Description

Technical field

The present invention relates to a data input device, and more particularly, to a data input device in which the traditional input method by input keys is improved, so that single-step input and two-step input can be performed independently by a single input key, and in which Raman input is further performed, sequential input, and buffered input so that the input capability is maximized, and so that input can be quickly and correctly performed by a limited number of Avis input.

State of the art

Recently, software semiconductor technologies and information processing technologies have undergone significant development, a variety of information devices, such as mobile phones and personal digital organizers (PDAs), have gradually become more miniature and multifunctional. In addition, the importance of preserving information and communications by entering characters into information devices has increased.

However, input devices of various symbols or commands in the currently used information devices have many problems, so that the information devices cannot properly correspond to the changes described above in the information sphere.

Namely, what is most important for character input is the ability to quickly and correctly enter information. Therefore, it is preferable that the required characters be correctly entered through a minimum number of operations.

In this regard, a separate input key must be set for each input character in the preferred input device, which means that at least 100 input keys are required, including 24 Korean characters, 26 English characters, 10 digits and a variety of characters.

In particular, there are restrictions for increasing the number of input keys due to space limitations in small information devices such as a mobile communication terminal or PDA. Namely, in the case of a mobile communication terminal, in which 12 input keys are provided in a 4 × 3 arrangement, when 24 Korean characters or 26 English characters are located on 12 input keys, two or three characters are duplicatedly assigned to one input key.

Therefore, in a traditional data input device, in order for the user to select the desired character, since the input keys must be actuated repeatedly, the input time is long and there is a high probability of erroneous typing and operations during a complex input process, so that the input accuracy is deteriorated .

On the other hand, in order to solve the problems described above, the Korean character input device for an electronic device in which, after the consonants and vowels of the Korean characters are located on the touch screen and enter the consonant by initial touch, a hobby performed on the touch screen for entering a vowel.

In this case, to simplify the appearance of the screen, vowels are not displayed on the touch screen. However, since vowels are inputted by entrainment, the entrainment path for the user is not uniform, so that the visual control is impaired, and input accuracy is low, and the input path according to the entrainment is long and complex, so the input time is increased.

Additionally, when consonants and vowels are located on the touch screen, all the necessary phonemes are located in a limited space, so that the space assigned to each phoneme is too small, and it is impossible to correctly touch only the desired key if there is an obstacle from the other key during quick phoneme entry. Therefore, input tools such as a stylus should be further provided. However, you cannot quickly enter characters using the stylus.

In particular, in the case of input, characters are entered using the touch screen described above, it is impossible to enter characters in a mobile phone and computer for which the touch screen is not used. Therefore, additional costs are increased since a touch screen and a character recognition module must be provided.

Variants of the invention

A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, so that any person skilled in the art can easily implement the present invention.

The first implementation option

The data input device according to the first embodiment of the present invention comprises a plurality of input keys 10, in which a single-step input for inputting a first character and input of a second step for inputting a second character are independently provided, a sensor 20 for detecting a single-step input, and input of the second step is performed using keys 10 input, and a controller for extracting the first character or second character, duplicating the assigned keys 10 of the input, depending on the results of the detection sensor 20 for inputting the extracted first character or second character.

Referring to FIG. 1, a mobile communication terminal 100 comprises a predetermined input area P and a housing 110 in which a display 130 is provided.

A plurality of input keys 10 are provided in an input zone P provided in the housing 110. A display 130 on which characters entered by the input keys 10 are displayed is provided on one side of the housing 110. Here, as illustrated in FIG. 1, the input zone P can be provided in the housing 110 and may be provided on the display 130.

Namely, the input method according to the present invention can be implemented on a touch screen or touch panel. In this case, touch input is performed so that data is displayed on the touch panel or touch screen and an additional pressure sensor is provided under the touch panel or touch screen so that input by pressure can be performed.

The above can be generally applied to all implementations, which are referred to below.

The input key 10 may take a variety of forms. For example, as illustrated in FIGS. 3 and 4, the input key 10 may be a cylinder, a polygonal cylinder, or a rectangle, so that one portion of the input key 10 faces outward through a through slot 14 provided in the housing 110.

As illustrated in FIG. 3, the input keys 10 are separated from the housing 110, so that the input keys 10 move independently. However, the input keys 10 are integrated with each other, so that the transformation can be carried out by pressing the corresponding sections on the input keys 10.

For the input key 10, it is provided that a single-step input for inputting a first character and a two-step input for inputting a second character are performed independently.

Here, the structures illustrated in FIGS. 3 and 4 are only an example for realizing input by touch and input by pressure.

Here, a single-stage input and a two-stage input can be provided in various ways. For example, the input of the first step may be provided as input by touching in accordance with the contact or the proximity of the input keys 10, and the second input may be provided as input by pressure, so that the input keys 10 move up and down.

Single-stage input and two-stage input can be provided as input by pressure, distinguished by the amount of movement of the input keys 10 up and down or the pressure value.

On the other hand, as illustrated in FIG. 34, the plurality of first input keys 11 are arranged in a circle, and it is provided that a single-step input for inputting a first character and a two-stage input for inputting a second character by pressure are independently performed, and a second key 12 may further be included. an input provided inside or outside the first input key 11 to enter the seventh character by touch or pressure. Next, touch input and pressure input will be described with reference to FIGS. 3 and 4.

Figures 3 and 4 illustrate various embodiments of input keys 10 using touch input as a single-step input and pressure input as a two-stage input.

Touch input means that the first character assigned to the input key 10 is entered by detecting the contact or by approximation on the input keys 10. Since touch input is detected by the touch sensors 30, it is contemplated that the touch sensors 30 correspond to the input keys 10, so that the touch sensors 30 detect that the user's fingers are contacting the input keys 10 or are close to the input keys 10 within a predetermined distance.

Various types of materials can be used as touch sensors 30. For example, touch sensors 30 may be formed by a proximity sensor, such as an optical sensor and an ultrasonic sensor, and may be formed by a contact / proximity sensor, similar to electrostatic capacitance sensors 31.

As illustrated in FIG. 3A, the electrostatic capacitance sensor 31 includes a conductive contact element 32 that comes into contact with the input key 10, and a measuring element 33 for measuring the electrostatic capacitance of the contact element 32.

When the user's fingers make contact or approach the input keys 10, a charge in the electrostatic capacitance is generated by the contact member 32.

The measuring elements 33 measure the charge in the electrostatic capacitance generated by the contact element to transfer charge in the electrostatic capacitance to the controller. The controller determines that an effective signal is received when the charge in the electrostatic capacitance is not less than a predetermined value for performing input by touch. When the keys are contacted and pressed by the user's fingers, the magnitude of the electrostatic capacitance changes, so that multi-step input can be performed.

Here, when the contact member 32 does not extend to the upper surface of the input key 10, a contact body 34 may further be provided for electrically connecting the contact member 32 and the upper edge of the input key 10 to each other. Here, FIG. 3B is a combined section of FIG. 3A.

Fig. 4A illustrates a housing in which a contact member 32 is provided on the upper edge of an input key 10 and a measuring element 33 is provided on a printed circuit board (PCB) 140.

In this case, between the contact element 32 and the measuring element 33, a connection line 35 may additionally be provided for transmitting the electrostatic capacitance generated by the contact element 32 to the measuring element 33.

When the input key 10 contains conductive material, as illustrated in FIG. 4B, a conductive elastic element 36 may be provided, provided between the input key 10 and the PCB 140 to transmit the electrostatic capacitance generated by the contact element 32 to the measurement element 33.

Here, the conductive elastic member 36 functions as a return member, restoring the initial position of the input key 10 when input is performed by pressure, and also electrically connects the input key 10 and the PCB 140 to each other.

Touch sensors 30 may be located in the input zone P in a variety of ways. For example, one touch sensor 30 may be provided on each input key 10. As illustrated in FIG. 5A, a plurality of touch sensors 30 may be located throughout the input area P. As illustrated in FIG. 5B, touch sensors 30 may be located in the input zone, forming gratings along the X and Y axes.

On each input key 10, two or more touch sensors 30 may be provided.

Pressure input means detecting the up and down movement of each input key 10 to enter the first character or second character assigned to the input key 10.

Therefore, pressure sensors 40 are provided to correspond to the input keys 10 and for detecting up and down movements of the input keys under pressure.

Pressure sensors 40 can detect movements of all input keys 10 and can detect movements of a portion of input keys 10. In the case of the latter, for example, an electric element can be provided in the center of the input keys 10, and a pressure sensor can be provided under the elastic element for detecting pressure when the input keys 10 are pressed.

A pressure sensor 40 of various kinds may be provided. For example, a pressure switch, switched in accordance with the up and down movements of the input key 10 under the influence of pressure, or a pressure sensor for detecting the pressure applied to the input key 10, can be used as the pressure sensor 40.

