The present invention relates to a system, method and wireless terminal for inputting a text message in a sliding manner on a touch screen. More particularly, the present invention relates to a text input on a concentric circle centered on a fixed area where a user's finger is fixedly touched on a touch screen. The present invention relates to a system, a method and a wireless terminal for inputting a text message in a slide manner on a touch screen in which a user can enter a text message more conveniently without a typo.

1 is a diagram illustrating a process of inputting a keypad and a text message of a conventional wireless terminal.

As shown, a keypad of a wireless terminal (for example, a portable telephone) is composed of numeric buttons 0 to 9 and function buttons having special functions such as * and #. Hangul consonants from 'to' ㅎ ',' · (천) '' ㅡ (지) ',' ㅣ (인) 'are assigned, and English letters from' A 'to' Z 'are assigned.

For example, when a consonant 'ㅅ' and 'ㅎ' are input using a wireless terminal, the consonant 'ㅅ' and the consonant 'ㅎ' are assigned to the same button. Select once and enter 'ㅅ'. After a certain time, select the same button twice and enter 'ㅎ'. That is, the user has to make three button selections to input two consonants, and wait a predetermined time to select the same button.

Therefore, a typical wireless terminal has a plurality of consonants assigned to one button, so it is cumbersome to press the button several times in order to input one consonant. There is a problem that it takes more time to enter a character because you have to wait and select it.

In addition, the user directly selects a button to which a predetermined consonant or celestial person is assigned when inputting a character, and thus, a user may input a typo because the character of the button is covered by a finger during the character input.

On the other hand, a touch button disposed in a wireless terminal (for example, PDA) using a touch screen has difficulty in selecting a button by arranging various types of buttons in a narrow area, and there is a problem in that an touch is generated.

In addition, the wireless terminal using the touch screen also assigns several characters to a single button screen (for example, assigns 'ㄱ' and 'ㄲ' together), so that different function buttons can be used to input the same button. It is a hassle to select and then press the corresponding button.

Japanese Laid-Open Patent Publication No. 2002-164980 (portable terminal) discloses a portable terminal capable of performing key operation with only a thumb by arranging a plurality of keys in a concentric circle with a predetermined point as the center. It only discloses a method of inputting characters using a thumb by arranging a plurality of inputable keys in an area to be inputted, and also reduces a typo generated when a button is selected and quickly inputs characters due to the characters assigned to the same key. The problem of not being able to remain.

An object of the present invention is to arrange a text input area on a concentric circle centering on a fixed area where a user's finger is fixedly touched on a touch screen, so that a user may input a text message more conveniently.

Another object of the present invention is to input a text message in a slide manner on the touch screen, and to reduce the occurrence of a typo when entering a text message by providing a direction guide when entering text.

The objects of the present invention are not limited to the above-mentioned objects, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.

And a character display area for displaying a character mapped to a character selection point at which the user's finger is located.

Specific details of other embodiments are included in the detailed description and the drawings.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and only the embodiments make the disclosure of the present invention complete, and the general knowledge in the art to which the present invention belongs. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

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

2 is a block diagram illustrating an internal block diagram of a wireless terminal system for inputting a text message in a slide manner on a touch screen according to an embodiment of the present invention. Here, the wireless terminal is a portable terminal that can communicate with a computer wirelessly, and has a mobility capable of real-time information retrieval and communication. For example, a wireless terminal can be understood as a cellular phone and a PDA.

As shown in the drawing, the wireless terminal 100 for inputting text in a slide manner on the touch screen includes a touch detector 110, a position checker 120, a direction guide generator 130, a mode setting unit 140, The storage unit 150, the sound effect generator 160, the display unit 170, and the controller 180 are configured to be included.

The display unit 170 is disposed so that the concentric grid and the radial grid intersect on a fixed area where the user's finger (for example, a thumb) is fixedly contacted, a concentric circle centered on the fixed area, Character input area in which a predetermined character is mapped to the intersection point (that is, a character selection point), and a character arrangement in which the characters are arranged in an order corresponding to the character selection point at which the concentric grid and the radial grid intersect. And a second display unit 172 providing a region and a second display unit 172 providing a character display region displaying a character mapped to a character selection point where a user's finger is located in the character input region. do.

