Character input method using remote controller {Character input method using remote controller}

One embodiment of the present invention relates to a character input method using a remote controller.

With the development of electronic technology, video display devices equipped with a display panel such as a digital television receiver are connected to the Internet to perform data communication, or input and store a predetermined message, and transmit the stored message to another user. Branch functionality is being added.

As a method of performing the data communication or inputting a predetermined message, there is a method of integrally configuring a keyboard in a remote controller for remotely controlling an operation of an image display device.

However, integrating the keyboard with the remote controller increases the size of the remote controller and puts a lot of economic burden on the user at high cost.

Therefore, in recent years, an on-screen keyboard is displayed on the display panel of an image display device, and the cursor is positioned on the on-screen keyboard displayed on the display panel by selecting while moving the cursor with the direction key provided in the remote controller. Screen keyboard methods for entering characters are widely used.

However, the screen keyboard method requires a user to select and then place a cursor at a position of a character to be input by manipulating a direction key one by one, which gives the user a lot of trouble and inconvenience, and also takes a lot of time to input characters. There are several problems.

As another method of inputting characters, a plurality of consonants and vowels corresponding to each key on the remote controller are printed on the keys on the remote controller, and the keys corresponding to the consonants and vowels that the user wants to input are printed based on the printed characters. There is a way to input selectively. However, such a method has a problem in that a quick key input is not easy because the position of a key corresponding to a character to be input by the user must be identified by the contents printed on the key.

An embodiment of the present invention provides a character input method using a remote controller that can reduce the number of key inputs compared to the existing input method, and also provide the enjoyment of input by variously changing the shape of the on-screen keyboard.

The present invention provides a method for inputting characters into a display device using a remote controller, the method comprising: displaying an on-screen keyboard including a plurality of characters on the display device; Defining characters displayed on the on-screen keyboard into a plurality of groups, and moving the selected character group according to the direction key manipulation signal of the remote controller to display the character group; Rearranging and displaying characters of the selected character group according to a selection key operation signal of the remote controller; And displaying and inputting a selected character among the rearranged characters according to a direction key manipulation signal of the remote controller.

In the displaying of the on-screen keyboard, a plurality of characters displayed on the display device may be a Korean consonant, a Korean vowel, an English alphabet uppercase letter, an English alphabet lowercase letter, Japanese, Chinese, Russian, Indian, or Western European. In addition, the on-screen keyboard may display all the characters of the world, but the present invention is not limited thereto.

After displaying and entering the text, the display may return to displaying the character group.

Defining the letters into a plurality of groups may be defined as one group of one to four letters arranged in the horizontal direction.

The direction keys may be arranged in four directions of up, down, left, and right, and the selection key may be located at the center of an area formed by the direction keys.

The rearranging and displaying the characters may be performed by allocating characters or characters of the selected character group to one to four directions of up, down, left and right, respectively. The displaying and inputting of the selected characters among the rearranged characters according to the direction key manipulation signal may display and input a character corresponding to the direction key.

An embodiment of the present invention provides a character input method using a remote controller that can reduce the number of key inputs compared to the existing input method, and also provide the enjoyment of input by variously changing the shape of the on-screen keyboard.

In addition, the on-screen keyboard driver 203 also displays a display window 220 displaying characters input on one side.

The group mode activator 204 is activated simultaneously with or after the operation of the on-screen keyboard driver 203. That is, the group mode activator 204 defines one to four characters as one group and displays them with relative emphasis. For example, one character group may mean 1 to 4 characters arranged in the horizontal direction. More specifically, in the QWERTY keyboard, "ㅂㅈㄷㄱ" may be defined as one character group, and the selected one character group may be highlighted in comparison with other character groups. Here, highlighting means displaying relatively brighter, boxed or flickering.

Of course, one character group may mean 1 to 4 characters listed in the vertical direction instead of the horizontal direction. More specifically, in the QWERTY keyboard, "ㅂㅁㅋ" may be defined as one character group, and the selected one character group may be displayed with emphasis compared to other character groups.

The direction key signal determination unit 205 analyzes an operation signal of the direction key 101 provided in the remote controller 100 to display a corresponding character group to the user. In addition, the direction key signal determination unit 205 analyzes an operation signal of the direction key 101 to select, display, and input a specific character corresponding thereto. To this end, the direction key signal determination unit 205 uses the data obtained from the character group storage unit 205a or uses the data obtained from the rearranged character storage unit 205b. This will be described in detail later.

As described above, when the direction key signal determination unit 205 recognizes the operation signal of the direction key 101, the direction key corresponding character group moving unit 206 moves in the corresponding direction to display the character group. For example, when the user presses a right key among the direction keys 101 of the remote controller 100, the character group located on the right side of the character group displayed on the on-screen keyboard 210 is highlighted.

