Description

Character input device {CHARACTER INPUT DEVICE}

The present invention relates to a character input apparatus, and in particular, by allowing the first direction input and the second direction input to be simultaneously or sequentially performed in one input unit, the number of characters that can be input in one operation in a minimum input space can be maximized. At the same time, the present invention relates to a character input device capable of quickly and accurately inputting one or more phonemes in one operation.

With the development of software, semiconductor technology and information processing technology, information devices are becoming smaller and smaller, and the amount and importance of character input in such information devices are increasing day by day.

However, many problems have been revealed in the input of various characters or commands in such information devices. For example, character input devices such as keyboards used in PCs / laptops have limitations in reducing their size, which makes it difficult to miniaturize such information devices. In addition, the input speed of PDAs and keypads used in mobile phones is slow. Incorrect input is often inconvenient.

In order to input letters / numbers / symbols at a higher speed in the above-described information devices such as PCs / laptops / PDAs / mobile phones, a so-called one-operation-one phoneme input in which one phoneme (character) is input in one input operation is performed. It should be possible to input such one operation and one phoneme, for example, a button or an input key for inputting 24 characters for Korean characters and 26 characters for alphabet characters need to be arranged in the information apparatus. If the target language is English, Japanese, or other foreign languages, more buttons or input keys need to be added than in Korean.

In addition, as the performance of the desktop PC is increasingly realized in the portable terminal, the portable terminal can perform input functions of various command keys (enter, space, shift key, F key, symbols, etc.) used in the keyboard keyboard as well as character input. The situation is reaching.

However, in the conventional input device used in various information devices, a character is arranged on each input key, and a method of tapping or pressing with a finger inputs a finger size in a personal portable information terminal such as a mobile phone having a narrow arrangement of input keys. It is difficult to arrange more than 24 keys.

This has been the reason why the keyboard has not been miniaturized until now, and in the case of a mobile phone, since only 12 buttons are inputted with a large number of characters, for example, more than 24 Hangul characters, it is inevitable to duplicate a plurality of characters on one button. As a result, repeated input phenomena frequently occurred twice and three times to input one character (phoneme). Therefore, the input was slowed and uncomfortable.

In order to solve such a problem, a character input method for inputting a combination of predetermined characters such as 'Cheonjiin' has been proposed, but the repeated input phenomenon has not been solved even by this method.

In addition, various types of character input devices have recently been introduced.

For example, a keyboard that can be rolled around and a virtual laser keyboard that detects the position of a finger and inputs it when a user performs an operation such as projecting an image of a keyboard keyboard on the floor and using a finger to input a keyboard thereon are released. will be.

However, this type of input device has a problem that it is always inconvenient to carry and carry, and can be input only in a state placed on the floor, there is a problem that it is not applicable to a personal portable information terminal that needs to be input by hand while moving.

As described above, for faster input, each character should be accurately inputted according to the user's intention while arranging a sufficient number of characters in a narrow arrangement space. However, this is almost impossible with a conventional input method or a conventional character input device. .

Accordingly, the applicant of the present application introduces a new type of input unit capable of moving input in a radial horizontal direction and / or pressing input in a radial vertical direction with respect to a reference position as an alternative to improve the problem of the conventional character input apparatus. It is characterized in that one or more phonemes are input during movement.

Accordingly, an object of the present invention is to provide a new input unit in which the first direction input and the second direction input are performed separately or in combination, thereby maximizing the number of characters that can be input in one operation in a minimum input space and providing one input. By inputting characters more than one phoneme quickly and accurately by operation, and maximize the number of keyboards that can be arranged in a predetermined space through a multi-stage input function and a beeple configuration,

In addition to the first direction input and the second direction input, a signal processing method for inputting only the characters detected at the first input and the last input during the circumferential movement input of the input unit, or the first direction input, the second direction input, and the center. By adding or combining various input methods such as a combination with a part or a sequence of inputs, three or more phonemes can be input by one continuous input operation, as well as an increase in the input capacity to increase the amount of characters that can be input. It is possible to easily input text editing commands such as enter, space, etc. required for general character input or input of numbers, symbols, special keys, etc. It is to provide a character input device that can be quickly and conveniently performed in a portable terminal.

Hereinafter, with reference to the accompanying drawings and the description of the claims, the configuration / operation of the character and data input device according to each embodiment of the present invention and the character and data input method will be described.

Claim 1 of the present invention is an input unit for the direction movement input and the direction pressing input, the sensing unit for generating a detection signal for the direction movement input and the direction pressing input of the input unit and the letter / number / corresponding to the detection signal of the sensing unit Disclosed is a character input apparatus of an embodiment including a control unit for extracting a symbol.

The input unit preferably maintains a constant distance close to all the sensing units, and moves in a plurality of radial directions from the center so that movement to each sensing unit is accurate and easy. (Claim 2)

In addition, the character input device may be input by moving the input unit in the circumferential direction, and a single input function is implemented in the controller. (Claims 3 and 4)

The input unit may be in the form of taking a movement of a normal (joy) stick or a pointing device driver capable of automatically moving back to the original position as described in claim 6 when moving in the direction movement input (claim 5).

Further, claims 7 and 8 of the present application, respectively, the character input device that the consonant is input by the position movement in the radial direction when the direction movement input of the input unit, and the consonant is moved by the position movement in the circumferential direction when the direction movement input of the input unit A character input device for inputting is disclosed, and the character input device is capable of input by moving a consonant input also in a radial direction and a circumference allowing movement in the circumferential direction of the input part since the input is possible by moving in a circumferential direction. The consonant is preferably arranged at a position corresponding to the radial direction in the movement path. (Claim 9) A vowel can be input on an input unit, and a character input device in which a vowel is input by a direction push input on the input unit is claimed. Claimed at 10.

Claims 11 to 19 and Figures 1 to 3 illustrate a character input method or a character arrangement method according to each embodiment of the present invention. More specifically with reference to the drawings, Figure 1 according to an embodiment of the present invention 2 is a model diagram illustrating a character input device, and FIG. 2 illustrates an example input unit employed in the character input device of FIG. 1, and FIG. 3 illustrates an input unit of another example employed in the character input device of FIG. 1. As can be seen from these figures, the user of the information apparatus employing the character input device of the present embodiment can input various letters, numbers and symbols by operating the input unit.

For example, as shown in FIGS. 1 and 2 modeling the contents of claim 11 and 12, the Korean mode or the English collection is easily input by switching the input mode of the input terminal 16 to the center of the upper surface of the input unit 10. Eight Korean vowels (ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ) and seven English vowels (A, I, E, O, U, W, Y) are installed around the installed button (12). Paired with each other and arranged in each of the eight directions, the remaining Hangul vowels (ㅡ, ㅣ) and the numbers 0 and 9 are arranged in the center of the input unit. In addition, 14 Hangul consonants and 1 to 8 numbers are arranged in 8 directions in the input region of the input terminal 16 having the elastic body 14 to return the input unit to its original position at the end of the input.

Here, the button 12 is preferably configured to have a sufficient recoil so that an input operation is performed only when the user of the information apparatus intentionally presses with a slight force. In the case of arranging 7 vowels of the English alphabet, 3 digits are 1 digit for vacancy-8 Hangul vowel digits and 2 digits for ㅡ, ㅣ digits compared to when the Korean vowels are arranged. You can arrange any alphabet in the English alphabet except seven vowels, or other commonly used functions such as enter, space, cancel, comma, etc.

Alternatively, as described in claim 13, the 12, 모 of the Korean vowels are input by the button 12 formed at the center of the input unit 10 and the pumping input, and ㅏ, ㅓ, ㅗ, TT of the remaining Korean vowels are input. Characters are arranged in four directions of, and by this operation, all 10 basic Korean characters are input.

For example, claim 14 and claim 15 of the input form of the Hangul basic vowel by the input unit of Fig. 3 is claimed, one of the forms of the Hangul vowel ㅏ, ㅓ, ㅗ, TT arranged in the four directions of the input unit Hangul vowels ㅑ, ㅕ, ㅛ, ㅠ are inputted by the direction input and pumping input (claim 14), and in another form, any one of the Hangul vowels ㅏ, ㅓ, ㅗ, TT arranged in four directions of the input unit. If you press the center button in succession together, Hangul vowel ㅑ, ㅕ, ㅛ, ㅠ will be input. (Claim 15) At this time, the remaining Hangul vowel ㅡ, ㅣ which is not described may be input by the button 12 and the pumping input shown in FIG.

Claims 16 to 19 are claimed in the input form of the English vowel using the input unit of Figure 3, in more detail ⑴ claim 16 in the alphabet vowel A, E, O, W arranged in the four directions of the input unit E, It is claimed that O, W are inputted into alphabetical vowels E → I, O → U, W → Y by direction input and pumping input, and according to claim 17, alphabet vowels A and I arranged in four directions in the input section. Of the U, Y, I, U, and Y are required to input I → E, U → 0, Y → W by direction input and pumping input, and according to claim 18, E, O, W is claimed to be input as E → I, O → U, W → Y by pressing a button in the center, followed by direction input of the input unit. In claim 19, I, U, and Y among the alphabet vowels are charged with a method of inputting I → E, U → O, Y → W by successive inputs while pressing a button at the center.

In addition, 19 letters of the English alphabet (consonants) except the 7 letters (A, I, E, O, U, W, and Y) classified as vowels among the 26 English alphabets are referred to in claim 20 and FIG. A pair of two pairs are connected to the radial path or the circumferential path allowing the direction input, and 16 can be arranged in eight directions and the other three (three characters) can be arranged in the input unit. In addition, in the case of Hangul, 14 basic consonants are arranged in 8 directions each so that there are two vacancies, so other letters / numbers / symbols frequently used can be arranged in this place (vacancy). In addition, the Korean consonants can be input by a combination input with the button when the basic consonants are input.

As described above, the character input device according to an embodiment of the present invention is characterized in that a consonant is input by the direction movement input of the input unit and a vowel is input by the input operation (direction push input) on the input unit. (Claim 21) That is, when the consonant input is input by moving the input unit in the corresponding direction (direction movement input), and when the vowel input to the direction pressing input in the corresponding direction on the input unit. Therefore, when inputting in the form of [consonant + vowel], the combination of the direction movement input in the radial direction and the direction pressing input can be completed in one operation. In addition, when inputting in the form of [consonant + vowel + consonant], the input can be completed by one operation of inputting the direction pressing simultaneously with the direction movement input in the radial direction and then the direction movement input in the circumferential direction.

In addition, when the consonant + consonant type is input, the consonant may be input by performing a radial movement input twice to a position where the consonants are arranged in letters. However, the movement is performed in the circumferential direction after the movement in the radial direction. It is also possible to connect.

Unlike Hangul, which begins with consonants in the alphabet, there are many words that precede vowels.

That is, when only the vowel is to be input, the vowel in the corresponding direction is pressed by pressing the vowel in the corresponding direction without moving the input unit horizontally while the input unit is positioned at the center of the input area where the input unit is moved.

When inputting in the form of [vowel + vowel], press direction direction twice in the direction that the corresponding vowel is arranged on the input unit.

In the case of [vowel + consonant] type input, the combination of the direction pressing input and the direction moving input in the radial direction can be completed in one operation.

Of course, when [consonant + vowel] input or [vowel + consonant] input, each input operation is not combined as described above, it is also possible to input separately by one operation. However, for faster input, it is more preferable to combine the direction movement input and the direction pressing input in one operation. However, in this case, the input of the consonant + vowel or the [vowel + consonant] type is determined according to which one of the direction moving input operation and the direction pressing input operation is performed earlier. That is, in the case of the [vowel + consonant] type input, the direction pressing input at the input unit is performed a little earlier than the direction moving input to complete one operation. This is a subtle difference but can be distinguished by mastery.

Input of the [vowel + consonant + vowel] type can be completed by the direction movement input in the radial direction immediately after the direction pressing input and then the direction pressing input again.

In the form of [vowel + consonant + vowel + consonant], the direction press input and the direction movement input in the radial direction are simultaneously input, and the direction press input is performed in succession, and the direction movement input in the circumferential direction is input, and the input part is located at the center position. This can be accomplished by successively returning the direction shift input in the radial direction.

In addition, when the user is familiar with his or her sense of distance and position of each input operation, the user can complete several characters in a sequence. Frequently used words will be familiar with the direction and order of each input operation and can be accomplished mechanically in just one action.

Here, each of the first data 312 may have a uniform distance from each other from the reference position 316, may be arranged with a different distance from each other, but provided to have a unique direction indicating position in the radial direction do. That is, when the direction movement input unit 320 moves in one radial direction from the reference position 316, only one first data 312 is selected from the plurality of first data 312, and two or more different firsts are selected. Data 312 cannot be selected at the same time.

