Description

Character input device and its method {CHARACTER INPUT DEVICE AND ITS METHOD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character input device and a method thereof, and in particular, by allowing the first direction input and the second direction input to be simultaneously or sequentially performed in one input unit, the number of characters that can be input in one operation in a minimum input space. The present invention relates to a character input device and a method thereof capable of maximizing and simultaneously inputting one or more phonemes in one operation.

Recently, with the development of software, semiconductor technology, and information processing technology, information devices are becoming smaller and smaller, and the input of characters in various information devices is also increasingly important.

However, many problems have been revealed in the input of various characters or commands in such information devices.

For example, an input device such as a keyboard used in a personal computer (PC) or a notebook (NoteBook) has a limitation in reducing its size, which makes it difficult to miniaturize these information devices.

In addition, a touch screen method used in a PDA (Personal Data Assistant) or a keypad method used in a mobile phone is inconvenient because of a low input speed and a lot of wrong input.

In order to input letters, numbers or symbols at a higher speed in the above-described information devices such as PCs, laptops, PDAs or mobile phones, so-called 1 operation 1 phoneme input is performed in which one phoneme (character) is input in one input operation. There is a need.

In the case where the operation 1 phoneme input is for Korean, the buttons or input keys for inputting 24 or more characters need to be arranged in the information apparatus.

If the target language is English, Japanese, or other foreign languages, more buttons or input keys may need to be added than in Korean.

In addition, as the performance of the desktop PC is increasingly realized in the portable terminal, the portable terminal must be able to perform all input functions of the keyboard, such as various command keys (enter, space, shift key, etc.), Fzl, and symbols, as well as character input. The situation is reaching.

However, the conventional input device used in various information devices is a method of assigning a letter to each input key and tapping or pressing with a finger.

Therefore, in a personal portable information terminal such as a mobile phone having a relatively small space for arranging input keys, it is difficult to arrange more than 24 input keys of a finger size. This has been the reason why keyboards have never been miniaturized so far.

Particularly, in the case of a mobile phone, it is inevitable that a plurality of characters are repeatedly arranged in one button since all Korean characters are inputted with 24 or more characters with 12 buttons.

Therefore, the repeated input phenomenon of repeatedly inputting twice and three times to input one character (phoneme) occurs frequently, so that the input time is long and there are a lot of typos.

In addition, the input method itself is very complicated and takes a long time to get used to it.

In order to solve this problem, a character input method for inputting a combination of predetermined characters, such as 'Cheonjiin', has been proposed.

However, the above-mentioned method has the advantage of reducing the number of input buttons for allocating characters because the desired characters are generated by combining the basic characters, but the input buttons must be repeatedly pressed until the desired characters are combined. As a result, the input time was longer.

In addition, technologies such as a keyboard that can be rolled around or a virtual laser keyboard that detects the position of a finger and inputs it when a user performs an operation such as projecting an image of the keyboard keyboard on the floor and inputting the keyboard with a finger thereon are also used. It has been proposed.

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

Accordingly, an object of the present invention is to provide a new input unit in which the first direction input and the second direction input are performed separately or in combination, thereby minimizing the space required for the input of characters and the like, and all the desired characters in one input operation. By inputting quickly and accurately, and by maximizing the number of keyboards that can be arranged in a given space through the multi-stage input function and the configuration of bees, all the input functions of the keyboard keyboard and the mouse input function used in the desktop PC can be quickly and quickly used in the portable terminal.

First direction input (M)

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

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

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

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

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

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

Here, the first direction input position (M ₁ , M ₂ , ...) is to be provided in various numbers as necessary, the first direction input (M) may be performed a variety of methods, for example, the input unit 10 Can be performed from the state positioned at the reference position S (see (a) of FIG. 4) toward the first predetermined direction indication position M ₅ (or horizontal movement, see (b) of FIG. 4). have.

delete

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

In this case, when the input unit 10 performs the first direction input M, the input unit 10 may move radially around the reference position S, as shown in FIG. 5C. It may also be performed while sliding in the circumferential direction about the reference position (S) within the radius (111).