In addition, when the user's finger contacts the radial grid, the first display unit 171 displays a direction guide for guiding the input progress direction on the radial grid where the finger is in contact, and the user's finger crosses the concentric grid and the radial grid. When a character is located at a character selection point, a highlight is displayed indicating that the character is selected on the character disposed in the character arrangement area.

In addition, when the user's finger is not in contact with the fixed area, the first display unit 171 provides a menu for setting a text input mode so that the user can change the text input method. Hereinafter, the display unit 170 will be described in detail with reference to FIG. 3.

The touch detector 110 detects whether the user touches the finger, that is, detects whether the user's finger (for example, the thumb) touches the fixed area of the first display unit 171. Here, the sensing of whether the user touches the finger is based on whether the user's finger is in contact with the fixed area, and the controller 180 displays a screen for inputting a predetermined character on the first display unit 171. This is because the menu screen for setting the mode is determined.

The position checker 120 checks a user's finger position by checking a movement direction and a distance of the user's finger. For example, when a user's finger touches the radial grid disposed in the text input area and moves in a slide manner, the position checker 120 checks the direction and the moving distance of the user's finger to position the finger of the current user. The position value of the checked character selection point is checked, and the position value of the checked character selection point is transmitted to the controller 180. Here, the slide method refers to a method of moving from a fixed area of the first display unit 171 to a character input area to which a predetermined character is mapped in a state where a user's finger is in contact, and then returning it back to the fixed area.

The direction guide generation unit 130 provides a guide on the input progress direction according to the movement of the user's finger. For example, when the user's finger touches the radial grid disposed in the text input area of the first display unit 171, the direction guide generator 130 highlights the direction guide (ie, highlights in the corresponding direction) on the radial grid. By guiding the user to move the input direction.

In addition, the direction guide generation unit 130 displays an extended guide on the concentric grid of the character selection point where the user's finger is located. Here, the expansion guide serves to display a concentric grid on which the character selected by the user is mapped.

The mode setting unit 140 sets the text input method of the wireless terminal 100 in the text input mode selected by the user. Here, the type of the character input mode may be understood as Korean, English (lowercase letters, uppercase letters), symbol letters, numbers, and the like.

The storage unit 150 stores a text value mapped to a text selection point at which the concentric grid and the radial grid of the first display unit 170 intersect with each other. Here, the storage unit 150 stores the position value of the character selection point corresponding to the characters (Korean, English (lowercase, uppercase), symbol characters, numbers, etc.) mapped to the character selection point.

For example, when the controller 180 requests information about a character mapped to a predetermined position, the storage unit 150 searches for a character mapped to a corresponding point and transmits the found character to the controller 180.

In addition, the storage unit 150 stores the text input mode of the wireless terminal 100 set from the mode setting unit 140.

For example, when the character input mode of the wireless terminal 100 is Korean, if the location value of the character selection point is (1,1), the storage unit 150 stores that the corresponding Korean is 'ㄱ'. .

The sound effect generator 160 generates the sound effect when the user's finger is positioned at the character selection point to which the predetermined character is mapped or when the user's finger returns to the fixed area. Here, the sound effect generated when the user's finger is located at the predetermined character selection point serves to inform the user that the character is selected, and the sound effect generated when the user's finger is returned to the fixed area is selected. 2 is a function for notifying that the display unit 172 is displayed. In addition, different sounds may be generated according to the area (or point) where the user's finger is located.

The controller 180 controls the touch detector 110 to detect whether the user's finger is in contact with the fixed area of the first display unit 171, and as a result of the check of the touch detector 110, the user's finger is moved. When contacting the fixed area, the first display unit 171 provides a screen through which a user can input text.

In addition, the controller 180 controls the position checker 120 to check the direction of the user's finger and the moving distance, and controls the guide generator 130 to provide the direction guide in the input progress direction according to the user's finger movement. Do it.

In addition, the controller 180 searches for a character mapped to the character selection point where the user's finger is checked by the location checker 120 through the storage unit 150, and the controller 180 also includes a mode setting unit ( Check the text input mode currently set in the wireless terminal 100 through 140.