The selection key signal determination unit 207 analyzes an operation signal of the selection key 102 included in the remote controller 100 to display a character corresponding thereto. That is, the selection key signal determination unit 207 causes the character rearrangement and input mode activation unit 208 to operate when an operation signal of the selection key 102 is input. In addition, the selection key signal determination unit 207 may cause the group mode activation unit 204 to operate when an operation signal of the selection key 102 is input.

When the selection key signal determination unit 207 determines that the signal is input from the selection key 102, the character rearrangement and input mode activation unit 208 rearranges the characters defined or assigned to the selected group in a predetermined form. To the user. In addition, when it is determined that the direction key 101 signal is input from the direction key signal determination unit 205 included in the remote controller 100 in this state, a specific character among the rearranged characters corresponding to the direction key 101 is input. Allows you to select, display and enter

As described above, since such components may be implemented in hardware or in software (or program), the present invention should not be limited to the aforementioned components. As an example, since the implementation of the present invention may be implemented in software in various methods and languages, specific components of the above-described components (or programs) may be excluded or other components may be implemented in addition to the above-described components. Can be. This will become clearer through the description of the character input method according to the present invention to be described below.

2A and 2B are diagrams for describing a group mode and an input mode in the on-screen keyboard, respectively.

As shown in FIG. 2A, the on-screen keyboard 210 displayed on the display device 200 displays a plurality of numbers, Hangul consonants, Hangul vowels, or special keys. 211). For example, in the QWERTY keyboard, "ㅂㅈㄷㄱ", "ㅁㄴㅇㄹ", "ㅋㅌ ㅊㄷ", etc. may form one character group 211, respectively.

As shown in FIG. 2B, in the character rearrangement state 212, characters of any one selected character group are rearranged in four directions of up, down, left, and right, respectively. For example, in the character group "ㅂㅈㄷㄱ", "ㅂ" is arranged on the leftmost side, "ㅈ" is arranged on the topmost side, "c" is arranged on the rightmost side, and "ㄱ" is arranged on the bottommost display. do. In this case, all remaining character groups or characters may be displayed in gray, and only the letters in the four directions may be highlighted.

3 is a flowchart illustrating a character input method using a remote controller according to an embodiment of the present invention.

As shown in FIG. 3, the character input method according to the present invention includes an on-screen keyboard activation determination step S1, an on-screen keyboard activation step S2, a group mode activation step S3, and a direction key signal reception determination step ( S4), direction key corresponding character group moving step (S5), selection key signal reception determination step (S6), character rearrangement and input mode activation step (S7), direction key signal input determination step (S8), direction key corresponding character An input step S9, an on-screen keyboard deactivation determination step S10, an on-screen keyboard deactivation step S11, and a selection key signal reception determination step S12 are included.

Although the steps are described in time series in the present invention, the character input method according to the present invention is not limited to the time series order. For example, if the user deactivates the on-screen keyboard 210 by operating a specific key of the remote controller 100 at any step, the character input method according to the present invention is stopped or cancelled. In addition, although steps S4 and S5 are shown in the figure as step S6 is performed, in some cases step S6 may be performed immediately after step S3 is performed.

4A to 4S illustrate an example of a character input method using a remote controller according to an embodiment of the present invention. Here, the character input method according to the present invention will be described with reference to FIGS. 3 and 4A to 4S. In addition, as an example, a method of inputting “strong” is described as an example, and for the purpose of understanding the present invention, the direction key 101 and the selection key (1) are provided on one side of the on-screen keyboard 210 displayed on the display device 200. Also shown is a remote controller 100 that includes 102. In addition, it is to be noted that the subject of control is hardware (for example, microcomputer) or software (program) installed in the display device 200.

First, in the on-screen keyboard activation determination step (S1), it is determined whether the user presses a specific key of the remote controller 100 to activate the on-screen keyboard 210 on the display device 200.

If it is determined in step S1 that the on-screen keyboard 210 is activated, as shown in FIG. 4A, the on-screen keyboard activation step S2 is performed. That is, the on-screen keyboard 210 having a plurality of characters is displayed on the display device 200. As shown in the drawing, an upper side of the on-screen keyboard 210 may be provided with a display window 220 in which characters are displayed and input.

In addition, as shown in FIG. 4A, in the group mode activation step S3, a plurality of characters may be grouped (defined) into one group 211 to be highlighted and displayed to the user.

Meanwhile, the user may perform steps S4 and S5 and perform step S6, but may optionally perform step S6. That is, in the case of inputting any one of the characters in the first character group (ㅂ, ㅈ, c, ㄱ) 211 in the on-screen keyboard 210, steps S4 and S5 are omitted, and step S6 is performed immediately.

As shown in Fig. 4B, in the selection key signal reception determination step S6, it is determined whether the user has operated the selection key 102 in the remote controller 100.

