Description

  The present invention relates to a character input device including a stick and a selection button, and a character input method using the character input device, and more particularly, a stick in a moving direction similar to a writing order when a user writes characters with a pen. It is related with the character input device and its method which enable desired character input by moving sequentially.

  As a character input device according to the prior art, there is a character input device capable of inputting a corresponding character by pressing a specific key button such as a keyboard or a keypad. However, such a character input device has the inconvenience that it is necessary for the user to memorize input rules such as which key button to press when inputting a specific character. In addition, by displaying the characters that are input when the key button is pressed on each key button, the character input speed is reduced when it is not necessary to store the input rules. Further, when a large number of characters are input with one key button, that is, when a predetermined key button is used for inputting “a”, “B”, and “Chi” by mode, the key button There is a problem that it is difficult to display all the characters of each mode on the key button due to the area limitation.

  Further, as another character input device according to the prior art, there is a pen mouse that detects a character when a monitor or a specific plate is touched to input a character. The pen mouse is currently widely used as an input device such as a PDA (panel digital assist) device in that the user can input characters as if they were actually writing, and the user does not need to memorize input rules. It is used. However, since the pen mouse must be manufactured by a device separate from the device for inputting characters, such as a PDA, the user must take out the pen mouse from a certain storage space and press it on the PDA screen in a specific mode. In addition, since there is a high risk of loss, there is a restriction that it can be used together with a keyboard, keypad, etc. rather than using only a pen mouse. This is because a pen-shaped optical mouse that inputs characters using reflected light transmitted through an opaque plate or a built-in gyroscope or accelerometer detects changes in posture in space. The same applies to the input gyro mouse.

  In particular, such a character input device is more expensive and expensive than a keyboard or the like. There is a problem that it is unsuitable for general users in terms of cost. For example, pen mice are sold for hundreds of thousands to millions of won, and gyro mice are sold for hundreds of thousands of won or more.

  The present invention has been devised to solve such problems of the prior art, and the user stores the input rule using only a selection button including a stick and one or more buttons. It is an object of the present invention to provide a character input device that can input characters intuitively and a character input method in the character input device.

  In addition, according to the present invention, a character input device is provided that is inexpensive to manufacture and can be widely spread to users at a low price.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  The character input device according to the present invention includes a stick, a selection button, a storage unit, a search unit, a character generation unit, a display unit, and a verification unit. FIG. 1A is a diagram illustrating a stick 101 and a selection button 102 which are one component constituting the character input device of the present invention. FIG. 1B is a block diagram showing other components of the character input device of the present invention.

  Hereinafter, a character input process using the character input device according to the embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

  In step 201, the storage unit 103 stores the first table and the second table.

The first table includes the moving direction of the stick and character constituent units corresponding to the moving direction. FIG. 3 is a diagram showing an example of the first table when the character to be input using the character input device is “Korean”. As shown in FIG. 3, when the user grips the stick 101 and moves it to the right (reference numeral 301), the character constituent unit corresponding to this movement direction is “
, And when the user holds the stick 101 and rotates it 360 degrees (reference numeral 302), the character constituent unit corresponding to this moving direction is “
Can know. Further, as indicated by the reference numeral 303, there may be one or more character constituent units corresponding to the same movement direction.

The second table includes characters corresponding to an array of one or more character constituent units. FIG. 4 exemplifies an array of character constituent units when inputting characters in a unit of grapheme (Consonant / Vowel Unit) and a second table including characters corresponding to the array. As shown in FIG.
"
"When"
"
Corresponds to the array of character composition units. Furthermore, as shown in FIG.
"
"and"
"Is generated with a combination of characters.

  When the user moves the stick at step 202, the sensing unit 104 senses the moving direction of the stick 101 at step 203. For example, when the top end coordinate of the stick 101 is phased to a plane coordinate including the center point 101a, the sensing unit 104 senses the movement direction of the stick 101 by sensing the movement of the phased coordinate. it can.

  For example, when the user moves the right side while holding the stick 101 and then moves the stick 101 downward, the sensing unit 104 can sense that the moving direction is the same as the reference numeral 304 in FIG. The stick 101 according to the present invention itself has a restoring force, and when the user releases the stick 101, that is, when no force is applied, the stick 101 returns to its original position. That is, the phased coordinates automatically move to the center point 101a.

In step 204, the search unit 105 searches for a character unit corresponding to the sensed movement direction with reference to the first table. As shown in FIG. 3, when the moving direction of the reference numeral 304 is detected, the search unit 105 displays the character composition unit “
Or
".

  If the user again grips the stick 101 restored to the center point 101a and moves it downward, the sensing unit 104 senses the moving direction of the stick 101 as indicated by reference numeral 305 in FIG.