In addition, the controller 180 controls the sound effect generator 160 to generate a predetermined sound when the user's finger is positioned at the character selection point to which the predetermined character is mapped, and selects when the user's finger returns to the fixed area. The character is controlled to be displayed through the second display unit 172.

Meanwhile, the present invention may input a text message using both hands, and the screen provided when inputting a text message using both hands may include a fixed area, a text input area, and a text arrangement area changed according to the two-handed input method. (See FIG. 8 hereinafter).

3 is a diagram illustrating a wireless terminal for inputting a text message in a slide manner on a touch screen according to another embodiment of the present invention.

As illustrated, the wireless terminal 100 is divided into a character manipulation area 10 and a character display area 20.

The character manipulation area 10 is arranged so that the radial grid 12a and the concentric grid 12b intersect on the fixed area 11 where the user's finger is fixedly contacted with the concentric circle centered on the fixed area. In order corresponding to the character input area 12 in which predetermined characters are mapped to the character selection point 12c to be crossed, and the character selection point 12c at which the radial grid 12a and the concentric grid 12b intersect. It is comprised including the character arrangement area | region 13 which arrange | positions the said character.

In addition, when the user's finger is in contact with the predetermined radial grid 12b, a guide 14 for the input progress direction according to the movement of the user's finger is provided, and mapped to the character selection point 12c to correspond to the corresponding character. A highlight mark 16 is provided.

In the text manipulation area 10, a button (for example, a delete button) having a function of deleting an input character and a mode indicating a text input mode (for example, an uppercase letter in English) currently set in the wireless terminal 100 are provided. Display button can be displayed.

The character display area 20 displays a character mapped to the character selection point 12c where the user's finger is located.

For example, a predetermined radial grid 12a (e.g., G, to which a character desired to be input in a sliding manner is mapped while a user makes a finger (e.g., a thumb) in contact with the fixed area 11 is provided. Moving to column H, column I, a guide 14 for the direction of input travel is provided. Here, the slide method refers to moving the position and the direction of the user's finger in the state in which the user's finger is in contact with the character manipulation area 10.

Then, with the user in contact with the radial grid 12a (e.g., columns G, H, I), the radial grid 12a and the concentric grid 12b provided with the guide 14 When the finger is positioned at the intersecting letter selection point 12c, the highlighting mark 16 is provided to the letter mapped to the letter selection point 12c where the finger is located (for example, English letter 'H').

Then, the user fixes the position of the finger 'H') is displayed. That is, in the character input method according to the present invention, after the user makes a thumb contact with the fixed region 11, the user moves his or her finger to the character selection point 12c to which the character desired to be input in a slide manner is mapped and fixed again. A predetermined text message may be input by performing a process of returning the thumb to the area.

3B illustrates a case in which the current character input mode of the wireless terminal 100 is Korean. After the user touches a finger (for example, a thumb) to the fixed area 11 to input a consonant 'ㅉ' The user's finger is moved to the letter selection point 12c to which the consonant 'ㅉ' is mapped in a slide manner. Next, when the user's finger is returned to the fixed region 11, the consonant 'ㅉ' is input to the character display region 20 (1).

On the other hand, when the user has to input the consonant 'b', but accidentally placed the finger at the character selection point 12c where the radial grid 12a to which the consonant 'ㅌ' is mapped and the concentric grid 12b intersect, When the user moves the finger to the concentric grid 12b to which the consonant 'b' is mapped and returns the finger to the fixed area 11, the consonant 'b' is input to the character display area 20 (2).

4 is a diagram illustrating a process of providing a direction guide in a wireless terminal for inputting a text message in a slide method on a touch screen according to another embodiment of the present invention.

As shown, it is assumed that the fixed region 11 where the thumb is located is Oz, and the contact position of the thumb is P. Further, the direction guides for the arbitrary letters A, A ', and A "arranged in the same direction are called Az, respectively, and the letter selection points at which the radial grids of the A, A', A" and the concentric grid intersect are a1, Let a2, a3, and assume that the extended direction guide portions are Az1, Az2, Az3.

