The same may be applied to the device will be more apparent through the following description.

1 and 2 are views showing a mobile communication terminal having a scroll button according to a preferred embodiment of the present invention, Figure 3 is a side view of the scroll button of the mobile communication terminal according to an embodiment of the present invention from the side to be.

Referring to FIG. 1, a scroll button 110 may be formed at one side where a function button (for example, a melody button, a message button, a phone number search button, etc.) of the mobile communication terminal 100 is located. Can be. The scroll button 110 may be formed in a wheel shape similar to a scroll formed on one side of a mouse connected to the computer, but is preferably formed in a cylindrical shape that can be smoothly rotated using a finger. In addition, as shown in FIG. 2, the scroll button 110 is preferably formed so that some of the scroll buttons are more protruded to the outside than other buttons so as to easily rotate by touching a finger.

In addition, the scroll button 110 is preferably formed to have a suitable friction force to rotate by touching or pulling the finger. That is, the scroll button 110 may be formed of a material having a good friction force, or may be formed to have a bend as shown in FIG. 3. As shown in FIG. 3, the mobile communication terminal 100 as well as the user may sense the exact amount of rotation of the scroll button 110 as it is formed to have a bend. Rotation of the scroll button 110 may be sensed by a sensor (not shown) connected to the central axis 111 of the scroll button 110. Alternatively, the sensor may include a separate sensor contacting the sawtooth of the scroll button 110 to detect rotation, and in the related art, a method of detecting rotation, such as scrolling of a mouse, is used to detect rotation of the scroll button 110. Obviously, all other methods can be applied equally.

Here, the rotation of the sawtooth of the scroll button 110 can be set in units of rotation. For example, if there are three rotations of the sawtooth of the scroll button 110, it can be recognized as three rotations. Of course, if the scroll button 110 is rotated by a certain angle (for example, 15 degrees) it can be recognized as a single rotation. In this case, it is preferable that the user is formed to feel a jam every time the rotation can be sensed by the user.

In addition, as shown in the figure, when the scroll button 110 is pressed using a finger or the like, it may be pressed by a predetermined depth (for example, 1 mm). That is, the scroll button 110 may not only rotate but also perform a function as a button having a specific function like other buttons such as a call button, an end button, and the like. Of course, the vertical linkage for the scroll button 110 is pressed may be formed to be performed differently from the other buttons.

Hereinafter, a method of inputting numbers, letters, or the like or searching phone number information using the scroll button 110 in the mobile communication terminal 100 according to the present invention will be described.

4 and 5 are exemplary diagrams illustrating a UI screen according to an example of using a scroll button in a mobile communication terminal according to an exemplary embodiment of the present invention.

In the present embodiment, it is assumed that the scroll button 110 is operated when the mobile communication terminal 100 is powered on (initial state). Also, in the initial state, since a number is input when a key button is pressed, it is assumed that the initial state is a number input mode. Of course, when the phone in the text input mode, it is natural that characters may be input.

In the initial state as shown by reference numeral 410, numbers are displayed according to the operation of the scroll button 110 (i.e., pressing or rotating the scroll button 110) from the user. It is preferable to set so that "0" is displayed depending on the operation of the first scroll button 110. Of course, when the user rotates the scroll button 110 one time (for example, one tooth-shaped rotation as shown in FIG. 3), and when two or more rotations are performed, the corresponding number is Naturally, it may be displayed. For example, when the scroll button 110 is rotated once, the number "0" is displayed, and when rotated one more time, the number is changed to "1", and when rotated once more (three times in total), the number is displayed. The display changes to "2". That is, each time the scroll button 110 is rotated once, the corresponding number is displayed. Of course, when the rotation of the scroll button 110 is made a plurality of times within a fast time (for example, 0.1 second), only the number corresponding to the number of rotations may be displayed. For example, when three rotations are performed at high speed while the number "0" is displayed, only "3" may be displayed without displaying "1" and "2".

Here, the mobile communication terminal 100 preferably provides a user interface so that the size of the number displayed on the screen can be set by the user. Therefore, people with dim eyes, such as the elderly, may feel convenient to input the numbers by increasing the size of the displayed numbers.

