Description

CHARACTER INPUT INSTALLATION OF TOUCH PHONE AND CHARACTER INPUT METHOD THEREOF}

The present invention relates to a character input of a watch phone, and more particularly, to a character input device of a watch phone and a character input method using the same based on a screen button in which a few reference characters are written. It is about.

In general, a mobile terminal provides a voice call function and a text message transmission function. In order to transmit a text message from the mobile terminal, first, text is input using the keypad of the mobile terminal. In this way, you complete the text message and send it. Conventional portable terminals input characters using only a mechanical keypad, but recently, characters may be input using a virtual keypad on a touch screen.

In the above-described keypad or the virtual keypad, a plurality of letters and numbers are written on one button to select and input arbitrary letters or numbers according to a predetermined selection method. Therefore, when the predetermined key is to be input by tapping a plurality of times, the number of tapping may be confusing in the tapping process. In particular, when a large number of characters are mapped to one key, a lot of tapping must be performed to input characters mapped in subordinate order. In this case, it is difficult for a user to immediately know a character that can be input immediately.

In order to overcome this, in recent years, a methodology for easily performing text input on a touch screen is disclosed. For example, referring to the contents of a known terminal and a method for inputting a touch screen, the portable terminal 100 includes a touch screen 20. In the text input mode, the virtual keypad 21 and the text input window 22 are displayed on the touch screen 20.

The portable terminal 100 may include only the virtual keypad 21 or may include a mechanical keypad together with the virtual keypad 21. The above described virtual keypad 21 is divided into a predetermined number of keys. In general, the virtual keypad is divided into 16 keys. At least seven of each key is mapped to a predetermined number of specific characters. Each key displays a predetermined number of characters simultaneously among the mapped characters.

For example, the '2' key displays a, b, and c at the same time, and the '9' key displays w, x, y, and z at the same time. In this case, each key displays a character which can be immediately inputted from other characters. Immediately inputable characters are characters that a key can enter in the current state. In the case of the '2' key, a is displayed in bold and large, unlike b and c. This tells us that a is now entered when the '2' key is tapped once. Tapping the 2 'key once again makes b an immediate character. In addition, in order to display a character which can be immediately inputted is distinguished from other characters, it may be displayed in bold and large, or may be displayed in a different color.

As described above, the conventional text input method allows a user to conveniently enter a text by displaying a text that can be immediately input among the characters mapped to a specific key of the virtual keypad when the text message is created. In addition, it is possible to convert the characters mapped to each key can be used in other language environments, and has the effect of simplifying the input of uppercase and lowercase letters and special characters.

However, the above-described character input method marks characters which can be immediately inputted through color or size change in order to identify mapped characters, but it is still difficult to recognize characters because many characters are written on one key button. It is happening. In addition, there is a risk of harming the beauty of the screen configuration by changing the size of the character, as well as the elderly who are not good at the character input is difficult to use or recognize such a character input method has a problem that the practicality is lowered.

The present invention was created to solve the above problems, and an object of the present invention is to provide a watch phone capable of easily inputting letters or numbers based on a few key buttons and the direction of drag centering the buttons.

Provides a graphic output unit 209 and screen information set by the graphic output unit 209 to hold graphic coordinate information on the screen information, and flow coordinate information input from the coordinate conversion unit 211. The UI processing unit 207 for receiving the detection direction of the drag based on the graphic coordinate information and the flow coordinate information, the drag direction and the graphic coordinate information After selecting the text on the basis, the control unit 201 to provide the character information according to the text combination to the UI processing unit 207, and outputs the corresponding character information to the terminal operation unit according to the instruction of the UI processing unit 207, Character information is stored, including screen graphic information, based on a combination of a memory 203 in which tabled text information corresponding to the drag direction is stored, and text information selected by the controller 201. It consists of a character processing unit 205 for generating a.

The flow coordinate information is coordinates according to the user's screen watch or drag on the screen, and may be X and Y axis coordinate information on the screen in the watch operation, and include start point coordinates and end point coordinates in the drag operation. Accordingly, the controller 201 recognizes the direction of dragging based on the coordinate change according to the dragging operation, and selects any one text based on the dragging direction.

The tabled information stored in the memory 203 is a cluster of textualized information having any unique code or address as shown in FIG. 4, and includes Korean, English (upper / lower case), and numbers. It may be constructed in a star language. In the exemplary embodiment of the present invention, the table information is configured in Korean and English, but may be described in Korean for any country.