For example, after the user's thumb is in contact with the fixed area 11 (ie, P∈Oz), if the user moves the thumb and places it in columns A, A ', A "(ie, P∈Az) , A directional guide (ie Az) is provided (FIG. 4A).

In addition, when the user's thumb is located at a1 (i.e., P 효과 a1), an effect sound indicating that the letter A is selected is generated, and an extended direction guide (i.e. Az1) is generated (Figs. 4b and 4c). .

Then, when the user's thumb is located in the fixed area 11 (ie, P∈Oz), the selected letter A is input to the letter display area (not shown).

5 is a diagram illustrating a process of inputting a character and a process of changing a text input mode in a wireless terminal for inputting a text message in a slide method on a touch screen according to another embodiment of the present invention.

And a character manipulation area 10 including a character input area 12 and a character arrangement area 13 and a character display area 20.

As shown in FIG. 5A, when the user's thumb is in contact with the fixed area 11 of the character manipulation area 10, the user moves the thumb in the G, H, and I direction in a sliding manner. Direction guides 14 are displayed on the G, H, and I lines. Here, the circle mark (that is, ○) shown in the figure is shown to indicate the point where the user's thumb is located, and is not displayed on the actual character manipulation area 10.

Then, moving the user's thumb to the second letter selection point where the radial grid 12a and the concentric grid 12b of the G, H, and I lines intersect, an extension guide 14a is generated, and the letter H An effect sound is generated to indicate that it is selected.

Then, when the user returns the thumb to the fixed area 11, the letter H is displayed in the letter display area 20. Here, a predetermined sound effect may be generated when the letter H is displayed in the letter display area 20, and the sound effect indicating that the letter is selected and the sound effect generated when the letter is displayed may be different from each other.

5B illustrates an example in which a user incorrectly selects a text while inputting a text message in a slide method using a thumb.

As shown in FIG. 5B, when the user moves the thumb in the G, H, I line direction in a sliding manner while the user's thumb is in contact with the fixed area 11 of the character manipulation area 10, Direction guides 14 are displayed on the G, H, and I lines.

Then, when the user moves the thumb to the first letter selection point at which the radial grid 12a and the concentric grid 12b of the G, H, and I lines intersect, an extension guide 14a is generated, and also the letter G An effect sound is generated to indicate that is selected.

At this time, if the user selects the wrong letter, if the thumb is moved along the expansion guide 14a to the desired letter (for example, the letter D), the direction guide 14 and the line D, E, F are placed. The extended direction guide 14a is displayed.

Then, when the user returns the thumb to the fixed area 11, the letter D is displayed in the letter display area 20. Here, a predetermined sound effect may be generated when the letter D is displayed in the letter display area 20, and the sound effect indicating that the letter is selected and the sound effect generated when the letter is displayed may be applied differently.

FIG. 5C illustrates an example in which a user inputs a sign character by changing a text input mode while a user inputs a text message in a slide method using a thumb.

As shown in FIG. 5C, when the user's thumb is in contact with the fixed area 11 of the character manipulation area 10, the user selects a character to which characters to be input in a sliding manner are mapped using the thumb. By selecting the point, the text message 'spring' is displayed in the text display area 20.

Next, when the user wants to input a sign character, if the thumb that touches the fixed area 11 is removed from the fixed area 11, the character input mode (for example, Korean, A menu 30 is provided for setting up a zero, a zero, a symbol, and a number).

Then, when the symbol button is selected from the provided menus, the character manipulation area 10 is changed to a symbol input mode screen, and special characters for inputting a symbol are provided in the character manipulation area 10. Then, the user slides to select the character selection point to which the desired symbol is mapped.

Then, when the user wants to input the character again, the thumb 30 which is in contact with the fixed region 11 is removed from the fixed region 11 so that the menu 30 for setting the text input mode is provided. Then, when the Hangul button is selected from the provided menus, the character manipulation area 10 is changed to the Hangul input mode screen. On the other hand, when the user wants to use the spaced writing function at predetermined intervals, the spaced writing function can be used by selecting the displayed direction key together with the menu 30 for setting the character input mode.

