by a drag operation using the extended key '. In order to select and select the prediction words, a key input for predicting the word within the range of motion of one finger (thumb) and a selection of a 'prediction word' are made, and a desired word among the 'prediction word' is easily selected. Furthermore, since there is no need to touch the 'predicted word list window' area with a finger, there is no problem even if the size of the 'predicted word list window' is reduced to such a size as to be recognized.

Therefore, the advantage that the 'prediction word list window' hides the input window is also remarkably removed. This is an advantage brought about by the 'prediction word selection' method shown in FIG. 45 (IV).

This advantage is further developed in FIG. FIG. 46 shows prediction words arranged around the 'extended key' key to improve the intuitiveness of the 'predicted word list window' 4501. If the user does not check the underlined number of the 'predicted word list window' as in FIG. 45 (IV), the user can see the predicted word arrangement direction and drag the finger for selection The direction can be easily recognized.

46 (IV)), it is possible to determine whether the selection is correct or not by further changing the background color 4502 of the predicted word to be selected. In the case of inputting a symbol, if a finger is moved with the 'extended key', a 'symbol array display window' 4503 is displayed in the input window. If the background color 4504 of the key touched by the first finger is different from the surrounding key, It provides a way to check if the key corresponds to the desired symbol.

If the wrong selection is made, it can be easily modified before completion of input by the method shown in Figure 471 (II). 47 (II), when the 'extended key' is touched by a drag operation, a 'symbol array display window' is displayed in the input window and the background color of the key first touched by the finger is displayed differently from the remaining keys, If you make a wrong selection of a key other than the one you want to input, move your finger to the desired key without releasing your hand in this state, ) (Fig. 47 (III)). Therefore, it is possible to easily modify the key without having to perform an 'input cancellation' process. If the user does not want to input a symbol, (Fig. 47 (IV)), no input is made.

46 shows a case where a drag operation is required to input not only a 'predicted word' but also a symbol. FIG. 47 shows a case where a symbol key is displayed on the screen, .

47 (III) shows a case where the 'predicted word list' is displayed on the screen in a state where the first key, the sixth key and the ninth key are touched / spaced apart from each other. In this state (Fig. 47 (III)), if the user presses the 'extended key' and then performs the drag operation with the key 3 and the finger is separated (4602), 'boy' + 'space' (V-1), the 'extended key' is touched and then the drag operation is performed with the third key, and then the 'extended key' is again returned to allow only the 'boy' ) Is different from FIG. 46 in that the content of FIG. 42 (VI) is applied.

In the case of the drag operation returning to the 'extended key' (4603), 'key' is displayed on the screen simultaneously with the input of 'boy' (4604), the characters are not input but the symbols designated in the key areas are inputted.

In the case of the keypad system based on the twelve keys as shown in FIG. 39, the '5' key is referred to as " Extended key '. However, when the number of keys is increased or the arrangement is changed, it is possible to designate one or more extension keys. Also, it is possible to easily display the' predicted word list ' .

As shown in FIG. 59, in the case of a key arrangement of 3 * 4 (3 rows * 4 columns) (Figure 59 (I)) rather than 4 * 3 (4 rows * 3 columns) In the case of the key arrangement of 3 * 5 (3 rows * 5 columns) (Figure 59 (II)), two extension keys 5502 are arranged at the center left and right of the key arrangement, . 49 to 51, and the keypad 4703 shown in FIGS. 49 to 51 is a physical keyboard, not a virtual keyboard. The keypad 4703 shown in FIGS. Means a keypad.

As shown in FIG. 47, in order to input the word 'am', '1' and '6' keys having the letters 'a' and 'm' 5 'key and' 2 'key, which are' extended key ', in order to input' am ', which is a prediction word, 49 (III), the dotted arrow indicates that the drag operation corresponds to the touch method shown in FIG. Finally, press '5' key to finish typing 'space'.

However, unlike the touch method, in the keypad method, it is possible to distinguish whether the operation of pressing the '5' key corresponding to the 'extended key' is an operation for inputting the number '5' or a dictionary operation for inputting the expected word list number none. Accordingly, if only the character is designated by excluding the numeric designation in the key '5', the pressing operation of the key '5' takes charge of the function of inputting the predicted word list number when the word prediction state is activated , And the 'space' input function when the 'word prediction state' is not activated.

However, if the user presses the key for a long period of time, it is recognized as a pushing operation for inputting a number. In this case, the '5' key is used as an 'extended key' 5 ". < / RTI >

If the drag operation for inputting the symbol shown in FIG. 42 (IV) is applied to the keypad as it is, the user must press the designated key first and then the 'extended key' Since the 'word predictive state' is activated by pressing the key designated by the character, it can not be discriminated whether it is a pressing operation for inputting a symbol or a pressing operation for selecting a 'prediction word'. Therefore, in the keypad- The function corresponding to the drag operation in Fig. 42 (IV) which has been applied in the method of Fig. 42 (IV) can not be performed.

Therefore, as shown in FIGS. 49 to 51, a 'symbol selection function key' for specifying a symbol is set (in FIG. 49 to FIG. 51, the '#' key is designated as a 'symbol selection function key' Pressing the specified key and then pressing the 'extended key' will only work with the 'predictive word selection' function. Therefore, the symbol input is performed by pressing the designated key by pressing the symbol selecting function key.

