Alternatively, the controller may control the cursor 410 to move when the sensed rotational movement is not less than the predetermined angular velocity, but is greater than or equal to the predetermined angular distance. Alternatively, the controller may control the cursor to move only when the rotational movement is detected regardless of the angular velocity and the angular distance.

As shown in (4-3) of FIG. 4, the rotationally moved mobile terminal 100 is returned to the original terminal position. When the rotationally moved mobile terminal 100 is returned to its original position, the controller 180 may control the cursor 410 not to move.

Accordingly, the terminal user can input the text at the position of the cursor 410 moved to the left.

The cursor 410 is moved in the corresponding direction when the mobile terminal 100 is rotated, and when the mobile terminal 100 returns to its original position, the cursor 410 maintains the moved position . However, the present embodiment is not limited to this, and the cursor 100 is maintained at the original cursor position until the mobile terminal 100 is rotated, and when the mobile terminal 100 returns to its original position, The cursor 410 may be configured to move in the corresponding direction.

Hereinafter, for convenience of explanation, "returning to the original position after being rotated" may simply be expressed as "rotational movement ".

Meanwhile, although not shown, the cursor 410 may be moved to the right when the mobile terminal 100 is rotated in the second rotation direction with respect to the first rotation axis. It will be apparent to those skilled in the art that the same can be implemented with the same principles as described above, so that the detailed description will be omitted for the sake of simplicity.

This will be described below with reference to FIG.

As shown in (5-1) of FIG. 5, a predetermined text is input in the text input window 400. FIG.

The mobile terminal 100 is rotated in the third rotation direction with respect to the second rotation axis, as shown in (5-2) of Fig.

Then, the sensor senses the rotational movement of the mobile terminal 100.

The controller 180 moves the cursor 410 upward by one line according to the detected rotation.

As shown in (5-3) of FIG. 5, the rotationally moved mobile terminal 100 is returned to the original terminal position. When the rotationally moved mobile terminal 100 is returned to its original position, the controller 180 may control the cursor 410 not to move.

Accordingly, the terminal user can input the text at the position of the cursor 410 moved to the left.

(E.g., but not limited to) a cursor movement when rotated at a predetermined angular velocity and / or a predetermined angular distance, and returning to the original terminal position after the rotational movement The above-described text input related function can be performed. Therefore, a detailed description will be omitted. This is the same in the following description.

Meanwhile, although not shown, the cursor 410 may be moved to the lower line when the mobile terminal 100 is rotated in the fourth rotation direction with respect to the second rotation axis. It will be apparent to those skilled in the art that the same can be implemented with the same principles as described above, so that the detailed description will be omitted for the sake of simplicity.

The text input related function is not limited to the movement of the cursor but may be more various. This will be further described with reference to FIG.

As shown in (6-1) of FIG. 6, a predetermined text is input to the text input window 400. FIG. The cursor 410 is displayed on the text input window 400. [

The mobile terminal may be rotated twice (i.e., in a double rotation) twice in the first rotation direction with respect to the first rotation axis. The double rotation movement refers to a first rotation movement in the first rotation direction and a second rotation movement within a predetermined time (for example, 0.5 seconds) after returning to the original terminal position.

Then, as shown in (6-2) of FIG. 6, an enter may be inputted to the corresponding position of the cursor 410. [ An enter symbol 425 may be displayed at the entered enter position so that the terminal user can visually recognize that the enter is entered in the text input window 400. [ If the input text is a message, it should not be transmitted to the other party until the enter symbol 425 even though the message is completed and transmitted to the other party.

In FIG. 4, the cursor 410 is moved by one letter when the mobile terminal 100 is rotated in the first or second rotation direction with respect to the first rotation axis. However, this embodiment is not limited to this. This will be further described with reference to FIG.

As shown in (7-1) of FIG. 7, a predetermined text is input to the text input window 400. FIG. The cursor 410 is displayed on the text input window 400. [ Quot; space "is adjacent to the left side of the cursor 410, and the word" you "

The mobile terminal 100 is rotated in the first rotation direction with respect to the first rotation axis.

Then, as shown in (7-2) of FIG. 7, the cursor 410 is moved to the left beyond the "space ". Therefore, the word "miss" is adjacent to the left side of the cursor 410 and the "space"

The mobile terminal 100 is rotated once more in the first rotation direction with respect to the first rotation axis.

Then, as shown in (7-3) of FIG. 7, the cursor 410 can be moved to the left beyond one alphabet "s" of the word "miss". That is, if there is a word in the direction in which the cursor 410 is to be moved, it can be shifted by one letter each time it is rotated.

Alternatively, as shown in (7-4) of FIG. 7, if there is a word in the direction in which the cursor 410 is to be moved, it can move beyond the entire word "miss" rather than moving by one alphabet .

In the above description, when the mobile terminal 100 is rotated and moved, the cursor 410 is moved or entered as the text input related function. However, this embodiment is not limited thereto. 8 will be further described.