The search unit 105 is a character constituent unit corresponding to the movement direction sensed with reference to the first table.
".

Similarly, when the user holds the stick 101 restored to the center point 101a and moves it to the right side, the character constituent unit “
"Will be searched.

Steps 203 and 204 are repeated until a separate selection signal is input from the user. The user can input a selection signal by pressing the selection button 102. The selection signal is a signal indicating that the input of one unit of character desired by the user has been completed. The unit of the present embodiment is a syllable unit, a grapheme unit (consonant / vowel unit), or a word unit. (Word unit) is used. That is, if a grapheme unit is used, the user will be able to
)) Is input and then a selection signal is input. Also, when syllable units are used, the user can select one syllable (for example, “
)) Is input and then a selection signal is input.

The character composition unit "
"(Or"
)), "
"as well as"
When a selection signal is input from the user after the search is performed, the character generation unit 106 arranges the searched character constituent units before the selection signal is input to generate a character combination (steps 205 and 205). Step 206).

The character generation unit 106 selects the searched character constituent unit as “
”(First array) or“
”(Second array). The character generation unit 106 generates a character combination corresponding to the first array or the second array with reference to the second table.

The character combination corresponding to the first array is the character “
"When"
"In combination with"
"Or the character"
"When"
Is a combination of
" In other words, the character combination is generated using one or more characters each corresponding to the array. If there is no corresponding character combination as a result of arranging the searched character constituent units, the character generation unit 106 considers that the user does not match the movement of the stick 101 or the detection error of the detection unit 104 and ignores the arrangement. To come. That is, since there is no character combination corresponding to the second array, the character generation unit 106 does not perform any further processing on the second array.

  In step 207, the display unit 107 displays the character combination thus generated on a predetermined display unit (not shown).

  When the selection signal is input again for the displayed character combination, the verification unit 108 determines the selected character combination as the character input by the user (step 208 and step 209). The user can input a selection signal using the selection button 102. That is, the user inputs the selection signal in step 205 to notify that the unit of character input has been completed, and notifies the user if the character combination displayed as a result of the character input is the character he desires. Therefore, the selection signal in step 208 is input.

  In other words, the user looks at the character combination displayed on the display unit by the display unit 107, and if it matches the content he / she wishes to input, the user presses the selection button 102 to input the character combination.

  On the other hand, when there are a plurality of character combinations generated by the character generation unit 106, the display unit 107 displays a plurality of character combinations. When the selection signal for specifying any one of the displayed character combinations is input, the verification unit 108 determines the selected character combination as the character input by the user.

  According to still another embodiment of the present invention, the selection button 102 includes a plurality of direction buttons. That is, as shown in FIG. 1, direction buttons 102a to 102d can be provided. The display unit 107 can display a plurality of character combinations in association with each direction button.

FIG. 5 shows a case where a plurality of character combinations are displayed on the display unit 107 in association with the direction buttons. That is, the display unit 107 displays “
”And“
”Is displayed on the display screen in association with each other (see reference numeral 501), and the direction button 102d shown in FIG.
”. In addition, the display unit 107 displays “
”And“
”In association with each other (see reference numeral 502), the direction button 102a shown in FIG.
”.

Thus, since the character input device 100 according to the present invention displays each character combination in association with the direction button, the user selects any one of the plurality of character combinations displayed on the display unit. Which direction button of the selection buttons 102 should be pressed can be easily recognized. That is, the user tries to input the character "
", The direction button 102d can be pressed,
In order to select “”, the direction button 102a may be pressed.

  Further, the character input device 100 can use the specific direction button of the selection button 102 as a “Back Space” or “Delete” key. For example, when the direction button 102c of the selection button 102 is used as the backward key, when the user presses the direction button 102c, the display unit 107 can remove the character combination displayed on the display unit and can prevent further display. The unit removed by the backward key is set smaller than the character combination so that only one character included in the character combination displayed on the display unit or one character constituent unit included in the character combination is removed. You can also. The character generation unit 106 considers that the character constituent unit, character, or character combination removed by the backward key is not input from the beginning. In addition, the direction button 102c of the selection button 102 can perform a reverse key function only in a specific mode, and can perform a selection function similar to other direction buttons in other modes.

  On the other hand, in the above-described embodiment, the case of inputting a character in “character unit” has been described, but the case of inputting a character in “word unit” will be further described below.

For example, if the user
3, after the stick 101 is sequentially moved in the movement direction 304 → movement direction 305 → movement direction 301 → movement direction 301 → movement direction 307 → movement direction 305 → movement direction 301 in FIG. A selection button 102 is pressed to notify that the input of a desired word has been completed.

  The sensing unit 104 senses the movement of the stick 101, and the retrieval unit 105 retrieves a character constituent unit corresponding to each sensed movement direction with reference to the first table shown in FIG. The character generation unit 106 generates a character combination by arranging the character constituent units searched in this way with reference to the second table shown in FIG.