After the operation of the first scroll button 110, when the scroll button 110 is rotated once by the user's operation, a corresponding number is displayed (reference numeral 420). Here, the displayed number may vary according to the rotation direction of the scroll button 110. When rotating in the downward direction, the number "1" after "0" is displayed, and when rotating in the upward direction, the previous number (for example, "9", or 0, if 0 to 9 can be entered). "99") may be displayed if the input is from 99 to 99. Hereinafter, for convenience of description, the rotation in the downward direction will be referred to as plus rotation, and the rotation in the upward direction will be referred to as negative rotation. Therefore, in the case of the reference numeral 420, the scroll button 110 is rotated once plus. Here, if the user wants to input "0" again, a negative rotation may be performed once to search for "0" and input it.

In this state, when the user presses the scroll button 110, a corresponding number (the number displayed on the screen, that is, "1") is input. Alternatively, if there is no separate operation for a predetermined time (for example, 3 seconds) after the rotation operation of the scroll button 110, the number displayed on the screen may be input without the pressing operation of the scroll button 110. Afterwards, if the two-plus rotation is performed again, an input processed number and a number to be input (that is, a number retrieved according to two rotations of the scroll button 110) are displayed (reference number 430-1 or reference number 430-2).

Accordingly, the user may first check and input the number to be input according to the rotation operation of the scroll button 110 through the screen. Therefore, as described above, a large number is displayed on the screen before input so that users who are not easily seen, such as elderly people, can solve the inconvenience of inputting the number through a button.

Here, in another embodiment, not only the number corresponding to the rotation operation of the scroll button 110 is displayed, but the phone number information according to the shortcut number of the phone book corresponding to the number, such as reference number 420 and reference number 430-2. May be displayed together. Therefore, the user may search for a shortcut number in the phone book according to the rotation operation of the scroll button 110 and press and hold the scroll button 110 (shortcut function) to attempt a call with a phone number corresponding to the retrieved shortcut number ( 430-3). In this case, the speed dial number is an embodiment of searching for phone number information, and any shortcut number may be applicable to any type of search information such as an index for searching phone number information such as a group number and a user specified number. Hereinafter, for convenience of description, a shortcut number will be described as an example of search information of telephone number information according to the present invention.

Reference numeral 430-1 in the drawing indicates an embodiment in which a shortcut number search is not performed when a number is input, and reference numeral 430-2 illustrates another embodiment in which a shortcut number search is performed up to three digits. Of course, two or four digits and more can also search for shortcut numbers together.

In another embodiment, the number corresponding to the rotation of the scroll button 110 may be displayed, and the corresponding phone number information may be displayed by searching only the shortcut numbers. In this case, the phonebook searches for shortcut numbers registered in advance by the user corresponding to the rotation operation (ie, the number of rotations) of the scroll button 110.

Referring to FIG. 5, when the scroll button 110 is rotated once or once in the initial state (reference number 510), telephone number information corresponding to the number “0” and the shortcut number 0 is displayed (reference number 520). Here, the number "0" may not be displayed. Alternatively, numbers 0 to 9 may be displayed together, and numbers 10 or more may not be displayed.

Thereafter, when the scroll button 110 is rotated a predetermined number of times (for example, 17 times), phone number information corresponding to the corresponding speed dial number is displayed (reference number 530-1 and reference number 530-2).

Here, reference numerals 530-1 and 530-2 are according to different embodiments, and only display phone number information according to a speed dial number corresponding to the corresponding number (“17”) (reference numeral 530-1). ), And for displaying the phone number information according to the speed dial number around the number (for example, 15 to 19, which is up and down 2) (reference number 530-2). In this case, when the scroll button 110 is pressed (in this case, only the phone number information is displayed, there is no need to press and hold the button, and of course, it may be set to be pressed for a long time). .

As another example, if the user wants to search the telephone number information registered as the speed dial 70 while the speed dial is registered up to 90, the scroll button 110 may be rotated 21 times with negative rotation. That is, the phone number information according to the speed dial number is searched in the order of 0, 90, 89, ..., 70.