Meanwhile, two or more different data may be disposed in each first data 312. In this case, the data arranged in each first data 312 may be classified into a plurality of character sets. For example, as shown in FIG. 32, firstly disposed data such as' B, B, C, ... 'are the first character set 312a, and' ㅈ,-, ..., .... 'Is classified as the second character set 312b, and' 1, 2, 3, ... 'is classified as the third character set 312c. Therefore, when any one character set is selected, only data included in the character set is input to the direction movement input of the direction movement input unit 320. Therefore, in order to input data included in another character set, the direction shift input should be performed after selecting the character set through the first switch key 303a or the single input unit 370. As a result, the Korean character may be converted into English characters and input, or information mixed with symbols or numbers may be input.

Preferably, each of the first data 312 may be disposed to form a uniform angle with each other on a circumference having the center of the reference position 316 and the separation distance as a radius. For example, as shown in FIG. 32, the circumference may be arranged in eight equal parts, or as shown in FIG. This is because the direction indication by the direction movement input unit 320 may be inaccurate when the data are arranged at mutually uneven angles, and the sense of appearance is deteriorated in appearance.

Here, each of the radially arranged data may be arranged over the entire circumference, or may be disposed only in a partial region of the circumference. In this case, since the data is not disposed below the direction movement input unit 320, that is, the position covered by the user's hand, the user's data input is easy.

Meanwhile, a plurality of different data may be overlapped with the second data 313 provided on the direction movement input unit 320. In this case, the base 311 may be overlapped with the second data 313. The apparatus may further include a second switch key 303b for switching from one of the plurality of data to another. Switching between such data may be useful when inputting consonants or vowels alone. Here, the conversion between the respective data may also be performed by a single input or a pumping input.

Here, when the first switching key 303a or the second switching key 303b is selected or by a single input or a pumping input, any one character set (for example, a Korean character set, an English character set, a vowel character set) Or a consonant character set, etc.), a light emitting unit (not shown) for displaying the selected character set may be further provided. As a result, the user can determine whether the desired character set can be input among the duplicately assigned character sets, thereby increasing user convenience and improving appearance.

The acoustic display unit 305 may be provided to inform the data input by the direction movement input, the direction pressing input, the single input, and the pumping input by sound. The sound display unit 305 may be provided as a speaker mounted on various information devices. As a result, the user does not need to alternately display the display 397 and the direction movement input unit 320 or the direction press input unit 350 to check whether the correct data has been input.

Move direction Input (320)

The direction movement input unit 320 is provided to be movable between the reference position 316 and the first data 312. Here, the movement method of the direction movement input unit 320 is not limited, for example, may be provided to be movable only in the radial direction around the reference position 316, both radial and circumferential movement It may be provided to enable.

In this case, the direction movement input unit 320 may be provided such that the direction movement input is made while moving from the reference position 316 toward the first data 312 according to the movement method, or from the first data 312. While moving to the position 316 may be provided so that the direction movement input is made, or may be provided so that the direction movement input by the movement in both directions.

The direction movement input unit 320 may be provided to be substantially horizontal with respect to the base 311. Here, the horizontal movement refers to the horizontal movement of the direction movement input unit 320 with respect to the plate surface direction of the base 311 and is not limited to the vertical movement with respect to the plate surface direction.

The direction movement input unit 320 may be provided in various shapes, but as shown in FIG. 31, the direction movement input unit 320 may be provided in a disc shape having a predetermined thickness. Because, when the direction movement input unit 320 is provided in a disc shape, the user's grip is easy, and since each data is arranged radially around the reference position, the radial movement and the circumferential direction of the direction movement input unit 320 This is because the movement of is easy. In addition, the direction movement input unit 320 may be provided in a polygonal plate shape as well.

As shown in (a) of FIG. 34, the direction movement support part 323 may be provided as balls 323a rotatable up, down, left, and right according to the movement of the direction movement input part 320, and as shown in FIG. 32B. Likewise, it may be provided as a cylindrical stick 323b.

When the direction movement support part 323 is provided as the ball 323a, since rolling friction is performed, friction between the direction movement input part 320 and the guide part 330 decreases, so that the movement of the direction movement input part 320 is smooth. . In this case, the ball 323a may include, for example, an acetal material having less surface friction and having wear resistance and durability.

On the other hand, when the direction moving support 323 is provided with a stick 323b, the direction moving support 323 may be provided to be rotatable about the center of the cylinder. In this case, when the direction movement input unit 320 moves in the circumferential direction, the friction between the direction movement input unit 320 and the guide unit 330 is reduced since the rolling friction is made like the ball 323a.

Referring to FIG. 45, the direction movement support part 323 may have a rod shape extending from the reference position 316 toward the direction movement input part 320 on the base 311.

In this case, the lower portion of the direction movement support part 323 is hinged to the base 311 to maintain the reference position 316 and to be movable in the radial or circumferential direction, and the upper portion of the direction movement support part 323 is the direction movement input part. Coupled to 320.

Here, the direction movement support part 323 may be provided to be accommodated and separated from the base 311, as shown in Figure 45a. In this case, when data input is not performed by the information apparatus, the direction moving support part 323 is accommodated inside the base 311 so as not to protrude to the outside, and when the data input is performed, it is separated out. Therefore, the volume of the information device itself due to the protrusion of the direction movement input unit 320 and the direction movement support unit 323 can be prevented from increasing, and the direction movement input unit 320 and the direction movement support unit 323 protrude outwards. If possible, it can reduce portable inconvenience and damage.

In the case where the numbers are arranged in the second character set 312b), as illustrated in FIG. 36, the first elastic member 315a provided between the direction movement input unit 320 and the base 311 and the first elastic member 315a are provided. The second elastic member 315b provided between the elastic member 315a and the base 311 may be divided and provided.

In this case, the direction movement input unit 320 moves in the radial direction until the first direction movement input detecting unit 381a detects the movement of the direction movement input unit 320, and inputs the first character set 312a. The second direction movement input detector 381b may be provided to move in the radial direction until the second character set 312b is input until the movement of the direction movement input unit 320 is detected. Therefore, character set switching is possible without a separate switching key or a single input unit 370.

In the data input device according to the first embodiment of the present invention, the direction movement input unit 320 moves radially from the reference position 316 provided on the base 311 toward the first data 312 disposed radially. Simultaneously with the movement input, the direction pressing input is made through the direction pressing input unit 350 provided on the direction moving input unit 320.

Referring to FIG. 49, first, a data input mode is entered using a function key provided in an information device (S11).

Next, the character set to be input is selected through the first switch key 303a or the single input unit 370 (S13). Here, the character set may include one or more of a Korean character set, an English character set, a numeric character set, or a symbol character set, and may further include a character set of another type.

Next, the direction movement input and the direction pressing input are performed through the direction movement input unit 320 and the direction pressing input unit 350 (S15). In this case, as described above, the single input or the pumping input may be performed in combination or selectively with the direction movement input or the direction pressing input.

That is, when 'a' is extracted by the direction movement input and 'ㅏ' is extracted by the direction pressing input, the controller 390 does not display this as 'a ㅏ' on the display 397. It can be displayed in combination. Here, the combination of the controller 390 may extract this as 'ga' even when 'b' is detected before 'a' within a predetermined time.

Thereafter, the controller 390 displays the extracted / combined data code on the display unit 97 (S23), and stores the extracted data code in the memory unit 395 (S27).

Here, when the character set is to be changed during the data input (S27), the character set is switched through the first switching key 303a, the second switching key 303b, the single input unit 370, or the pumping input to input the character set. Can be done.

In the second data 313 provided on the direction movement input unit 320, the user moves in a direction while pressing a direction pressing input key 357 to which 'ㅏ' is assigned. The entire input unit 320 is moved toward the first data 312 having 'a' disposed thereon. At this time, when the direction pressing input and the direction movement input are simultaneously sensed or simultaneously detected within a predetermined time interval, the controller 390 combines them in a 'ga' and displays them on the display unit 397.

Of course, instead of pressing the direction pressing input key 357, only the direction movement input unit 320 may be moved to input the letter 'a', on the contrary, the direction movement input unit 320 may not move the direction pressing input key 357 only. You can also enter 'ㅏ' by selecting.

If the user wants to input 'le', the direction movement input unit 320 may be moved toward 'r' while pressing the single input unit 370. Similarly, in order to input 'I', the entire direction movement input unit 320 may be pressed to perform a pumping input, and at the same time, move the direction movement input unit toward 'o'.

On the other hand, when the user wants to input a number, the user may switch from the Hangul character set to the number character set by using the first switch key 303a, and then move the direction movement input unit 320 to input the number.

Accordingly, in the data input device and the data input method according to the first embodiment of the present invention, two data inputs can be performed by one operation in inputting Korean, English, or other data, thereby shortening the data input time. Accurate data entry is possible. In addition, since it is not necessary to provide a button for each data for data input, it is possible to minimize the space for data input.

Second embodiment  (Figure 39 To  43)

The data input device according to the second embodiment of the present invention is characterized in that the linear guide 331 and the circular guide 336 is provided so that the direction movement input unit 320 is movable in the circumferential direction as well as the radial direction. do.

Prior to the description, a description overlapping with the above-described first embodiment will be avoided, and the description will be given based on the specific data input example. In particular, since the single input or the pumping input described in the first embodiment is commonly applied to other embodiments, the following description will be omitted.

First, a description is given of inputting 'tak' as an example. In the state where the direction pressing input key 357 corresponding to 'ㅏ' is selected, the direction movement input unit 320 is moved in the direction of (a) where '된' is arranged. Let's do it. The controller 390 combines the other based on the input signal detected up to this point. Finally, the direction movement input unit 320 is circumferentially moved along the circular guide 336 to the straight guide 331 in which 'a' is located, and then returns to the reference position 316 in the (b) direction. Accordingly, the controller 390 combines 'tak' and displays the same on the display 397.

Next, with reference to FIG. 43, the data input method in the case where two or more data are arrange | positioned in the 1st data 312 is demonstrated.

In the example of inputting '\', the first switch key 303a is used to switch to the second character set 312b while the initial first character set 312a is selected. In this case, the light emitter may indicate that the second character set 312b is selected.

Next, while holding the direction pressing input key 357 corresponding to 'ㅗ', the direction movement input unit 320 is moved toward 'Z'. At this time, the second data 313 is 'b' and 'c' are overlapped, but since the second character set 312b is selected, 'b' is not input even if the direction movement input unit 320 is moved.

Next, the direction movement input unit 320 is moved in the circumferential direction along the circular guide 336, and then stopped at the position where 'ㄹ' is located, and then the first character set 312a is used by using the first switch key 303a. After switching, when the direction movement input unit 320 is returned to the reference position 316, '촐' is input.

Here, the above-described switching between the first character set 312a and the second character set 312b may be performed by the single input unit 370 without using the first switching key 303a.

Therefore, in addition to the effects of the data input device according to the first embodiment, the data input device according to the second embodiment of the present invention may have two or more different data in the first data 312 or the second data 313. Since can be arranged in duplicate, it is possible to input various types of data while maintaining the minimum space required for data input.

Third embodiment (Figure 44)

The data input device according to the third embodiment of the present invention is characterized in that the direction movement input unit 320 is provided to perform the circumferential movement by the circular guide plate 337 after moving along the straight guide 331. .

Referring to FIG. 44, an input of “first” is described as an example.

First, while the direction movement input unit 320 is located at (a), the direction movement input unit 357 corresponding to 'ㅓ' is pressed and the direction movement input unit 320 is moved to the (b) position. At this time, the direction movement input unit 320 is moved along the linear guide 331. Next, when the direction movement input unit 320 is located at the (B) position and the direction movement input unit 320 is moved toward the (C) position, the circular guide plate 337 rotates and the direction movement input unit 320 is (C). ). Finally, when the direction movement input unit 320 returns from the (C) position to the reference position 316, 'first' is input.

Fourth embodiment (Figure 45 To  47)

As shown in FIG. 45, the data input device according to the fourth embodiment of the present invention is characterized in that the direction movement input is performed through the direction movement input unit 320 having a joystick shape.

Here, as shown in FIG. 45A, the direction movement support part 323 may be provided to be accommodated and separated in the base 311. Therefore, in a state where data input is required, the direction movement support unit 323 is protruded to perform direction movement input and direction pressing input. In a state where data input is unnecessary, the direction movement support unit 323 is accommodated in the base 311 and input. The volume of the device can be minimized.