Accordingly, the corresponding letter (or number) selected by the user is displayed on the letter display area 20.

8 is a flowchart illustrating a method of inputting a text message in a slide manner on a touch screen according to another embodiment of the present invention.

First, the controller 180 requests the touch sensor 110 to detect whether a user's finger (for example, a thumb) is in contact with the fixed area 11 (S200).

As a result of the detection, when the user's thumb contacts the fixed area 11 (S210), the controller 180 checks a text input mode currently set in the wireless terminal 100 stored in the storage 150, and inputs the corresponding text. The mode is displayed on the character arrangement area 13 of the character manipulation area 10 (S220). Here, the type of the character input mode may be understood as Korean, English (lowercase letters, uppercase letters), symbol letters, numbers, and the like.

Next, the controller 180 controls the user's thumb movement direction and position to be checked through the position checker 120 (S230), and as a result of the check, the user's thumb moves in a predetermined direction of the character input area 12. When moved, the direction guide generation unit 130 is controlled to provide the direction guide 14 in the input progress direction according to the user's thumb movement (S240 and S250). Here, the character input method uses a slide method for moving the thumb in contact with the character manipulation area 10.

Then, the controller 180 controls the user's thumb to the character selection point (that is, the point where the concentric grid 12a and the radial grid 12b intersect) through the position checker 120. Check if it is located. If the user's thumb is located at a predetermined character selection point (S260), the controller 180 controls the display unit 170 to display a highlight on the corresponding character disposed in the character arrangement area 13, and the effect sound. The generation unit 160 generates an effect sound indicating that the predetermined character is selected (S270).

Next, when the user's thumb returns to the fixed area 11 as a result of the check of the position checker 120 (S280), the controller 180 controls the display 170 to correspond to the character display area 20. The character is displayed (S290). Here, a predetermined sound effect may be generated when the corresponding character is displayed in the character display area 20, and the sound effect indicating that the character is selected and the sound effect generated when the character is displayed may be differently applied.

On the other hand, as a result of detecting whether the user's thumb is in contact with the fixed region 11, when the user's thumb is not in contact with the fixed region 11 (S210), the controller 180 controls the character manipulation area 10. A menu for setting a text input mode is displayed on the screen so that the user can change the text input mode (S215).

In addition, when the user's thumb is not returned to the fixed region 11 as a result of the check (S285), the controller 180 determines whether the user's thumb is moved to a predetermined direction and position through the position checker 120. Check

When the user's thumb is moved in a predetermined direction and position as a result of the check, the process of step S250 is performed again. When the user's thumb is not moved in the predetermined direction and position as a result of the check, the process is again performed.

Therefore, by arranging a text input area in which predetermined characters are mapped on concentric circles around the user's thumb, it is possible to input a text message quickly and conveniently.

In addition, the user performs a text input in a slide method using the thumb, and by providing a direction guide in the direction of movement of the thumb when the user enters the text can reduce the typo generated during text message input.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, it is to be understood that the embodiments described above are exemplary in all respects and not restrictive.

According to the system, method, and wireless terminal for inputting a text message in a slide manner on the touch screen of the present invention as described above, there are one or more of the following effects.

By arranging a text input area on a concentric circle around a fixed area where the user's finger is fixedly touched on the touch screen, the user may enter a text message more conveniently.

In addition, by inputting a text message in a slide method on the touch screen, there is an advantage that the wireless terminal does not malfunction because it does not make a mistake of selecting another character when the finger moves.

In addition, by providing a direction guide according to the direction of the user's finger movement, and by providing a highlight mark on the selected text from the user, by re-confirming the text to be input to the user, there is an advantage that the typo can be reduced during text message input.

In addition, by selecting a character selection point to which the character is mapped, instead of directly selecting a character to be input by the user, there is an advantage that the occurrence of a typo may be reduced when the character is input since the character is not hidden.

In addition, by generating a sound effect when a predetermined character is selected or the selected character is displayed, there is an advantage that it is possible to accurately know whether the character is selected and displayed.

In addition, by mapping only one character to a character selection point, there is an advantage that the text message can be entered more quickly.