5 is for inputting the 'high' in the Hangul character input, the input unit 10 is the first direction indicating position (M ₁ , M ₂ , ... After sliding toward (see (b) of FIG. 5), it moves in the circumferential direction and inputs 't' (see (c) of FIG. 5).

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

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

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

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

That is, after the input unit 10 is moved in the circumferential direction to generate a plurality of detection signals belonging to the first direction input M, the center input C or the second is successively (that is, without returning to the reference position S). When generating a different type of detection signal by performing the two-way input P, only the first direction input M immediately before switching to the center input C or the second direction input P is effectively input. .

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

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

Here, as shown in FIG. 4, a support part 25 provided between the input part 10 and the base 110 to support the movement of the input part 10 may be further provided.

On the other hand, the first direction input (M) is inclined toward any one of the first direction indicating position (M ₁ , M ₂ , ...) as shown in (b) of FIG. It can also be done.

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

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

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

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

The guide part 40 allows the user to move in the correct direction intended by the user when the input part 10 moves, thereby allowing accurate input to be made without interference in the first direction input M. FIG.

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

Alternatively, as shown in FIG. 2, a disk-shaped groove corresponding to the input radius 111 is formed in the base 110 to limit the moving distance in the radial direction of the input unit 10 and at the same time the input unit 10. Can guide the movement in the circumferential direction.

Alternatively, as shown in FIG. 9, it may be provided as a concave groove corresponding to each of the first direction indicating positions M ₁ , M ₂ ,.

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

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

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

That is, when the first direction input M is performed through the horizontal movement (or sliding) of the input unit 10 as shown in FIG. 3, each first direction instruction position M from the reference position S is obtained. Two or more first sensing units 61 may be sequentially provided on a movement path of the input unit 10 facing ₁ , M ₂ ,.

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

6 and 7 (c), the relatively long first contact portion 27a and the relatively short second contact portion 27b along the edge of the elastic member 21 provided below the input portion 10 are provided. The first sensing parts 61a and 61b may be provided on one side of the base 110 corresponding to the contact parts 27a and 27b.

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

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

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

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

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

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

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

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

Alternatively, whether the first stage input is released instead of whether the predetermined time has elapsed (for example, whether the first stage input M is performed and then returned to the reference position S, or the first stage input detection signal is It is also possible to determine whether or not the first stage input is changed according to the case of turning off.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The input unit 10 may be provided in various shapes.

For example, as shown in FIG. 2, a disc shape may be provided, or a polygonal plate shape may be provided, and as shown in FIG. 9, each first direction indication position M ₁ , M ₂ , It may be provided in a shape in which the side protrudes in the ...) direction.

Alternatively, as shown in (c) of FIG. 9, the second direction indicating positions P ₁ , P ₂ ,... May be provided in a cross shape.

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

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

There is no limitation on the moving radius of the input unit 10 during the first direction input M. Preferably, as shown in FIG. 25, the movement within the moving radius of the finger placed on the input unit 10 on the input unit 10 is not limited. It can be arranged to be possible.

As illustrated in (a) of FIG. 11, the upper surface of the input unit 10 may include a non-slip 54 to prevent a finger contacting the input unit 10 during the first direction input M from slipping. .

The non-slip unit 54 may be provided in various kinds, for example, may form irregularities on the upper surface of the input unit 10, or may form a concave groove in the center of the input unit 10.

Alternatively, both of the above may be provided.

Alternatively, as illustrated in (b) or (c) of FIG. 11, the input unit 10 has protrusions 52b and 52c provided at one side of the upper end to facilitate gripping and manipulation of the finger during the second direction input P. May be

On the other hand, as shown in (d) of FIG. 11, the input unit 10 protrudes from the center of the upper surface to smoothly manipulate the input unit 10 when the first direction input M or the second direction input P is performed. It may further include a protrusion 53 for letting.

The protrusion 53 is intended to facilitate input even when using the character input device 1 according to the present invention on a table or the ground, when using not only a thumb but also a finger such as an index finger or a middle finger.

The protrusion 53 may be provided in various shapes. For example, as shown in FIG. 11D, the protrusion 53 may be provided in a ring shape, or may be provided in a convex or concave shape.