It is apparent that a method similar to the above may be used to search for and input characters such as English and Korean, or to search phone number information using characters in the phone book. For example, if you want to search for a phone number corresponding to "Hong Gil-dong", when entering "hong" using the scroll button, the phone number information of the name including "hong" is searched and displayed on the screen, The phone number information according to "Hong Gil-dong" can be searched. That is, when the preset character conversion button (for example, the "#" button) is pressed once, the Korean language input mode is entered and the Korean language may be searched or input through the scroll button 110. In another embodiment, when the scroll button 110 is negatively rotated, a character may be searched and inputted, and when the scroll button 110 is positively rotated, a number may be searched and inputted. Of course, it may be set in the opposite direction. Therefore, by performing a negative rotation, the phone number information to be searched can be searched by searching and entering text.

It is obvious that other characters such as English, Japanese, and Chinese can be input and searched in the same way as the Korean input method. Alternatively, a plurality of scroll buttons 110 may be provided to input and search numerals and characters (or character types such as English or Korean) using separate scroll buttons 110. Since the character input method and the search method may be performed similarly or identically to the number input and search method, the detailed description thereof will be omitted.

In addition, the scroll button 110 may be used to search for specific information in addition to searching for numbers, letters, and phone number information. For example, pressing a menu button and rotating the scroll button 110 can easily search for a menu item to be selected. It will be apparent through the foregoing description that various scrolling functions may be performed using the scroll button 110. In addition to the search function, the scroll button 110 may also perform a function such as a direction button such as call volume control and screen movement.

As described above, according to the present invention, since not only numbers but also letters can be input using the scroll button 110, a display device such as another LCD module is provided at a position of an existing keypad, thereby providing dual. ) May provide an effect that is easy to implement a screen. Therefore, since the numbers or letters can be input using the scroll button 110, by removing the keypad and providing the display device at the position, two operations can be performed simultaneously using the two screens. For example, you may send a text message using another screen while watching a movie on one screen. Here, it is preferable that another screen provided at the existing keypad position is equipped with a touch screen function so that numbers and letters can also be input by a button method. Since the touch screen function and the dual screen function may be obvious to those skilled in the art since the technology is also used in the related art, detailed descriptions thereof will be omitted.

6 is a functional block diagram showing a configuration according to a function of a mobile communication terminal having a scroll button according to an embodiment of the present invention, Figure 7 is a scroll button in a mobile communication terminal according to an embodiment of the present invention It is a figure which shows the processing process by operation.

As shown in FIG. 6, the mobile communication terminal 100 having the scroll button 110 includes an operation sensing unit 10, a storage unit 20, a search unit 30, an output unit 40, and a control unit ( 50).

The operation detecting unit 10 detects an operation (rotation and pressing) of the scroll button 110. The controller 50 that recognizes the number corresponding to the rotation of the scroll button 110 recognized by the manipulation detecting unit 10 may output the recognized number to the output unit 40 (for example, a display device such as an LCD). The display unit is controlled to display, and then inputs the recognized number according to the pressing of the scroll button 110 recognized by the manipulation detection unit 10. The search unit 30 searches for a shortcut number of the phone book stored in the storage unit 20 corresponding to the recognized number, and the phone number information corresponding to the retrieved shortcut number is displayed by the output unit 40.

In particular, the controller 50 determines whether the current mode is a numeric input mode, a text input mode, or a search mode, and rotates the scroll button 110 recognized by the manipulation detector 10 in correspondence with the current mode. The data corresponding to the operation is output through the output unit 40. For example, the number and phone number information is output in the numeric input mode, and the corresponding menu is output in the search mode such as menu search.

Similarly, the controller processes the input in the same manner according to the pressing operation of the scroll button 110. In addition, the control unit 50 is a call performing unit (not shown, mobile communication system of the mobile communication terminal 100) to attempt to call the phone number of the retrieved phone number information when the pressing of the scroll button 110 exceeds a predetermined time Control calls). Of course, when only the phone number information is displayed by the output unit 40, the control unit 50 attempts to call the corresponding phone number according to the pressing of the scroll button 110 (not determining whether it exceeds a predetermined time). You may.

Hereinafter, a process of searching for phone number information according to a number input or a speed dial number using the scroll button 110 in an initial state will be described.

