Description

Method for Inputting Characters to Display Device by Character Input Means}

The present invention relates to a method for inputting characters into a display device through character input means capable of inputting one or more characters with one button.

TV has traditionally been a one-way transmission medium that outputs a signal transmitted from a broadcasting station as a video signal. However, with the development and dissemination of the Internet, the concept of TV has changed. Various interactive services through the TV will be made. In other words, various commercial activities such as banking, securities, and home shopping are possible through interactive services through TV.

Since these two-way service is accompanied by financial transactions, authentication is performed through a password for the safety of financial transactions. Also, by law, passwords are strictly restricted from disclosure. That is, by default, all passwords are strictly restricted from being exposed to others. Many examples of this can be seen in the world around us. For example, the password that you enter when you log in to a specific site that you are registered with is replaced by '*' or certain characters so that not only others but also you can see it. This restriction applies equally to TV.

However, there is a problem in that a TV is easily exposed to a person other than the person due to the characteristics of the display device. In addition, unlike a computer, a convenient input means such as a keyboard is not separately installed, and a general TV input means is made through a remote controller. Recently, a technology that uses a wired keyboard to connect to a set-top box and utilizes it as an information input device has been commercialized, and a number of input devices to replace the current remote control are expected to be developed in the future, but the remote control is mainstream.

There is no separate character button on the remote, but a number button. The number button is a typical use of the channel selection function, but it is also used as a means to input various information. In particular, with the numeric buttons, you can enter Korean, English, lowercase letters, special characters, etc. in addition to numbers. This is possible because a plurality of Korean or English characters can be input in one numeric button.

When a button (key) represents a single character, such as a computer keyboard, there is almost no confusion for the user's input characters, except for mistakes made during input. You know most of the characters you typed, even if you display them alternately. This is because a button has a characteristic that represents a single character, so there is no problem in entering a password, and the user is less confused.

However, the TV remote control is assigned a specific button to represent each digit from 0 to 9. In this case, there is no problem in entering a password consisting of only numbers, and there is little concern about chaos. However, if you enter a character such as English characters may cause problems.

You can enter 2 ~ 4 letters (depending on remote control or mobile phone) with one specific number button on the remote control. That is, the input character is determined by how many times the same button is pressed. In this case, alphabetic input also has no problem with normal exposure input. However, the problem arises when you need to enter a password with limited exposure.

In other words, since it is not easy to input the correct alphabetic characters because it is not easy to check the characters currently being input, it is difficult for the inputter to know what characters are selected by pressing the current number of times.

On the other hand, the buttons of the portable terminal are usually printed with a large number commonly used, and a plurality of alphabetic characters that can be input by using the number button is printed per button. Therefore, the above-described problem may occur when inputting characters not displayed such as a password. In the present specification, the term "portable terminal" means a portable terminal including a button for inputting a number or a letter and a display window for displaying the number or letter inputted by the button, and for a mobile communication terminal, a PDA, and an MP3. It refers to any terminal that can be carried, regardless of its kind, such as a player.

The present invention is to solve the problems of the prior art as described above, when the input means is a button of a remote control or a portable terminal is not easy to input, the character inputs a non-numeric characters to the TV or portable terminal It is an object of the present invention to provide a method for easily recognizing input characters when necessary. In addition, an object of the present invention is to provide a method for increasing security in inputting an important number that can be easily recognized by an inputter and require confidentiality such as a password.

The present invention has the following solution means to achieve the above technical problem.

According to the present invention, a method for inputting a character into a display apparatus through a character input means provided with a plurality of buttons capable of inputting one or more characters,

(1) When the first button, which is any number button among the plurality of buttons, is pressed, a pop-up window is created on the screen of the display apparatus, in which at least as many grids as the number of characters inputtable by the first button are arranged in sequence. Generating a pop-up window in which the first grating disposed at one side end of the gratings is changed into a different color or shape so as to be distinguished from the other gratings;

(2) By repeatedly pressing the first button, the number of times that the first button is pressed is changed into a color or a shape so that the grids are sequentially distinguished from other grids from one side of the first grid, and the number of times that the first button is pressed is changed to the number of grids. A character selection step of changing the color or shape from the first grid again if the number exceeds the number;

(3) a character input step of inputting a character corresponding to the number of times the first button is pressed when the confirmation button is pressed among the plurality of buttons, and extinguishing the pop-up window.

