FIG. 2 is a flowchart illustrating a sequence of a text input method that may be performed in the mobile terminal of FIG. 1.

Referring to FIG. 2, the controller 120 arranges one or more virtual keyboards in which one or more characters are disposed in a virtual space (step S210). In one embodiment, the letters disposed on the virtual keyboards may include letters, numbers, marks and / or symbols. In another embodiment, the text placed on the virtual keyboards may include a command code for performing a particular command. The virtual space is a space formed at the current location of the mobile terminal. In this virtual space, a mobile terminal and one or more virtual keyboards having one or more characters arranged thereon are moved and moved to a location or area corresponding to the characters arranged thereon to select and input the characters.

FIG. 3A is a view illustrating a mobile terminal displayed on a screen with virtual keyboards having letters arranged thereon, and in particular, shows a preferred embodiment in which two similar virtual keyboards are simultaneously placed in a virtual space. That is, when the torso of a user carrying a mobile terminal for text input in a virtual space is an axis, a space near the axis is a space or spaces in a direction in which the pull (pull or the arm is bent). The space away from the axis is indicated by an arrow to indicate that the space is in the direction of pushing (pushing or extending). The reason for arranging the two similar virtual keyboards is to increase the speed and convenience of character input. The layout shown in the drawings is an example for describing the disclosed technology, and various layouts may exist according to the number and type of virtual keyboards or the text input content and method.

FIG. 3B is a diagram illustrating a virtual keyboard on which characters are arranged, and FIG. 3C is a diagram illustrating a mobile terminal on which the virtual keyboard of FIG. 3B is displayed. FIG. 3A illustrates a situation in which two similar virtual keyboards in which characters are arranged are arranged in parallel and the corresponding characters are input by moving in the virtual space of the mobile terminal with respect to the arranged virtual keyboards. For details, refer to FIGS. 6A to 6F and 7A to 7D and the description thereof. Hereinafter, for convenience of description, a description will be given based on one virtual keyboard among a plurality of virtual keyboards displayed on the screen.

3A through 3B, a plurality of characters may be arranged in each virtual keyboard 300. Each virtual keyboard 300 of FIGS. 3A to 3B represents a three-dimensional virtual keyboard in which a plurality of characters are arranged in a three-dimensional virtual space. The type and shape of the virtual keyboard are one example for describing the disclosed technology, and the shape of the virtual keyboard or the type of characters arranged on the virtual keyboard may vary according to an implementation method. For example, the virtual keyboard may be a virtual keyboard in the shape of a qwerty keyboard as in FIGS. 3A to 3B, or may be a virtual keyboard in the shape of a square, a cube, or a sphere.

3A, 3B and 3C, the mobile terminal 310 includes a display area 320 and an input key 330 including screen touch input means from a user. The user may hold the mobile terminal 310 with the hand 340 and input text through movement.

The display area 320 may include the text input area 322 and one or more virtual keyboards disposed in the virtual space. The virtual keyboards displayed on the display area 320 may be selected by pre-stored setting information, user selection, movement of the mobile terminal 310 and / or attributes of the virtual keyboards. The text input area 322 displays a character selected and input from a specific virtual keyboard 324 among the virtual keyboards through the movement of the mobile terminal 310. The input key 330 is a key for inputting a command to the mobile terminal 310 in addition to the command input through the touch of the display area 320.

4 is a diagram illustrating a mobile terminal displaying a virtual keyboard 324 displayed on a screen and displaying a location in a space of the mobile terminal.

Referring to FIG. 4, the controller 120 may display a pointer 410 indicating a current position of the mobile terminal 310 in the virtual space or the virtual keyboard 324. According to an embodiment, the controller 120 may set whether to display the indicator 410 indicating the current position on the virtual keyboard 324 and the display method of the indicator 410. The controller 120 displays the indicator 410 according to the setting. Since the current position of the mobile terminal 310 in the space may be above the virtual keyboard 324 in the virtual space and sometimes outside the virtual keyboard 324, this state may be represented by the state or shape of the indicator 410. The indicator 410 may move on the virtual keyboard 324 according to the moved position in the space of the mobile terminal 310. The user may check the character selection position on the virtual keyboard through the position or area of the indicator 410. For example, when the indicator 410 is located in a specific area on the virtual keyboard, a letter corresponding to the area may be selected. 4 is one example for describing the disclosed technology, and the type and shape of the indicator 410 may vary according to implementation.