As shown in FIG. 4B and FIG. 4C, in the character rearrangement and input mode activating step S7, each of the four characters forming the character group is rearranged in four directions of up, down, left, and right directions 212, respectively. And display. At this time, the remaining characters are displayed in the mode opaque, so that only the letters arranged in the four directions are emphasized.

More specifically, it may be rearranged by allocating "a" in the left direction, "" "in the upper direction," c "in the right direction, and" a "in the lower direction. Of course, such a rearrangement allocation scheme is merely an example, and characters may be rearranged in a manner different from that described herein.

As shown in FIG. 4D, in the character input step S8 for direction key, it is determined whether the user has operated the specific direction key 101 in the remote controller 100.

In addition, as shown in FIG. 4D, when the user manipulates the specific direction key 101, a character corresponding to the selected direction is selected and displayed and simultaneously input. For example, if the user has operated the direction key 101 at the bottom of the remote controller 100 shown in Fig. 4D, the user selects and displays "a" at the same time. That is, it displays and enters "ㄱ" in the display window.

On the other hand, if the user has not operated the direction key here, step S12 may be performed. That is, the selection key signal reception determination step S12 is performed. If it is determined in the selection key signal reception determination step S12 that the user has operated the selection key 102, the group mode activation step S3 is performed. In addition, if it is determined in the selection key signal reception determination step S12 that the user does not operate the selection key 102, the on-screen keyboard deactivation determination step S10 is performed.

Therefore, when the user changes the character to be input in the direction key signal input determination step SS8 or if it is determined that the character to be input is found incorrectly, the user operates the selection key instead of the direction key to activate the character rearrangement and the input mode. Step S7 may be exited and restarted from the group mode activation step S3.

In addition, if the user has not executed the on-screen keyboard deactivation determination step S9 by operating a specific key of the remote controller 100, the process returns to the group mode activation step S3 immediately as shown in FIG. 4E. That is, the character group 211 that was selected first is highlighted.

As shown in Fig. 4F, in the direction key signal reception determination step S4, an operation signal of the direction key 101 operated by the user is received. For example, it is assumed that the rightmost direction key 101 of the direction keys 101 has been operated.

Then, as shown in FIG. 4G, the character group moving step S5 corresponding to the direction key 101 is performed. In this step S5, for example, the character group 213 enclosed by " sq " is highlighted.

In addition, since "ㅏ" should be input, as shown in FIG. 4H, when the user operates the lowermost direction key 101 among the direction keys 101 again, as shown in FIG. 4I, an example is shown. For example, the group of characters 214 enclosed in "ㅎ ㅗㅓㅏ" is highlighted.

As shown in FIG. 4J, in the selection key signal reception determination step S6, it is determined whether the user has operated the selection key 102 in the remote controller 100.

As shown in FIG. 4K, in the character rearrangement and input mode activation step S7, four characters constituting the character group are arranged 215 in four directions of up, down, left, and right directions, respectively. In this case, all remaining characters are opaquely displayed so that only the letters arranged in the four directions are emphasized.

More specifically, the rearrangement may be performed by allocating "ㅎ" in the left direction, "ㅗ" in the upper direction, "ㅓ" in the right direction, and "ㅏ" in the lower direction. Of course, such a rearrangement allocation scheme is merely an example, and characters may be rearranged in a manner different from that described herein.

As shown in Fig. 4I, in the direction key corresponding character input step S8, it is determined whether the user has operated the specific direction key 101 in the remote controller 100.

In addition, as shown in FIGS. 4I and 4M, when the user operates the specific direction key 101, the corresponding character is displayed and input at the same time. For example, if the user has operated the lowermost direction key 101 in Fig. 4I, the user selects and displays "ㅏ" and inputs it at the same time. Therefore, the input of the letter "a" is completed on the display window 220 of the on-screen keyboard 210.

Meanwhile, as illustrated in FIGS. 4N to 4S, the above-described method may be repeated to finally select, display, and input the word “strong”.

In addition, after all of the character input is completed, when a specific time elapses or when a specific key in the remote controller 100 is operated by the user, the on-screen keyboard inactivity determination step S9 and the on-screen keyboard 210 are performed. An inactive step S10 is performed. Then, the on-screen keyboard 210 of the display device 200 disappears and the character input is completely terminated.

In this way, the character input method using the remote controller 100 according to the present invention can significantly reduce the number of key inputs compared to the conventional input method. Substantially, when the existing number of key inputs is 100%, the number of key inputs according to the present invention is reduced by approximately 50 to 75%.

In addition, in the character input method using the remote controller 100 according to the present invention, the screen is frequently changed in the on-screen keyboard 210, and thus the enjoyment of the character input may be obtained.

What has been described above is only one embodiment for implementing the character input method using the remote controller according to the present invention, the present invention is not limited to the above embodiment, as claimed in the following claims Without departing from the gist of the invention, anyone of ordinary skill in the art to which the present invention will have the technical spirit of the present invention to the extent that various modifications can be made.