When a membrane switch or contact pressure sensor is used as the pressure sensor 40, as illustrated in FIG. 4B, a returning element may further be provided to return the input key 10 on which pressure input is initialized.

On the other hand, pressure plates 41 may be further provided provided between the input keys 10 and pressure sensors 40 connected and separated from the pressure detection units 40 in accordance with the movements of the input keys 10.

Alternatively, a multi-step input of two or more steps can be performed by inputting a pressure depending on the up and down travel distance of the input key 10 or the amount of pressure applied to the input key 10.

Namely, when multi-stage pressure input is performed in accordance with the pressure distance, two or more pressure sensors 40 are sequentially provided on the path of the input key 10, separated from each other to detect the degree of movement of the input key 10.

Therefore, when it is provided that the pressure has two steps, since one input key 10 can perform three operations, such as input by touching from one step, input by pressure from one step, and input by pressure from two steps on one input key 10, so that three characters can be entered with a single key, the ability to enter the 10 input key is increased three times.

In the case of pressure input, it is possible to obtain a similar effect by pressure input from one stage, input via pressure from two stages, and input via pressure from three stages.

Here, when the pressure input is formed from a multi-stage input of two or more stages, a snapping unit allowing the user to feel the click is provided at one of many stages, so that the user can determine whether the pressure input is a multi-stage input.

Alternatively, multi-step input can be applied to a housing in which the input key 10 is divided into a first input key 11, a second input key 12, and a third input key 13. Additionally, multi-stage input can be applied to the input conversion unit 55 and to an internal input unit other than the input key 10.

On the other hand, the controller can selectively determine input by touching and input by pressure, carried out by the same input key 10, to perform input, and can perform input for all signals.

In particular, in the case of a data input device according to the present invention, since touch input is inevitably performed if input by pressure is performed, the controller must be able to select signals when a plurality of detected signals are received, so that input is performed according to the user's desire.

For example, as described above, in the case in which only input by means of pressure is performed by a given input key 10, although touch and pressure are simultaneously detected by the touch sensor 30 and the pressure sensor 40 corresponding to one input key 10, the controller can extract an input command to execute an input command from memory depending on the results detected by the pressure sensor 40 when the detected interval lies within a predetermined time.

In the case mentioned above, on the contrary, only touch input can be determined effective.

To execute an input command, the controller retrieves an input command called by input by touching and input by pressure in a variety of ways.

For example, when touch input is canceled by the specified delay time (contact hold time) after making touch input, the controller retrieves from the memory the characters assigned to the touch input and pressure input for the enter key 10 to execute the command.

In the case where Korean consonants are introduced, when input by touch or input by pressure is continuously detected twice within a predetermined time, double consonants can be entered.

When touch input or pressure input is continuously detected after at least a predetermined time, double consonants can be entered.

The input keys 10 can be arranged in various ways.

As illustrated in FIG. 1, input keys 10 may be arranged in a rectangle formed of two or more rows and columns.

In this case, the number of input keys 10 may be 12 of 4 × 3, which is generally used for the mobile communication terminal 100. As illustrated in FIG. 19, the number of input keys may be 8 at a 4 × 2 arrangement.

In the previous case, as illustrated in FIG. 7B, one key may be added so that thirteen input keys are provided.

When the number of input keys 10 is not less than 13, 26 English characters are located on the input key 10, so that two characters are provided on each input key 10. Therefore, the input is made in such a way that one input is an input by touch (or input by pressure from one stage) and the other input is input by pressure (or input by pressure from two stages).

и

In the case of entering Korean characters, 24 Korean phonemes are duplicated on 12 input keys 10, and other input keys 10 can be additionally provided to which phonemes are duplicated

and

As illustrated in FIG. 7B, an input converting unit 55 for converting a consonant to a vowel by performing combination input by input keys 10 can be further provided so that a vowel is entered.

In the case when the specified consonant and vowel are simultaneously assigned to the input keys 10, the consonant is entered by means of a single input made by the input key 10, and the consonant is converted to a vowel by the combination input (by simultaneously contacting the input keys 10 or the input keys contact within the specified time (figa)), which is implemented by block 55 conversion of the input.

An input conversion unit 55 may be provided in various positions. For example, an input conversion unit may be provided outside the input key 10, as illustrated in FIG. 7B, and may be provided inside the input key 10, as illustrated in FIG. 19A.

On the other hand, as illustrated in FIGS. 2 and 9, the input keys 10 can be arranged radially on a circle having a predetermined radius. In this case, the input keys 10 may be separated from each other for selection individually, or may be connected to each other to be integrated.

When the input keys 10 are separated from each other, the input keys 10 can be provided in four radial directions or in eight radial directions. In this case, the input keys 10 may be separated from each other for selection individually, or may be connected to each other to be integrated with each other.

When the input keys 10 are separated from each other, the input keys 10 can be provided in four radial directions or in eight radial directions.

The input keys 10 may be provided in five, six and seven radial directions.

When the input keys 10 are provided as two columns of the first input keys 11 and the second input keys 12 on a concentric circle, the number of the first input keys 11 may be equal to or different from the number of the second input keys 12. For example, the number of first input keys 11 or second input keys 12 is 4 and the number of other keys is 8.

When the input keys 10 are integrated with others or arranged in a separate ring, all of the input keys 10 can rotate. Therefore, scrolling, mode change, and various commands can be performed.

Additionally, as illustrated in FIG. 2, input keys 10 may be separately provided on a concentric circle of two or more columns and may be located on the same circle. Although the input keys 10 are arranged in a circle, as illustrated in FIG. 9C, an input conversion unit 55 may be provided.

On the other hand, two pairs of input keys 10 may be provided on both sides of the input zone P. Further, the data input device according to all embodiments may be in the form of two pairs, as illustrated in FIG.

'Quick Entry' as used herein means making an input while continuously touching or pressing a plurality of input keys 10.

For example, in the case of Korean characters, characters corresponding to the start sound, middle sound, and end sound are not input by independent input operations (namely, operations of separately pressing the enter key on a mobile terminal or computer keyboard), but are input during fluent input (or pressing) the input keys 10 in accordance with the paths on the input keys.

On the other hand, when a fluent input is performed in which either touch or pressure is carried out at least sequentially by means of three or more input keys 10, the controller selects some effective signals from among the plurality of input signals.

For example, to execute an input command, an input command is retrieved from the memory depending on the results obtained by detecting the initial input and the final input.

A signal can be defined as effective only when a predetermined delay time is detected (hold time is detected) or a range of movement. In the case in which the fluent input is bent in a direction that is not a linear direction when generating a plurality of input signals, only the input signal generated at the bend point can be processed as efficient.

All terminals are connected to each other so that data values of the point at which the signal is generated and data values of the point at which the signal is interrupted can be entered.

Here, with fluent input, input comprises input by touch, a mixture of input by touch and input by pressure, or input by pressure is performed by two or more input keys 10.

The first character and the second character are duplicated to the input keys 10. The first character is assigned for input by touch input (or input via pressure from a single stage if pressure input is used). The second character is assigned for input by pressure input (or input via two-stage pressure).

Here, the first symbol and the second symbol may be provided without limitation. For example, the first character and the second character can be various kinds of characters, such as the Korean character and the English character, and can be divided into consonant and vowel.

For example, in the case of English characters, vowels may be 'A, E, I, O, and U', and consonants may be 'W, X, and Y'. Here, the input keys 10 can be assigned a variety of characters, such as numbers and signs, as well as the Korean and English characters described above.

On the other hand, one or two or more Korean and English characters may be duplicated on the input keys 10. When a fluent entry can be performed, frequently used fused consonants and fused vowels are preferably fused on adjacent input keys 10.

Here, fused phonemes, including fused consonants or fused vowels, mean that frequently used words are arranged together, and that two phonemes are fused together in a word, such as a cluster of consonants in Korean characters and 'ch' and 'ng' in English characters.

For example, merged consonants are

в случае корейских символов и 'ае, еа, аu, yu, yo, ou, ех,…' в случае английских символов.in the case of Korean characters and 'ch, ng, ing, gh, ght, ...' in the case of English characters. Close vowels are

in the case of Korean characters and 'ae, ea, au, yu, yo, ou, ex, ...' in the case of English characters.

в случае корейских символов и 'ed, er, on, ion,…' в английских символах.Consolidated consonants and vowels obtained by mixing consonants and vowels with each other are

in the case of Korean characters and 'ed, er, on, ion, ...' in English characters.

In the example described above, in the case of 'ght' and 'ion', three characters are fused to the adjacent input keys and these three input keys 10 scroll, so that three phonemes are entered by running fluent input once. In this case, the controller determines as input-effective three or more input signals sequentially generated by fluent input.

The plurality of input keys 10 can be divided into a set C of consonant input keys to which consonants are assigned and a plurality of V vowel input keys to which vowels are assigned for arrangement.