Next, the direction movement input in the data input device according to the fourth embodiment of the present invention does not allow the direction movement input unit 320 to move horizontally from the reference position 316 toward the first data 312. It is characterized in that the inclination toward the input position toward each first data 312 from the initial position to maintain the horizontal state with respect to 311).

At this time, the direction pressing input is not limited, but may be made through a plurality of direction pressing input keys 357 spaced apart from each other at predetermined intervals on the outer circumferential surface of the direction movement input unit 320 as shown in FIG. 46.

50 is a schematic diagram illustrating a data input device according to another embodiment of the present invention.

Referring to FIG. 50, the data input device according to the present embodiment includes a data input unit 410 having a predetermined shape through which data is input by a user who displays input data; The data input unit 410 may include a direction movement input (movement in a solid arrow direction) in which data is selectively input by moving in a predetermined horizontal direction; By applying pressure (pressing) to a predetermined portion of the data input unit itself, a direction push input (movement in the direction of a dotted arrow) where data is selectively input is possible.

In this case, the direction movement input and the direction pressing input may be separately performed separately, or another input may be simultaneously performed while one input is being performed.

That is, in view of the data arranged, the direction pressing input can be input even during the direction movement input, and the direction pressing input can be set to be impossible during the direction pressing input, or vice versa or both can be set. Do.

Meanwhile, as illustrated in FIG. 51, the data input unit 410 may be divided into two or more stages of the direction movement input and the direction pressing input. This is to arrange a plurality of data in a small space and input the same. to be. For example, a plurality of pieces of data are arranged per direction in which the direction movement input is made, and the first data in one step movement and the second data in two steps movement. It is possible to arrange and select various characters in one direction according to the moving distance (moving pressure).

In this case, the multi-stage input may be classified according to the difference of the moving distance in the case of the direction movement input and the difference in the pressing distance or the pressing force in the case of the direction pressing input.

On the other hand, the direction movement input in Figures 50 and 51 is shown in the radial eight directions, in consideration of the size of the data and data input unit to be input, the size of the device to be mounted data input unit, the user's operation convenience in the radial two directions It is optionally used in the 12 to 12 way. Since the operability is extremely reduced in more than 13 directions, although not separately mentioned below, it is not impossible.

FIG. 52 is a diagram illustrating the direction pressing input in more detail. Referring to FIG. 52, the direction pressing input includes a five-way pressing including a central portion of the data input unit 410 and a radial four-direction pressing on the data input unit.

Of course, this can be changed in consideration of the data to be input and the size of the data input unit, and can be radially pressed in 2 to 12 directions, and it is also possible to select whether or not the center portion is pressed.

The data input unit 410 allows the user to move along an outline of a range allowed by the movement of the direction movement input, thereby preventing the movement of a long distance and providing the user with convenience of operation.

Although there are various methods, if the data input unit 410 is disposed on the concave circular base 420 as shown in FIG. 53, the outer edge of the base will be a range in which the data input unit can be moved. In consideration of this, the data input unit 410 is made larger than the base 420, and the concave-convex part and the like are provided at the lower part of the data input part. The range is determined.

The direction movement input of the data input unit 410 has a reference position (mainly in the center). Therefore, the data is input after a direction movement input or a direction pressing input in a predetermined direction and a separate input is not performed. It is preferable to return the input unit 410 to the reference position (initial position).

The direction movement input of the data input unit 410 is made in a direction movement detection unit substantially made of a sensor or the like. Such a direction movement detection unit 430 is on the data input unit 410 or as shown in FIG. 55. The data input unit may be disposed outside or on a movement path of the base 420 which is a stage on which the data input unit moves.

On the other hand, the direction movement detecting unit 430 may be arranged in various ways to be able to detect the moving pressure or the moving distance of two or more steps. Looking at the two direction movement detection unit 430 disposed on the left movement path of the base in Figure 55, each of them are spaced apart a certain distance in the movement direction, so that the direction movement input only to the inner direction movement detection unit If it is made, the one-step direction movement input is made, and if there is a further movement, when the movement to the outer direction movement detection unit is made, it can be set to the two-step direction movement input.

In addition, two direction movement sensing units are disposed on the right outer side of the base, and in the case where only the direction movement sensing unit operating by using a small pressure reacts with a different amount of pressure, the first stage direction When the movement input is made and the direction movement detection unit and the direction movement detection unit operated by the high pressure react simultaneously, it is possible to set that the two-step direction movement input is made.

This may be installed on the data input unit 410, or may be arranged in combination with each other.

In summary, the direction movement detecting unit 430 includes: a first direction movement detecting unit detecting a direction movement input of the data input unit 410; The second direction movement detection unit may be arranged to be driven by a movement pressure (distant movement) stronger than the first direction movement detection unit to sense a direction movement input of the data input unit. Of course, third, fourth,... Orientation movement detection unit is also possible, but the user's operability can be extremely degraded due to the subtle difference in the pressure.

The direction pressing input of the data input unit 410 is similar to the direction moving input, and the direction pressing detection is disposed on the upper surface of the data input unit or the lower surface of the data input unit or on the base 420 on which the data input unit is disposed. There is a section 440, and again two or more levels of input are possible, as shown in FIG.

Although the configuration is different from that of FIG. 56 in order to show the arrangement of the various direction press detection units 440, it will be appreciated that the present invention can be appropriately changed as an example.

First, the direction press detection unit 440 overlaps with the position directly touched by the user, such as the upper left side of the data input unit 410, and each of the first and second direction pressing inputs is changed by varying the reaction pressure. It may be made, it may be arranged to overlap the direction pressing detection unit 440 on the base 420. In addition, in the case of arranging a pillar (stick) in the center, the data input unit 410 is inclined due to pressure. Thus, the direction pressing detection unit may be disposed on the side of the pillar to allow a reaction to be made by tilting. It is also possible to use a combination of the above methods.

As such, the direction pressing detector 440 may include a first direction pressing detector for detecting a direction pressing input of the data input unit; Preferably, the second direction press detection unit is driven by a pressing pressure stronger than the first direction press detection unit to sense a direction press input of the data input unit. It is preferable.

In this case, when the direction push detector 440 is a button method, one of a membrane method, a rubber dome method, a pressure sensor, a contact sensor, and an optical sensor may be used.

On the other hand, the direction movement input of the data input unit 410 is preferably made of a sliding method, or a stick method of determining the direction by the overall tilt, such as a joystick.

Here, the direction movement detecting unit 430 and the direction pressing detecting unit 440 may be one of a touch sensor or an optical sensor using a pressure sensor or an electrical signal.

On the other hand, the data input unit 410 is an example in consideration of the operability of the data input, so that a two-way direction input and a single direction pressing input to generate only a single signal is made, or only one direction movement input and two signals It can be configured to generate a two-step direction pressing input to generate.

In this case, in particular, the entire data input unit 410 is preferably configured to enable a pumping input.

Here, the pumping input may be provided to enable more than two stages of input.

In addition, as described above, the data input unit 410 may arrange a double so as to be able to operate with each of the left hand and the right hand.

On the other hand, when the object input by the data input unit 410 is the ordered data, the direction movement input and the direction press input are made within a predetermined time, thereby inputting data having a first order and data having a second order. In the case where the data is input at the same time or the data having the second order is inputted first, the controller may be provided with a function of processing the data input having the first order first. If it is made at the same time or sequentially in a short time can be processed by receiving the consonant first prior to the vowel.

On the other hand, the direction movement input of the data input unit 410, as the direction increases the operation accuracy is lowered, in order to solve this, it is preferable to further include a direction movement guide for guiding the direction movement input. As such, when the direction movement guide unit is provided, the direction movement detection unit 430 that senses the direction movement input of the data input unit may be disposed on the direction movement guide unit.

Similarly, a direction pressing guide unit for guiding a direction pressing input of the data input unit 410 may be further provided. In this case, the direction pressing detecting unit 440 detecting the direction pressing input of the data input unit may press the direction. It may be disposed on the guide portion.

On the other hand, an elastic body for returning the data input unit to the first position after completion of data input is further installed around the data input unit 410 or the data input unit, wherein the elastic body may be made of silicon or rubber material.

In addition, the upper portion of the data input unit 410 may be formed concave or protruding to form a concave or convex in order to prevent slipping, the upper or the entire data input unit may be formed of a slip preventing material such as rubber. .

The data input unit 410 is recessed at the time of storage for slimming, and protrudes at the time of data input to enable data input, so that the data input unit 410 can be efficiently input even in a small space. The apparatus may further include a voice output unit configured to output the input data as voice when inputting data through the unit.

On the other hand, it is preferable to further include a data array display unit for visually displaying a data array menu that can be input to the data input unit 410, which is to display the arrangement of the data on a predetermined portion of the display as well as the arrangement described in the base, etc. For example, it is preferable to allow data input even when the user only sees the display. In this case, the data array display unit may further include a dimming unit therein so as to emit light for a visual effect or a night input. Similarly, the data input unit itself may further include a dimming unit therein for visual effect or night input.

Alternatively, a display unit disposed around the data input unit 410 and displaying data allocated to each radial direction may be used.

In this case, when a plurality of data sets are arranged in each radial direction, only the selected data set of the data sets may be displayed.

Data input in the data input device having such a configuration allows first data to be input when the direction movement input of the data input unit 410 is input, and second data is input when the direction input of the data input unit 410 is pressed. .

The first data and the second data are classified and arranged based on a data group (for example, consonants and vowels) that internally classify data to be input by a user. As described above, the first data and the second data correspond to a character set.

In order to increase the type of data to be input in such a data input method, two or more inputs are made. More specifically, in the case where the direction movement input of the data input unit is performed in two stages or the direction press input is performed in two stages, The third data and the fourth data are respectively inputted by the step input.

As another example, the first data and the third data different from the second data are arranged together with the first data, and the direction movement input is configured to enable two-stage movement. The second data may be input when the second stage movement input is combined with the fifth data when the first stage movement input or the two stage movement input and the direction pressing input are combined.

The above embodiment is summarized as follows.

First step movement input: first data,

Two-stage movement input: third data,

1st direction push input: 2nd data,

2-step push input: 4th data,

Combination of the direction movement input and the direction pressing input: fifth data

In this case, when the direction movement input and the direction pressing input are provided in multiple stages, the number of the fifth data varies depending on the combination between the multiple stage inputs. That is, as described above, when each direction input is provided in two stages, a combination of one-stage direction input and one-stage direction input, a combination of one-stage direction input and two-stage direction input, and two-stage direction movement A total of four fifth data can be input, such as a combination of an input and a one-step push input, and a combination of a two-step move input and a two-step push input.

Therefore, as shown in Fig. 51, even when each direction input has only four radial directions, the combination D5 between the respective direction inputs D1, D2, D3, D4 and each direction input for any one radial direction. 8 data inputs ( ₁ , D5 ₂ , D5 ₃ , D5 ₄ ) are available, so 32 data inputs are possible in total, and various data such as numbers, functions, mode switching etc. can be arranged in addition to various character array have.

On the other hand, in each of the above cases, a character is input when the direction movement input and the direction pressing input are performed in the same radial direction, and when they face different radial directions (for example, the direction movement input is true north direction, In the case of the direction pressing input, in the case of the positive direction), functions such as numbers, functions, and mode switching may be performed.

Here, the function may specifically include a function such as an enter, a spacer, a cancellation, or the like.

In addition, only one fifth data may be input by using a combination of the direction movement input and the direction pressing input, and two first or second data and two fifth data may be input.

That is, when the first stage direction movement input D1 and the first stage direction pressing input D2 are combined, only the fifth data D5 ₁ may be input, and D1 and D5 ₁ may be input at the same time.

Meanwhile, as illustrated in FIG. 55, in each radial direction due to the movement of the data input unit 410, a second data set to which a direction pressing input is performed may be provided differently.

That is, in the example shown in the drawing, when the data input unit 410 is moved in the S1 direction, the second data input set corresponding to the S1 direction, that is, the direction push input of P1 ₁ , P1 ₂ , P1 ₃ , P1 ₄ When the data input unit 410 is moved in the S2 direction, a second data input set corresponding to the S2 direction, that is, P2 ₁ , P2 ₂ , P2 ₃ , and P2 ₄ may be input.

Specifically, for example, in the case of a P1 set, a number is arranged, in the case of a P2 set, a symbol is arranged, and in the case of a P3 set, a computer function key (Function Key, F1, F2, etc.) is arranged. can do.

Therefore, in the above-described example, even in the case of having four radial directions, a total of 20 data inputs of the direction movement input (four) and the direction push input (16) are possible.