According to a preferred embodiment of the present invention, when a second button different from the first button is pressed, a character corresponding to the number of times the first button is pressed is input, and a first grid disposed at one end of the pop-up window is input. It will be changed to a different color or shape to distinguish it from the rest of the grid. The character input step according to the present invention further includes a button change step of recognizing the second button as the first button and performing the character selection step again.

The character input method according to another preferred embodiment of the present invention further includes an input stopping step of pressing a cancel button of the plurality of buttons to stop character input and dissipate the popup window.

It is preferable that the character input by pressing the button is an English letter.

According to another preferred embodiment of the present invention, generating a selection window including a grid for selecting Korean, numerals, and English characters on the display device screen, and generating the pop-up window only when selecting English characters from the selection window. It includes more.

In addition, the pop-up window preferably further includes a grid for selecting the uppercase and lowercase letters.

The text input means may be a remote controller, and the display apparatus may be a TV to which text is input by receiving a signal from the remote controller.

Alternatively, the character input means may be a button of a portable terminal, and the display apparatus may be a portable terminal provided with a display window.

Alternatively, the character input means may be a button of a portable terminal, and the display apparatus may be a portable terminal provided with a display window.

The present invention has the following effects by the problem solving means as described above.

In the present invention, what is displayed on the screen simply changes the color of the grid so that a person other than the inputter cannot know which character is selected. Therefore, the present invention has the effect that the characters used in the password is not exposed. However, in the present invention, since the inputter can know the number buttons that he or she is pressing, the user can know how many letters are currently selected from each number button, and thus the character used for the password can be confirmed. Accordingly, there is an effect that can prevent the wrong input occurs when entering characters such as password. And it also provides the effect of preventing the leakage of the input number by hacking.

With reference to the drawings to be described in more detail through an embodiment of the present invention.

A method of inputting text using a remote controller is illustrated in FIGS. 1 and 2. Figure 1 shows the configuration of the alphanumeric buttons assigned to the numeric buttons and numeric buttons of a remote control of a general IPTV. In FIG. 1, up to four alphabetic characters (special characters) are assigned to one numeric button. The remote control is only one embodiment, and the alphabetic characters, Korean characters, or special symbols assigned to each numeric button are not limited to the scope of the present invention, and may be allocated differently.

In order to input an English letter using the number button, press the number button with the English letter you want to input as much as the number of digits of the corresponding English letter is entered. In addition, if you add as many times the number of alphabetic characters that can be entered with the corresponding button, the alphabetic characters you want to enter automatically enters the first cycle.

2 illustrates a general method of inputting an English letter using a numeric button, and also illustrates a grid in which color is changed by pressing a numeric button used in the present invention. 2 illustrates a case in which up to four English characters can be input by one number button. The input method is the same even if only two or three English letters can be input by one number button. However, the standard of circulation differs only by a multiple of two or a multiple of three.

The alphabet entered by the remote controller is determined by the following rules.

Rule 1

English letter input = [the number of English letters that can be expressed by pressing the same number button / number of letters that can be represented by the same number button]]

In FIG. 2, the assigned four alphabetic characters are listed in order, and the alphabetical letters of the next order are input in order as the same numeric buttons are pressed according to the <Rule 1>. If the same number button is pressed more than four times, the alphabetic letters are cycled back to the initial order so that they can be entered in order from the first alphabetic character.

If only two or three English letters are assigned to the number button, the circulation criterion is a multiple of two or a multiple of three, and the alphabetic characters may be cyclically input similarly to FIG.

As illustrated in FIG. 5, the display apparatus 10 refers to a portable terminal having an apparatus to display an electric signal such as a TV as an image. When the display apparatus 10 is a portable terminal having a display window, the remote controller 20 is replaced with a plurality of buttons provided on the portable terminal. That is, when the present invention is applied to the remote control, the remote control 20 and the display device 10 are implemented as separate devices, but when the present invention is applied to the portable terminal, a plurality of buttons are provided on one single portable terminal. And the display apparatus 10 are implemented in that they are provided together. Hereinafter, although the display apparatus 10 and the remote controller 20 are described, it should be understood that the present invention is applied to the portable terminal.