“Consonant Keyboard C Keys” and “V Vowel Keyboard Combinations” according to the present invention mean a plurality of a plurality of input keys 10 to which consonants and vowels are assigned.

In the same set of input keys, the same characters are assigned and arranged. However, the input keys 10 are divided into a set of input keys when Korean characters, English characters, and Japanese characters are entered for convenience in accordance with the kind of assigned characters.

This separation does not have any additional meaning when signs and numbers are located and entered.

On the other hand, when the input keys 10 are divided into a set C of consonant input keys and a set of V vowel input keys, a set of C consonant input keys and a set of V vowel input keys can be arranged such that for the input keys 10, the consonant is touched in sequence and vowel or consonant, vowel and consonant.

The sets C of the consonant input keys and the V sets of vowel input keys can be arranged such that during fluent input, the input keys 10 successively touch in the order of consonant, consonant and vowel, or vowel, consonant and consonant.

Next, a specific example of a data input device according to the present invention will be described with reference to FIGS. 7-9. First, referring to FIG. 7A, on input keys 10 in the form of 4 × 3, the sets C of consonant input keys are divided into a first set of C1 consonant input keys from one column and a second set C2 of consonant input keys from three columns and a set of V keys vowel entries are provided in the second column.

.Two characters are duplicated assigned to the input keys 10 contained in the collection of C consonant input keys and in the aggregate V vowel input keys. Thus, the characters located on the input keys 10 are inputted by input by touching, and the characters (shaded areas) located below the input keys 10 are inputted by pressure. Therefore, when the user makes a fluent input only by entering by touching, sequentially entering characters

and

along the first trajectory (1), is introduced

.

When input by pressure is performed by the first set C1 of consonant input keys, and then input by touch is performed along the same path, is entered

along the second path (2), input by touch is continuously performed, input by touch and input by pressure.

Namely, in the data input device according to the present invention, the input keys 10 are divided into a plurality of V vowel input keys and a set of V consonant input keys, and a set of V vowel input keys are provided between the consonant input key sets C.

Therefore, a symbol consisting of a consonant and a vowel can be effectively entered through continuous operations during the input of this symbol.

For example, for

or

used during Korean character input, touch input and touch input along the fifth path (5) of FIG. 7 and touch input and pressure input along the sixth path (6), so that merged consonants can be input.

Namely, since in the data input device according to the present invention, the sets of V vowel input keys and the C consonant input keys C are located efficiently, and the merged consonant and the continuous vowel on the V and C input key combinations are adjacent to each other, it is possible to enter this character efficiently.

On the other hand, as shown in FIG. 7A, when performing fluent input, if necessary, it is possible to continuously carry out two or more touches or presses on the same set of input keys C and V in the form of a third path (3) or fourth path (4) .

In this case, the controller determines that only some of the detected results are effective for extracting the character from the memory and for entering the extracted character.

игнорируется.For example, the controller may determine that only one of the initial detected signal or the final detected signal is effective among a plurality of detected results. Namely, on the third path (3), when the controller determines that only the initial detected signal is effective in the aggregate of V vowel input keys, input

Therefore, when performing a fluent input only by touching, it is entered

when the initial detected signal is selected and fluent input is performed only by touch input, a

Here, in the method for determining the final detected signal, for example, in the case in which a plurality of detected signals are continuously generated, if the generation of the signal is stopped at some point in time, the signal is defined as the final detected signal.

In the case in which two or more fluent inputs are continuously detected in a predetermined interval, and for no less than a predetermined time, no subsequent detected signal is generated after a predetermined detected signal, the signal may be defined as the final detected signal.

на четвертой траектория (4)).In contrast to the example described above, with fluent input made using the enter key 10 on the same set of input keys C and V, the controller can determine the initial input and the final input or input by touch or pressure input made using the key as effective 10 input at the bend point (for example, the input key 10, which is assigned

on the fourth trajectory (4)).

Among the many detected input results obtained by the same set of input keys C and V, the controller can determine as effective only signals that are stored for at least a specified input time. Namely, this happens if the finger remains on the input key 10, which is assigned

, for at least a specified time (for example, one second) in order to enter on the fourth path (4)

wherein

or

ignored so that is introduced

In general, the detected signal is stored for at least a specified input time, when input starts (the position at which the finger first holds), when input stops (the position at which the finger rises), or when the input state is saved (the position at which the finger delayed for at least input time).

Therefore, through the operation of continuously specifying characters for input, only characters required for input can be easily entered and without additional training.

Here, the difference in input time is very small. However, the difference can be distinguished by setting the time to distinguish between valid input and invalid input. The input process by setting the input time (called setting the delay time) is used for a variety of electronic products and the scroll function of the touch panel.

On the other hand, in the case where the touch sensor 30 is formed by the electrostatic capacitance sensor, the input signal is determined to be effective only when the charge in the electrostatic capacitance in accordance with the degree of contact (area or power) is not less than a predetermined value.

On the other hand, in the case of inputting a double consonant, during a predetermined input time, input by touch is continuously performed twice or input by pressure on the input key 10 to which the corresponding consonant is assigned, input by touch or input by pressure is performed for at least a predetermined time delays, or touch input or pressure input, are performed while input is performed using an additional function key (not shown).

Referring to FIG. 7B, similarly to FIG. 7A, on input keys 10 with a 4 × 3 arrangement, the sets C of consonant input keys are divided into a first set C1 of consonant input keys from one column and a second set C2 of consonant input keys from three columns, moreover, V vowel input keys are provided in the second column, and the input conversion unit 55 is separated from the input key 10 by a predetermined distance provided on the left side of the first column and on the right side of the third column.

When an input conversion unit 55 is selected for the input key 10 belonging to the set C of consonant input keys, an input signal other than the signal assigned to the input key 10 is input.

Затем выполняют перемещение к клавише 10 ввода, которой присвоено 'S'. В это время касаются только клавиши 10 ввода, так что блок 55 преобразования ввода не выбран.Let us describe an example of entering the English word 'BUS' by means of the first path (1). First, in order to enter 'B', as illustrated on

simultaneously touch the input conversion block 55 and the input key 10. Then move to the input key 10, which is assigned to 'U'. Then move to the input key 10, which is assigned to 'S'. At this time, only the input keys 10 are touched, so that the input conversion unit 55 is not selected.

Here, among the plurality of detected signals in the plurality of V vowel input keys, only the initial signal is determined as effective, as described above.

Consider the second trajectory (2) to describe the input of the English word 'GET. When 'G' is entered, the input conversion unit 55 and the input key 10 must be touched. However, when T is entered, only the input key 10 needs to be touched.

On the other hand, a plurality of V vowel input keys may comprise 5 input keys 10, in contrast to a set C of consonant input keys located in a first column and a third column. In the case of Korean characters, an additional input key 10 may be provided

or

Когда выполняется ввод посредством касания и ввод посредством давления, вводится

In the case of English characters, 26 characters can be duplicated on 13 input keys 10 in two. Therefore, when touch input and fluent input along the third path (3) in FIG. 7B is performed,

When touch input and pressure input are input, input

Here, the input conversion unit 55 may have various forms. For example, the input conversion unit 55 may be a touch-type conductive terminal or an annular pressure button.

On the other hand, the input conversion unit 55 may perform functions other than the consonant conversion in other modes other than the character input mode. For example, when a side-to-side movement is performed while the touch of the input conversion unit 55 is maintained, volume control or a scroll function can be implemented.

On the other hand, as illustrated in FIG. 8A, a plurality of touch sensors 30 are located in the entire input area P or on the input keys 10, so that the controller determines that during a fluent input, the selection of the input key 10 is valid only when the touch is detected by the sensors 30 touch in the amount of not less than the specified number of the many sensors 30 touch located on the input keys 10.

In the data input device 1 according to the present invention, when performing a fluent input, in a case where during fluent input, movement is made to two or more input keys 10 by which characters are entered along the shortest path, an undesired input key 10 may be affected.

сначала он касается клавиши 10 ввода, которой присвоено

а затем должен совершить перемещение к клавише 10 ввода, которой присвоено

и которая расположена в диагональном направлении.For example, as shown in FIG. 8A, when the user, during a fluent entry, wishes to enter

first it touches the input key 10, which is assigned

and then must move to the input key 10, which is assigned

and which is located in a diagonal direction.

или

At this time, the portion that the finger touches during the movement is indicated by dashed lines, as illustrated in FIG. 8A. In this case, when it is determined that all of the results detected by the touch sensors 30 assigned to the input keys 10 are effective, unwanted characters may be entered, namely

or

и

, отличные от клавиш 10 ввода

и

, вводимые символы которых просто попадают на кратчайшую траекторию, участок касания других клавиш меньше, чем участок касания выбранных клавиш 10 ввода.However, since other input keys 10, such as

and

other than 10 input keys

and

, the input characters of which simply fall on the shortest path, the touch area of the other keys is smaller than the touch area of the selected input keys 10.