Of course, in the above example, it is also possible to implement a separate data input by the combination of the direction movement input and the direction pressing input.

Looking at the operation of the data input device of the configuration and data input method as described above, first, when the data input unit 410 is moved in a predetermined direction or a certain portion of the data input unit is pressed by the user, it detects this, the input of data The corresponding data is extracted from a pre-stored data set based on the signal detected in the data input process, and data input is completed by displaying the extracted data to the outside.

In the above, the part related to the character of the data input has been mainly examined, but as the development of the modern information society, the use of devices or programs requiring only a simple direction signal is increasing, and the data input device according to the present invention is It can be applied.

Referring to FIG. 57, the data input unit 410 may be divided into four portions as an 'X' to be used as a joy pad capable of inputting up, down, left, and right in four directions. For this purpose, the data input unit must first have a plate shape, and the data can be selectively selected by applying a pressure (pressing) to a direction movement input through which data is selectively input by moving in a predetermined horizontal direction and a predetermined portion of the data input unit itself. The direction pressing input may be input, but when using as a joy pad, the direction movement input may be limited and only the direction pressing input may be enabled.

Similarly, the device includes a stick-shaped data input unit 410 through which data is input by a user, and the data input unit includes a direction movement input for selectively inputting data by tilting in a predetermined horizontal direction, and the data input unit itself. By applying pressure (pressing) to a predetermined portion of the direction data input can be selectively input, but limiting the input direction input, and only the direction movement input to enable the use as a joystick .

A direction movement input for selectively inputting data by moving in a predetermined horizontal direction; After the data input unit 420 has a data input unit 420 capable of pressing the direction selectively input data by applying pressure (pressing) to a predetermined portion of the data input unit itself, and determines the movement of the mouse point by the direction movement input In addition, the click of the mouse button can be determined by the direction pressing input, so that the mouse can be used as a mouse.

At this time, in the direction push input, the data input unit may be divided into two ends so that the left part corresponds to the left mouse button and the right part corresponds to the right mouse button. The left portion may correspond to the left mouse button, the right portion corresponds to the right mouse button, and the upper and lower portions correspond to the mouse wheel.

On the other hand, as shown in the data input unit of the joystick of Figure 58 is provided with a data input unit of a predetermined shape in which data is input by the user and a base that is a stage to move the data input unit; The data input unit includes a direction movement input in which horizontal movement is performed by inclination of a stick-shaped elastic body installed through a reference position (generally center) of the base and data is selectively input; By applying pressure (pressing) to a predetermined portion of the plate disposed above the elastic body, the data input device may be formed to enable the direction pressing input where the data is selectively input.

At this time, the outer periphery of the base may be arranged to rotate to select the rotation of the data input mode by the rotation, which serves as a kind of function key described above. Of course, the rotating unit may be applied to a plate-shaped data input unit, and the specific function may include selecting at least one of Korean, English, Japanese, numbers, symbols, joysticks, mice, and joy pads.

Meanwhile, the character / data input device according to the present invention may be used as a remote control. For example, when one side of the data input device is provided with a connection portion (e.g., a known connection method using ultrasonic waves or infrared rays) for wireless connection to a TV, video, audio or computer, etc. By selecting a channel and pressing the direction input, it performs a function such as channel control or volume control.

In particular, in the case of a digital TV capable of bi-directional communication, it is very efficient because a text input for searching or storing a program can be performed in addition to the above-described general remote control function.

In addition, when watching a video or listening to music in the terminal itself, playback, rewinding, fast-forwarding, channel control, and volume control may be performed through a direction movement input (radial movement or circumferential movement) and a direction pressing input.

First direction input (M)

In the present specification, the first direction input M refers to a plurality of first direction indication positions M ₁ and M in which the input unit 10 is radially spaced about the reference position S from the reference position S. FIG. ₂ , ... are moved to any one of the first direction indicating position (M ₁ , M ₂ , ...) is to enter the characters.

FIG. 61 is a cross-sectional view of the combination of the input unit 10 and the base 110 according to the present invention shown in FIG.

Referring to the drawings, a reference position S (see FIG. 2) is provided at one side of the input radius 111 provided in the base 110, and a plurality of first direction indication positions are radially centered on the reference position S. M ₁ , M ₂ , ...) are spaced apart.

In addition, the base 110 is provided with a first sensing unit 61 that senses a movement of the input unit 10 corresponding to each of the first direction indicating positions M ₁ , M ₂ ,...

Therefore, when the input unit 10 moves from the reference position S toward the predetermined first direction indicating positions M ₁ , M ₂ ,..., The first sensing unit (. Based on the detection signal of 61, the controller 51 extracts and inputs, from the memory unit 55, the first character assigned to the first direction indication positions M ₁ , M ₂ ,...

The first detecting unit 61 may be provided in various kinds, for example, may be provided as a pressure sensor, an optical sensor or a touch sensor, and may be provided as a touch pad or a touch screen provided in the entire input radius 111. It may be provided, or may be provided in a track pointer method.

Here, the first direction indicating position (M ₁ , M ₂ , ...) may be provided in various numbers as necessary, as shown in Figure 61, eight (M ₁ ~ M ₈ ) may be provided, may be provided in four, may be provided in six.

The first direction input M may be performed in various ways. For example, the first direction input position is determined from a state in which the input unit 10 is located at the reference position S (see (a) of FIG. 63). Sliding toward (or horizontally moving, see FIG. 63 (b)) and performed.

Here, the sliding or horizontal movement is not limited to the exact horizontal to the bottom surface of the base 110, the first direction indicating position (M ₁ , M ₂ , ...) from the reference position (S) It includes all possible angles and directions towards.

In this case, when the input unit 10 performs the first direction input M, the input unit 10 may move in the radial direction about the reference position S, as shown in (c) of FIG. 63. It may also be performed while sliding in the circumferential direction about the reference position (S) within the radius (111).

FIG. 63 is for inputting 'height' in inputting Korean characters, wherein the input unit 10 has a first direction indication position M ₁ , M ₂ , ... to which 'b' is assigned from the reference position S. After sliding toward (see (b) of FIG. 63), it moves in the circumferential direction and inputs 'p' (see (c) of FIG. 63).

Here, the input of the second direction input P and the vowel '문자' will be described later.

In the above example, when the input unit 10 is moved in the circumferential direction, the input unit 10 may be detected by the plurality of first sensing units 61, in which case the control unit 51 finally detects the movement of the input unit 10. Only the detection signal of the first detection unit 61 may be effectively determined.

For example, when the input unit 10 returns to the reference position S, a reset signal is generated so that only the detection signal of the first sensing unit 61 generated immediately before the generation of the reset signal is valid. Can be judged.

Alternatively, when a signal of the same kind due to the input operation of the input unit 10 is turned off, only the last signal among the same kind of detection signals generated successively may be determined.

Alternatively, after the input unit 10 is moved in the circumferential direction to generate a plurality of detection signals belonging to the first direction input M, the center input C or the second is successively (ie, not returned to the reference position S). In the case of generating two kinds of sensing signals by performing the two-way input P, the first direction input M immediately before switching to the center input C or the second direction input P is determined as a valid signal. can do.

In the latter case, even if the input unit 10 does not return to the reference position S and generates a reset signal, there is an advantage that a valid signal can be determined from a plurality of detection signals.

Alternatively, various function commands may be input by circumferential movement of the input unit 10. For example, when the input unit 10 is circumferentially moved in the counterclockwise direction, a cancel command is performed. You can also make this input.

Here, as shown in FIG. 62, a support part 25 provided between the input part 10 and the base 110 to support the movement of the input part 10 may be further provided.

On the other hand, the first direction input (M), as shown in the left figure of Figure 76 (b), the entire input unit 10 including the support 25, the first direction indicating position (M ₁ , M ₂ ,. It may also be performed inclined towards any of the.

In this case, the input unit 10 may further include a support 25 for supporting the spaced apart from the base 110 by a predetermined height.

Here, the operation form of the input unit 10 for the first direction input (M) is not limited to the above-described form, the input unit 10 is made of a material that can be partially or entirely deformed by external pressure during the input operation It may be to detect the deformation direction of the input unit 10.

Alternatively, the first direction input M may be performed by providing a sensing unit (for example, a touch pad or a touch screen) that detects movement of a finger instead of providing the input unit 10.

Meanwhile, a guide part 40 provided on the base 110 to guide the movement of the input part 10 may be further provided.

When the input unit 10 moves, the guide unit 40 moves in the correct direction intended by the user, so that an accurate input is made without interference when the first direction input M is performed.

Guide portion 40 may be provided in various kinds, for example, a predetermined shape toward the first direction indicating position (M ₁ , M ₂ , ...) from the reference position (S) to the base 110 It may be provided with a linear guide formed of a groove.

Alternatively, as shown in FIG. 60, a disk-shaped groove corresponding to the input radius 111 is formed in the base 110 to limit the moving distance in the radial direction of the input unit 10 and at the same time the input unit 10. Can guide the movement in the circumferential direction.

Alternatively, as shown in FIG. 67, the groove may be provided with a concave groove corresponding to each of the first direction indication positions M ₁ , M ₂ ,...

In this case, the input unit 10 is provided in a shape corresponding to the guide unit 40, so as shown in (b) of FIG. 67, when the user performs the first direction input (M), the user input unit ( Even if 10) is moved in an incorrect direction, it may be moved along the guide portion 40 to a predetermined first direction indicating position M ₁ , M ₂ ,...

Here, the guide portion 40 may be provided with a variety of materials, for example, may be provided with an elastic material.

FIG. 69 is a detailed view of FIG. 67 (b). FIG.

The guide part 40 may be adjusted to move in the correct direction when the user moves the input part 10 in an incorrect direction, but if the input part does not proceed in the correct direction with the sensing part 61 as shown in FIG. The advancing direction is forcibly changed by the unit 40, and a large amount of force is required during the input operation, so that the user may feel uncomfortable.

In this case, if the guide unit 40 can be flowed according to the operation of the input unit, the user can operate the input unit more easily and simply. Referring to FIG. 68, the guide part 40 is fixed to the base 110, but an elastic body such as silicon is connected to one side thereof, so that the guide flows according to the operation of the input part 10 of the input part 10. The direction can be guided.

In more detail, as shown in FIG. 70, when the input unit 10 flows in the lateral direction of the guide unit 40, the guide unit 40 moves in the same direction in the input direction of the input unit, and the input unit 10 is the guide unit. Since the user pushes the 40 and proceeds in the same direction, the user can perform the input without any objection to the input operation. The moved guide portion 40 is automatically returned to its original state by the elastic force after the movement of the input portion is finished.

In the embodiment, when the guide part 40 flows, the sensing part 61 is also provided to be moved along the guide part 40.

Therefore, according to the above-described embodiment, even if the user does not exactly move the moving direction of the input unit 10 to the input direction, the movable guide unit 40 is moved according to the moving direction of the input unit 10. Since the sensing unit 61 is also moved along the guide unit 40 and sensed by the input unit 10, the user can complete the input with a soft feeling without rejection.

FIG. 72 is a flow guide part 40 of another form, which guides the circumferential movement of the input part 10. If the guide part 40 is fixed as shown in FIG. 71, when the input part 10 moves from the reference position S toward (a) direction and then proceeds along the circumference toward (b) direction, the input part 10 moves in the circumferential direction of the input part. If the traveling force of the cross section exceeds the resistivity of the direction angle, it can easily pass through the direction angle ((b)) of the direction to be inputted, causing a problem that the sensing unit of the next direction angle is detected. Can be. When the input unit reaches the desired direction angle, the user advances the input unit to the center to terminate the input, thereby reducing the driving force in the circumferential direction.

When the input unit 10 moves in the (a) direction and then moves along the circumference in the (b) direction, the direction angle acts as a shock absorber to reduce the traveling force in the circumferential direction of the input unit after some rotation along the input unit. Since the sensing unit moves along the guide, the sensing unit in the desired direction is stably grounded and maintained at the input unit.

Alternatively, when the support part 25 is located at the bottom of the input part 10, the support part instead of the guide part 40 is provided to be moved or rotated, so that the guide part 40 in the above-described embodiment is moved. The same effect may be produced.

On the other hand, the first direction input (M) may be provided to enable two or more stages multi-stage input according to the difference in the moving distance of the input unit 10 or the strength of the moving pressure.

That is, when the first direction input M is performed through the horizontal movement (or sliding) of the input unit 10 as shown in FIG. 61, each first direction indication position M ₁ from the reference position S is obtained. Two or more first sensing units 61 may be sequentially provided on a movement path of the input unit 10 facing M ₂ ,.