The drag direction is from the top of the key button to the center of the key button (hereinafter referred to as the center of the top) and from the bottom of the key button to the center of the key button (hereinafter referred to as the bottom center) and from the center of the key button The upward direction (hereinafter, referred to as the upper center), and the downward direction (hereinafter referred to as the lower center) of the key button from the center of the key button, the diagonal drag direction may be set as necessary. If one text corresponding to the drag direction is set, the text list may be converted according to the characteristics of the character. For example, the UI processing unit 207 provides a list of a few Korean texts on the screen for inputting Korean characters. After the consonant (choice) text is selected, the UI processor 207 automatically provides a vowel (neutral) text list and collects the vowel (neutral). The screen control is performed to provide a list of consonant (final) texts automatically after the texts of the screen are selected. If there is no finality, the silent consonant text is selected to control to move to the next consonant (consonant).

3 is a main configuration diagram illustrating a text selection function of the controller 201 according to the present invention. As shown in the drawing, whether the drag on the screen is determined based on the flow coordinate information and the graphic coordinate information provided by the UI processing unit 207, and the direction or vector of the drag is calculated based on the start point and the end point of the coordinate information. The drag determination module 301, a vector code generation module 303 for generating a preset code corresponding to the drag direction of the drag determination module 301, and a key button corresponding to the graphic coordinate information. It consists of a table information extraction module 307 for selecting any text of the table information 305 in preparation for the vector code output from the vector code generation module 303.

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings. First, the terminal operating unit 215 performs a unique function of the terminal, and the UI processing unit 207 displays the graphic screen previously stored in the memory 203 so as to correspond to the unique function of the terminal. Through the watch screen 213 is provided through. Accordingly, the user may watch TV or perform handset with an arbitrary terminal by using the screen displayed on the watch screen 213.

Then, when the user writes a text message or wants to take a note using the terminal, the user switches to the text input mode of the terminal. For example, when sending a text message, the UI processing unit 207 provides a text message input window as shown in FIG. 5A. The input window is graphic information preset to the memory 203, and the UI processor 207 extracts the corresponding input window information from the memory 203 and is provided to the watch screen 213 through the graphic output unit 209.

As illustrated, the input window includes a display window 501 for displaying input text or characters, and a selection window 503 for text input, and the selection window 503 includes a few basic consonants 505. After being displayed, the upper center consonant, the lower center consonant, the upper center consonant, and the lower center consonant are displayed as up and down ends of each basic consonant 505.
The upper center consonant is located at the top of the basic consonant, and the consonant is recognized when dragging from the direction toward the center of the basic consonant, the lower center consonant is located at the bottom of the basic consonant, and the center of the basic consonant therefrom The consonant is recognized when dragging in the direction, the upper center consonant is located at the top of the basic consonant, the consonant is recognized when dragging from the basic consonant to the upper direction of the basic consonant, the lower center consonant is the basic consonant Located at the bottom of, the consonant is recognized when dragging from the basic consonant to the bottom of the basic consonant. In the exemplary embodiment of the present invention, since only one consonant is positioned at the bottom of the basic consonant, only a lower center consonant may exist.
Here, the upper center consonant, the upper center consonant, and the lower center consonant, including the basic consonants, are formed around the basic characters (a, c, ㅁ, ㅅ, ㅇ) of Hangeul or formed according to the keyboard layout of the keyboard. Could be. In the present embodiment, the consonant array is illustrated according to the keyboard layout of the keyboard, and two upper consonants are provided and one lower consonant is provided around one basic consonant 505.

Here, the upper consonants 507 are divided into consonants selected when dragging toward the center from the top of the basic consonants 505 and consonants selected when dragging downward from the top of the basic consonants 505, as indicated by arrows. The lower consonants 509 provided alone are consonants selected when dragging downward with respect to the corresponding basic consonants 505.

Each text of the selection window 503 displayed on the watch screen 213, that is, the basic consonant 505 and the upper and lower consonants 507 and 509 holds the corresponding graphic coordinate information according to each graphic process. This is retained by the UI processing unit 207.

Then, when the user wants to select a random consonant, for example, 'j' among the upper consonants 507, the user drags the top 'j' of the basic consonant 505 toward the center toward the starting point. Thus, the end point of the drag is located inside the basic consonant 505. The coordinate converting unit 211 generates drag coordinate information by recognizing a start point and an end point according to the drag direction. The drag coordinate information is X-axis and Y-axis coordinates corresponding to the screen of the watch screen 213.

The coordinate converter 211 provides the drag coordinate information to the UI processor 201, and the UI processor 207 includes coordinate information corresponding to the starting point of the drag, and coordinates corresponding to an end point of the drag. Extract the information. Here, when the drag coordinate information corresponding to the starting point selects an arbitrary basic consonant 505, the UI processor 207 extracts text information corresponding to the basic consonant.

The drag determination module 301 of the controller 201 calculates a vector of corresponding coordinates based on drag coordinate information. The coordinate vector determines whether the end point exists inside the primary key, at the top of the primary key, or at the bottom of the primary key.

Thereafter, the vector code generation module 303 generates coded vector information based on the coordinate vector provided from the drag determination module 301. This creates a vector with either start point drag coordinates or end point drag coordinates around any key button.