Therefore, as illustrated in FIG. 8A, a plurality of touch sensors 30 (dotted circles) are located in the entire input area P or on the input keys 10, so that the detected result is determined to be effective only when the number of touch sensors 21 (dashed dotted lines) for which double-touch is detected is not less than the specified amount, for example, 10.

Therefore, during fluent input, the mutual influence of the input keys 10 is prevented, so that the characters required by the user are entered correctly. Therefore, the user can correctly carry out the required input in the case in which two or more input keys 10 are selected simultaneously, if the plurality of input keys 10 are located with a high density in a narrow input area P.

Although movement is simultaneously detected on two or more input keys 10, it is automatically determined which finger is closer to the input key 10 (or which finger touches the input key 10 more). Since there are many sensors 20 available, it can be determined which input key 10 corresponds to a sensor 20 that detects a larger signal, or which center of the contact portion of which of the input keys 10 is affected.

Prevention of mutual influence when using a plurality of sensors 20 can be carried out regardless of the mutual influence between all the input keys 10 used according to the present invention, for example, the first input key 11, the second input key 12, the third input key 13, the input conversion unit 55 and the internal input key 15. The types of sensors 30 are not limited.

On the input keys 10, two or more touch sensors 30 are provided, separated from each other by a predetermined interval. The controller may determine that the selection of the input key 10 is effective only when a touch is detected by two or more touch sensors 30. Namely, referring to FIG. 8B, two touch sensors 30 are provided on the input keys 10, separated from each other from above and below or on the sides.

The controller may determine that the selection of the input key 10 is effective only when a touch is detected by all touch sensors 30 provided on the input keys 10. Therefore, when a fluent input is performed by performing a touch along the path depicted in FIG. 8B by dashed lines, since

cannot be detected by two touch sensors 30,

not an effective signal. Therefore introduced

On the other hand, in the data input device 1 according to the present invention, as illustrated in FIG. 9, the sets C of the consonant input keys and the set V of the vowel input keys are arranged in a circle on two concentric circles having different diameters.

On the other hand, a plurality of V vowel input keys may be provided on an inner column, and a set of V consonant input keys may be provided on an outer column. Conversely, a plurality of V vowel input keys may be provided on an external column, and a set of V consonant input keys may be provided on an internal column.

When the sets of consonant input keys C are provided externally, in the case in which input by touch and pressure input can be carried out separately on the input keys 10 belonging to the set of consonant input keys C, as illustrated in FIGS. 9A and 9B, 8 sets can be provided With consonant input keys. In the case in which only touch input can be performed, as illustrated in FIG. 9C, outside of the consonant input key combination C, an input conversion unit 40 may further be provided.

On the other hand, when only touch input can be performed, as illustrated in FIG. 9A, the number of vowel input key combinations V can be 8. When touch input and pressure input can be performed separately, as illustrated in FIGS. 9B and 9C , the number of sets of V vowel input keys may be 4.

Here, when the sets of V vowel input keys are integrated, the sets of V vowel input keys may perform other functions in modes other than the character input mode. For example, a plurality of V vowel input keys may perform a direction indicating function, for example, a mouse function, a mode selection function, a confirmation / cancel function, a volume control, or a scroll function.

On the other hand, as illustrated in FIGS. 9A-9C, in combination of V vowel input keys, an internal enter key 15 may be provided having one or more functions between input by touch and input by pressure.

Consonants or vowels can be provided on the internal input key 15. The internal input key 15 may be assigned commands, such as character conversion, input mode conversion, and confirmation / cancellation. In the communication input key 15 in a communication mode, a call / end function can be assigned.

On the other hand, the pressure input of the internal input key 15 can be divided into single-stage input by pressure and two-stage input by pressure depending on the pressure force.

In the cases described above, since the determination of the actual signal among the plurality of detectable signals on the sets of input keys C and V and the prevention of mutual influence between the input keys 10 has been described with reference to Fig. 8, this description will be omitted.

.Referring to the drawing, an example input in the data input device 1 according to the present invention will be described in detail as follows. First, referring to FIG. 9A, when touch, touch and pressure are continuously inputted by the first path (1),

and when pressure, touch and pressure are continuously introduced, can be entered

When pressure is continuously entered, touch (when the final signal is selected) and pressure can be entered

When the touch, touch (remaining for at least a predetermined time) and pressure are continuously entered, pressure can be entered

Therefore, in the data input device according to the present invention, the sets of consonant input keys and the set of v vowel input keys are arranged on a circle on different concentric circles, so that a consonant and a vowel or a consonant, a vowel and a consonant can be continuously entered in the shortest way.

Therefore, the input speed of characters is minimized, input can be carried out correctly, and due to the circular arrangement improves the appearance of the input device.

Here, the number of input keys 10 contained in the key combinations C and V may vary. For example, the number of input keys 10 may be 8, not less than 9, and not more than 7.

Additionally, the set of C keys for entering consonants and the set of V keys for entering vowels can be the same number, but can be of different numbers. In addition, input key combinations can contain characters of various types according to the number and types of characters in the respective countries.

и

расположены на 4 клавишах 10 ввода, принадлежащих совокупности С клавиш ввода гласных, а гласные

и

могут быть расположены на совокупности клавиш ввода согласных V.For example, when Korean characters are located on the set C of consonant input keys and the set of V vowel input keys, since the number of Korean consonants is 14 and the number of Korean vowels is 10, vowels

and

located on 4 input keys 10 belonging to the set of v input keys, and vowels

and

can be located on the set of consonant input keys V.

Here, the arrangement of the input keys provided in the present description and in the drawings is limited only in that the sets of vowel input keys are provided between the sets of consonant input keys. However, the arrangement of the consonants or vowels of the input keys contained in the combination of input keys may vary without limitation.

On the other hand, a variety of function keys other than the input key 10 described above may be further provided in the housing 110. For example, a touch function selection key 121 may be further provided for selecting an operation and stopping the touch sensors 30, so that input by touch can be selectively performed.

Additionally, there is a mode conversion key 123 for selecting a character input mode for character input by the input key 10. The touch sensors 30 operate when a mode conversion key 123 is selected for detecting input by touch.

Here, the touch function selection key 121 and the mode conversion key 123 described above prevent unwanted contact of the input keys when touch input is performed when another conventional function is performed by an electronic device such as a mobile phone. Namely, during a telephone call, the user holds both sides of the housing 110 or the input area of the housing 110 makes contact or approaches the user's face. In this case, touch input can be performed regardless of the user's intentions.

In the aforementioned case, the input of numbers can be carried out by input by pressure and input by touch.

On the other hand, as described above, the input key 10 may perform a mode conversion function, a menu selection function, a volume control function, a cursor movement function, a direction indication function or a scroll function, as well as a data input function. The scroll function is provided in the form of a mouse, so that the signals are continuous.

The above function can be implemented by detecting signals from side to side or from top to bottom. When the input keys 10 are arranged radially, the above function can be realized by means of the input keys 10 in the form of an arc.

On the other hand, another example of the present embodiment is illustrated in FIG. 34. Referring to FIG. 34, a plurality of radial second input keys 12 are provided outside the annular first input key 11. On the first input key 11, an internal input key 15 is additionally provided.

Therefore, one-step input by touch and two-step input by pressure are carried out by the first input key 11, and one-step input is performed by the second input keys 12 by touch or pressure.

In order to enter the word 'BUS' in the corresponding system, the touch starts on the first input key 11, which is assigned to 'B' and then enters 'U' by moving from the internal input key 15 to the second input key 12. Then, fluent input is continuously performed by moving to the first input key 11, where 'S' is located.

During fluent input, as described above, the selection of an effective signal is illustrated in FIG. When a quick entry is made, signals that are not canceled or saved are ignored. Therefore, without raising a finger, only the required characters can be entered, so that quick, fluent input can be performed.

The description of the one-stage and two-stage input systems on the input key 10, touch input and pressure input, the detection method, the control method implemented by the controller, fluent input and two pairs according to the first embodiment are applicable to all embodiments of the data input device according to the present invention.

Hereinafter, the above description will generally apply if no additional comments are given to the implementation options.

Second Implementation Option

In the data input device according to the second embodiment of the present invention, the input keys 10 comprise a first input key 11 and second input keys 12 located snugly inside or outside the first input key 11.

When a combination input is performed for a predetermined time, in which the first input key 11 and the second input keys 12 are selected at the same time, the controller extracts from the memory a third character, different from the character assigned to the corresponding input key 10, for inputting the third character.

As illustrated in FIG. 10, an input key 10 according to the present invention comprises first input keys 11 and second input keys 12 provided inside or outside of the first input keys 11.