In the method of inputting a password using the character input method using the remote control as described above, if any first button 21a of the remote controller 20 is pressed, at least the first button is input on the screen 10 of the display device. A pop-up window 11 is created in which the number of possible gratings 12 are arranged in sequence, and the first grating 12a disposed at one end of any of the gratings is distinguished from the other gratings. When the first button 21a is repeatedly pressed, the grids are configured to change colors or shapes so that the grids are sequentially distinguished from other grids from one side of the first grid according to the number of times of pressing.

As shown in Fig. 5, a login window 13 for certificate login is created on the screen, and a certificate password is input. Here, in the case of Hangul, the Hangul guide window 14 may be generated on the screen. In FIG. 5, when any first button 21a of the remote controller 20 is pressed to input a password (certificate password), at least the number of characters that can be input by the first button on the screen 10 of the display device is displayed. A popup window 11 is arranged in which (12) are arranged in sequence.

The first button 21a refers to any number button to which a plurality of English letters are assigned. When the first button is pressed, a popup window as shown in FIG. 3 is generated. The popup window refers to generating a lower menu on the screen when a specific input signal is inputted in the current window which is the upper menu.

In the pop-up window 11, as many grids 12 as the number of characters inputtable by the first button are arranged in sequence. In the present embodiment, since the case where four letters are assigned to the first button is described, four grids 12 are generated in FIG. This grid 12 is displayed in a popup window and is shown poeticly on the screen of the TV as shown in FIG.

In addition to the grid 12 as shown in FIG. 3, the pop-up window 11 also displays a zone for notifying the current text input mode and a zone for guiding confirmation and cancellation of an input.

When the first button is pressed, the first grating 12a disposed at one side end of the gratings is changed to another color or shape so as to be distinguished from the other gratings. In this embodiment, as shown in FIG. 2, the color of the grid is sequentially changed. In FIG. 2, when the first button is pressed once, the color of the grid located at the left end is changed to be different from the rest of the grids.

When the first button 21a is repeatedly pressed, the color changes so that the grids are sequentially distinguished from other grids from the first grid to the right as shown in FIG.

Displayed on the screen by the above configuration is simply a change in the color of the grid, the person other than the inputter can not know what character is selected, the effect that the characters used in the password is not exposed. In addition, the inputter knows the number buttons he is pressing, so that he can know how many characters are currently selected from each number button, so that the user can check the characters used in the password.

On the other hand, by changing the configuration of the above, even if the shape of the grid changes the input character has an effect that can check the input character without being exposed to the other person.

The method as described above may be further described to include a text input process. This method includes a popup window generating step S1, a character selecting step S2, and a character input step S3-1, as shown in FIG.

In the pop-up window generating step S1, when the first button 21a, which is an arbitrary number button of the remote controller 20, is pressed, at least the number of characters that can be input by the first button 21a on the screen 10 of the display device. A pop-up window 11 is created in which as many grids 12 are arranged in sequence, and the first grid 12a disposed at one end of any of the grids is distinguished from other grids. The stage that turns into. Since this step S1 is not different from the above, a detailed description thereof will be omitted.

In the character selection step S2, when the first button 21a is repeatedly pressed, the grid is changed into a color or a shape such that the grids are sequentially distinguished from other grids from one side of the first grid 12a by the number of pressing times. When the number of times the first button 21a is pressed exceeds the number of the gratings, the color or shape is changed from the first grating. Since this step S2 is also not different from the above, a detailed description thereof will be omitted.

The character input step (S3-1) refers to a step in which a character corresponding to the number of times the first button is pressed is input when the confirmation button 22 disposed on the remote controller is pressed, and the popup window 11 disappears. This step (S3-1) corresponds to the step of inputting the selected character as a password after the selection of the character is completed. Therefore, the popup window disappears and disappears from the screen of the TV since the selection of the character is completed and the confirmation of the selected character is no longer necessary. The confirmation button may vary depending on the remote controller, but in the present embodiment, the confirmation button 22 refers to the confirmation button 22 guided to the popup window of FIG. 3.