Referring back to FIG. 2, when a program or process for text input is executed, the controller 120 detects the movement of the mobile terminal 310 through the motion detector 110 and outputs a detection result converted into an electrical signal. It is provided from the motion detection unit 110 (step S220).

When the movement of the mobile terminal 310 is detected, the control unit 120 inputs the selected character in the case of character selection of a specific virtual keyboard according to the detected movement (step S230). If the character selected in the virtual keyboard is a command code, the controller 120 may execute a command corresponding to the command code.

Steps S220 and S230 may be repeated while the character input is continued.

5 is a diagram illustrating a movement of a mobile terminal used to determine a character selection position.

Referring to FIG. 5, the controller 120 determines a character selection position by detecting a moving direction of the mobile terminal 310. The mobile terminal 310 may have any movement such as moving in all directions, such as right, left, up, down, and diagonal directions, or tilting and rotating, and the controller 120 may detect the movement of the mobile terminal 310. . When the movement of the mobile terminal 310 is detected, the controller 120 may move the indicator 410 to the moved position of the mobile terminal 310. In another exemplary embodiment, the controller 120 may determine an angle at which the user can best see the display area 320 of the mobile terminal 310 (for example, the line of sight of the user and the surface of the display area 320 may be perpendicular to each other). Angle of the mobile terminal 310 to detect the movement of the mobile terminal 310 to move the indicator 410 on the virtual keyboard.

In an embodiment, the controller 120 may move the indicator 410 in proportion to the moving speed of the mobile terminal 310. For example, when the motion detector 110 provides an electrical signal including a moving direction and a moving speed of the mobile terminal 310, the control unit 120 may move and move the indicator 410 based on the corresponding signal. The speed of movement can be determined.

The movement of the mobile terminal for determining the character selection position by moving the indicator 410 is one example for describing the disclosed technology, and the movement of the mobile terminal for moving the indicator 410 may vary depending on the implementation manner. . For example, the indicator 410 may be moved along a direction in which the mobile terminal 310 is inclined in an arbitrary direction (up, down, left, right).

6A to 6C illustrate a method of arranging the virtual keyboards 300 in a virtual space, a movement of the mobile terminal 310 with respect to the arranged virtual keyboards, and a series of character selection and input processes by the movements. The drawings are as follows.

The method of arranging the virtual keyboards 300 in the virtual space affects the accuracy and speed of the character input in the series of character inputs. In the above drawings, a process for inputting a series of characters 'QWA' in a situation in which two pseudo virtual keyboards 300 are arranged side by side is shown. First, the position of the 'Q' of the virtual keyboard 300 disposed in the virtual space in the pushing direction or the arm extending direction of the mobile terminal 310 to select and input the first input character 'Q'. Alternatively, the mobile terminal 310 is moved to a space corresponding to 'Q' to select and input 'Q'. For example, the mobile terminal 310 may be selected and input by moving the mobile terminal 310 in a push direction or an arm extension direction. In order to input the next input character 'W', the user corresponds to the position or 'W' of the 'W' of the virtual keyboard 300 disposed in the virtual space in the direction of pulling the mobile terminal or bending the arm. Move to a space to select and input 'W', and then move to the direction pushing the mobile terminal 310 again to select and enter 'A'. For example, the mobile terminal 310 may be moved in the direction in which the arm is bent to select and input 'W'. It can be seen that the input according to the method is much more effective in terms of time and effort for input than when one virtual keyboard is placed in the space.

In another embodiment, a virtual keyboard having consonants is arranged on the pushing side (distingly) of the plurality of virtual keyboards arranged in the virtual space and a virtual keyboard having a collection of vowels is arranged on the pulling side of the virtual keyboard. When the terminal 310 moves in the pushing / pull direction, the controller 120 moves or moves the mobile terminal 310 in the virtual keyboard arranged in the space of the pushing direction and the virtual keyboard arranged in the space of the pulling direction. A word corresponding to the letter may be received continuously.

This process can increase the accuracy and efficiency of the text input. In this manner, the order of moving the mobile terminal 310 in the direction of pushing (pushing) or pulling (pull) is one example, and the order may be changed. The virtual keyboards arranged in space may arrange not only virtual keyboards in which the same characters are arranged but also virtual keyboards in which other characters are arranged, for example, an English keyboard and a number / sign keyboard. Furthermore, three or more keyboards can be arranged in a virtual space by forming layers according to depths near or far away from the user, thereby creating an environment suitable for a text input situation. The drawings and the description are examples for describing the disclosed technology, and can be easily applied according to the number of virtual keyboards and an input situation.