The first input keys 11 may be arranged in the shape of a circle and a rectangle, as described in the first embodiment. The number of first input keys 11 is unlimited. When the first input keys 11 are arranged in a circle shape, as illustrated in FIG. 10, the second input key 12 may be provided inside or outside the first input keys 11.

On the other hand, data, including various kinds of characters, numbers and signs, can be applied to the first input keys 11 and the second input key 12. Additionally, when characters are assigned, the first input keys 11 can be arranged in a variety of ways. For example, consonants are entered by the first input keys 11 or by the second input key 12, and vowels can be entered by combinational input.

On the other hand, as illustrated in FIG. 10, the first input keys 11 and the second input key 12 can be separated from each other, however, they can occupy the same shape on the touch panel or touch screen, respectively.

The first input keys 11 comprise a one-step input for entering a first character and a two-step input for entering a second character, similarly to the first embodiment. For input by touch and input by pressure, a single-stage input and a two-stage input or a single-stage input by pressure and a two-stage input by pressure are provided.

Here, the first character, the second character, and the third to seventh characters entered by the input keys 10 using the combination input or sequential input are different. For example, the first character and the second character are consonants and the third to seventh characters are vowels.

Additionally, in the aforementioned case, the pressure input may be a multi-stage input of two or more stages.

In the case of touch input, a non-contact sensor, such as an optical sensor, an ultrasonic sensor and a non-contact electrostatic capacitance sensor, or a contact sensor, such as a contact sensor of electrostatic capacitance, can be used as touch sensors 30. The detection method used for the touch panel or touch screen can be applied under the first input keys 11 or the second input keys 12.

When introduced by means of pressure, a membrane switch can be used as a pressure sensor 40, switched by means of pressure applied by the user, or a pressure sensor for detecting pressure applied by the user.

A returning element may further be provided for returning the first input keys 11 to the initial position after pressure input is performed.

When, by means of the first input keys 11, input by touch and input by pressure are carried out, since input by touch is always detected when input by pressure is generated, when input by touch and input by pressure are detected for a predetermined time, the controller ignores the signal generated by input by touch to process only the signal generated by input by pressure.

When only input via pressure is carried out from several stages by means of the first input keys 11, multi-stage input by pressure is determined by the distance of movement of the first input keys 11 and the pressure force. At this time, in order to perform a one-stage input by means of pressure, different from a two-stage input by means of pressure, a snapping unit, such as a metal arch, may be further provided.

Further, as an effective signal selection between a single-stage input via pressure and a two-stage input via pressure, a method of selecting a signal between input by touch and input by pressure can be used.

In the data input device according to the second embodiment of the present invention, when a one-step input or a two-step input of the first input keys 11 is combined with the second input key 12, a third character is input.

Here, in a combination input between the first input key 11 and the second input key 12, for example, when input is performed by the method while simultaneously selecting the first input key 11 and the second input key 12 for a predetermined time, the controller considers the input as a new input signal, so that is input another new character other than the character assigned to the first input key 11.

11 illustrates a character arrangement of a data input apparatus according to the present invention. 11A illustrates an example of inputting Korean characters. 11B illustrates an example of a digit arrangement.

In the drawings, underlined characters are first input characters by single-step input, characters that are not underlined are second input characters by two-step input, and characters in circles are third characters entered by combination input between first input keys 11 and second keys 12 input.

A plurality of second input keys 12 may be provided so that characters can be assigned to the second input keys 12. At this time, as illustrated in FIG. 16, the first characters and second characters are displayed on the first input keys 11, the characters assigned to the second input keys 12 are displayed on the second input keys 12, and the third characters are displayed at the borders between the first input keys 11 and second input keys 12, so that the user can easily enter data.

As illustrated in the drawing, when the input data is Korean characters, consonants are assigned to the first characters and second characters or characters generated by a single input of the second input keys 12, and vowels can be assigned to the third characters. In this case, several consonants or vowels may cross other input keys 10, depending on the ability to enter the input keys 10.

11 illustrates a housing in which symbols in the form of three columns are arranged. In the case described above, the first characters and second characters entered by the first input keys 11 are preferably consonants and the third characters entered by combinational input between the first input keys 11 and the second input keys 12 are preferably vowels.

On the other hand, for entering dual consonants, additional keys for entering dual consonants (not shown) are additionally provided. Therefore, dual consonants can be entered by combining the input keys of the dual consonants and the first input keys 11 or the second input keys 12. To enter double consonants, the first input keys 11 are continuously entered twice.

In the data input device according to the present invention, for accurate input, each input key 10 may have a plurality of sensors 20 for detecting the signal of the first input key 11 or the second input key 12.

In the data input device according to the present embodiment, since the single entry of the first input key 11 and the combination input between the first input key 11 and the second input key 12 are distinguished from each other, when the selection of the second input key 12 is detected in a sensitive manner during the input signal of the first key 11 input, there is a high probability of generating input errors.

Therefore, the sensor 20 for detecting the selection of the second input key 12 consists of a plurality of detectable lines, so that the signal is determined as effective only when the signal is detected by at least a certain number of detected lines.

14 illustrates an example in which each sensor 21 of the first input keys, the sensor 22 of the second input keys, and the sensor of the third input key contains a plurality of detectable lines. 14A illustrates an example in which each sensor 21 of the first input keys, the sensor 22 of the second input keys, and the sensor of the third input key have two detectable lines. 14B illustrates an example in which each sensor 21 of the first input keys, the sensor 22 of the second input keys and the sensor of the third input key contains three detectable lines.

The number of detected lines may vary according to conditions. 15 illustrates input of a data input apparatus according to a second embodiment of the present invention. 15A illustrates signal processing of a first input key 11. 15B illustrates signal processing of a second input key 12. 15C illustrates signal processing of a third input key.

First, we describe the signal processing of the first input key 11 with reference to FIG. When the signal of the first input key 11 is detected once (refers to e1) by the sensor 21 of the first key, the data assigned to the first input key 11 is inputted once.

When portions of the detected lines of the sensor 21 of the first input keys and the sensor 22 of the second input keys are simultaneously detected (applies to e2), the controller only determines the signal of the sensor 21 of the first input keys correctly detected as effective, so that the same data is entered as the data in case when the sensor 21 of the first input keys is detected once. According to another method for preventing an input error, the controller can determine that only the option is effective when the time during which the detected signal of the first input key 11 is generated and the time during which the detected signal of the second input key 12 is generated lies within a predetermined interval.

Although the controller ignores the signal of the second input key 12 in the case in which the second input key 12 makes a quick input, so that the signals of the first input key 11 and the second input key 12 are detected for a predetermined time, the data input device according to the present invention may warn against generation when a quick entry of an erroneous input, so that the input can be carried out continuously without lifting a finger from the input key 10.

Namely, during fluent character input, at the point at which the trajectory of movement is bent, the finger lingers longer than when the finger linearly slides the detected area. Therefore, since the signal detected at the corresponding point becomes longer, only the input signal for at least a predetermined time can be determined as an effective signal.

In general, the difference between fluent input and signal holding time is generated at the position (the position where the finger touches at the beginning), at which the input starts, the position (the position at which the finger lifts at the end), at which the input stops and the position at which input is saved. The time difference can be neglected. However, the effective signal and the ignored signal can be processed by setting the time.

Therefore, the user can enter characters intended for input using fluent input by moving a finger without learning. By input processing (designated as delay time) carried out by setting the input time, scrolling functions of various electronic products or the touch panel are realized. As the touch sensors 30, an electrostatic capacitance sensor is used, so that the difference in movement and the difference in input time can be used together. As illustrated in FIG. 13, it is contemplated that the second enter key 12 is hemispherical, so that the edge of the second enter key 12 is located at the boundary between the first enter key 11 and the second enter key 12, and the second enter key 12 is only selected when the input is intentional held by the second input key 12.

Among the detected signals of the first input keys 11 and the second input keys 12 detected by the sensors 20 for inputting, the controller determines as effective only the signal that is stored for at least a predetermined time.

10 illustrates the use of an example in which a data input device according to the present invention is provided. The data input device according to the present invention can be contained in a mobile phone made thin and small, and in which it is necessary to quickly enter data.

In addition, the data input device according to the present invention can be applied to a variety of information devices, in which you must quickly enter data in the same way as in a mobile phone.

On the other hand, as illustrated in FIG. 12A, the data input device according to the second embodiment of the present invention comprises a first input key 11, second input keys 12 radially located outside the first input key 11, and third input keys 13 radially located outside the second keys 12 input.

12A illustrates that the first input key 11 is formed in a circular shape, and the second input keys 12 and the third input keys 13 are sequentially located outside the first input key 11, being integrated in a ring shape. However, the input keys, including the first input key 11, may be formed by dividing the plurality of input keys. Fig. 12B is a sectional view of the data input device illustrated in Fig. 12.