Alternatively, the contact portions 27a and 27b protruding from the input unit 10 or the elastic member 21 provided below the input unit 10 to be different in length toward the first sensing unit 61 may be provided. .

64 and 65 (c), the relatively long first contact portion 27a and the relatively short second contact portion 27b along the edge of the elastic member 21 provided below the input portion 10 are provided. The first sensing parts 61a and 61b may be provided on one side of the base 110 corresponding to the contact parts 27a and 27b.

Accordingly, when the input unit 10 is moved one step in a predetermined direction, the first contact part 27a contacts the first sensing part 61a first, and when the second step is performed, the first sensing part is moved up to the second contact part 27b. It contacts the part 61b.

Here, the first contact portion 27a and the second contact portion 27b may be provided to be sequentially crossed along the edge of the input portion 10 or the elastic member 21, as shown in (c) of FIG. .

The elastic member 21 includes a conductive material and is connected to the ground terminal 64 of the central processing unit (CPU) to transmit a ground signal to the contact portions 27a and 27b.

Alternatively, when performed by tilting the input unit 10, one or more optical sensors for detecting the tilt of the input unit 10 or the support unit 25 may be provided according to the tilt angle.

Here, the method of the first sensing unit 61 for detecting the two-stage input is not limited to the above-described example, and various modifications are possible.

An example of a signal processing method of the controller 51 at the time of multi-stage input will be described.

For example, in the case of performing the second stage input in the case of the first stage input M of the second stage, the first stage input is performed first, and the controller 51 performs the first direction input M of the first stage. After that, it is possible to determine whether the second stage input is performed by waiting for whether the second stage first direction input M is performed within a predetermined waiting time.

Preferably, the control unit 51 processes the first stage input without waiting for the waiting time once the first direction input M of the first stage is performed, but performs the first stage input when the second stage input is performed within the waiting time. Can be canceled and changed to 2-stage input. In this case, it is possible to prevent the input from being delayed during the waiting time.

Alternatively, whether the first stage input is released instead of whether the predetermined time has elapsed (for example, whether the first stage input M is performed and then returned to the reference position S, or the first stage input detection signal is released). (off), it is also possible to determine whether the first stage input is changed.

That is, the final input decision is made when the first stage input is released.

In this way, input processing is performed as soon as 1st stage input is performed, and input decision is made when releasing 1st stage input, but proceeds further without releasing 1st stage input regardless of waiting time, When it is executed, 1st stage input is canceled and it is changed to 2nd stage input.

In the above signal processing method, when the first stage input is processed due to an incorrect input when performing the second stage input, the second stage input is directly performed in the state of the first stage input processing without canceling the first stage input. Further, the first stage input may be changed to a two stage input, thereby enabling faster input processing.

As described above, when a predetermined input signal is detected, the input processing is performed immediately, but when the input is released, so that the final input decision is made, when the first direction input M or the second direction input P is wrong, When input is performed, input can be easily corrected to the desired input before the final input decision is made without having to delete the input contents and perform the input again.

Alternatively, when the first sensing unit 61 or the second sensing unit 63 is provided as a pressure sensor, it may be determined as the maximum pressure value generated within the waiting time.

Alternatively, the first sensing unit 61 may distinguish the first stage input and the second stage input based on the sensing time when the first sensing unit 61 detects the input unit 10.

For example, if the detection time is less than 0.5 seconds, it can be determined as a single stage input, and if it exceeds 0.5 seconds, it can be determined as a two stage input.

In the case of the pressure sensor, as described above, when the first stage input is performed, the input processing is performed immediately, and when the first stage input is released, the input is determined. If detected, the first stage input can be canceled and the second stage input can be determined.

Here, with respect to the signal processing of the controller 51 for the multi-stage input described above, in addition to the first direction input M, the second direction input P, the center input C, the direction combination input MP, PM, and the center Note that the same can be applied to combination input (CM, CP) and the like.

As described above, when the first direction input M is configured in multiple stages, the number of characters (or the number of characters that can be input through the first direction input M) increases accordingly.

Therefore, when a large number of characters are to be input through the first direction input M, the number of first direction indication positions M ₁ , M ₂ ,... Can be solved through the multi-stage input without any increase. The optimal input environment can be realized by appropriately adjusting the number of first direction indicating positions (M ₁ , M ₂ , ...) and multi-step input.

On the other hand, when two first direction indication positions M ₁ , M ₂ ,... Are overlapped with each other when the first direction input M is selected, for example, the input unit 10 has two first direction indications. When the movement of the input unit 10 is simultaneously detected by two first sensing units 61 by moving to the middle region of the positions M ₁ and M ₂ , interference between the input signals may occur.

In this case, the controller 51 may effectively determine only the first detection signal generated from the plurality of detection signals.

That is, the first input signal is effectively input processed, and the input signal is input before the first signal is released (for example, before performing the first direction input M and returning to the reference position S) or within a predetermined time. Other signals can be ignored.

Alternatively, all signal values that can be detected due to interference can be processed in a database. For example, when a detection signal is generated in one, two, or three first sensing units 61 at a predetermined position, a predetermined signal may be detected by making a database of input values for each case. When the database outputs the input value.

When the first detection unit 61 is provided as a pressure sensor, only the detection position showing the maximum pressure value can be effectively determined.

The input unit 10 may be provided in various shapes.

For example, as shown in FIG. 60, a disc shape may be provided, or a polygonal plate shape may be provided. As shown in FIG. 67, each of the first direction indication positions M ₁ , M ₂ , and FIG. It may be provided in a shape in which the side protrudes in the ...) direction.

In this case, a button-shaped protrusion 52a may be formed on the upper surface of the input unit 10 corresponding to each of the second direction indication positions P ₁ , P ₂ ,...

The input unit 10 may be made of various materials, for example, may be made of an elastic material.

Alternatively, both of the above may be provided.

The protrusion 53 is intended to facilitate input even when using the character input device 1 according to the present invention on a table or the ground, when using not only a thumb but also a finger such as an index finger or a middle finger. The protrusion 53 may be provided in various shapes. For example, as illustrated in FIG. 80 (d), the protrusion 53 may be provided in a ring shape or may be provided in a convex or concave shape.

In this case, the lower portion of the input unit 10 and the base 110 may further include a support 25 for supporting the input unit 10 to be tilted in any radial direction from an initial horizontal state.

Alternatively, as shown in FIG. 63, the second direction input P may include any one of the pressing parts 11 provided in the input unit 10 corresponding to each of the second direction indicating positions P ₁ , P ₂ ,... It may also be done by selecting one.

Here, the pressing unit 11 is any type that can independently select each of the second direction indicating position (P ₁ , P ₂ , ..) to the input unit 10 (except the tilt of the input unit 10 itself) It includes.

For example, the input unit 10 may be a push button or a push switch separately provided corresponding to each of the second direction indicating positions P ₁ , P ₂ , .., respectively. It may be a pressing position in which only the second sensing unit 63 is provided corresponding to the two-direction indicating positions P ₁ , P ₂ ,...

On the other hand, the second direction input (P) can also be circumferential input like the first direction input (M), the input function and signal processing associated with the circumferential input is the same as the first direction input (M).

Like the first direction input M, the second direction input P may be provided with a guide part 40.

When the input unit is provided as shown in FIG. 73, when the input unit is pressed, two or more press detection units 63 may be simultaneously detected. In order to prevent this, as shown in FIG. 74, the input unit 10 has an elastic member inserted into a lower end member, and a guide unit 40 is provided below the elastic member. The guide portion 40 is formed by forming a hard projection at a predetermined interval slightly smaller than the height of the pressing detection unit. When the user presses the input unit 10, only one push detecting unit responds to the operation of the input unit by the rigid guide unit 40, so that no interference occurs. 75 is a plan view of FIG. 74.

On the other hand, the second direction input (P) may be provided to enable two or more stages multi-stage input.

For example, the multi-stage input may be separately input according to the tilt point of the input unit 10 or the difference in the pressing intensity or the pressing distance of the pressing unit 11.

Referring to (e) of FIG. 62, when the second direction input P is provided in two stages, for example, a step is formed along the lower edge of the input unit 10 and the first stage is inclined. The lower second sensing unit 63a may be in contact with the base 110, and the second sensing unit 63b may be in contact with the base 110 by tilting the second stage.

In this case, the relatively long third contact portion 27c first contacts the second sensing portion 63a according to the degree of inclination of the input portion 10, and then the fourth contact portion 27d detects the second sensing portion when the second stage is input. It contacts the part 63b.

Here, the contact portions 27a and 27b may be provided as conductive members having elasticity.

Here, the method described above in the first direction input M may be similarly applied to the signal processing in the controller 51 when the second direction input P of the multi-stage is performed.

For example, in FIG. 66, the letter 'A' is input by contact with a predetermined second direction indicating position P ₂ , and the letter 'B' is tilted by the tilting to the second direction indicating position P2. It is input.

Therefore, the number of characters that can be allocated to the second direction indicating positions P ₁ , P ₂ , .. through the touch input can be increased, and the number of characters that can be assigned to the second direction input P in multiple stages can be increased. Character can be assigned.

In this case, by providing the contact portions 27c and 27d with different lengths, the third contact portion 27c is provided at the second direction input P at the first stage and the fourth direction is input at the second direction input P at the second stage. The contact part 27d can be made to contact.

On the other hand, the lower portion of the central input key 13, the fifth contact portion 27e in contact with the third sensing unit 65a at the first center input C, and the third sensing at the central input C at the second stage. The sixth contact portion 27f in contact with the portion 65b protrudes with different lengths.

In addition, at the outer circumference of the input unit 10, an elastic return member 58 is provided to return the input unit 10 to the reference position S after the first direction input M is performed.

64 and 65 show a character input device 1 according to the second embodiment of the present invention. Referring to the drawings, the first direction input M is performed while the input unit 10 slides from the reference position S toward the first direction indication positions M ₁ , M ₂ ,..., And the second direction. The input P is performed while the input unit 10 is inclined toward one of the second direction indicating positions P ₁ , P ₂ , .. from the horizontal position.

As shown in (c) of FIG. 65, the first direction input M includes contact portions 27a and 27b protruding along the edge of the input portion 10 or the elastic member 21 and the base 110 corresponding thereto. ) By the first sensing units 61a and 61b.

In this case, as described above, two or more stages of multistage input may be performed by varying the protruding lengths of the contact portions 27a and 27b.

On the other hand, for the second direction input (P), a support portion 25 for supporting the input unit 10 to be tiltable may be further provided. Of course, the support 25 may be provided in various kinds.

Alternatively, a sliding support 25 ′ supporting the sliding of the input unit 10 may be provided.

Meanwhile, referring to FIG. 65B, a return member 58 is provided below the input unit 10 to return the input unit 10 to its original position after the second direction input P is performed.

The return member 58 is provided on the elastic member 21 (or the input unit 10) and the PCB substrate 113 to be applied to both input operations of sliding and tilting the input unit 10.

Alternatively, the input unit 10 itself may be provided with an elastic material without providing the support 25, as well as an elastic body that is deformable between the input unit 10 and the base 110 may be tilted. This may be possible.

In this case, the second sensing units 63a and 63b may be contacted even when the input unit 10 performs the second direction input P in the predetermined direction while the input unit 10 performs the first direction input M in the predetermined direction. It has a predetermined shape and size (area) so as to be sensed by 27c and 27d.

76, (c) shows another embodiment of the present embodiment.

Referring to the drawings, an elastic member 40 is formed between the input unit 10 and the base 110 to form a pressing space, and sensing units 61, 63, 65 are provided below the elastic member 40. It may be.

A conductive member is interposed between the contact portions 27a and 27b and the elastic member 40, one end of the conductive member is connected to the ground terminal 64, and the other end thereof is connected to the contact portions 27a to 27f. The detection signal is transmitted to the controller 60 via 27a to 27f.

Thus, for example, when the first direction input M1 of one stage is performed, the outer contact portion 27a contacts the return member 58 to generate the first stage direction input signal. At this time, since the contact portions 27a and 27b contact the edges of the return member 58, the metal dome 24 maintains its original shape.

Next, when the first stage input M2 is performed in two stages, the metal dome 24 is deformed while the inner contact portion 27b is lowered to contact the first sensing unit 61b to generate two stage direction input signals. do.

In this process, since the metal dome 24 is deformed to give a feeling of click, the user can easily distinguish between the first stage input and the second stage input.