That is, when the stick 101 is moved in this way, the character generation unit 106 refers to FIG. 3 and FIG.
"(Third sequence) or"
(4th sequence) can be arranged.

One unit of character combination generated by the third array, that is, one word is “
, "
, "
"as well as"
It is. Since there is no character combination generated in the fourth array, the character generator 106 does not consider the fourth array any more as described above.

  The display unit 107 displays the generated character combination on the character input device 100 or a display unit connected to the character input device 100. FIG. 6 illustrates a case where nine display fields are implemented so that the display unit 107 can display up to nine character combinations on the display unit. Since there are four character combinations generated by the character generation unit 106, no character combinations are displayed in the remaining five display fields.

The user selects the direction button 102d and is the word to be input “
Can be selected. In this embodiment, the direction button 102b → the direction button 102a is sequentially pressed to
Or the like, the direction button 102a or the like may be sequentially moved to select a desired character combination.

Also, the word that the user tried to input is “
", The user presses the selection button 102e (center button) shown in FIG.
"Can also be entered.

  On the other hand, if the number of character combinations generated by the character generation unit 106 is within five, the display unit 107 displays either the selection button 102e or the direction buttons 102a to 102d rather than the display field 601 that requires the direction button to be pressed twice. By displaying the generated character combination in the display fields 602 and 603 that only need to be pressed once, user convenience can be achieved.

  If the probability is very low but the number of character combinations generated by the character generation unit 106 exceeds nine and not all character combinations are generated in the nine display fields shown in FIG. It is also possible to select a desired character combination by a method in which nine display fields of “next page” are displayed by pressing twice continuously.

  Hereinafter, a method in which the sensing unit 104 senses the moving direction of the stick 101 according to another embodiment of the present invention will be described in more detail.

  The sensing unit 104 subdivides an area in which the stick 101 can move into a plurality of unit areas according to angles with the center point 101a of the stick 101 as the center. For example, as shown by a reference numeral 701 in FIG. 7, the sensing unit 104 can divide the movable area into eight equal parts and divide them into unit areas 1-8.

When the stick 101 passes through the unit area 4, the sensing unit 104 senses that the stick 101 has moved in the moving direction as indicated by a reference numeral 306 in FIG. 3. That is, the user
"Is considered to have been entered.

When the stick 101 sequentially passes through the unit area 3 and the unit area 4, the sensing unit 104 senses that the stick 101 has moved in the moving direction as indicated by the reference numeral 304 in FIG. That is, the user
Or
"Is considered to have been entered.

  According to still another embodiment of the present invention, the character input device 100 decodes a character to be input by the user in consideration of not only the stick moving direction but also the stick moving distance. Hereinafter, a process of decoding a character input by the user in consideration of the moving direction and moving distance of the stick will be described in detail.

  The storage unit 103 of the character input device 100 according to the present embodiment stores the first table and the second table.

  The first table includes character constituent units corresponding to the moving direction of the stick and the moving distance of the stick. FIG. 8 is a diagram showing an example of the first table when the character to be input using the character input device is “Korean”. The movement distance of the stick in FIG. 8 is for indicating how far the stick 101 moves from the center point 101a. The specific meaning of “movement distance” in the first table will be described later with reference to FIG.

  Since the second table is the same as the second table in the above-described embodiment, a specific description thereof will be omitted.

  The sensing unit 104 senses the movement direction and the movement distance of the stick 101.

  The sensing unit 104 can sense the moving direction of the stick 101 in the manner described with reference to FIG. That is, the sensing unit 104 subdivides the area in which the stick 101 can move into a plurality of unit areas “according to the angle”, and then senses where the stick 101 moves in order in each unit area. The movement direction of the stick 101 is detected.

  In addition, the sensing unit 104 subdivides the area in which the stick 101 can move into a plurality of unit areas “depending on the distance”, and then senses where the stick 101 sequentially moves in each unit area. Thus, the movement distance of the stick 101 is sensed.

  For example, as indicated by reference numeral 901 in FIG. 9, the sensing unit 104 divides the area in which the stick 101 can move into four equal parts according to the distance, and divides the area into unit areas ad. As shown in FIGS. 8 and 9, the sensing unit 104 has a movement direction and a movement distance in the unit area 3, a → unit area 3, b → unit area 3, c → unit area 4, c → unit area 4, d. , It is detected that the user has moved the stick 101 as indicated by reference numeral 902 in FIG.

  Further, the stick 101 itself has a restoring force, and when the user releases the stick 101, that is, when no force is applied, the stick 101 returns to its original position. In other words, the phased coordinates automatically move to the center point 101a.