At the borders between the first enter key 11, the second enter keys 12 and the third enter keys 13, protrusions are formed so that the user distinguishes the enter keys from each other without looking at the enter keys in order to easily determine the positions of the enter keys.

FIG. 16 illustrates an example in which a first character and a second character originally assigned to the input keys 10 are inputted by a single input by the first input key 11 and the second input key 12, and the third character is inputted by combinational input by the first input key 11 and the second input key 12 .

In the case of FIG. 16, the number of first input keys 11 is 8, so that the first input keys 11 are radially located on the inner circle and the number of second input keys 12 is 8, so that the second input keys 12 are radially located outside the first input keys 11.

Assigned consonants are displayed on the first input keys 11 and second input keys 12. Vowels displayed on top of the first input keys 11 and the second input keys 12 illustrate the input of the third character by the combination input of the first input key 11 and the second input key 12.

последовательно вводятся

(однократный ввод первой клавишей ввода),

(комбинационный ввод первой клавишей 11 ввода и второй клавишей 12 ввода) и

(однократный ввод второй клавишей 12 ввода). Поэтому ввод осуществляется просто, и время, затрачиваемое на ввод, значительно сокращается.Therefore, as illustrated in FIG. 16, when Korean consonants and Korean vowels are located, a consonant, a vowel and a consonant can be entered once by performing fluent input from the first input key 11 to the second input key 12. Namely, when performing a fluent input along the path (1), for input

sequentially introduced

(single entry with the first enter key),

(combinational input by the first input key 11 and the second input key 12) and

(single entry by the second key 12 enter). Therefore, input is simple and the time spent on input is significantly reduced.

Additionally, two or more phonemes can be entered by performing a cursory entry once, in which a plurality of input keys 11 are touched in the shape of a contour.

On the other hand, in this case, the sensor 21 of the first input keys and the sensor 22 of the second input keys can have many detectable lines in the direction along the circumference and in the radial direction.

As illustrated in FIG. 16, the first input keys 11 are further provided with an internal input key 15 for assigning characters, numbers, characters, or various functions.

Here, when an internal input key 15 or a second input key 12 is provided on the first input key 11, the internal input key 15 or the second input key 12 can perform data input such as assigned symbols, numbers, and characters, a diverse functional input such as a change mode, enter key, space and cancel, and a central input function, such as combinational input by the first enter key 11, the second enter key 12 and the internal enter key 15.

Further, the central input function described above can be generally applied to all implementations in the present description.

On the other hand, the sensor 20 may have various types of detectable lines other than those described above. For example, in FIG. 17, in each of the first input keys 11 and the second input keys 12, 5 detectable lines are formed in the circumferential direction, and 3 detectable lines are formed in the radial direction, so that 15 detectable lines are provided in one input unit. However, the location and number of detected lines may vary in accordance with a system for which input keys 10 and detected lines are formed.

As illustrated in FIG. 17, when a plurality of sensors 20 are provided in a circumferential and radial direction, it is possible to determine an effective signal between the first input key 11 and the second input key 12 and determine an effective signal between the same first input keys 11.

Namely, when the signal is detected only by the sensor 22 of the second input keys (e1) and when the signal is detected on top of the two second input keys of the sensors 22, so that the detected section is shifted to one side, as the input is determined by the second input key 12 only.

Therefore, in the data input device according to the present invention, a plurality of detectable lines are provided on each input key 10. Although two or more input keys 10 are detected, the detected areas are compared with each other to determine the user's intentions, so that it is possible to quickly enter data in a narrow space.

Namely, although a plurality of high-density input keys 10 are located in a narrow region, it is possible to prevent an input error caused by a “mutual influence” between the input keys 10 using the method described above.

On the other hand, another example of the present embodiment is illustrated in FIG. Referring to FIGS. 33A and 33B, 8 first input keys 11 are provided externally, and 4 second input keys 12 are provided internally.

Characters displayed outside the arc are entered by touch input. Symbols displayed in an arc are entered by input using pressure. The characters in the box between the first input keys 11 and the second input keys 12 are entered by combinational input.

When the word 'BUS' is entered, input starts (input 'B') at the corresponding position of the first input key 11, 'U' is entered by combinational input, and returns to the first input key 11 to enter 'S'.

As described above, when, after the third character is entered only during the predetermined sequential combination, and the initial signal generated and the initial signal are generated between the first input keys 11, the first character or second character is entered only in the part in which the signal is canceled or stored , and the word can be quickly entered by performing a fluent input operation along the contour without additional character input operations.

The second input key 12 may be entered by touch or pressure, and more preferably it is provided for input by touch.

FIG. 33A illustrates an embodiment of a second input key located externally, and FIG. 33B illustrates an embodiment of a second input key 12 externally.

Even in the above-described FIG. 34, if the first character or the second character is input only when the original generated signal and the original signal are released (terminated) or stored after generation, each word can be continuously entered one after the other at a very high speed in one quick runaway input without additional action with the corresponding characters.

In the case where the first input key 11 and the second input key 12 are provided similarly to this embodiment, since there is no need to further provide for the input keys 10 to which the third characters are assigned during combinational input, the input space can be minimized with the same input capability.

Two pairs of data input device according to this embodiment of the present invention are provided on the right and left sides and on the upper and lower sides of the input space, so that the input capability can be maximized.

Third implementation option

The data input device according to the third embodiment of the present invention further comprises an input conversion unit 55 provided adjacent to the plurality of input keys 10, so that the controller extracts the fourth character from the memory and inputs the fourth character as a result of sequential input in which the input keys 10 and the block are sequentially selected 55 input conversion.

Consonants can be entered by single entries of the corresponding input keys 10 and vowels can be entered by sequential entries depending on the order of the input keys 10 and the input conversion unit 55.

In this case, no input can be made by sequential input in the reverse order. Alternatively, vowels may be entered by sequential input depending on the order of the input conversion unit 55 and the input key 10. Even in this case, no input is performed by sequential input in the reverse order.

The plurality of input keys 10 can be arranged in a circle shape, so that the controller can reliably retrieve and enter only the character assigned to the input key 10, which is ultimately selected during circle input, when the plurality of input keys 10 are sequentially selected in the circumferential direction .

Alternatively, the input conversion unit 55 provided in the center of the circle corresponding to the inside of the input keys 10 may further be included. In this case, the controller can retrieve and enter the fourth character when the internal sequential input is performed by selecting the keys in the order: the first input keys 11 and the input conversion unit 55, or the external serial input by selecting the keys in the reverse order.

In the respective cases described above, the direction of sequential input for inputting the assigned vowel can be marked on any input key 10 or input conversion unit 55. Here, in accordance with the input zone, two pairs of input keys 10 or an input conversion unit 55 can be provided.

In the respective cases described above, the direction of sequential input for inputting the assigned vowel can be marked on any input key 10 or input conversion unit 55. Here, in accordance with the input zone, two pairs of input keys 10 or an input conversion unit 55 can be provided.

Next, a data input device according to a third embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Corresponding input keys 10, like the embodiments described above, are provided in such a way that one-step input for inputting the first character and two-step input for entering the second character are performed independently.

Single-stage input and two-stage input can be carried out by input by touch and input by pressure, or only multiple inputs by pressure. Moreover, in appropriate cases, the pressure inputs can be more than two-stage (or three-stage).

Referring to FIG. 18, eight input keys 10 of a number are radially located in the input zone P, and each input keys 10 can protrude to a height equal to or similar to the height of the housing 110 to allow fluent entry. In this case, the plurality of input keys 10 may not be formed by the individual components of the integrated ring type input key.

In the case of an integrated ring type input key 10, like eight input keys, the input keys 10 implement a pressure direction function in eight radial directions like eight input keys.

Additionally, of course, the ring type input keys 10 have a circular shape and a polygonal shape.

Each input key 10 may be assigned two or more duplicated first characters. This is more effective for the case of multiple phonemes, as in Japanese characters.

In other words, when eight input keys 10 are provided, since the sixteen first characters are respectively assigned to single-step input and two-step input of input keys, and eight fourth characters are assigned to the sequential input of input keys 10 and input conversion unit 55, a total of 24 characters can be assigned.

Therefore, in Korean characters, each phoneme can be located without adding the number of 10 input keys and multi-stage input. In the case of a very large number of phonemes, such as alphabets, Japanese characters, or Chinese characters, the ability to enter can be enhanced by a variety of ways to add input keys 10, multi-stage input, or by ensuring their presence in two pairs.

Here, when entering characters, consonants are assigned to the first characters and vowels are assigned to the fourth characters.

This is intended to arrange the consonants on the input keys 10 for a relatively free increase in the possibility of input, and to provide vowels for sequential input, since in each language the number of vowels is less than the number of consonants.

An input conversion unit 55 may be provided in a variety of positions and shapes, for example, as illustrated in FIG. 18, inside or outside the input keys 10 on a round plate or in the shape of a ring.