Referring to FIG. 4 along with FIG. 4, in an initial state, the mobile communication terminal 100 recognizes one rotation or pressing of the scroll button 110 in steps 710 and 720, and registers a shortcut number as “0” in advance. Search the phone number information and display it with the number "0". The phone number information and the numbers may be displayed on the divided screens, respectively, or may be divided and displayed in a predetermined area of the same screen as shown in FIGS. 4 and 5.

In operation 730, it is determined whether a termination command is input. In other words, it is determined whether an end command is input in accordance with the end button operation and the number input is terminated, and the process is processed accordingly. When an end command according to the end button operation is input, it may be set to an initial state again. In step 740, it is determined whether a call command is input. That is, according to the input of the call button, it is determined whether the call attempt command is input by using the currently input number as the phone number and processes accordingly.

In operation 750, it is determined whether the subsequent manipulation of the scroll button 110 is rotation or pressing.

As a result of the determination, when the manipulation of the scroll button 110 is rotation, the number corresponding to the rotation and the telephone number information corresponding to the rotation are displayed and the process proceeds to step 730 (step 760).

As a result of the determination, if it is pressed, it is determined whether there is a registered shortcut number corresponding to the number currently being output (770), and if not, the flow proceeds to step 790. If there is a registered shortcut number, it is determined whether the pressed time exceeds a preset predetermined time (for example, 2 seconds) (step 780). If it is not exceeded, the process outputs the number ("0") currently being output in step 790 and proceeds to step 730. If the predetermined time is exceeded, a shortcut key function is attempted to call the telephone number according to the telephone number information corresponding to the number (step 795).

8 is a diagram illustrating a mobile communication terminal having a plurality of scroll buttons according to another exemplary embodiment of the present invention.

In the mobile communication terminal 100 of FIG. 8, a keypad 120 is formed of twelve scroll buttons. Of course, only a part of the twelve (for example, ten numbers according to 0 to 9) may be formed as scroll buttons. In addition, as shown in the figure, the aforementioned separate scroll button 110 may be provided together.

The mobile communication terminal 100 according to FIG. 8 may easily input characters such as numbers, Korean, and English using respective scroll buttons of the keypad 120. That is, it is possible to easily input not only numbers but also Korean and English only by rotating and / or pressing each scroll button of the keypad 120 without any other button manipulation for mode switching.

For example, if the scroll button corresponding to the number 1 is rotated once and pressed, the number "1" is input, and if rotated and pressed three times, the Korean character "B" is input, rotated five times and the alphabet "A" is pressed. Input is processed. Here, the distinction between the uppercase and lowercase letters of the alphabet may be set to be input differently according to the number of rotation operations of the scroll button. For example, a lower case letter may be input when rotating after an upper case letter.

In another embodiment, when a number is input, the scroll button is only pressed without rotating, and in order to input Korean or alphabet, the scroll button is rotated and pressed. Of course, an input mode setting button for distinguishing between Korean and alphabet input may be provided separately. That is, only Korean characters are input in the Korean input mode and only alphabet characters are input in the English input mode.

In addition, when using different scroll buttons for continuous character input for the convenience of inputting Korean or alphabet, pressing of the scroll button may be omitted. For example, assuming the Korean input mode, when the scroll button corresponding to the number "1" is rotated three times and the scroll button corresponding to the number "6" is rotated one time, "ㄷ" + "ㅏ" "D" is entered. Accordingly, the input speed can be increased without performing the pressing operation of the scroll button.

In another embodiment, not all buttons of the keypad 120 are formed as scroll buttons, but only buttons corresponding to some numbers (for example, the numbers “1”, “2”, and “3”) are formed as scroll buttons. You may. For example, a scroll button corresponding to the number "1" may search and input a consonant of Korean characters, and a scroll button corresponding to the number "2" may search and input a vowel of Korean characters. Scroll buttons corresponding to 3 "can search and enter alphabets. Of course, the button corresponding to the number "4" may be formed as a scroll button, and may be set to an uppercase alphabet, or may be set as a separate character such as Chinese. That is, the type of characters that can be searched and input can be set differently for each scroll button corresponding to each number.

4 and 5, it will be apparent from the foregoing description that numbers or letters corresponding to the rotation manipulation of the scroll button may be displayed on the screen before the input process.

The method of the present invention as described above may be implemented in a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.