On the other hand, the one end is inserted into the protruding portion 53 may further include a manipulation bar (56). The protrusion 53 may be provided at an upper end of the input unit 10 as shown in FIG. 11D, and the operating rod 56 is provided at the upper end of the input unit by providing a coupling part 57 into which the operating rod is inserted. It is also possible to operate the input unit 10 while being inserted into 53).

Second direction input (P)

In the present specification, the second direction input P is selected by selecting one of the plurality of second direction indication positions P ₁ , P ₂ , .. radially spaced apart from the input unit 10. The second character assigned to the two-way instruction position (P ₁ , P ₂ , ..) shall be entered.

That is, the first direction input M moves toward the first direction indication positions M ₁ , M ₂ ,..., Disposed outside the input unit 10 while the input unit 10 and the support unit 25 are all moved. On the other hand, the second direction input P selects the second direction indication positions P ₁ , P ₂ ,... Arranged on the input unit 10, so that the entire horizontal portion of the input unit 10 and the support unit 25 is performed. No movement (or sliding) or tilting is performed.

The second direction input P may be performed in various ways. For example, as illustrated in (c) of FIG. 4, only the input unit 10 may have the second direction indication positions P ₁ , P ₂ , and the like. It may be performed by tilting toward any one of the (..) of course, even if only the input unit 10 is tilted, the support 25 may be slightly moved, but the movement of the support is insignificant.

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

Alternatively, as shown in FIG. 5, the second direction input P may include any one of the pressing parts 11 provided in the input unit 10 corresponding to the second direction indicating positions P ₁ , P ₂ ,... It may also be done by selecting one.

Here, the pressing unit 11 includes all forms (except tilting of the input unit 10) that can independently select each of the second direction indicating positions P ₁ , P ₂ , .. on the input unit 10. do.

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

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

Similarly, even when the second direction input P is performed by tilting the input unit 10, as shown in FIG. 11B, a finger is touched while one finger contacts the input unit 10. It is preferable that the inclined input unit 10 be tilted to the second direction indicating positions P ₁ , P ₂ ,...

The second sensing unit 63 may be provided in various ways according to the form in which the second direction input P is performed.

For example, when the second direction input P is performed by tilting the input unit 10, a step of sequentially contacting the base 110 according to the tilt of the input unit 10 at the lower edge of the input unit 10 is performed. It may be provided as a contact sensor for detecting the contact of the input unit 10 and the base 110 in the step or the base 110, or may be provided as an optical sensor for detecting the inclination of the input unit 10.

Alternatively, when the second direction input P is performed by each pressing unit 11 provided in the input unit 10, the second direction input P may be provided as a contact sensor, a push switch, a pressure sensor, or the like provided below the pressing unit 11. Can be.

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

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

Referring to FIG. 4E, when the second direction input P is provided in two stages, for example, a step is formed along the lower edge of the input unit 10, and the first stage is inclined by one stage. The lower second sensing unit 63a may be in contact with the base 110, and the second sensing unit 63b may be in contact with the base 110 by tilting the second stage.

Alternatively, as shown in (a) of FIG. 7, the elastic member 21 or the input unit 10 provided below the input unit 10 protrudes to different lengths toward the second sensing units 63a and 63b. The third contact portion 27c or the fourth contact portion 27d can be provided.

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

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

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

For example, in FIG. 8, the letter 'A' is input by contact with a predetermined second direction indicating position P ₂ , and the letter 'B' is tilted by the tilting toward the second direction indicating position P2. It is input.

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

Here, the first direction indicating position (M ₁ , M ₂ , ...) and the second direction indicating position (P ₁ , P ₂ , ..) may be provided in various numbers, for example, 4 to 12 It may be provided in any one of the directions.

Here, it is preferable that the first direction indicating position (M ₁ , M ₂ , ...) and the second direction indicating position (P ₁ , P ₂ , ..) be provided with 8 or less, which is a human finger. This is because when the number of input directions that can be operated exceeds eight, the distance between the direction indication positions becomes narrow, which may lower the input accuracy.

In this case, with respect to the number of insufficient direction indicating positions, by combining the central input (C) described later, or by providing the input unit 10 in two left and right directions, it is possible to implement the optimum input conditions while arranging all the characters necessary for input. .