In the character input device 1 according to the third embodiment of the present invention, the first direction input M has the first direction input position M ₁ , M ₂ , ... Sliding toward) is performed, and the second direction input P is performed by tilting toward the second direction indicating positions P ₁ , P ₂ ,.

Here, 'tilt movement' means that the entire input unit 10 is inclined toward a predetermined direction (or at the same time as the support unit 25), as shown on the left side of FIG. 76 (b).

On the other hand, 'tilt' means that the input unit 10 is inclined with respect to the support unit 25, as shown on the right side of FIG.

Here, although not the aforementioned 'tilt movement', as shown in FIG. 66, the first direction input M is performed by sliding, and the second direction input P is also performed by tilting the input unit 10. May be

Alternatively, in addition to the first direction input M being performed by sliding and the second direction input P being performed by the tilt movement, the input unit 10 may be tilted in place.

In each of the above-described embodiments, the input unit 10 may be provided to protrude and accommodate in and out of the base 110.

Therefore, the volume can be minimized by accommodating the input unit 10 into the base 110, and an easy operation is possible when protruding the input unit 10.

FIG. 76B shows a character input device 1 according to the fourth embodiment of the present invention.

Referring to the drawings, the first direction input M is performed by 'tilt movement' of the input unit 10 (see left drawing), and the second direction input P is performed by tilting the input unit 10. (See right drawing).

The input part 10 is supported by the support part 25, and the support part 25 includes an elastic material, and the input part 10 is tilted to the first direction indicating positions M ₁ , M ₂ ,... Makes this possible.

Tilt movement of the input unit 10 is performed by the edge of the input unit 10 is in contact with the first sensing unit 61 provided in the base 110.

On the other hand, the second sensing unit 63 for sensing the second direction input (P) by the inclination of the input unit 10 is disposed on the PCB substrate 113 corresponding to the lower portion of the input unit 10.

In each of the above-described embodiments, the first direction input M or the second direction input P may have the same number of direction indicating positions or may have different number of direction indicating positions.

In addition, one or more of the first direction input M or the second direction input P may be provided to enable multi-stage input.

For example, the first direction input M may be provided as a first stage input, and the second direction input P may be provided as a two stage input. In this case, the consonant characters may be input by the second direction input P, and the vowel characters may be input by the first direction input P. In addition, consonants and vowels are input at the first stage, and consonants, direction indications, special symbols, function keys, or menu sets are respectively provided at the first and second direction inputs. Information, screen settings, Internet access, ringtone selection, message composition, etc.), and can also be operated with the mouse. If the mouse function is set in the second stage as described above, the input key can be used as a mouse by inputting or pressing the input key in the second stage without changing the mode.

This is because the number of consonants in the letters of the most of the countries compared to the vowels in terms of number and frequency of use, the second direction input (P) rather than the first direction input (M) can be relatively easy when multi-stage input Because.

As described above, the character input device 1 according to the present invention can input characters quickly and accurately by combining the first direction input M and the second direction input P having different input operations. .

This is because the consonants and vowels can be input separately according to each input operation in the input of almost all national characters in which consonants and vowels are repeatedly mixed and arranged.

Furthermore, since the first direction input M and the second direction input P are not bound between each input operation (that is, to perform one input operation necessarily another input operation, etc.) a plurality of inputs By performing the operations in succession, they can be performed as if they were a single input operation.

For example, referring to FIG. 94, an input example of the character input apparatus 1 according to the present invention will be described. When an alphabetic character 'CAR' is to be input, the second direction indicating position to which the consonant 'C' is assigned ( After tilting the input unit 10 (or selecting the pressing unit 11) toward P ₇ ), the input unit 10 is moved toward the first direction indicating position M ₁ to which the vowel 'A' is assigned. Next, the input unit 10 may be inclined again toward the second direction indicating position P ₂ to which the consonant 'R' is assigned.

Fig. 103 is a view for explaining another example of input of the character input device 1 according to the present invention. In the embodiment of FIG. 103, it is assumed that a consonant character is input by a first direction input and a vowel character is input by a second direction input. In FIG. 104, the user performs a direction pressing input toward a predetermined second direction indicating position (①) and moves toward the predetermined first direction indicating position M ₁ , followed by (②) a circumferential direction. Move to the one-way instruction position (M ₃ ) and return to the reference position (S).

 "A B C" is input by the above operation. The first direction input and the second direction input are performed at substantially the same time, and in this embodiment, the second direction input is performed first with a slight difference.

105, 106 Add description

FIG. 105 shows that after moving toward the first direction indicating position M ₁ , the input unit is inclined toward the second direction indicating position P ₆ , and then moved on the circumference to the first direction indicating position M ₃ . Return to the reference position (S). "BAC" is input by the above operation. In this embodiment, the first direction input is performed first with a slight difference than the second direction input. FIG. 106 shows the input unit moving to the first direction indicating position M ₁ , and then moving to the first direction indicating position M ₃ along the circumference, and toward the second direction indicating position P ₆ . In the operation of returning to the reference position S after tilting, "BCA" was input by the operation.

Here, the three operations described above may be performed in a connected operation with a slight difference, rather than each performed, so that a word composed of a plurality of letters may be input as a continuous operation.

Meanwhile, as illustrated in FIG. 116, the first direction input M may be performed while the input unit 10 is inclined toward any one of the first direction indication positions M ₁ , M ₂ ,... have.

Referring to FIG. 116 (a), the first direction input M is performed by 'tilting movement' of the input unit 10, and the second direction input P is performed by tilting the input unit 10. .

In this case, the input unit 10 may further include a support 25 for supporting the spaced apart from the base 110 by a predetermined height.

Accordingly, when performing the first direction input M, the input unit 10 is grasped with two or more fingers, and the input unit 10 is tilted to each of the first direction indicating positions M ₁ , M ₂ ,... (See M in Fig. 116 (a)), when performing the second direction input P, the input unit 10 is set to the predetermined second direction indicating positions P ₁ , P ₂ , .. Can be entered by tilting toward (see P in FIG. 116 (a)).

Here, when the first direction input M is performed by tilting the input unit 10 as shown in FIG. 116, the optical sensor for detecting the tilt of the input unit 10 or the support unit 25 is tilted according to the tilt angle. One or more may be provided.

116 (b) shows a character input device 1 according to another embodiment of the present invention.

Referring to the drawings, the first direction input M is performed while the input unit 10 slides from the reference position S toward the first direction indication positions M ₁ , M ₂ ,..., And the second direction. The input P is performed by tilting toward the second direction indicating positions P ₁ , P ₂ ,...

Here, 'tilt movement' means that the entire input unit 10 is inclined toward a predetermined direction (or at the same time as the support unit 25), and is moved in 'M' and (b) of FIG. 116 (a). 'P' corresponds to this.

On the other hand, 'tilt' means that the input unit 10 is inclined with respect to the support unit 25, and 'P' in FIG. 116 (a) and 'P' in (c) correspond to this.

Here, although not the aforementioned 'tilt movement', as shown in FIG. 116 (c), the first direction input (M) is performed by sliding, the second direction input (P) of the input unit 10 It may also be performed by tilting.

Alternatively, as shown in FIG. 6E, in FIG. 6C, the first direction input M is performed by sliding, and the second direction input P is performed by tilting movement. In addition, the input unit 10 may be tilted in place (see P ').

116 (c) shows a character input device 1 according to another embodiment of the present invention. Referring to the drawings, the first direction input M is performed while the input unit 10 slides from the reference position S toward the first direction indication positions M ₁ , M ₂ ,..., And the second direction. The input P is performed while the input unit 10 is inclined toward one of the second direction indicating positions P ₁ , P ₂ , .. from the horizontal position.

Here, the support 25 for supporting the input unit 10 to be tilted may be further provided. Of course, the support 25 may be provided in various kinds.

Alternatively, the input unit 10 itself may be provided with an elastic material without providing the support 25, as well as an elastic body that is deformable between the input unit 10 and the base 110 may be tilted. This may be possible.

Each of the above-described embodiments has described a basic form in which the first direction input M and the second direction input P are combined in the character input device 1 according to the present invention. As well as possible, modification of the shape, size, material, etc. of each component is possible without limitation.

Hereinafter, additional configurations and various modifications that may be included in the above-described basic form will be described in detail.

Each of the components to be described later may be applied alone, of course, two or more may be applied at the same time, in which case various combinations are possible.

Center input (C)

In the present specification, the central input C refers to a central input key 13 provided in the center of the input unit 10 separately from the first direction input M or the second direction input P, or the input unit 10. ) Is to be performed while lifting itself up and down.

For example, as shown in FIG. 61, the central input C includes a central input key 13 selectable at the center of the input unit 10 and a third sensing unit sensing selection of the central input key 13. 65 may be performed.

Alternatively, as shown in (d) of FIG. 62, the central input C is provided such that the entire input unit 10 is movable up and down with respect to the base 110, and the input unit 10 or the base 110 is moved. Any one of the above may detect the vertical movement of the input unit 10.

Here, only one of the above-described two types of central input C may be provided, but of course, may be provided at the same time.

On the other hand, the center input (C) is of course possible to input two or more stages according to the pressing distance or pressing strength of the center input key 13, or the lifting distance of the input unit 10 itself.

Meanwhile, a touch input for inputting another character allocated to the central input key 13 may be performed by sensing an approach or a contact with the central input key 13.

In this case, the central input key 13 is provided with a central touch sensing unit 61a for sensing the approach or contact of a finger.

Here, when the center touch sensing unit 61a is provided, the controller 51 ignores the detection result of the touch sensing unit 67 when the touch of the finger is sensed for more than a predetermined time by the third sensing unit 65. The touch input may not be performed.

Center combination input CM , CP )

In the present specification, the central combined inputs CM and CP are assumed to be performed simultaneously with either the first direction input M or the second direction input P.

For example, when performing the first direction input M as shown in (b) of FIG. 62, while pressing the center input key 13 shown in FIG. 61, the input unit 10 is moved to a predetermined first direction indication position ( While moving toward M ₁ , M ₂ , ..., or while performing the second direction input P as shown in (c) of FIG. 62, hold down the input unit 10 while pressing the center input key 13. Tilt toward a predetermined second direction indicating position (P ₁ , P ₂ ,...).

81 is a conceptual diagram for explaining a method of inputting a central combined input (CM, CP).

For example, a case in which the first direction input M and the center input C are combined will be described with reference to the drawings. In the process of moving the input unit 10 to a predetermined first direction indication position M ₁ , When moving to the state where the angular input (C) is performed, the direction combination input (CM ₁ ) is performed, while if only the input unit 10 is moved without performing the central input (C), the first direction input (M ₁ ) is performed. .

Here, the center combination input CM and CP may be applied to the case where at least one of the first direction input M, the second direction input P, or the center input C is provided with two or more stage multi-stage inputs.

For example, as illustrated in FIG. 86, when the first direction input M is provided in two stages, the first direction input M1 ₁ and the central input C in one stage are combined. the central input combination (CM1 ₁₎ and the first direction input of the second stage (M2 ₁₎ and a central combined input of central input (C) is a combination of a two-stage (CM2 ₂₎ is possible.

On the other hand, the center of the, first by forming the one-way type (M) the configuration to the first stage, and the center input (C1, C2) in two stages, the first direction input (M ₁₎ and the first stage as shown in Figure 87 input (C1) by the central combination input of the combined first stage (C1M ₁₎ and a second direction input (M ₁₎ a central combination type of the two-stage central input (C2) the combined second stage of the (C2M ₁₎ is It may be possible to arrange.

Therefore, when the central combination input CM, CP is provided to perform, the first direction indication position (M ₁ , M ₂ , ...) and the second direction indicating position (P ₁ , P ₂ , ..) Since characters can be assigned to each other, the input capacity (the number of characters that can be input) can be increased without additional configuration.

In the above two cases, the central combination input CM and CP may be combined with the second direction input P instead of the first direction input M.

That is, the central combination input CM and CP may be combined without limitation the first direction input M and the second direction input P of all types described above and the above-described central input C of all types.

Meanwhile, the characters arranged by the central combination input CM and CP may be continuously changed according to the number of times the central input C is performed. For example, the first direction input and the second direction input result and the first direction input and the second direction input result may be differently set after the center input is performed once and the center direction is performed twice. As described above, if the results inputted by the first direction input and the second direction input are different according to the number of center inputs, the number of characters that can be input can be increased infinitely. Such a combination input is temporarily performed, and it is preferable to set the combination input to return to the first mode when the combination input ends.