As such, the vector code generation module 303 includes the text information corresponding to the selected key button, and provides the vector information corresponding to the drag point starting point or ending point in the drag state to the table information extraction module 307. The table information extraction module 307 extracts table information corresponding to a vector code that meets a basic text, that is, a basic consonant and a key of the basic vowel.

The UI processing unit 207 is a text of the corresponding key button when the starting point or the ending point coordinates for dragging correspond to a range of preset graphic coordinate information, for example, a key button and a coordinate range on the graphic corresponding to the top and bottom of the key. Information is provided to the control unit 201. Thereafter, the remaining coordinates (start point drag coordinates or end point drag coordinates) are transmitted to the controller 201.

After receiving the drag coordinate information, the controller 201 determines the start point and the end point of the drag from the selected text information. This determination will be made based on the coordinate information. For example, when the starting point drag coordinate is present inside the key button and the ending point drag coordinate is present at the bottom of the key button, the controller 201 starts at the center and corresponds to the downward drag direction. If the endpoint drag coordinates are present at the top of the key button, the controller 201 does not select text because there is no table information corresponding to the upward drag direction.

As such, when any one consonant is selected, the controller 201 transmits a code corresponding to the consonant to the character processor 205. The character processing unit 205 waits for continuous text input, with only one consonant (first consonant) currently input. The control unit 201 instructs the UI processing unit 207 to switch screens, and the UI processing unit 207 provides a screen for inputting a vowel (neutral) to the graphic output unit 209 after consonants. Then, if any one vowel is selected, the code corresponding to the vowel is transmitted to the character processor 205. The character processing unit 205 waits for continuous text input while being input only up to the current vowel (neutral). The control unit 201 instructs the UI processing unit 207 to switch screens, and the UI processing unit 207 provides the graphic output unit 209 with a screen for inputting consonants (final) following the vowel (neutral). . Subsequently, when one consonant is selected, a code corresponding to the consonant is transmitted to the character processing unit 205 to complete a single letter having initial, neutral, and final consonants.

Here, an example of a character input such as "a" without a consonant of finality is as follows. On the screen for the first consonant input, drag from the top of the basic consonant 'ㄹ' to the inside of the primary key and select "ㄱ". When the screen for inputting the vowel is changed, click the default vowel 'ㅏ' to select "ㅏ". Enter it. Then, when switching to the consonant input screen for the final input, select the silent consonant text "☆" (508) in Figure 5a to input a non-pronounced support to complete a letter.

As shown in FIG. 5B, the selection bar 503 displays the upper bar 511 and the lower bar 513 including the basic bar 515. The UI processing unit 207 holds coordinates of each of the key buttons for the basic collection 515, that is, graphic coordinate information. As for the vowel input, the same method as the above-described consonant input is applied.

In the input of such a character, in order to select the overlap of 'ㄵ', '중', 'ㄻ', 'ㄼ', etc. as shown in the tabled information of FIG. The user selects overlapping consonants among the basic consonants 505, the upper consonants 507, and the lower consonants 509. Here, the selection refers to an overlapping click (or drag), and selects two consonants of the plurality of consonants by overlapping them. The same method is used to select a double vowel.

As such, when the table information extraction module 307 of the controller 201 selects the initial, neutral, and final properties, a code corresponding to the text is provided to the character processing unit 205 to generate one character. The character generated by the character processor 205 is provided to the UI processor 207 and displayed on the display window 601 through the graphic output unit 209. In addition, when a plurality of such characters are input and one message is completed, the controller 201 transmits the corresponding message to the terminal manager 215 according to a user's instruction.

6 illustrates a screen configuration for selecting English text other than Korean according to another embodiment of the present invention. As shown, FIG. 6 is divided into a display window 601 and a selection window 603. The selection window 603 has a downward text 607 having a drag start point at the top of the primary key and a click inside the primary key. And a downward text 609 having a drag start point therein and an upward text 605 having a start point at the bottom of the primary key.

Although the present invention describes a text display according to a plurality of methods as described above, in the present invention, by selecting the direction of drag along with the display, text selection on the watch screen is facilitated.

As described above, the present invention can reduce malfunction by arranging a few key buttons displayed on the watch screen so that they are not adjacent to each other. In addition, by selecting the text by recognizing the user's drag direction centered on a few key buttons, the watch screen in a narrow space can be utilized widely. In particular, when inputting Hangul, separate consonants and vowels when necessary. As you display, most text can be entered in one movement. When dragging text input, most finger movements are pushed down to induce easy and less confused finger movements. In the present invention, it is considered that industrial application value is extremely high by increasing the efficiency of text selection by sufficiently applying the hitch and drag function, and securing the mobile niche. In addition, if the present invention is used to input Hangul, it is possible to expect the effect of preventing the destruction of Hangul due to omission of the finality.