Also, the first direction indicating positions M ₁ , M ₂ ,... And the second direction indicating positions P ₁ , P ₂ , .. may be provided in the same number or in different numbers. .

Meanwhile, as shown in FIG. 10A, the second direction input P is provided with contact portions 27c and 27d at the lower portion of the input portion 10 and presses the pressing portion 11 to press the second sensing portion ( 63).

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

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

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

6 and 7 show a character input device 1 according to a second embodiment of the present invention. Referring to the drawings, the first direction input M is performed while the input unit 10 slides from the reference position S toward the first direction indication positions M ₁ , M ₂ ,..., And the second direction. The input P is performed while the input unit 10 is inclined toward one of the second direction indicating positions P ₁ , P ₂ , .. from the horizontal position.

As shown in FIG. 7C, the first direction input M includes contact portions 27a and 27b protruding along the edge of the input unit 10 or the elastic member 21 and the base 110 corresponding thereto. ) By the first sensing units 61a and 61b.

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

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

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

Meanwhile, referring to FIG. 7B, a return member 58 is provided below the input unit 10 to return the input unit 10 to its original position after the second direction input P is performed.

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

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

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

10 (c) shows another embodiment of the present embodiment.

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

At this time, the inner surface of the elastic member 40 is provided with contact portions (27a to 27f) protruding with different lengths toward the sensing unit (61, 63, 65) can perform a multi-stage input.

A conductive member 23 is interposed between the contact portions 27a and 27b and the elastic member 40, one end of the conductive member 43 is connected to the ground terminal 64, and the other end thereof is the contact portion 27a to 27f. Is connected to, the detection signal is transmitted to the control unit 60 through the contact portion (27a to 27f).

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

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

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

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

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

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

Here, although not the aforementioned 'tilt movement', as shown in FIG. 8, the first direction input M is performed by sliding, and the second direction input P is also performed by tilting the input unit 10. May be

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

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

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

10B shows a character input device 1 according to the fourth embodiment of the present invention.

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

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

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

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

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

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

For example, the first direction input M may be provided as a first stage input, and the second direction input P may be provided as a two stage input. In this case, the consonant letters may be input by the second direction input P, and the vowels may be input by the first direction input P.

This is because the number of consonants is higher in number and frequency of use than most vowels in most national characters, and the second direction input P may be easier than the first direction input M when inputting multiple stages. Because there is.

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

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

Furthermore, since the first direction input M and the second direction input P have no constraint between each input operation (that is, to perform one input operation necessarily another input operation, etc.), a plurality of inputs are provided. By performing the operations in succession, they can be performed as if they were a single input operation.

For example, referring to FIG. 25, an input example of the character input apparatus 1 according to the present invention will be described. When an alphabetic character 'CAR' is to be input, the second direction indicating position to which the consonant 'C' is assigned ( After tilting the input unit 10 (or selecting the pressing unit 11) toward P ₇ ), the input unit 10 is moved toward the first direction indicating position M ₁ to which the vowel 'A' is assigned. Next, the input unit 10 may be inclined again toward the second direction indicating position P ₂ to which the consonant 'R' is assigned. Here, the three operations described above may be performed sequentially with the same or slight difference, so that a word composed of a plurality of letters may be input like a continuous operation.

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

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

Each configuration to be described later can be applied alone as well as two or more may be applied at the same time, in this case it is noted that various combinations are possible.

Center input (C)

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

For example, as shown in FIG. 3, the central input C may include a central input key 13 selectable at the center of the input unit 10 and a third sensing unit sensing selection of the central input key 13. 65 may be performed.

Alternatively, as shown in (d) of FIG. 4, the central input C is provided such that the entire input unit 10 is movable up and down with respect to the base 110, and the input unit 10 or the base 110 is moved. Any one of the above may detect the vertical movement of the input unit 10.

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

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

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

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

Here, when the central touch detection unit 61a is provided, the control unit 51 ignores the detection result of the touch detection unit 67 when the contact of the finger is detected by the central input key detection unit 69 for a predetermined time or more. The touch input may not be performed.