Meanwhile, the following method may be used as a method of selecting the next character to input one or more characters. In this method, the character selection step S2 is followed, and the character selection step S2 is cyclically performed.

In the present method, as shown in FIG. 6, when the first button 21a and the second button 21b different from each other are pressed, a character corresponding to the number of times the first button is pressed is input, and any one end of the pop-up window is input. The first grid 12a disposed in the is changed into a different color or shape so as to be distinguished from the rest of the grids, and the second button 21b is recognized as the first button 21a and the character selection step S2 is again performed. It is configured to further include a button change step (S3-2) to perform.

The second button 21b refers to a numeric button different from the first button 21a. Since the selection of one character is completed by pressing the first button, input of the selection character and selection of the next character are necessary. Therefore, in the present method, the character selected by the selection of the next character is inputted, and the character guided by the popup window is the next character.

When the second button is pressed, selection of a new character is started again, so the character selection step S2 must be repeated and executed again. Therefore, the grid formed on the pop-up window should be changed in color or shape again from the first grid 12a, and the second button should be recognized as a first button which is a button for character selection in the character selection step. This is not a problem because the ordinal numbers of the first button and the second button are given for convenience of distinction.

According to the method as described above, the present invention allows input of a preselected character by pressing a numeric button to which another character is assigned, and automatically selects the next character, which character is selected by a person other than the inputter. The effect is that the characters used in the password are not exposed and the user can know the number button that he or she is holding, so that the user can know how many letters are currently selected from each number button. The effect is to identify the characters used in the.

On the other hand, the selected character is wrong and can be canceled as follows. The method is configured to further include an input stop step (S3-3) in which the character input is stopped and the popup window is extinguished when the cancel button 23 disposed on the remote control is pressed in the step of the method as shown in FIG. The cancel button 23 may vary depending on the remote controller, but in the present exemplary embodiment, the cancel button 23 refers to the cancel button 23 guided in the popup window of FIG. 3.

The present invention configured as described above may be used when both the input character is Korean or English, but is preferably configured to have an input character is an English character. This is because the input of the vowel and the consonant is different from Korean and English, so the present invention is more advantageous for the confirmation of input characters in the input of English characters.

In addition, the present invention can be generated so that the remote control selection window including a grid for selecting the Hangul, numerals, and English characters on the display device screen. In this case, when the alphabetic character is selected, the alphabetic character is guided to the area for guiding the type of the current input character to the pop-up window 11 as shown in FIG. 3.

In addition, the present invention may be configured such that the pop-up window generating step (S1) is performed only when an English character is selected in the remote control selection window. This is applicable only to the case where the present invention is more limited in English letter input because the present invention is more advantageous.

In addition, the present invention may be configured to further include a grid that can select the uppercase and lowercase letters in the pop-up window. In addition, because the uppercase and lowercase letters need to be distinguished due to the characteristics of the English letter, a separate window is formed for distinguishing for convenience of input.

The overall flowchart of the password input method as described above is shown in FIG. The present invention embodies the flowchart shown in FIG.

On the other hand, the present invention does not allow a person other than the inputter without generating a plurality of grids, so that the user can not know what is being selected and the inputter can check the number button he is pressing as follows.

That is, when any first button 21a of the remote controller is pressed, a popup window including the display grid 13 is generated on the screen 10 of the display device, and the display grid 13 is connected to the first button. It is configured to display the number of times 21a is pressed by a sentence or a change in color or form.

According to this configuration, the number of times the number button is pressed is guided to the display grid 13, which is a single grid. In other words, it can be displayed as '1 time has been pressed' or by assigning a color corresponding to the number of pressing times and pressing it once, it can be displayed in the form of red.

In this configuration, even if a plurality of grids are not formed, the current input character can be prevented from being exposed by a single grid while the inputter can check the current selection character.

While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is not to be construed as limited to such embodiments and / or drawings, but is determined by the matters set forth in the claims below. . In addition, it should be clearly understood that improvements, changes, modifications, and the like apparent to those skilled in the art described in the claims are included in the scope of the present invention.