FIG. 18A illustrates an input conversion unit 55 provided inside the input keys 10 on the round plate, and FIG. 18B illustrates an input conversion unit 55 provided outside the integrated ring type input keys 10.

Fig. 19 illustrates another embodiment of a data input device according to the present invention, in which the input keys 10 are arranged in a rectangle shape.

As illustrated, each of the input keys 10 contains two columns of the corresponding four input keys.

An input conversion unit 55 may be located in the center of the input keys 10, as illustrated in FIG. 19A, or on both sides of the input keys 10, as illustrated in FIG. 19B. Here, in the data input device, as illustrated in FIG. 19, the number of input keys 10 and the number of locations of the input keys 10 can be changed in a variety of ways. Input of the input conversion unit 55 can be carried out in various ways, such as touch input, pressure input and touch / pressure input, so that functions such as a separate input or an individual mode change can be performed, and can be used as an enter key a mobile phone with a call / end function or the enter / confirm key.

Alternatively, the input conversion unit 55 may perform a mode change, a menu selection function, a volume control function, a cursor move function, a direction indication function, or a scroll function like the input keys 10.

FIG. 20 is a perspective view illustrating another data input device according to a third embodiment of the present invention. As illustrated in the drawing, the input key 10 may comprise first input keys 11 and a third input key 13.

The third input key 13 may enter data through a combined operation of the first input keys 11 and the input conversion unit 55, and in contrast to FIG. 20, additional individual keys such as a key are provided for performing frequently performed functions near the first input keys 11 or the input conversion unit 55 mobile phone call / end call.

Alternatively, a third input key may be generated so that the first character is inputted by touching the first input keys 11 and the fourth character is inputted by sequentially inputting the first input keys 11 and input conversion unit 55, and a new character can be inputted by sequential first the input keys 11 and the third input key 13.

An input conversion unit 55 may be formed so that a character can be entered by a sequential operation as such and an input key 10. In particular, in the case where a third input key 13 is additionally provided, since a plurality of characters, signs and numbers can be entered without changing the modes, it is possible to enter more quickly.

If the third input key 13 is located near the input keys 10 and the input conversion unit 55 for inputting data depending on the operations of the input keys 10 and the input conversion unit 55, the third input key 13 can be made of various types other than those illustrated in FIGS. 18-20 .

Two or more duplicated first characters can be assigned to the input keys 10, so that consonants are assigned to the first characters and vowels are assigned to the fourth characters.

Although the consonants and vowels are located in the opposite way compared to those described above according to the input characters, it is preferable to enter one of the vowels and consonants, with a large number and more often, using the input keys 10, and the rest are entered by sequentially entering the input keys 10 and the block 55 input conversion.

In addition, symbols may be arranged in a different manner, as described above, and various numbers, signs, commands, and symbols may be arranged.

Furthermore, if it is difficult to arrange all the characters in the input key system 10 illustrated in FIG. 21, it can provide touch input or pressure input to the input conversion unit 55.

21 illustrates a character arrangement in a data input unit according to this embodiment of the present invention, in particular a detailed arrangement of Korean characters, alphabets, and numbers, respectively.

In the case of alphabets, as illustrated in FIG. 21B, when eight input keys 10 are provided, sixteen characters are assigned for one-step input and two-step input, eight characters are assigned for sequential input of the input keys 10 and input conversion unit 55, and the remaining two characters are assigned to block 55 transforming input in the form of input by touching and input by pressure.

Alternatively, if the input conversion unit 55 implements the function of either input by touching or input by pressure, a method of pressing a key in sequence twice is used to convert a character, with an additional input key provided on the inside or outside of the input keys 10 and the input conversion unit, or right and on the left or upper and lower sides of the input conversion unit 55, touch input, pressure input, or tilt function are provided.

и

In the case of Korean characters, an additional key can be assigned

and

In the aforementioned case, the detection function for inputting the fourth character by the sequential combination of the input keys 10 and the input conversion unit 55, like the initial function of the input conversion unit 55, is located in the center, and the center may have an additional distinguishable signal.

In this case, the central distinguishable signal is inputted by successively touching twice or is performed by inputting by touching and inputting by pressure. The input conversion unit 55, depending on the input operations described above, can be used in telephone mode for functions such as changing the mode, confirming, canceling, and making / ending a call.

Alternatively, in telephone mode, the directional input function of the input conversion unit 55 can be used as a function, such as changing a mode, confirming, canceling, and calling / ending a call.

Moreover, the input conversion unit 55 implements directional movement or directional pressure, so that the input conversion unit 55 can be used as a mouse or joystick for games.

Serial input is used to enter the fourth character depending on the sequential selection of the input keys 10 and the input conversion unit 55. Serial input can be formed so that a different signal can be input depending on the sequence of input keys 10 and input conversion unit 55, or a single identical signal can be input.

In the latter case, sequential input can use both types or any one selectively. In other words, only sequential input in the order of input keys 10 and input conversion unit 55 (Fig. 22A) is valid, and serial input in reverse order (Fig. 22B) cannot enter any data.

On the other hand, in the data input apparatus according to this embodiment of the present invention, fluent input is provided.

. В этом случае среди множества детектируемых сигналов действительными являются только первоначальный детектируемый сигнал и конечный детектируемый сигнал.As illustrated in FIG. 23, the possibility of fluent input enables movement along a circle. It serves to continuously select two or more input keys 10 for inputting continuous consonants, such as

. In this case, among the plurality of detected signals, only the initial detected signal and the final detected signal are valid.

Here, in the method for determining the final detected signal, the final detected signal is determined, for example, by continuously generating a plurality of detected signals, when the signals are continuously generated without any break point even for any one signal, and the signals are interrupted, or when two or more fluent inputs are continuously detected during the corresponding specified time intervals, and after the specified time intervals expire for a given detected signal, the next signal is not not irrelevant.

24 illustrates sequential input according to the present invention.

Символ, присвоенный верхней стороне соответствующих клавиш 10 ввода, является первым символом, вводимым путем ввода посредством касания, символ, присвоенный центру, является первым символом, вводимым путем ввода посредством давления, а символ, присвоенный нижней стороне, является четвертым символом, вводимым посредством последовательного ввода.Figa illustrates the location of Korean characters, in which eight input keys 10 are arranged in two columns, and additionally provides an additional key 10A to indicate

. The character assigned to the top side of the corresponding input keys 10 is the first character entered by input by touch, the character assigned to the center is the first character typed by pressure, and the character assigned to the bottom is the fourth character typed in .

В этом случае последовательный ввод выполняется только посредством последовательного касания от блока 55 преобразования ввода до клавиши 10с ввода, и пренебрегается последовательным вводом, выполняющимся посредством последовательного касания от клавиши 10b ввода до блока 55 преобразования ввода.The line in FIG. 24A is a line indicating finger movement for entering a Korean character

so that for input, the input key 10 corresponding to the first character is touched

is inputted by sequentially inputting the input conversion unit 55 and the input key 10, and touch is performed

for input using fluent input. In this case, the sequential input is performed only by sequentially touching from the input conversion unit 55 to the input key 10c, and the sequential input performed by sequentially touching from the input key 10b to the input conversion unit 55 is neglected.

On the other hand, fluent input from the input key 10c to the key 10d is applied in a method where only the final signal is valid.

the input key 10f assigned to the third character is touched

and continuously touches the input conversion unit 55 for input

so input

In this case, the sequential input from the input key 10j to the input conversion unit 55 is neglected, and the single input of the input key 10i is sequentially neglected for sequential input from the input conversion unit 55 to the input key 10i.

, соответствующего первому символу, выполняется последовательный ввод от клавиши 10j ввода до блока 55 преобразования ввода для ввода

.On the other hand, figv illustrates the movement performed by the user to enter

As illustrated, the input key 10h is touched to enter

corresponding to the first character, sequential input is performed from the input key 10j to the input conversion unit 55 for input

by input by touch, and the input key 10i is touched to enter

.

Here, when two or more input keys are continuously inputted, an input between the respective input keys from among the input keys 10 can be formed to input the initial input signal and the final input signal.

25C and 25D illustrate an example of inputting alphabets.

First, referring to FIG. 25C, (1) indicates a fluent input path for entering the English word 'RASER', and (2) indicates a fluent input path for entering the English word 'THE'.

The method for determining the final input signal is identical to that described above. When a finger is released from an input key for final input during a fluent input (fluent input), a character inputted by input by touch is inputted and a character inputted by input by pressure is inputted when the finger is released after input by pressure.

Due to this, the user simultaneously enters consonants and vowels (without an additional input operation) and can enter other characters by fluent input within the input keys, so that the user can enter the character by operation in one step without individually touching or pressing the corresponding input keys.

In other words, when a consonant - a vowel - a consonant is entered sequentially, the user selects a consonant for input from among the input keys 10 for input by touch or input by pressure, in second place - a vowel for input by touching the input keys 10 through the input conversion unit 55 (input by touching), and a third is a consonant for input by input keys 10 by input by touch or input by pressure.