Center combination input CM , CP )

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

For example, when performing the first direction input M as shown in FIG. 4B, while the center input key 13 shown in FIG. 3 is pressed, the input unit 10 is moved to a predetermined first direction indication position ( While moving toward M ₁ , M ₂ , ..., or while performing the second direction input P as shown in (c) of FIG. 4, hold down the input unit 10 while pressing the center input key 13. Tilt toward a predetermined second direction indicating position (P ₁ , P ₂ ,...).

12 is a conceptual diagram illustrating an input method of the central combined input CM and CP.

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

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

For example, as shown in FIG. 17, when the first direction input M is provided in two stages, the first direction input M1 ₁ and the central input C in one stage are combined. the central input combination (CM1 ₁₎ and the first direction input of the second stage (M2 ₁₎ and a central combined input of central input (C) is a combination of a two-stage (CM2 ₂₎ is possible.

On the contrary, as shown in FIG. 18, the first direction input M is configured in one stage and the center inputs C1 and C2 are configured in two stages, thereby forming the center of the first direction input M ₁ and the first stage. input (C1) by the central combination input of the combined first stage (C1M ₁₎ and a second direction input (M ₁₎ a central combination type of the two-stage central input (C2) the combined second stage of the (C2M ₁₎ is It may be possible to arrange.

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

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

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

Direction combination input MP , PM )

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

That is, as shown in (b) of FIG. 4, the direction combination inputs MP and PM perform the first direction input M first, that is, the input unit 10 receives the first direction indication position M. FIG. In the state of moving to the second direction input (P) as shown in (c) of FIG. 4 is performed, or vice versa.

FIG. 13 is a conceptual diagram for describing a method of inputting direction combination inputs MP and PM.

FIG. 13A illustrates a case in which the second direction input P is successively performed while the first direction input M is first performed, and the direction combination input M ₁ P ₁ is the input unit 10. Indicates a case where the second direction input P is performed to the second direction indication position P ₁ while the is moved to the first direction direction position M ₁ .

On the contrary, FIG. 13B illustrates a case in which the first direction input M is successively performed while the second direction input P is first performed, and the direction combination input P ₁ M ₁ is the second direction indicating position. (P ₁₎ to indicate a second direction input (P) of claim 1 in a state of performing a direction instruction position (M ₁₎ in the first direction when the input (M) is performed.

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

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

That is, as shown in FIG. 13A, the second direction input P is input to the second direction indication position P ₄ while the input unit 10 is moved to the first direction indication position M ₂ . If this is done, the direction combination input M ₂ P ₄ is performed.

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

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

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

That is, in the case of the embodiment shown in Fig. 5, when the second direction input P for inputting 'ㅗ' and the first direction input M for inputting 'b' are performed simultaneously, Rather than entering characters, the Hangul character 'no' is entered by each input operation.

On the other hand, when one or more of the first direction input (M) and the second direction input (P) is provided to enable two or more stages multi-stage input, the direction combination input (MP, PM) by the number of combinations corresponding thereto It can be generated to maximize the input capacity.

Therefore, it is preferable to input characters having 50 or more phonemes, such as Chinese characters or Japanese characters, through the direction combination input MP and PM.

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

Directional rotation input (R)

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

Rotation of the input unit 10 may be implemented in various ways. For example, as illustrated in FIG. 14A, the first support unit 25a and the first support unit 25a may be moved relative to each other. It can divide and provide in 2 support part 25b.

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

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

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

Alternatively, as shown in (b) of FIG. 14, the rotation protrusion 77 is formed on one side of the input unit 10, and the left and right sides of the rotation protrusion 77 are respectively rotated in the direction of the rotation distance of the rotation protrusion 77. The rotation sensing units 68c, 68d, 68e, and 68f sequentially arranged may be provided.

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

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

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

Array of characters

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

However, the inputtable data according to the present invention is not limited to the above characters, and may include various function commands such as numbers, symbols or enters, spaces, and cancellations.

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

In the character input device 1 according to the present invention, the above-described first direction input M, second direction input P, center input C, center combined input CM, CP or direction combined input MP , PM), there is no particular limitation on the way of placing characters.