Such a symbol input method is not a problem even if the 'extended key' is in charge of inputting 'space' when the 'word predicted state' is inactive, so the 'extended key' for inputting 'space' in FIG. Behavior reflects this.

If the keypad is operated with both hands by using both hands, it is also possible to designate it as a '*' key or a '#' key in the '0' key in FIG. 49. Instead, 'Space' input function is to activate 'temporary input word' and 'space' at the same time when 'word predictive state' is activated, and input 'temporary input word' This is more efficient than using 'extended keys' to do so.

The process of inputting the last words 'boy' and '.' Of 'I am a boy.' With this setting is shown in FIG. 50 (III)) corresponding to 'boy' by pressing keys '1', '6' and '9' in order to input 'boy' key 'key to select' boy 'and' 2 'key corresponding to the predicted word list number' II 'in order to finish typing' boy '.

Then press 'Symbol Select Function Key' to enter '.' And press '8' key to complete 'boy.' Input. Like the case of FIG. 49 (III), the dotted arrow in FIG. 50 (IV) is a reference for showing that it corresponds to the drag operation in the touch input method.

FIG. 51 is the same as FIG. 50, but shows a keypad arrangement type arranged around the 'extended key' rather than the 'predicted word list' arranged vertically. In the case of the keypad mobile phone, the size of the screen is not so large, and it is more difficult to select the word to be input in the 'predicted word list window'. The intuitive arrangement type This can be done easily.

In the word prediction input method, an extended key (a predicted word selection function key) is arranged at a position where finger movement can be minimized, and a predicted word is arranged around the key to easily select a desired word, And provides a way to increase the efficiency of the prediction method. Therefore, this configuration can arrange a list of words predicted from a dictionary database (Word Database) for a language other than English using a predictive word input method, around the extended key, and allow selection input from the list of words intuitively The principles are equally applicable.

FIG. 51 (VI) shows an example in which a configuration in which a 'predictive word' is selected and a 'sign language keyboard' is automatically activated is also applied to the keypad in the touch screen method shown in FIG. 42 (VI).

In the process shown in FIG. 42 (VI), the 'space' input function of the 'extended key' differs from the 'space' input function of the 'extended key' shown in FIG. 42 (I) This difference is also shown in the process of FIGS. 51 (I) to 51 (V) and FIG. 51 (VI). 42 (VI), the drag operation 4102 in which the finger is spaced apart from the key region in which the 'prediction word' is designated receives the 'space' input function at the same time and returns to the 'extended key' The drag operation 4103 which is spaced apart allows only the 'prediction word' to be input.

51 (I) to (V) in which the configuration of FIGS. 42 (I) to (V) is applied to the keypad system, the 'extended key' If '3' key corresponding to 'predicted word number' is pressed, 'predicted word' 'boy' is input.

51 (VI) in which the configuration of FIG. 42 (VI) is applied, pressing the '3' key corresponding to the 'predicted word number' after pressing the 'extended key' ) -①) 'Prediction word' and 'space' are input simultaneously. If the 'extension key' is pressed again in this state (FIG. 51 (VI) Predicted word ".

Thus, the same process and result as those applied to the touch screen method of FIG. 42 (VI) are obtained. Therefore, if you press the '3' key corresponding to the 'predicted word number' after pressing the 'extended key' ('5' key) while the word prediction state is active, If 'height' and 'space' are entered at the same time and 'extended key', which is 'symbol selection function key', is pressed in this state, the 'backspace' key function and 'sign board' Quot; space " inputted as a pushing operation (Fig. 51 (VI) -③) and concurrently pressing the pushing operation (the pushing operation corresponding to the dragging operation of Fig. 42 (VI) And the input cursor is positioned immediately after the already inputted 'predicted word' ('boy') (in fact, the drag process in the touch screen input method shown in FIG. 42 (VI) 51 (VI) -① and 49 (VI) -② which are the keypad method are not shown on the screen, 51 (VI-4)) is completed by pressing the key '8' designated with the symbol '.' (Period) to be input in this state. 51 (VI-5)

When the 'prediction word' is selected and the 'space' input is performed at the same time, there is generally no need to input the 'space' again by pressing the 'expansion key'. Does not occur. Therefore, if the 'space' input is frequent, the drag operation to the key region starting from the 'extended key' and the 'predicted word listing number' (I) to (V), the configuration of FIG. 51 (VI), which is applied to the keypad method, is more useful than the configuration of FIG. 42 (I) to (V).

Furthermore, if the 'word prediction state' is activated, if 'expansion key' is pressed twice consecutively to input 'temporary input word' and 'space' simultaneously, a separate 'space' key ('0 Quot; 'key), thereby providing a method of moving the finger within the keys 1 to 9.

[Example 16]

In Embodiment 16, the concept of the vowel input activation key is applied to the word prediction input system. In the embodiment 15 described above, a 'predicted word list' is displayed on a virtual keyboard that a user directly touches, The method comprising the steps of:

Generally, in the case of the word prediction input method, the user feels inconvenience in using the keyboard (keypad) and the input window while checking the prediction word and checking the key input. However, if the 'predicted word list' is displayed on the key of the virtual keyboard directly touching the finger (as in the touch screen method) as shown in FIG. 53, the input window for inputting words and the virtual You do not need to look at the keyboard alternately. Fig. 52 shows the same process of applying this configuration to Fig.