In another exemplary embodiment, a specific virtual keyboard may be selected from among the plurality of virtual keyboards 300 according to the moving direction of the mobile terminal 310, and the selected virtual keyboard may be activated to select characters arranged in the virtual keyboard. And the selected character can be entered. The virtual keyboard that is not selected becomes inactive and the characters arranged in the virtual keyboard cannot be selected, and thus the characters cannot be input.

6D to 6F illustrate a process of receiving a character corresponding to the corresponding position or area when the moved position of the mobile terminal 310 is a specific position or a specific area on or passes through the virtual keyboard.

Referring to FIG. 6D, when the moved position of the mobile terminal 310 on the specific virtual keyboard 324 is a position or area corresponding to or passes through a specific character, the controller 120 selects and inputs the corresponding character. . For example, when the moved position 410 or the area of the mobile terminal 310 is a location or area corresponding to the letter 'b', the controller 120 selects 'b' and receives the text and inputs the corresponding letter. Display in area 322.

6E and 6F, the controller 120 may continuously receive text according to a series of movements of the mobile terminal 310. For example, the mobile terminal 310 moves to a location or area corresponding to '(O)' (610a), after leaving the location or area and passes the location or area (610b) corresponding to 'ㅏ', and again the corresponding location After moving out of the area or moving to a position or area 610c corresponding to 'b', the controller 120 may receive the letter 'in'. When the mobile terminal 310 moves outside of the location or area 610c corresponding to 'b' and then moves back to the location or area 610c, the controller 120 may receive 'b' again. have. After receiving 'b' again, the mobile terminal 310 leaves the corresponding location or area, passes the location or area 610d corresponding to 'ㅕ', and leaves the location or area corresponding to 'ㅇ' after leaving the location or area. Alternatively, when moving to the area 610a, the controller 120 may receive the letter 'nyeong'. Therefore, the controller 120 may receive the word 'hello' according to the continuous movement of the mobile terminal 310.

7A to 7D illustrate a process of receiving a character corresponding to a corresponding position or area when a moving direction of the mobile terminal changes in a specific position or a specific area on a virtual keyboard.

7A and 7B, when the mobile terminal 310 moves to the right, the controller 120 moves the indicator 410 to the right on the specific virtual keyboard 324. When the mobile terminal 310 moves downward again, the controller 120 moves the indicator 410 down on the virtual keyboard 324 and corresponds to an area including a position or coordinate where the moving direction of the indicator is changed. Receive a letter. The controller 120 may divide the area of the virtual keyboard 324 to correspond to each letter.

The controller 120 monitors a moving direction of the indicator 410 and receives a character corresponding to an area including a position or coordinate where the moving direction of the indicator is changed. For example, when the moving direction of the indicator 410 differs by a predetermined angle or more based on a specific position or coordinate, the controller 120 may receive a character corresponding to an area including the corresponding position or coordinate.

7C and 7D, the controller 120 may continuously move the indicator 410 according to the movement of the mobile terminal 310 and receive text. For example, the indicator 410 moved to the right after receiving the input of 'ㅇ' moves back to the left in the 'ㅏ' character area, thereby changing the moving direction, and the indicator 410 moved to the left becomes the 'b' character area. If the moving direction is changed again by moving upward from the control unit 120 may receive the letter 'in'. If the moving direction is changed again in the 'b' character area, the controller 120 may receive 'n' again. After receiving 'b' again, the indicator 410 moved in the upper right diagonal direction is moved again in the lower left diagonal direction in the 'ㅕ' character area, and the moving direction is changed, and the indicator 410 moved in the lower left diagonal direction. When the movement direction is changed again by moving downward in the letter area 'O', the controller 120 may receive the letter 'nyeong'. Therefore, the controller 120 may receive the word 'hello' according to the continuous movement of the mobile terminal 310.

FIG. 8 is a diagram illustrating that virtual keyboards of a virtual space, relative spaces of a mobile terminal, and keyboards arranged in the space are maintained while the user is walking or riding a car. That is, the user may continue to input text while maintaining the shape of the current virtual space through the movement of the mobile terminal while moving.

Through the above process, the controller 120 may complete the desired sentence by receiving the selected character on the virtual keyboard. Hereinafter, a process of performing a command corresponding to the movement of the mobile terminal will be described.