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

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

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

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

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

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

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

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

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

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

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

As shown in (a) of FIG. 16, four second direction indicating positions P ₁ , P ₂ , .. are provided, and second direction input P is provided to enable input in two stages. In this case, when arranging the alphabet, 'A, X', 'E, I', 'W, Y', 'O, U' are assigned to the second direction indication positions (P ₁ , P ₂ , ..), Each of the above-mentioned characters assigned by the second direction input P of the first and second stages may be distinguished and input.

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

Alternatively, when arranging Hangul characters, as shown in (b) of FIG. 16, 'ㅏ, ㅑ', 'ㅓ, ㅕ', 'ㅗ, ㅛ', 'TT, ? 'Can be duplicated and assigned so that the respective characters allocated by the second direction input of the first and second stages are distinguished and input.

Of course, contrary to that shown in Fig. 16, the first direction input M has four first direction indication positions M ₁ , M ₂ ,... The vowel character can also be entered by M).

In the case of arranging letters of similar shape as described above in the alphabet and Korean, the shape of the vowel character is associated with the second direction indicating position (P ₁ , P ₂ , ..) so that the user can easily become familiar with it.

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

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

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

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

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

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

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

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

In this case, when the first direction input M is performed while the second direction input P in the direction corresponding to the left mouse button is performed, dragging or dragging is possible as in the mouse. The signal processing associated with this can be used as the signal processing method in a mouse generally used.

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

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

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

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

31 to 33 illustrate examples of keyboard keyboard layouts in the case where the input unit 10 is provided with two left and right sides.

First, FIG. 31 shows an example in which the first direction input M and the second direction input P each have eight direction indicating positions, and are composed of two stage inputs.

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

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

FIG. 31A shows a basic input window in which data of 26 characters, 10 numbers, 12 F keys, 10 function keys, 4 direction keys, 2 changeover keys, and 64 data are all arranged. .

Symbols or other low frequency keys may be arranged in a Next window which is converted by selecting an N key provided in the center of the left keyboard display 74 (see FIG. 31B).

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

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

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

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

That is, α in FIGS. 32 and 33 represents a character input when the second direction input P is performed while the finger is in contact with the central input key 13, and β in FIGS. It shows the character that is input when only the two-way input (P) is performed.

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

  Therefore, in the embodiment shown in FIG. 31, the maximum number of data that can be arranged in one keyboard display unit 74 is 16 by the second direction input M of two stages and the second direction of two stages. 16 by input (P), 16 by combination of central input key (13) and second direction input (P), and 2 by central input (C) of two stages. Data arrays are possible, and in the case of two sets, a total of 100 data arrays are possible.

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

32 and 33 show an example of keyboard display in a small device such as the portable mobile communication terminal 100.

Referring to the drawings, FIG. 32 illustrates a case in which the first direction input M and the second direction input P each have eight direction indicating positions and are configured in one stage. FIG. 33 shows four direction indicating positions. And a case consisting of two stages.

Here, the outer line of FIG. 32 and the outer two lines of FIG. 33 are input by the second direction input P, and the inner line of FIG. 32 and the inner two lines of FIG. 33 are input by the first direction input M. FIG. 32 and 33 represent data input when each second direction input P is performed without placing a hand on the input unit 10.

In particular, in FIGS. 32 and 33 (a), the left side represents the mouse input window, the right side represents the basic input window, (b) the alphabet input window, the left side of (c) the numeric input window, and the right side the basic input window. Display the window.

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

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

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

32 and 33 are arranged so that letters, numbers, F keys, symbols, etc. can be inputted through mode change, unlike the embodiment shown in FIG. 31.

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

Meanwhile, when the terminal 100 is turned on, the mouse input window may be initially displayed on one side and the basic input window may be displayed on the other side.

In this state, you can switch to the alphabet input window or the number input window by selecting the desired mode through the default input window.

At this time, the input window on the left side can be used to change the mode through the central input (C) to be used as a mouse input window in any mode, the right side can be returned to the default input window.

Of course, in each of the input windows, the central combination input (CM, CP) to perform a mouse function at any time in a predetermined mode or to perform a mode change in the right input window.