53 and 54 show an example of inputting by the word prediction method according to this configuration. FIG. 53 (I) shows a situation in which the first key 'c' of 'coordination' is touched by touching the key '1' in the process of inputting the English word 'coordination'. The contents of the 'predicted word list window' 5101 are displayed on the virtual keyboard as well as the input window. The 'predicted word list window' and the red colored key area on the virtual keyboard represent a 1: 1 correspondence relationship of 'extended key'. The 'prediction word' shown on the virtual keyboard is displayed in red to distinguish it from the blue characters assigned to each key. This is because the 'extended key' is displayed in red and it is reminded that the 'extended key' must be touched or the 'extended key' must be passed in order to input the 'predicted word'.

In these 'predictive word lists', words can be listed in alphabetical order, or they can be listed in order of most frequently used according to the frequency of use. However, if possible, the 'temporary input word' should be a position where the finger is easily accessible from the 'predicted word list window'. For example, '2', '4', '6', and '6' are located in the diagonal direction from the 'extended key' rather than the positions in the diagonal direction such as '1', '3', '7' It is preferable to arrange the 'temporary input word' in the latter position, and it is disposed in the key position '2' in FIG.

The virtual keyboard of FIG. 53 does not show the number assigned to each key, which is omitted on the assumption that users already know the position of the numbers. If necessary, a number may be displayed on the virtual keyboard as shown in FIG.

The reason for omitting the numeric display in the virtual keyboard is that, when the 'predicted word' is displayed in each key according to the purpose of the configuration, each key is displayed up to the number and character designated in the key and 'predicted word' 'Because it is difficult to recognize the number is not displayed for convenience.

The virtual keyboard shown in FIG. 53 is configured so that the 'extended key' is also set to perform the input function of 'space'. The 'virtual key word' is also displayed on the 'extended key' This is because it helps to prevent an input error by reconfirming the 'temporary input word' (the underlined word in the input window in FIG. 51) inputted at the same time when the 'space' is inputted at a distance. There is no problem if you do not display 'Expansion Key' because 'Expected Word List Window' shows underlined words as 'Temporary Input Word'.

53 (V) shows a case where there are two 'predicted words' (the 'predicted word' corresponds to the case where the alphabetical order of the words that can be input by the key order inputted up to now is 'dark' These predicted words are arranged above and below the extended key. This means that even if these 'predicted words' are lengthened, they are assigned to adjacent keys when placed in adjacent keys as in 51 (I) to (IV) So as to prevent overlapping problems between the predicted words.

When the first seven characters ('coordin') of the word 'coordination' to be inputted last are inputted (FIG. 54 (II)), since there is only one 'prediction word' Is the ending type. If the whole words are listed, they are separated from each other, so that only the ending variants are listed so that the words arranged in the neighboring key are not overlapped with each other, This is because it is easier to retrieve only the end variant than to search.

For example, as shown in FIG. 54 (II), it is possible to list additional ending variants such as -al, -ate, -ates, -ation, and -ating. When these ending variants are selected )) 'Coordin' marked 'predicted word' and the words combined with these modified forms are input.

In FIG. 54, the key 5201 in which the 'predicted word' is arranged has a blue background color, which indicates that there is only one 'predicted word', and the words arranged in the remaining keys are 'predicted word' Of the ending.

Therefore, when the background color of the key in which the 'predicted word' is placed is changed to blue, the user can easily search only the mother part in the 'predicted word list window', which is added to the 'predicted word' This is to guide you to see.

For example, as shown in FIG. 54, if the 'predicted word' has a blue background, the additional key input means that only the words based on the 'predicted word' already shown in the 'predicted word list window' Touching the 'extension key' and moving the '-ation' 5202, which is one of the mother change types, to the designated key by the drag operation, the input of 'coordination' is completed.

In other words, in a state in which 'coordin' is provisionally input as a predicted word, five touch operations necessary to additionally input the remaining spell 'ation' can be omitted.

In the state shown in FIG. 54 (II), it is possible to input all the words of 'coordination' rather than to look at the change form of the mother, and to complete the input of 'coordination' by touch- . In this way, when the 'ending type' is used, the words including all the 'ending type' are displayed on the respective keys on the virtual keyboard, thereby preventing a situation in which the predicted words assigned to the neighboring keys are overlapped with each other, It brings the advantage.

FIG. 54 shows a method of displaying predicted words in each key region on a virtual keypad (keyboard) by displaying only the ending when a predicted word has a long length. If predicted words are displayed in each key region The predictive word is arranged only in the keys located in the left and right columns of the 'extended key' and not arranged in the key in the same column as the 'extended key', so that the predicted word leaves the key area, It is possible to prevent overlapping with the arranged prediction words.

[Example 17]

Embodiment 17 provides a method of assigning a character to an 'extended key' in embodiments 15 and 16 in which 'prediction key' is applied to 'word prediction input method' to facilitate selection of 'prediction word' .

The virtual keyboard shown in FIG. 55 shows a case where the character 'jkl' is also designated in the 'extended key'. In this case, when a character is assigned to the 'extended key', the 'extended key' can take on the 'space' input function in the touch-separated operation (FIG. 42 (I)) among the 'extended key' But only the functions according to the drag operation shown in Figs. 42 (II) to (V) are taken.