When the movement of the mobile terminal 310 is detected, the controller 120 may determine the virtual keyboard or the virtual keyboard based on the detected movement and the current position of the mobile terminal, the type of virtual keyboard, the attributes of the virtual keyboard, and / or the current character selection position. Search for a command corresponding to the detected movement among commands that can be performed at the current character selection position of the keyboard. For example, the controller 120 searches for a command by searching a stored command index based on the detected motion and the type of the virtual keyboard and / or the current character selection position when the current position of the mobile terminal is on the virtual keyboard. The command can be executed by calling the command linked with the index. When the searched command is executed, the controller 120 displays the result of the execution on the display area 320 and, if there is no searched command, maintains the current state.

FIG. 9 is a diagram illustrating a virtual keyboard, a position on a keyboard, and a command index for searching for a command corresponding to a movement of a mobile terminal.

Referring to FIG. 9, the command index 910 lists commands based on the type of virtual keyboard, the current character selection position, and the detected movement. When the current position of the mobile terminal is on the virtual keyboard, the controller 120 may be configured to all of the current virtual keyboard, the character selection position on the virtual keyboard, and the movement of the mobile terminal 310 recognized by the motion detector 110. Matching commands may be retrieved from the command index 910.

In one embodiment, the commands that may be included in the command index 910 include a keyboard change command for changing a currently selected virtual keyboard to another virtual keyboard and / or an associated character input command for receiving a character associated with a character at a current character selection position. It may include.

For example, the Change Keyboard command can change the current virtual keyboard to a virtual keyboard with letters from other languages, the current virtual keyboard to a character keyboard, a numeric keyboard, a sign keyboard, a symbol keyboard, or a keyboard with other characters or characters. Command to change the current virtual keyboard to uppercase or lowercase keyboard, and a command to change the current virtual keyboard to a double consonant or a terminal sound keyboard. The associative character input command converts a character at the current character selection position to uppercase or lowercase, and receives a case conversion command, a command for receiving a consonant string for the character at the current character selection position, and / or a character at the current character selection position. It may include a command for receiving a subscript character.

10 is a diagram illustrating a process of performing a command corresponding to a movement according to a movement of a mobile terminal.

Referring to FIG. 10, when the current virtual keyboard is the Hangul keyboard and the character of the character selection position selected by the indicator 410 on the current virtual keyboard is 'ㄱ', the mobile terminal 310 moves to the left and then returns again. When the movement is detected, the controller 120 may execute a double consonant display command. The controller 120 may display a double consonant 'ㄲ' on the character input area 322 by executing a corresponding command. In an embodiment, the controller 120 may move the indicator 410 or perform a command based on the speed at which the mobile terminal 310 moves. For example, when the mobile terminal 310 moves to the left at a predetermined speed or less and then returns, the controller 120 moves the indicator 410 to the left on the virtual keyboard 324 and then again. You can return to the original position. If the movement of the mobile terminal 310 to the left after moving above a predetermined speed is detected, the controller 120 may search for a command corresponding to the movement and perform the command.

11A and 11B illustrate a process of performing a command for changing a virtual keyboard that is a target of a command according to a movement of a mobile terminal.

Referring to FIGS. 11A and 11B, when the mobile terminal 310 detects two movements after moving to the left, the controller 120 previously displayed a virtual keyboard that is the target of the current command. You can change to keyboard. For example, in the case where the currently selected virtual keyboard is a Korean keyboard and the previous virtual keyboard is a lowercase English keyboard, when the mobile terminal 310 moves to the left after detecting the movement twice in the current virtual keyboard, the controller 120 ) May display a lowercase English keyboard, which is a previous virtual keyboard, on the display area 320.

If the movement of the mobile terminal 310 is detected after changing to the English keyboard, the controller 120 may move the indicator 410 according to the movement to determine a character selection position and receive a character.

12A and 12B illustrate a process of receiving an associated character at a specific position on a virtual keyboard according to the movement of a mobile terminal.

12A and 12B, when a specific movement of the mobile terminal 310 is detected at a specific position of a lowercase English keyboard, which is a virtual keyboard, the controller 120 may receive a character associated with a character at a corresponding position. . For example, when the mobile terminal 310 moves upward and then returns from the letter 'y' of the lowercase English keyboard, the controller 120 receives an uppercase letter Y of the corresponding letter and inputs a character. And display at 322.

When the mobile terminal 310 detects a movement of the mobile terminal 310 after the mobile terminal 310 moves to the right at the letter 'y' of the lowercase English letter, the controller 120 inputs the original character 'ⓨ' of the corresponding character. It can be displayed on the character input area 322.

12A and 12B are examples for describing the disclosed technology, and the movement of the mobile terminal corresponding to the command for displaying the associated text or the type of the associated text may vary depending on the implementation.