In addition, the search unit 105 searches the character constituent unit corresponding to the sensed movement of the stick 101 with reference to the first table. As illustrated in FIG. 9, when the movement of the stick 101 is detected, the search unit 105 displays the character composition unit “
Or
".

  As described above, the character input device 100 according to the present invention determines not only the moving direction of the stick 101 but also the moving distance so as to determine the character input by the user. Can be determined.

  After all the moving direction and moving distance of the stick 101 are detected and the character constituent unit that the user is trying to input is searched, the remaining process of inputting the character using the character constituent unit is the same as the above-described embodiment. Therefore, the description thereof is omitted.

  In this way, since the user can input all desired characters using only the stick 101 and the selection button 102 of the character input device 100, a large number of characters are different from character input devices such as keyboards and keypads according to the prior art. Since there is no need to provide a panel, it can be manufactured in a small size, has a high degree of space utilization, and has a low manufacturing cost. Therefore, the character input device 100 is used for a device having a limited size of the input device such as a camera, a game machine, a mobile phone, and an MP3 player.

  In addition, the character input device 100 according to the present invention basically inputs characters using the stick 101, and the direction of movement of the stick 101 for inputting characters is written by handwriting. Since the first table and the second table are set so as to be closely related to the stroke order, unlike the case of character input using a keyboard or a keypad, the user can input a specific character to input a specific character. Memorize the dial corresponding to, or remember the rules for entering specific characters (for example, CHUN-JI-IN method or EZ Hangul method input rules) There is no need to move the stick 101 so as to actually write characters by hand, so that the user can use the character input device 100 quickly. That.

  In the above-described embodiment, the case of inputting Korean is described as an example. However, this is merely an example, and the character input device 100 according to still another embodiment of the present invention is only Korean. Instead, it can be used as an input device for inputting various foreign languages such as English and Japanese. In the character input device 100 according to the present embodiment, the storage unit 103 stores the first table and the second table for each language mode.

  The display unit 107 displays the currently activated language mode (active language mode) as indicated by a reference numeral 1001 in FIG. 10. What is the language mode currently activated (selected) by the user? When attempting to input characters in a different language mode, another language mode is selected and the language mode is changed.

  For example, the storage unit 103 stores the first table as shown in FIG. 3 and the second table as shown in FIG. 4 in association with the Korean mode, and FIG. The first table as shown in FIG. 11 and the second table as shown in FIG.

  When the currently activated language mode is Japanese mode and the sensing unit 104 senses that the stick 101 has moved sequentially from the moving direction of the drawing symbol 1101 to the moving direction of the drawing symbol 1102, the searching unit 105. Refers to the first table as shown in FIG. 11A and searches for the character composition unit 1103 and the character composition unit 1104 respectively corresponding to the movement direction. Further, the character generation unit 106 generates “Y”, which is the character combination 1105 corresponding to the searched character constituent unit 1103 and the character constituent unit 1104, with reference to the second table as shown in FIG. To do.

  Through such a process, the user can input “Y”, which is a desired Japanese character, by moving the stick 101 in a manner similar to writing Japanese “Y” by hand.

  As described above, the Japanese input process has been described with reference to an example. However, the character input device 100 includes a first table and a second table for each language mode, and determines the moving direction or moving distance of the stick 101 sensed by the sensing unit 104. This is a method for determining an image (brush) that a user intends to input in consideration, and is used for an input device for inputting a large number of languages.

According to still another embodiment of the present invention, the second table stored in the storage unit 103 of the character input device 100 may include a plurality of character combinations corresponding to the arrangement of the character constituent units. For example, the second table shown in FIG.
As an array of character composition units corresponding to
", But the characters"
As an array of character composition units corresponding to
Can be further included.

That is, as shown in FIG. 3, the user also moves the stick 101 sequentially in the moving direction 301 → the moving direction 307.
", Or when the stick 101 is moved sequentially in the movement direction 301-> movement direction 305-> movement direction 301"
"Can be entered.

  The image input order (stroke order) of each character is generally specified by the language of each country. However, even if it is not the exact image input order, the number of image input orders may differ depending on the individual. For the convenience of the user, the character input device 100 according to the present invention includes one or more characters corresponding to a large number of image input sequences used by a person, as well as an array of character components that conform to an accurate image input sequence. An array of components can also be used.

  In addition, since each user using each character input device 100 provides a character input service that is optimal for the custom of writing characters, the character input device 100 allows each user to input an array of character components corresponding to each character. You can also

  The character input method according to the present invention is recorded on a computer-readable storage medium including program instructions for executing various operations embodied by a computer. The storage medium may include program instructions, data files, data structures, etc. alone or in combination. The storage medium and program instructions may be specially designed and configured for the purpose of the present invention, and may be known and usable by those skilled in the art in the field of computer software.