As shown in (8-1) of FIG. 8, a predetermined text is input in the text input window 400. FIG. The cursor 410 is displayed on the text input window 400. [ On the left side of the cursor 410 is the word "your ".

The mobile terminal 100 is first rotated with respect to the first rotation axis.

Then, as shown in (8-2) of FIG. 8, the cursor 410 is moved to the left by one alphabetic digit while the "r" of the word "your" on the left side of the cursor 410 is deleted . That is, the first rotational movement may correspond to a backspace function.

Then, the mobile terminal 100 is moved in the second rotational direction about the first rotational axis.

Then, as shown in (8-3) of FIG. 8, a space is input to the moved alphabet position while the cursor 410 moves to the right by one alphabet position. That is, the second rotational movement can correspond to the space function.

Hereinafter, the space and backspace functions will be described in more detail with reference to FIG.

As shown in (8-1) of FIG. 8, a predetermined text is input in the text input window 400. FIG. The cursor 410 is displayed on the text input window 400. [ On the left side of the cursor 410 is the phrase "misssyou ". The phrase "misssyou" is a typo of "miss you". Hereinafter, a process for correcting the erroneousness of the phrase will be described.

Between "misss" and "you" of the phrase "misssyou" is touched. That is, the desired position is touched to move the cursor 410 to the desired position.

Then, as shown in (8-2) of FIG. 8, the cursor 410 is positioned between "misss" and "you ".

Then, the mobile terminal 100 is rotated in the first rotation direction with respect to the first rotation axis.

Then, the cursor " s "of" misss "is deleted, and the cursor 410 is moved to the left by one alphabetic digit. When the cursor 410 is moved by one alphabetical digit to the left, all the text or "you" located on the right side of the cursor 410 is shifted to the left by one alphabet place. That is, the phrase "misssyou" is converted into "missyou ". Then, the cursor 410 is positioned between "miss" and "you" of the converted phrase "missyou ".

Then, the mobile terminal 100 is rotated in the second rotation direction with respect to the first rotation axis.

Then, the cursor 410 is moved to the right by one alphabet position, and a space is input to the moved alphabet position. When the cursor 410 is moved to the right, all of the text "you" located on the right side of the cursor 410 is shifted to the right by one alphabet position. That is, the phrase "missyou" is converted back to "miss you ". As a result, the correction of the above-described error can be completed.

In FIGS. 8 and 9, the mobile terminal 100 is deleted by one letter each time the mobile terminal 100 is rotated in the first rotation direction. However, this embodiment is not limited to this. 10 will be further described.

As shown in (10-1) of FIG. 10, a predetermined text is input to the text input window 400. FIG. The cursor 410 is displayed on the text input window 400 and a space is displayed on the left side of the cursor 410.

The mobile terminal 100 is first rotated with respect to the first rotation axis.

Then, as shown in (10-2) of FIG. 10, the cursor 410 is moved to the left by one alphabet position while the space on the left side of the cursor 410 is deleted. Therefore, the cursor "you" is adjacent to the cursor 410 on the left side.

The mobile terminal 100 is moved once more for the first rotation axis.

Then, as indicated by (10-3) in FIG. 10, the cursor 410 can be shifted to the left by one alphabetic digit while "u" of the word "you" is deleted. That is, if there is a word in the left direction in which the cursor 410 is to be moved, it can be deleted by one alphabet every time the first rotation movement is performed.

Alternatively, as shown in (10-4) in FIG. 10, when there is a word in the left direction in which the cursor 410 is to be moved, the entire word "you" is deleted instead of shifting by one alphabet, The cursor may move to the left by the number of digits corresponding to the number of the alphabet of the deleted word.

Hereinafter, another text input related function will be described with reference to FIG.

As shown in (11-1) of FIG. 11, a predetermined text is input in the text input window 400. FIG.

The mobile terminal 100 is rotated in the fourth rotation direction with respect to the second rotation axis.

Then, as shown in (11-2) of FIG. 11, an enter may be entered at a position corresponding to the cursor 410. [

The mobile terminal 100 is rotated in the third rotation direction with respect to the second rotation axis.

Then, as shown in (11-3) in FIG. 11, all of the previously input text can be deleted.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

For example, in the above description, the cursor is moved in succession according to the number of times the mobile terminal 100 is rotated, a space or an enter is input, or a previously input text is deleted.

However, the present embodiment is not limited to this, and the cursor may be shifted in succession to the time until the mobile terminal 100 is rotated and moved back to the original terminal position, a space may be input, Can be deleted.

It has also been described that when the mobile terminal 100 is rotationally moved in the first rotational direction, the space is inputted when the previously inputted text is deleted and rotationally moved in the second rotational direction. However, the present embodiment is not limited to this, and it is also possible that the space is inputted when the previously input text is deleted and rotated in the second rotation direction when rotating in the first rotation direction. This also applies to the third rotation direction and the fourth rotation direction. That is, in the above description, the specific text input related function is matched only in the specific rotation direction is merely an example, and other text input related functions may be matched in the specific rotation direction.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . Also, the computer may include a control unit 180 of the terminal.