Next, when the central input is performed as shown in FIG. 104, a menu such as a symbol, additional information, entertainment, a ringtone selection, an Internet connection, a phone book, and a screen setting may be activated in the first direction input direction. The user performs the first direction input M to select a specific menu (eg, 'screen setting') among the menus activated by the central input, and the sub-menu (eg, displayed by the result) is displayed. Standby screen setting, function screen setting, font setting, menu method setting, illumination time setting, screen brightness setting, etc., which are displayed according to the 'screen setting' menu selection, may be performed as the second direction input (P). Since the center input, the first direction input, and the second direction input can be performed in one operation connected, the required function can be selected very quickly.

Direction combination input MP , PM )

In the present specification, the direction combination input MP or PM refers to the input operation when one of the first direction input M and the second direction input P is performed in succession while the other is performed in succession. It is assumed that the third character assigned to is input.

That is, as shown in (b) of FIG. 62, the direction combination inputs MP and PM perform the first direction input M first, that is, the input unit 10 receives the first direction indication position M. FIG. In the state of moving to the second direction input (P) as shown in (c) of FIG. 62 is performed or vice versa.

82 is a conceptual diagram for explaining an input method of the direction combination input MP and PM.

FIG. 82A illustrates a case in which the second direction input P is successively performed while the first direction input M is first performed, and the direction combination input M ₁ P ₁ is the input unit 10. Indicates a case where the second direction input P is performed to the second direction indication position P ₁ while the is moved to the first direction direction position M ₁ .

In contrast, (b) of FIG. 82 illustrates a case in which the first direction input M is successively performed while the second direction input P is first performed, and the direction combination input P ₁ M ₁ is the second direction indicating position. (P ₁₎ to indicate a second direction input (P) of claim 1 in a state of performing a direction instruction position (M ₁₎ in the first direction when the input (M) is performed.

When the first direction input M is performed while the second direction input P is performed first, the first sensing unit 61 is shown in FIG. It may be disposed around the second sensing unit 63 corresponding to).

Here, the first direction indicating positions M ₁ , M ₂ ,... And the second direction indicating positions P ₁ , P ₂ ,... Can be combined in all directions.

That is, as shown in (a) of FIG. 82, the second direction input P is input to the second direction instruction position P ₄ while the input unit 10 is moved to the first direction instruction position M ₂ . If this is done, the direction combination input M ₂ P ₄ is performed.

As described above, the direction combination inputs M ₁ P _{1 and} P ₁ M ₁ may have different characters according to the order of the first direction input M and the second direction input P which are combined. However, the same characters may be input regardless of the combination order.

That is, the same character may be input by the direction combination input M ₁ P ₁ and the direction combination input P ₁ M ₁ .

On the other hand, if the direction combination input (MP, PM) is not provided possible, even if the first direction input (M) and the second direction input (P) is performed at the same time, each input is of course performed independently.

That is, in the embodiment illustrated in FIG. 63, when the second direction input P for inputting 'ㅗ' and the first direction input M for inputting 'b' are simultaneously performed, a new combination Rather than entering characters, the Hangul character 'no' is entered by each input operation.

On the other hand, according to the movement of the first direction input (M) can be set differently the character input to the second direction input. For example, when the first direction input M is movable in eight directions as shown in FIG. 105, when the first direction input is performed in a specific direction, special characters are input by the second direction input, and the other specific direction is input. When the first direction input is performed, a number may be input by the second direction input. As described above, if the type of characters input by the second direction input is arranged depending on the first direction input, special characters, numbers, and alpha bell case can be input without changing the input mode.

In addition, when one or more of the first direction input M and the second direction input P are provided to enable two or more stages of multi-stage inputs, the direction combination inputs MP and PM correspond to the number of combinations corresponding thereto. It can be generated to maximize the input capacity. Therefore, it is preferable to input characters having 50 or more phonemes, such as Chinese characters or Japanese characters, through the direction combination input MP and PM.

Here, the above-described center input C, the center combination input CM, CP, and the direction combination input MP, PM may be freely combined in addition to the first direction input M and the second direction input P as necessary. Of course, it is also possible to change the number of direction indicating positions in each input without limitation.

Directional rotation input (R)

In the present specification, the direction rotation input (R) means that the input unit 10 inputs the assigned character or data while rotating itself in the left and right direction about the reference position on the base 110.

Rotation of the input unit 10 may be implemented in various ways. For example, as illustrated in FIG. 83A, the first support unit 25a and the second support unit 25 may move relative to each other. It can divide and provide by the support part 25b.

Here, the first support portion 25a may be fixed, and the second support portion 25b may rotate in the direction of the first support portion 25a, or vice versa.

Rotation sensing parts 68a and 68b are provided between the 1st support part 25a and the 2nd support part 25b in a rotation direction, respectively.

Accordingly, when the input unit 10 is rotated in the right direction R1, the first support unit 25a rotates to detect the rotation in the rotation detecting unit 68b, and when the input unit 10 is rotated in the left direction R2, the first support unit 25a rotates. The sensing unit 68a detects rotation.

Alternatively, as shown in (b) of FIG. 83, a rotation protrusion 77 is formed on one side of the input unit 10, and the left and right sides of the rotation protrusion 77 are respectively rotated in the direction of the rotation distance of the rotation protrusion 77. The rotation sensing units 68c, 68d, 68e, and 68f sequentially arranged may be provided.

The left and right rotation of the input unit 10 can be rotated in two stages according to the rotation distance (or rotation angle). That is, when the input unit 10 is rotated one stage to the right, the first rotation detection unit 68c on the right side of the input unit 10 rotates. When the first rotation is sensed, and the second rotation detection unit 68d on the right side detects the second rotation when the second rotation detection unit 68 rotates the input unit 10 further to the right.

On the other hand, in each case described above, the input unit 10 may have various rotation angles as needed, for example, as shown in (a) or (b) of FIG. 83, rotate only by a predetermined angle. Of course, it may be rotated more than one rotation (360 degrees).

In addition, in the direction rotation of the input unit 10, the same data may be input to all the pressing units 11, but different data may be input to each pressing unit 11 in combination with each pressing unit 11. have.

Array of characters

In the present specification, the term "character" means a character having a narrow meaning according to each language, such as Korean, English, or Japanese.

However, data that can be input in the character input device according to the present invention is not limited to the above characters, and may include various function commands such as numbers, symbols or enters, spaces, and cancellations.

In addition, in the present specification, a "vowel" in the case of a foreign language corresponds to a Korean vowel, or when the alphabet of the foreign language is divided into two types according to linguistic classification criteria, it is assumed to belong to a relatively small number of alphabet groups.

In the character input device 1 according to the present invention, the above-mentioned first direction input M, second direction input P, center input C, center combined input CM, CP or direction combined input ( There is no particular limitation on the method of arranging characters in MP, PM).

However, for more efficient character input, it is possible to arrange characters in the following manner.

First, in arranging the characters of each country, input of consonant characters and vowel characters may be input by different input operations.

For example, the consonant characters may be input by the first direction input M, and the vowel characters may be input by the second direction input P, or vice versa.

this is. Since the user can immediately associate a character input for each input operation, there is an advantage that the user can easily become familiar with the character input apparatus 1 according to the present invention.

84 is a table showing an example of arrangement of characters of each country according to the embodiment described above.

Referring to the drawings, consonants of characters of each country may be arranged in the first direction input M of two stages, and vowel characters of characters of each country may be arranged of the second direction input P of two stages.

At this time, the consonants and vowels are basically divided into the first direction indicating positions (M ₁ , M ₂ , ...) and the second direction indicating positions (P ₁ , P ₂ , ..), but in the case of Korean characters Vowels 'ㅒ' and 'ㅖ' are arranged at the first direction indication positions (M ₁ , M ₂ , ...), or in the case of alphabets, consonants 'V, Z' are second direction indication positions (P ₁ , P ₂ ,. Of course, they may be assigned to different direction indication positions as necessary.

In this case, in addition to the vowel, the second direction command position P ₁ , P ₂ ,.

In addition, in the case of the alphabet, a continuous character with a high frequency of use, for example, 'CH' or 'ING', may be assigned to one direction indicating position.

Here, in addition to the vowels 'A, E, I, O, U' of the alphabet, 'W, X, Y' has the same effect as vowels and is defined herein as a vowel.

Meanwhile, a mode change window may be assigned to the central input C1 at the first stage, and a mouse mode switching function may be assigned to the central input C2 at the second stage.

As shown in (a) of FIG. 85, four second direction indicating positions P ₁ , P ₂ , .. are provided, and the second direction input P is provided to enable input in two stages. In this case, when arranging the alphabet, 'A, X', 'E, I', 'W, Y', 'O, U' are assigned to the second direction indication positions (P ₁ , P ₂ , ..), Each of the above-mentioned characters assigned by the second direction input P of the first and second stages may be distinguished and input.

That is, 'E (P1 ₂ )' may be input by the second direction input P in one stage, and 'I (P2 ₂ )' may be input in the second direction input P in the second stage. .

Alternatively, when arranging Hangul characters, as shown in (b) of FIG. 85, 'ㅏ, ㅑ', 'ㅓ, ㅕ', 'ㅗ, ㅛ', 'TT, ? 'Can be duplicated and assigned so that the respective characters allocated by the second direction input of the first and second stages are distinguished and input.

Of course, contrary to that shown in Fig. 85, the first direction input M has four first direction indication positions M ₁ , M ₂ ,... The vowel character can also be entered by M).

In the case of arranging letters of similar shape as described above in the alphabet and Korean, the shape of the vowel character is associated with the second direction indicating positions P ₁ , P ₂ ,.

Particularly, in the case of Hangeul, if the vowels are arranged in the East, West, South, and North as described above, the shape of the vowel is reminiscent according to the direction, so the user can easily become familiar with it. have.

Alternatively, in the alphabetical arrangement, similar characters may be arranged in a bundle.

For example, 'b, d', 'p, q', 'i, j', 'm, w', 'u, v', 'k, x', 'c, o', 'a, e assign two characters to the same direction indication position, such as', 's, z', 'l, r', 'f, t', 'n, h', 'y, g', The input may be distinguished from each other by two multi-stage inputs.

Alternatively, any one of the two bundled characters may be assigned to the first direction input M, and the other may be assigned to the second direction input P.

Meanwhile, any one of a number, a symbol, various function commands or a mode change may be performed by either the first direction input M or the second direction input P, and by the central input C Various function commands, such as switching the input mode or pressing enter or OK, may be performed.

In this case, the call mode may be performed as a call / end button.

On the other hand, the character input device 1 according to the present invention may perform the function of a mouse which is an input device by using the input unit 10, in this case, the first direction input (M) of the input unit 10 in the mouse input mode ), The pointer can be moved by the second direction input P or the center input C and the second direction input P by the left / right button or scroll function of the mouse.

In this case, in the second direction input P, the input unit 10 may be divided into two ends so that the left portion corresponds to the left mouse button and the right portion corresponds to the right mouse button. The left portion may correspond to the left mouse button, the right portion to the right mouse button, and the upper and lower portions correspond to the mouse wheel by dividing into four 'X' shapes.

In this case, when the first direction input M is performed while the second direction input P in the direction corresponding to the left mouse button is performed, dragging or dragging is possible as in the mouse. In addition, when the center input C is performed while the second direction input P in the direction corresponding to the left mouse button is performed, 'Zoom in' causes the second direction input P corresponding to the right button of the mouse. If you perform the center input while doing so, you can set it to perform 'reduction'. That is, according to the pressing direction of the second direction input, 'zoom in', 'shrink' or 'open window', 'close window', 'rotate' and the like may be performed. The signal processing associated with this can be used as the signal processing method in a mouse generally used.

Alternatively, when the first direction input M is performed in multiple stages, the movement speed of the mouse pointer may be adjusted step by step.

Here, the above-described conversion to the mouse mode may be performed using a separate mode switch key 121, but may also be performed through the input unit 10. For example, the input unit 10 may be moved in the circumferential direction. In this case, the input mode may be switched by performing the central input C of one or two stages or performing the first direction input M in two stages.

When the central input C is performed, an input mode change window for moving to other modes is displayed, and the user can move to various modes through the first direction input M or the second direction input P. FIG.

Alternatively, various modes, for example, Korean input mode, alphabet input mode, numeric input mode, and symbol input mode through the first direction input M or the second direction input P while the central input C is performed. You can select the mouse mode. That is, while the center input C is maintained, the respective input modes are displayed in the character display unit 72 or the keyboard display unit 74 instead of the characters originally assigned to the direction indication positions.

100 to 102 illustrate examples of keyboard layouts when the input unit 10 is provided in two sets of left and right.

First, FIG. 100 shows an example in which the first direction input M and the second direction input P each have eight direction indicating positions, and are composed of two stage inputs.