For example, the symbol input shown in FIG. 42 (IV) is performed without any problem even if the character 'jkl' is assigned to the 'extended key'. That is, in the touch-type input device capable of recognizing the drag operation, even if the existing keypad (or keyboard) keyboard shown in FIG. 39 (I) is directly used, it does not interfere with the word prediction input.

Therefore, an advantage of this configuration is that the 'predicted word' can be easily selected while using the existing keyboard as it is in a touch-based input device. Although the 'predictive word selection' method is new, since the keyboard is used as it is, it is easily adapted to the input method according to the configuration of the present invention by using a keyboard that is already familiar.

However, since the '5' key, which is the function of 'extended key', can not be responsible for 'space' input function, input of 'temporary input word' should also be done by dragging. Therefore, if a separate 'space' key 5303 is responsible for determining the 'provisional input word' and inputting the 'space', it is unnecessary to determine the 'provisional input word' by the drag operation and the simple touch- The input of the input word can be completed.

[Example 18]

Embodiment 18 is a method for solving the case where all the predicted words can not be listed in the 'predicted word list window' because the space for the 'predicted word list' is limited, Move Key 'and select' Move Key 'to display another' Predictive Word List Window '.

56 to 58 show such a configuration. In the case of the general English keyboard shown in FIG. 40 (I), in order to input 'boy', 'abc' key, 'mno' key and 'wxyz' In the case where nine predicted words are input to Amy, any, boy, box, bow, cow, cox, coy, and BMW, the predicted word list window shown in FIG. 56 (I) If the space for the word is only 8 except for the 'expansion key' among the 1 to 9 keys, all these predicted words can not be displayed.

As a method for supplementing this, a 'move key' 5401 is assigned to one key region of the 'predicted word list window' and displayed in the list window together with the seven predictive words, and 'move key' 5401 is selected (5403) The user can select and input a word to be input ('BMW' in FIG. 56) by showing the remaining 'predicted word list window'. The move key 5402 shown in FIG. 56 (III) is a backward move key that can move back to the previous 'predicted word list window'. If the number of predicted words in the predictive word list window shown in FIG. 56 (III) exceeds 7, the forward direction key 5401 should also be included.

The virtual keyboard shown in FIG. 56 shows a case where the character 'jkl' is assigned to the 'extended key', and the operation method thereof is according to the configuration of the seventeenth embodiment.

57 and 58 show the contents of the 'extended key' instead of the 'moving key 5401 and 5402 shown in FIG. 56 instead of the' moving key '.

If there is no conflict with other functions of the 'extended key', the operation of touching / separating the 'extended key' when the 'word prediction state' is in the activated state is responsible for the function of the 'move key'.

Figure 57 (I) shows a state in which 'abc', 'mno', and 'wxyz' keys are continuously touched / spaced apart and 'any' is output to the input window as a 'provisional input word' And the 'Predictive word list' window is displayed on the screen. In this state, if the 'extended key' is touched / separated (FIG. 57 (II)), a second 'predicted word list' (FIG. 57 (IV)), there is no 'predicted word', so that the first predicted word list is switched to the first predicted word list.

If you want to enter 'BMW', you can move the 'BMW' to the designated area with the drag operation (5406) as shown in FIG. 58 (III) More simply, if the activated state of the 'word predictive list' (the character is not shown in each key area but only the predictive word is shown) as in FIG. 57 (III) or FIG. 57 (V) Can be inputted by simply touching / separating the designated area.

For example, in the case of FIG. 58 (I), in order to select and input the 'predicted word', it is necessary to move and separate the 'predicted word' from the designated area by a drag operation. However, Quot; predicted word " is displayed for each of the key regions, it is possible to input the 'predicted word' by touching / separating each key region.

57, the 'predicted word list' window is not displayed in the input window. However, when the 'predicted word list' window is displayed only on the virtual keyboard as shown in FIG. 57, 'Can be compensated for. However, since there is a disadvantage that the area of the input window is reduced when the' predicted word list 'is displayed in the input window, the presence or absence of the' predicted word list 'window is set according to the user's preference do.

The advantage of this configuration is that when the number of words predicted in the same key input is more than 10 or more than 20 in the case of the character input using the word prediction character input method such as Chinese and Hindi, And it is advantageous in that the user can select the 'predicted word' without leaving the finger of the virtual keypad (virtual keypad) or the character key area of the physical keypad.

49 to FIG. 51, the present invention can be applied to a keypad input device, so that it is possible to solve the inconvenience of hardly selecting a desired word among 'predicted words' by using a move key. For example, in the case of English, if the user wants to input 'BMW' shown in FIG. 56 to FIG. 58, it is possible to solve the inconvenience of pressing the move key seven times in order to search for 'BMW' from 'any' As shown in FIG. 58 (I), the 'predicted word list' is displayed in the input window, thereby allowing the user to always check whether or not the key input is correctly performed.

[Example 19]

In the embodiment 19, the 'extended key' is used in a glide manner in which a word is inputted by one touch-drag operation (the first character constituting the word is touched, and then, In which the last character of the word is passed in order and the word is input by separating the finger in the designated key region).

FIG. 60 is an example showing that the function set in the drag operation using the 'extended key' shown in FIG. 42 and FIG. 43 is applied to the glide type character input method to facilitate selection and input of 'predicted word' 'And a period ('. ').