In this case, although the third consonant can be entered through an individual operation after the second vowel, it is preferable to introduce the third consonant continuously by fluent input simultaneously with the second vowel, as described above.

In other words, in the input method according to the present invention, input can be performed not by means of individual input consonant - vowel or consonant - vowel - consonant, but by fluent input in one step.

Most languages consist of consonants and vowels, most words consist of a consonant - vowel or consonant - vowel - consonant, a single word has an average of 4.7 phonemes.

Therefore, when characters are inputted using the input method of the present invention, a single character for a single word can be entered very quickly and conveniently by a fluent input operation in one go. In addition to the consonant - vowel and consonant - vowel - consonant as described above, words can be entered in the form of a consonant - consonant - vowel, vowel - vowel - consonant, vowel - consonant - vowel and vowel - consonant - consonant.

In the respective embodiments described above, as illustrated in FIGS. 24 and 25, both the input conversion unit 55 and the input keys 10 can be marked with an arrow indicating the direction of the sequential input.

Fourth Embodiment

A data input device according to a fourth embodiment of the present invention comprises a plurality of input keys 10 arranged in a circle in which corresponding input keys 10 are assigned to duplicate fifth characters, so that the controller extracts fifth characters from the input memory when buffered input is detected.

Buffered input can be of various types, for example, an operation where a finger is released from a predetermined input key 10 during a fluent input to release a detected touch signal. In other words, it is called by releasing the signal on the input key 10, for example, it can be distinguished by the difference between the detected time, the detected currents, or the detected presses.

Referring to FIG. 26, buffered input using a signal freeing method will be described. The first character assigned to the corresponding input key is entered when the user touches part of the input keys 10, and buffered input is determined when the input continues while the plurality of input keys 10 scroll in the circumferential direction and the finger is released to release the signal, so that instead of the first character assigned to the corresponding position, the fifth character is entered.

In a buffered input, depending on the different detected time, when the first character is entered in position A1, a fluent input is performed through position A2, and in position A3, signal detection continues for a longer time than the specified time, the controller determines this as input buffered to enter the fifth character assigned to position A3.

It goes without saying that if the detected time at position A2 is less than a predetermined time, the first character assigned to position A2 is entered instead of the fifth character.

Buffered entry, depending on the difference in the detected time, can be performed at the intermediate step of runaway input, for example, when during runaway input from position A1 to position A3, the finger is held in position A2 for a longer time than the specified time, the fifth character is entered, assigned to position A2.

Therefore, in this case, the first character assigned to position A1, the fifth character assigned to position A2, and the first character assigned to position A3 are sequentially entered.

Buffered input can be processed using several different signals, other than a hold or release signal, such as pressure, static capacitance, etc.

Alternatively, buffered input may be performed by pressing the side surface of the input keys in a direction transverse to the directions of pressing the input keys 10. Alternatively, buffered input can be made by changing the fluent input direction by using the corresponding input keys 10. In other words, a tap or a fluent input in the circumferential direction of the respective input keys 10 is a single entry, and a fluent input in the radial direction is a buffered input.

In this case, the touch sensor 30 comprises a first touch sensor 30 a for detecting touches or fluent input in the circumferential direction of the respective input keys 10 and a second touch sensor 30 b for detecting fluent input in the radial direction of the respective input keys 10.

Alternatively, the buffered input may be formed such that a vowel is inserted and then a consonant is entered when the buffered input is generated during a tap moving in a circumferential direction.

On the other hand, during buffered input, in order to enter a consonant and a vowel that are duplicate assigned to a given input key 10, a method of storing a touch on the corresponding input key 10 for a predetermined time is used.

присвоенного клавише 10 ввода в качестве первого символа посредством касания, и присвоения

в качестве пятого символа для ввода с буферизацией, поскольку

не может вводиться посредством беглого ввода на идентичной клавише 10 ввода, первоначально выполняется касание соответствующей клавиши 10 ввода для ввода

, и состояние касания сохраняется в течение заданного времени для дополнительного ввода

, так что символ

может быть введен.For example, in the case of assignment

assigned to the input key 10 as the first character by touching, and assigning

as the fifth character for buffered input since

cannot be entered by fluent input on an identical input key 10, initially the corresponding input key 10 is touched to enter

, and the touch state is stored for a specified time for additional input

so the symbol

can be entered.

The input keys 10, as illustrated in FIGS. 26-28, comprise a first input key 11 arranged in a circle shape and a second input key 12 adjacent either inside or outside the first input key 11.

Referring to FIG. 26, a second input key 12 is provided inside the first input key 11 in the form of an integrated ring.

The first input key 11 comprises a rotatable device, such as a bearing, rotatably disposed in a circumferential direction from a lower side.

27 illustrates a plurality of individually provided first input keys 11 arranged in a circle shape. In this case, as illustrated in FIG. 27B, the corresponding first input keys 11 can be individually selected, so that the user more easily feels an exact click, compared to the integrated type.

On the other hand, the first input keys 11 can be arranged in a variety of ways, for example, as illustrated in FIGS. 26 and 27, in the shape of a circle, and, as illustrated in FIG. 28, in the shape of a polygon. The first input keys 11 may also be arranged in a rectangle shape, similarly to the embodiment described above.

On the other hand, in the case where the first input keys 11 are arranged in a circle or polygon shape, depending on the signal detected in the circumferential direction, the first input keys 11 may perform a function, such as mouse scrolling or volume control.

A second input key 12, as illustrated in FIGS. 26-28, may be provided inside the first input keys 11 on a round plate or outside of the first ring-shaped input keys 11.

The first input keys 11 and the second input key 12 can be provided in a variety of shapes and for various layouts other than the above described embodiments, without any limitation.

The controller may retrieve a third character from the input memory different from the character originally assigned to the corresponding input key 10 when combining input is performed while simultaneously selecting the first input keys 11 and the second input key 12 within a predetermined time.

29 is a sectional view illustrating a data input device according to this embodiment of the present invention. Referring to FIG. 29, the first ring-shaped input keys 11 are provided externally, the second round-shaped input key 12 is provided inside the first input keys 11, and a sensor 21 of the first input keys 21 is provided on the lower sides of the first input keys to detect input by pressure . Here, a touch sensor 30 may further be provided for detecting input by touching on the first input keys 11.

The first input keys 11 and the second input key 12, as described above, are provided for independently performing single-stage input and two-stage input, so that one-stage is touch input and two-stage is pressure input, or both single-stage and two-stage input are inputs through pressure.

When the second input key 12, as illustrated in FIGS. 26-29, is provided inside the first input keys 11 on the round plate, the center and the edge of the second input key 12 distinguish and detect two signals.

It is envisaged that the second input key 12 performs input by touch / input by pressure or single-stage input by pressure / two-stage input by pressure in the radial direction (preferably in four or eight directions).

Depending on the size of the first input keys 11 and circumstances of use, input other than four directions, east, west, south and north, input by touch / input by pressure or single-stage input by pressure / two-stage input by pressure can be added.

The second input key 12 can carry out the function of the touch panel or the function of the touch screen, provide horizontal movement in the radial direction, and perform the function of the mouse through the touch panel or horizontal movement. In this case, the functions of the right and left mouse buttons can be implemented by input from the edge. Alternatively, a handwritten character reading function may be implemented using the second input key 12.

The functions described above are not limited to this implementation option, but can be applied to other implementation options without limitation.

Even in the case where the second input key 12 is provided in the form of a ring outside the first input keys 11, the possibility of one-step input and two-step input is provided.

Symbols, numbers, signs or various functional commands are assigned to single-step input and two-step input, for example, in the case of Korean characters, can be assigned

In contrast, the second input key 12 can change the mode and move the cursor when entering characters. Alternatively, as illustrated in FIG. 30, depending on the directional movement of the second input key 12, the mouse pointer moves, numbers or characters are entered, various command keys can be entered, such as various mode changes, enter key, space bar, key cancel and move the cursor.

In this case, a motion sensor (not shown) is additionally provided for detecting the radial movement of the second input key 12, and the input controller extracts the sixth character from the memory assigned to the corresponding radial direction in which the movement of the second input key 12 is detected.

Although the second enter key does not move, according to the direction of the touch move, the sixth character assigned to the touch move by the second enter key 12 can be entered. In this case, a touch sensor 30 should be provided to detect the direction of movement of the touch.

FIG. 31 illustrates an arrangement of Korean characters, English characters, and buffering numbers of a data input apparatus according to this embodiment of the present invention. First of all, in the case of Korean characters, as illustrated in FIG. 31A, consonants (first characters) in large numbers and often used in duplicate are assigned to the first input keys 11, and vowels (fifth characters) entered by buffered input are marked on circles.