Here, 'N' or 'M' in the center is the central input (C), the outermost two lines are made by the first and second direction inputs (M) of 1,2 stages, and the middle two lines are the 1,2 stages. Represents the data input by the second direction input P of.

The characters are arranged in one stage of the first direction input M and one stage of the second direction input P of each input unit 10.

100 (a) shows a basic input window in which data of 26 characters, 10 numbers, 12 F keys, 10 function keys, 4 direction keys, 2 changeover keys, and 64 data are all arranged. .

Symbols and other low-keys may be arranged in a Next window which is converted by selecting an N-key provided in the center of the left keyboard 74 (see FIG. 100 (b)).

Alternatively, the direction keys may be arranged in the second direction input P, the F keys may be arranged in the next window, and the symbols may be arranged in the basic input window.

On the other hand, when the 'M' key provided in the center of the right keyboard display unit 74 'is selected, the screen changes to the mouse input window shown in FIG.

Here, the next window and the mouse input window may be used as the central combined input (CM, CP), for example, the previous input when the finger is released after performing the central combined input (CM, CP) in a predetermined input window You can also return to the window.

On the other hand, in the case of using the above-described central sensing function in the character input device 1 according to the present invention, each character distinguished by the input method can be displayed separately.

That is, α in FIGS. 101 and 102 represent characters input when the second direction input P is performed while the finger is in contact with the central input key 13, and β in FIGS. It shows the character that is input when only the two-way input (P) is performed.

In this case, since the input capacity allocated to the second direction input P is doubled, 16 characters per input unit 10 and a total of 32 characters can be arranged.

  Therefore, in the embodiment shown in FIG. 100, the maximum number of data that can be arranged in one keyboard display unit 74 is 16 by the second direction input M of two stages and the second direction of two stages. 16 by input (P), 16 by combination of central input key (13) and second direction input (P), and 2 by central input (C) of two stages. Data arrays are possible, and in the case of two sets, a total of 100 data arrays are possible.

Therefore, you can arrange all the keyboards of the currently used keyboard in one window without the next window.

101 and 102 show keyboard display examples in a small device such as the portable mobile communication terminal 100. FIG.

Referring to the drawings, FIG. 101 illustrates a case in which the first direction input M and the second direction input P each have eight direction indicating positions and are configured in one stage. FIG. 102 shows four direction indicating positions, respectively. And a case consisting of two stages.

Here, the outer line of FIG. 101 and the outer two lines of FIG. 102 are input by the second direction input P, and the inner line of FIG. 101 and the inner two lines of FIG. 102 are input by the first direction input M. FIG. 101 and 102 denote data input when each second direction input P is performed without placing a hand on the input unit 10.

In particular, in FIGS. 101 and 102 (a), the left side represents the mouse input window, the right side represents the basic input window, (b) the alphabet input window, the left side of (c) the numeric input window, and the right side the basic input. Display the window.

Thus, in both embodiments, when the 'alphabet' key of the right keyboard display portion 74 'in (a) is selected, both are changed as in (b).

At this time, if the arrow on the center is selected on the left side of (b), it is converted to the mouse mode of (a), and when the 'B' key on the right side is selected, it is converted to the basic input window.

Alternatively, when the 'number' key of the right keyboard display unit 74 'of (a) is selected, the right keyboard display unit 74 is fixed and only the left keyboard display unit 74' may be converted into a mouse input window. .

The embodiments shown in FIGS. 101 and 102 are arranged such that letters, numbers, F keys, symbols, etc. may be inputted through mode change, unlike the embodiments shown in FIG. 100.

Therefore, in this case, the first direction input M and the second direction input P can be configured in one stage, or the number of direction indication positions can be reduced to four.

Character input device 1 according to the present invention may be provided in the base 110 or more.

FIG. 88 is an operation diagram illustrating an input example in a state in which two left and right input units 10 and 10 'are provided on the base 110 of the portable mobile communication terminal 100.

In this case, the two input units 10 and 10 'may be provided in the same configuration or may be provided in different configurations.

That is, the input unit 10 on the left side is provided with the first direction input M, the second direction input P, and the center input C, and the input unit 10 'on the right side has the first direction input M. In addition to the second direction input P and the center input C, the center combined input CM and CP or the direction combined input MP and PM may be provided.

In addition, the number of direction indicating positions may be different from each other, and either side may be provided to enable two-stage input.

90 is a conceptual diagram illustrating an example of the configuration of each input unit 10, 10 'when the input units 10, 10' are provided in duplicate.

Referring to FIG. 90 (a), each input unit 10, 10 ′ is composed of two first direction inputs M and two second direction inputs P, wherein the first direction indication position ( M ₁ , M ₂ ,... And eight second direction indicating positions P ₁ , P ₂ ,.

Accordingly, the number of characters that can be input through the input units 10 and 10 'is 16 through the first direction input M and 16 through the second direction input P, except for the central input C. A total of 32 pieces are provided, and since the input units 10 and 10 'are provided with two left and right, the total number of characters that can be input is 64.

This is an input capacity remaining even after arranging 24 Korean characters and 26 alphabetic characters. Therefore, one operation and one phoneme can be input, and a symbol, a number, or various function commands may be additionally input to the remaining direction indication position.

Therefore, letters, numbers, symbols, etc. can be directly input without changing a mode, thereby enabling rapid character input.

For example, a character is input by the second direction input P of two stages of each of the two input units 10 and 10 ', and the mouse pointer is moved by the first direction input M, enter, Function commands such as space and cancellation, mode change, direction indication input, etc. can be performed. Through the direction indication input, cursor movement, menu movement, channel / volume adjustment, and the like can be performed.

Here, the first direction input (M) may be composed of only one stage input, as shown in (a) of FIG. 21, when configured as a two-stage input, numbers, symbols, etc. may be further arranged Of course.

On the contrary, a character is input by the first direction input M of two stages of each of the two input units 10 and 10 ', and a function command, a mode change, and a direction command input are input by the second direction input P. Or the like.

Alternatively, when the two input units 10 and 10 'have eight first direction indicating positions M ₁ , M ₂ ,... And eight second direction indicating positions P ₁ , P ₂ ,... The letters may be arranged in only one stage of the first direction input M and one stage of the second direction input P.

Alternatively, as shown in (b) of FIG. 90, the two input units 10 and 10 ′ may respectively have first direction indicating positions M ₁ , M ₂ ,... And second direction indicating positions P _1. In the case of having 4, P ₂ , ..), characters may be arranged in the first direction input M of the multi-stage and the second direction input P of the multi-stage.

Alternatively, any one input unit 10 inputs a character, and the other input unit 10 'performs the above-described movement of a mouse pointer, a function command, a mode change, a direction command input, or a number. Alternatively, an input such as a symbol may be performed.

In this case, text input and mouse can be used at the same time, and the effect of using both the keyboard and mouse at the same time on a desktop computer can be obtained. There is an advantage that can be performed in the terminal.

Even in the above-described case, when one or more of the first direction input M or the second direction input P is configured in two stages, the numbers, symbols, etc. may be further inputted.

FIG. 91 is a conceptual diagram illustrating the configuration of the input units 10 and 10 'according to another exemplary embodiment, and each illustrates only one of two input units 10 and 10' having the same configuration.

First, in the case of (a) of FIG. 91, the first direction input M has eight first direction indication positions M ₁ , M ₂ , ..., and the second direction input P has four It has a second direction indicating position (P ₁ , P ₂ , ..).

On the contrary, in the case of (b) of FIG. 91, the first direction input M has four first direction indication positions M ₁ , M ₂ ,... It has two direction indication positions (P ₁ , P ₂ , ..).

Therefore, in each embodiment, since the total number of characters that can be input through one input unit 10 is 12, a total of 24 characters may be input through two input units 10 and 10 '.

Here, if one of the first direction input M and the second direction input P is configured as a two-stage input, the number of allocated characters can be further increased.

In this case, the first direction input M has eight first direction indication positions M ₁ , M ₂ , ..., and the second direction input P has six second direction indication positions P _1. , P ₂ , ..).

That is, if the first direction input M is configured in two stages in FIG. 91A, a total of 20 characters can be assigned to one input unit 10, and the second direction input P is configured in two stages. In this case, a total of 16 characters can be allocated.

When the input unit 10 is provided in the base 110 in duplicates, the characters assigned to each of the input units 10 and 10 'and the input operation may be arranged in various ways.

For example, a vowel character may be assigned to only one of the two input units 10 and 10 ', or the first direction input M or the second direction input performed by each of the input units 10 and 10'. The vowel may be divided and assigned to any of (P).

On the other hand, when the mouse mode is switched, the movement of the pointer may be performed by one of the two input units 10, and the manipulation of the pointer may be performed by the other.

Signal combination

The input device of the present invention can input third data different from the original by combining two or more of the first direction input, the second direction input, and the center input.

This will be described in detail with reference to FIGS. 109 to 112.

FIG. 109 is a diagram illustrating a combinational input of a center input, a first direction input (direction shift input) and a second direction input (direction push input). FIG. In the drawings, the letters a, b, c, and d are assigned to each direction of the first direction indication position, and the letters 'b', 'ㅓ', and 'b' are assigned to each direction of the second direction indication position. The letters ',' and 'ㅜ' are assigned.

When the input unit moves in the west direction, the letter 'ㄹ' assigned to the first direction indication position in the corresponding direction is input. However, if the input unit is moved in the north direction while performing the center input (①) (②), the 'number mode' assigned to the north direction is activated, and the direction pressing keyboard has 'ㅏ', 'ㅓ', The numbers “1, 2, 3, 4” are assigned instead of “ㅗ” and “TT”. Subsequently, when the input unit is oriented in the west direction, the number '4' is input by the direction pressing input.

Referring to FIG. 110, when the center input is performed after the direction movement input, FIG. 110 shows that other characters are input in addition to the characters assigned to the direction movement input. For example, 'b' is input when only the direction movement input is performed in the 12 o'clock direction, but the symbol '?' Is input when the center input is performed after the direction movement input.

111 shows a combination of the direction movement input, the center input, and the direction pressing input. For example, if the center input is performed after the direction moving input of the input unit 10 in the 12 o'clock direction and the direction push input is sequentially performed in the 9 o'clock direction, the symbols ',' are input.

112 illustrates an example in which the direction movement input, the center input, and the direction movement input are combined in multiple stages. That is, after performing the direction movement input to the 9 o'clock direction, if the center movement is performed and the direction movement input to return to the reference position is performed again, the symbols ',' are input.

In this case, instead of the direction movement input, the direction pressing input may be combined with the center input, and the direction movement input and the direction pressing input may be interchanged and combined.

That is, the direction input in the signal combination is the direction movement input or the direction pressing input. That is, although the embodiments have been described based on the direction movement input, the above embodiments may be combined with the direction pressing input.

On the other hand, the dial that is reset by the center input does not necessarily have to be a letter, but special symbols (!, @, #, $,%, ^, &, *, Etc.), function keys (F1 to F12), numbers, and menu sets. (Additional information, entertainment, phone book, internet access, screen settings, sound settings, message writing) can also come.

As described above, the present invention can set various letters, numbers, and menus by the combination of the direction movement input, the direction pressing input, and the center input. Such a function can quickly perform various characters and functions not pre-assigned by the central input without changing the mode. Although described herein based on the direction movement input, it may be combined with the direction pressing input in addition to the above embodiment.

In addition, the present invention can provide an input unit with a bee, the direction movement input, the direction pressing input, the center input, the combination of the direction movement input and the center input, the combination of the direction pressing input and the center input, the direction pressing input and the direction pressing input And a combination of the central input, the input and the combination can be processed in multiple stages, and thus all characters can be input without changing the mode.

For example, assuming that the first character is input in the direction movement input, the second character is input in the direction pressing input, and the third character is input in the combination of the direction movement input and the center input. It is possible to input a total of 24 characters by 8 characters by 8 characters, 8 characters by direction push input, and 8 characters by a combination of direction movement input and center input.

On the other hand, in the case where four direction indication positions are provided, four characters are inputted by the direction movement input, four characters by the direction pressing input, and a total of 12 characters are inputted by four characters by the combination of the direction movement input and the center input. If the input unit is composed of two sets, a total of 24 characters can be input.

On the other hand, when four direction indication positions are provided, 16 characters can be input by direction combination input (that is, the other one is performed while the direction movement input or the direction pressing input is performed). In this case, 32 characters can be input. Of course, in the above case, since four direction movement inputs and four direction pressing inputs can be independently performed, 48 characters can be input as a result.