The unusual thing is that the 'extended key' is specified as a separate key in the space between the 'g' and 'h' keys, so that it is located at the center of the keyboard so that the 'extended key' can be easily used. 60 (I) shows a drag operation 5601 that passes through each word constituting "wrote" to input "write", which is the last word of a sentence in a virtual qwerty keyboard. Words, which are predicted in the trajectory, are 'write, word, weird, wire, wore, wired' etc. These 'prediction words' are arranged in two key regions around the 'extended key' ))

This is because the full qwerty keyboard shown in FIG. 60 is generally smaller than the virtual keyboard using 12 keys, and it is difficult to arrange the 'predicted word' in one key because each key is small in size. If the full qwerty keyboard is large enough to accommodate the 'predicted word', it is not necessary to place the 'predicted word' over two keys as in (II).

The finger trajectory shown in FIG. 60 (I) is close to the locus for inputting 'word' rather than 'wrote', and 'word' is selected as the 'provisional input word' 5603. In this state, the key region designated by the period ('.') Is touch-separated (5604), indicating that the input of 'wrote.' Is easy. This is an example of applying the setting for facilitating the input of the 'prediction word' and the input of the symbol by using the setting of FIG. 42 (VI), that is, the 'extended key' It shows zooming by making it easier to input characters.

However, the 'sign board' shown in FIG. 60 (II) is used for a one-time input (meaning that after inputting a symbol, it automatically switches to the keyboard of the qwerty keyboard for inputting characters as shown in FIG. 60 It is also possible to apply a method of setting a separate keyboard switching key for fixing the 'symbol keyboard' in case that a symbol or a number must be continuously input. However, the drag operation 5602 shown in FIG. 60 (II) is an example for showing a function that can be activated to the screen naturally without touching a separate key by using the 'extended key' It does not mean that only the 'one-time' keyboard function can be applied.

The drag operation 5602 for selecting a predictive word is similar to the drag operation of inputting a vowel by using the vowel input activation key of Hangul, in which the two keys having different background colors are combined Or may be a movement of a finger over the area or even a direction toward the key area so that the direction of the drag operation coincides with these directions and the function is realized when the drag operation moves over a certain distance You may. This point can also be applied to the drag operation shown in Figs. 42 and 43. Fig.

[Example 20]

The twentieth embodiment applies a method of simultaneously inputting two keys in the word prediction character input method.

For example, in order to input the word 'boy' in FIG. 55, the '1' key designated 'b' is not touch-separated from the '6' key designated 'o' Touching the key area '1' and moving to the key area '6' will separate the touch start point and the designated characters at the separation point.

If the character designated by the key of the touch start point and the character designated at the spacing point are input at the same time, the input of 'boy' shown in FIG. 53 can also be completed by two touch operations. Two touch operations (two operations requiring touch-separation of the '1' key and the '6' key) are completed by one touch-drag operation.

If the function of the drag operation is appropriately set to each of the drag operations shown in FIG. 42 or 43 so that a conflict with a function given to the drag operation using the 'extended key' shown in FIGS. 42 and 43 does not occur The number of touches can be reduced to half. Furthermore, when the word prediction input method of the glide method shown in FIG. 60 is applied to the keyboard of the numeric key center of 4 * 3 (4 rows * 3 columns) arrangement shown in FIG. 39 (I) In this case, compared to the full qwerty keyboard shown in Fig. 60, the movement width of the finger is reduced, so that one finger (mainly the thumb The fingertip movement of the finger can be used only by the glide-based word prediction input method.

[Example 21]

When the word predictive state is in the inactive state, the drag operation using the extended key takes charge of the movement function of the cursor on the screen.

If there is no conflict with the function given to the drag operation using the 'extended key' shown in FIG. 42 or 43, if the cursor movement control function is given to the drag operation shown in FIGS. 61 (II) and 61 It is convenient to move the cursor to a desired position on the virtual keyboard while holding the finger fixed on the virtual keyboard. This is usually a keyboard, which brings the convenience of a pointing stick within the keyboard to eliminate the inconvenience of taking the mouse off the keyboard to manipulate the mouse to move the cursor.

61 is a process of using an 'extended key' to delete the word 'correction' shown in the fourth line of the input window 5701 in the touch screen input method. The virtual keyboard 5702 does not operate the 'prediction word' selecting function according to the touch of the 'extended key' because the 'word prediction state' is in the inactive state. Instead, when the 'extended key' ) Appears on the screen.

If you simply touch 'Extend Key' - you will enter 'space' or the function set for this action will work. However, in this configuration, when the user touches the 'extended key' and moves upward, downward, leftward, or rightward to cause movement of the cursor (pointer), and when the key is separated from the key labeled 'set for drag' Is maintained in the activated state on the screen, a drag operation that enables a user to select a desired word as shown in FIG. 61 (IV) becomes possible.

The 'selection' key is the main purpose of selecting the desired character, word or sentence. Therefore, if the key is separated from this key, it is necessary to move the cursor to select the entire character, word, or sentence. It is preferable to keep it active. Then, if you want to simply copy the desired word, touch 'copy' key. If you want to delete it, touch 'copy / cut' key and move to 'extension key' The word 'correction' is removed and the 'cursor control keyboard' disappears from the display and the 'keyboard' appears. This is because the purpose of eliminating the word 'correction' may be to insert it at another position, or it may be to insert a different word at a place where 'correction' was placed, so that the 'cursor control board' disappears, This is what you see on the screen. If the word 'correction' is to be inserted at another position, the 'extended key' may be touched and the finger may be dragged to the left, right, and up arrow keys 5704, as shown in FIG. 61 (II) or FIG.

There are various ways to manipulate the up, down, left, and right move keys. One of them is that while the finger is placed on these move keys, the movement of the cursor continues in the directions indicated by these move keys. This is a way to stop the movement of the cursor. However, in FIG. 61, it is shown that a method of controlling the cursor movement using the 'extended key' is also possible. Therefore, the 'extended key' can set not only the selection of the predicted word but also various functions necessary for the character input. In the case of the multi-touch capable touch input method, as shown in FIG. 59 (III) Since there is no problem even if a finger touches two 'extended keys' at a time by disposing a separate 'extended key' 5504, the 'extended keys' located outside the letter input keyboard will have additional functions Or the same function as the 'extended key' 5503 in the character input keyboard can be allocated to make the character input more convenient.

[Example 22]

The input from the word prediction in English described above can also be applied to the Korean language. This embodiment applies the word prediction method to the Korean input method using the vowel input activation key 2501 shown in FIG.

The word prediction method is precisely a disambiguating method if it is well known as a character input method already named T9. If multiple keys are assigned to a key, you do not need to press them several times to enter them, and you can enter them with just one push.

For example, to enter the word 'mom' in English in a general multi-tap manner, you must press the 'mno' key five times in succession, as shown below. In order to distinguish between 'o' and 'm', it is necessary to press the move key (→), so a total of 7 pressing operations is required. On the other hand, the word prediction method requires only three presses, resulting in an input speed increase of substantially twice as much.

The word prediction method, which improves the speed of character input, can not be easily applied to the Korean character input method because the combination of the characters assigned to each key makes the probability of the word predicted low, Similarly, the input speed can not be improved.

Table 1 shows the number of words having the same key order when searching for the key sequences that can be used for the Hangul words of the present invention shown in FIG. 85 (I) and the conventional Samsung Cheonjin, LG Naragul, Pantech SKY-II, Is in the order of 1 to 10 in ascending order.

), 지(ㅡ), 인(l)'삼재로 실제 모음을 입력하고 자음의 경우에만 단어예측방식이 적용하여 산출된 것이다. 그럼에도 불구하고 정확하게 1개의 단어만 예측할 확률이 90%에 지나지 않는다. For reference, it is impossible to predict how vowels can be predicted,

), Ji (ㅡ), and. (L), and the word prediction method was applied only to consonants. Nevertheless, there is only a 90% chance of predicting exactly one word.

In this respect, the order of the prediction accuracy is the order of the present invention> SKY-II> Naragle> In case of applying the real word prediction method, the expected input speed increase is 12% in case of Tianjin, 15% in case of Naruto, and 29% in case of the present invention. This result suggests that the word prediction method is difficult to apply to the conventional input method in the case of Hangul in view of the result that the input speed must be increased by at least 30% to utilize the word prediction method. Thus, Hahnal describes a keyboard layout that can be applied to word prediction.

Accordingly, the present invention provides a method for improving user convenience when the word prediction method is applied to the present invention. 72 is a variation of the keyboard layout shown in Fig. 27 for such a configuration.

One of the characteristics of the keyboard shown in FIG. 72 is that no vowel is assigned to the " light " Therefore, even if the word prediction method operates, the general input method can be selected at any time.

For example, when the word predicting method is operated with the keyboard shown in FIG. 72, only 'A' key is required to input 'k'. However, if you press the 'A' key and then press the 'Kyung, Shim' key, the word prediction method will confirm that the consonant input is 'ㅋ' and no more disambiguity will exist in the consonant. The input mechanism will operate the same as in normal input.

Likewise, in the case of the vowel, if the user presses the 'vowel input activation key (the key to the left key)', the input character is determined as a vowel, so that the ambiguity of the vowel classification is removed, will be.

Accordingly, according to this configuration, when the input method composed of the keyboard of FIG. 72 is used, an input method in which a general input method and a word prediction method are mixed can be realized. This is the essence of this configuration.

The input system of the present invention is also applicable to the Hindi input method. In the case of Hindi, since consonants and vowels are combined to form letters as in Hangul, it is possible to introduce the concept of vowel input activation key applied to Korean characters in the above embodiment.

More detailed description will be given through concrete examples.

[Example 23]

62, a vowel input activation key is applied to a hindi input method using a touch screen. As shown in FIG. 62, a consonant and a vowel are arranged in eight keys among 15 keys, . ≪ / RTI >

의 경우는 4개의 문자가 지정되어 있다. In addition, the character code including candrabindu can be assigned to a key in which these consonants and vowels are not designated. These characters can be assigned to a single key and input through an extension function like consonants and vowels (VIII)), it may be assigned to a different key as shown in FIG. And may be input at the time of consonant input as shown in FIG. 63 (VIII), if the character codes are assigned to a separate key and input through the extended function, the combined vowel is followed by the consonant at the position in the state where the finger is touched during the consonant input Input is possible. 65, for example,

The combination vowel is expanded and arranged around the key (Fig. 65 (III)) when the desired vowel is selected (Fig. 65 (I)) and returned to the original key position In this state,

(Fig. 65 (III)) (Fig. 65 (IV)) after moving the finger to the designated position by the drag operation

Is input. In this case, however, it is possible to have five rows of keyboards so that a combined vowel can be expanded and arranged. 62 (I) shows the main screen of the Hindi virtual keyboard, wherein the vowel input activation key 5801 is a key for all the vowels designated as the '

, And in the case of the remaining consonants, five characters including a representative character represented by a red character are assigned to each key, the characters belonging to each key are as follows,

, Four characters are designated.

The method of inputting the consonants using the virtual keyboard is as follows. 63, when characters corresponding to respective representative characters are touched on the virtual keyboard main screen, the characters assigned to the respective groups are displayed around the representative character keys as shown in FIG. 63. In the virtual keyboard main screen (FIG. 62 In the case of the representative character key located in the column, the consonants belonging to the group are arranged in the clockwise order. In the case of the representative character key located in the center column, the consonant characters are allocated from the top to the bottom with symmetrical shapes, In the case of counterclockwise, it is assigned from top to bottom.

If the size of the screen is such that the configuration of the virtual keyboard is not three columns but five columns, the representative characters assigned to the left and right columns of the virtual keyboard shown in FIG. They can be arranged symmetrically. One specific point shown in FIG. 63 is that characters belonging to each group are allocated around the representative character key by touching each representative character key, but no character is assigned to the representative character key position. Accordingly, in order to input a representative character representative of each key, a representative character key is touched on the virtual keyboard main screen, and when the characters belonging to each group are extended, the representative character is changed from the original position to the upper Because you are moved by one space, you must move your fingers up one space to select representative characters, and then separate your fingers. For example, one of the

Is input from the virtual keyboard main screen shown in Fig. 62 (I)

Touches a key 5803 represented by "

60A (I)) in which five characters belonging to this group are arranged in an enlarged arrangement

(Fig. 60 (II)) after the finger is moved to the position of the finger

Is input. The reason for not specifying any character in the position of the representative character key is that in the case of the Hindi consonant, it is possible to provide a method of easily inputting the symbols added to the consonant, and furthermore, . This will be described later in the vowel input method. In Hindi, the vowels are entered by a single key, unlike consonants. The Hindi vowels contain the same pronunciations in two forms. Dependent vowels are used in conjunction with consonants, It is called independent vowels that are not combined and used singly. Thus, a commonly used standalone collection (

) Are 11, and the combination vowel (

,

,

,

,

,

,

,

,

,

) Are arranged in the vicinity of the vowel input activation key, when the vowel input activation key is touched, the present configuration is provided. As shown in FIG. 62 (III), when the user presses the activation key of the vowel once, the independent vowel is arranged around the activation key of the vowel, and the vowel input activation key is touched twice 62 (IV), the combination type vowel is arranged around the vowel input activation key so that 21 vowels can be arranged in one key.

However, the combined vowel keyboard can be used to display the vowel input activation key by touching twice. In addition, when the consonant is input, the automatic vowel input is enabled and the combination vowel input is enabled. For this reason, you do not have to touch the vowel activation key twice. In other words, when the consonant is input, the vowel keyboard is always converted to the combined vowel keyboard, and the virtual keyboard is converted as shown in FIG. 62 (II). When the vowel input activation key is touched in this state, The vowel keyboard appears on the screen. Since the consonant vowel is always input after the consonant is input, if the vowel is input during the beginning of a sentence or the beginning of a new word in a sentence or during word input, if the vowel is converted to a standalone vowel keyboard, It is possible to reduce the labor required for the user to select the stand-alone type and the combined type. It is also an element of this configuration to automatically switch between a stand alone vowel keyboard and a combined vowel keyboard according to the sentence or word input situation. That is, in this configuration, after the space input for starting the sentence or the space for word spacing, the independent vowel input state is always maintained as shown in FIG. 62 (III). When the vowel input activation key of the virtual keyboard shown in Figs. 62 (I) and 62 (II) is touched, the independent vowel keyboard (Fig. 68 (I) II)), the activated vowel panel shows only half of the vowels to be input.

As shown in FIG. 69, when the respective short vowels are selected, the input of the corresponding long vowels is completed when the finger returns to the position of the vowel input activation key at the position of the short vowel and is separated from the position . The combination vowels are also input in the same way as the independent vowels, except that in the case of a combined vowel, there is no short vowel corresponding to the pronunciation [a]

As shown in FIG. 68 (II), when the combined vowel keyboard is activated, the remaining vowels appear on the screen together with the remaining short vowels.

(봄베이)처럼 자음 다음에 독립형 모음의 입력이 이루어져야 하는 경우가 있는데 자음의 입력이 이루어지면 자동으로 결합형 모음 자판으로 자동 변환이 이루어지도록 한 본 구성에 비추어 독립형 모음을 입력하기 위해서는 모음 입력활성화키를 터치하여 결합형 모음자판을 독립형 모음자판으로 전환시켜야 하는 불편함이 발생하게 된다. sometimes

(Bombay), it is necessary to input a standalone vowel next to a consonant. When the consonant input is made, the automatic conversion is automatically performed to the combined vowel keyboard. In view of this configuration, in order to input a standalone vowel, So that it is inconvenient to convert the combined vowel keyboard into a stand-alone vowel keyboard.

(봄베이)처럼

를 입력하기 위해서는 모음 입력활성화키를 통해 독립형 모음자판으로의 전환시켜서 입하여야 하지만, 도 67에 보여지는 바와 같이 자음입력 과정에서 결합형 모음자판을 독립형 모음자판으로의 변환을 이룰 수 있다. However, in the description of the consonant keyboard layout above, when the representative character key mentioned for a moment is touched, it is actually used for another purpose without assigning any character to the position of the representative character key. . In other words

Like Bombay

The vowel keyboard is converted into the combined vowel keyboard according to this configuration,

It is necessary to switch to a stand-alone vowel keyboard through the vowel input activation key. However, as shown in FIG. 67, the vowel keyboard can be converted into a stand-alone vowel keyboard during the consonant input process.

키가 배열되었던 위치(6201)로 되돌아와서(도 67(III)) 손가락을 이격하면 모음자판이 독립형 모음자판으로 변경되는 것이다. 만약 손가락이 도 67(II)의 상태에서 이격하면 위에서 설명한대로

이 입력됨과 동시에 모음자판이 결합형 모음자판으로 변경되므로

를 입력하기 위해서는 이미 결합형 모음자판(도 62(II))으로 변경된 모음 자판을 독립형 모음자판(도 62(III))으로 전환시키기 위해서 모음 입력활성화키를 두 번 터치하여야 하는 불편 함이 발생하게 되는 것이다. 더 나아가서 대표문자키가 터치 되었을 때 실제로 대표문자키의 위치에는 아무런 문자도 배정하지 않고 또 다른 용도로 사용되는데 이는 힌디어 자음의 경우 추가적인 기호(

- bindu, candrabindu, candra, nukta, halant)를 첨부하여 자음의 변화를 이루고 있는데 이들 자음 변화에 필요한 기호를 활성화시키는 기능을 담당하게 되는 것이다.

(Fig. 67 (II)) and then moves to the virtual keyboard initial screen (Fig. 62 (I))

When the finger is moved back to the position 6201 where the keys are arranged (Fig. 67 (III)), the vowel keyboard is changed to the independent vowel keyboard. If the finger is separated from the state of Figure 67 (II), as described above

The vowel keyboard is changed to the combined vowel keyboard

It is inconvenient to touch the vowel input activation key twice in order to switch the vowel key board already changed to the combined vowel key board (Fig. 62 (II)) to the independent vowel key board (Fig. 62 . Furthermore, when a representative character key is touched, it is used for another purpose without actually assigning any character to the position of the representative character key, which is an additional symbol in the case of the Hindi consonant

- bindu, candrabindu, candra, nukta, and halant) to make the changes of consonants.

The first letter of

As shown in Fig. 66,

In order to input the virtual keyboard,

Representative characters representing the group to which

Key is touched (Fig. 66 (I)),

(Fig. 66 (II)), the virtual keyboard initial screen (Fig. 62 (I)) is displayed

When the key is returned to the position 6201 (Fig. 66 (III)), four consonant auxiliary symbols (

- bindu, candrabindu, candra, nukta, halant), among which bindu

(Fig. 66 (IV)) after the finger is moved to the place where the finger is located

Is completed.

를 입력할 경우 먼저

를 입력하게 되고, 본 구성에 따라 모음 자판은 결합형 모음자판으로 자동으로 변환되어 도 71에 보이는 바와 같이 모음 입력활성화키를 터치하면(도 71(I))를 모음 입력활성화키 주변에 결합형 모음이 배열되고(도 71(II)) 이 상태에서 손가락으로 위로 이동하여 를 선택한 다음 다시 위로 이동하여

를 선택한 후 손가락을 이격한 다음 candrabindu가 지정된 키를 터치/이격하면(도 71(IV))

이 입력되는 것이다. As in the case of consonants, the method of inputting a letter symbol is the same in the case of vowels. For example, in Korean,

If you enter

71, the vowel keyboard is automatically converted into a combined vowel keyboard, and when the vowel input activation key is touched (Fig. 71 (I)) as shown in Fig. 71, 71 (II)). In this state, the user moves his / her finger upward to select it and then moves up again

(Fig. 71 (IV)), candrabindu touches / separates the designated key after separating the finger after selecting it,

Is input.

As shown in FIGS. 64 (V) and (VI), the consonant supplementary symbols may be input by using the key expansion function at the time of consonant input, or these symbols may be separately designated to the keys of the keyboard.

(halant) 처럼 candrabindu가 지정된 키의 바로 밑의 키에 지정할 수도 있고, 아니면 도 64(V)와 (VI)에 보이는 것처럼 자음키에 확장기능을 부여하여 자음 입력시에 동시에 입력되도록 할 수도 있으며 아예 문자부호를 모두 도 63(VIII)에 보이는 것처럼 candrabindu의 확장 영역에 지정할 수도 있다. 이는 터치식 입력 방식에서 드래그 방식이 가지는 장점을 활용하고자 하는 것이다. For example, the symbols used in the semi-consonant formation shown in Fig. 62 (I)

candrabindu may be assigned to a key directly below the designated key as in the case of a halant, or it may be input simultaneously with consonant input by assigning an extension function to the consonant key as shown in FIGS. 64 (V) and (VI) All of the character codes can be assigned to the extension area of candrabindu as shown in FIG. 63 (VIII). This is to utilize the advantage of the drag method in the touch input method.
