Description

[0001] The present invention relates to a command and a character input method for a smart television remote control,

A related field of the present invention is a field of development of a simple input method of Hangul characters as a technical field related to an input device of a portable small digital device.

The change of Internet information communication through PC that began at the end of the 20th century has led to the change of information communication through mobile devices in the 21st century, and this change is being transformed into the ubiquitous world with the advent of smart TV. have. These changes are accompanied by changes in technology, and the following divisions show that the technologies that led each age are inseparable from those times.

The mail age, which was accomplished by the transfer of records by writing instruments

        Era of Voice Calls by Telephone (Whole Body)

E-mail era over the Internet with the emergence of PCs and worldwide web

With the advent of mobile devices, the era of social network society

It is already entering the ubiquitous era of connecting mobile devices and TVs in the living room of the house. In particular, when it comes to input devices, no one will deny that a typewriter in the mail era, a telephone (handset) in the voice call era, a keyboard, a mouse in the email era, and a touch screen of a mobile device in the SNS era are indispensable. Without these input devices, changes in communication would never have been possible, and the entry into the current ubiquitous era is in fact essential to the development of input devices. Recent voice recognition technology and input through gestures have emerged to overcome the limitations of existing input devices. However, these new technologies are still lacking and are not being used as the main input devices of smart TVs that will become the hub of the ubiquitous era.

Therefore, the background technology of the present invention is to provide an input method to be applied to the remote control as the main input device of the smart TV to lead the ubiquitous era.

TVs are now called smart TVs because they are so versatile that they replace the computers in the living room. However, unlike conventional computers, smart TV is not a device, but a device for leisure in nature, so the input device to be applied to it has a specificity that cannot use the keyboard and mouse used in the computer. In other words, speed of input is important, but comfort also plays an important factor in using it. For example, a TV that can be watched while lying on a sofa is essentially inconsistent when it is sitting at a desk like a computer and posing and watching like a keyboard and mouse. In this context, text input through voice recognition or gestures is the focus of attention because it is as fast and comfortable as a keyboard. Nevertheless, the limitation of these methods is that voice recognition is not as accurate as keyboard or mouse, and it is difficult to distinguish input from various people.In the case of gesture recognition, the origin of the TV remote control seeks comfort. It is not easy to perform simple commands such as channel increase and volume increase by taking an action by raising a hand. In this context, the present invention provides an easier method of controlling TV commands than voice or gesture, but provides a method that can be applied to an environment such as a window of a PC rather than a step-down menu selection using a shift key of a traditional TV menu environment. I would like to. Through this, we want to provide an input device suitable for the function of smart TV as a hub of the ubiquitous era.

The remote controller shown in FIG. 1 shows a remote controller of a conventional TV. These remote controllers are characterized by four-way keys 101 and number key blocks 102. The reason why the remote control has such a common element is that the TV has a basic purpose of receiving a broadcast channel. However, in the recent smart TV environment, TV has become a multimedia supply medium as well as watching channel broadcasting, and furthermore, it has the same function as a PC. The number key block and the four-way key, which the remote control basically has for the selection of a broadcast channel, cannot function. For this reason, the smart TV remote control shown in FIG. 2 disappears from the four-way key and the number key block, and instead shows a qwerty keyboard (FIG. 2 (I)) or a virtual keyboard capable of various inputs. Touch screen method (Fig. 2 (II)) has been adopted. Even simpler forms of remote control (Fig. 2 (III)) have emerged. In the background of the remote control shown in Figure 2 is a conventional TV remote control to enter a large number of keys when performing character input with a limited key (mainly used to assign a letter to the 12 keys of the number key block) This is because the input speed is significantly lower than that of the keyboard, which has a limitation as a text input device. Moreover, since the TV remote control cannot see the TV screen and the remote control at the same time when inputting text, the input speed is further remarkably lowered because of the inconvenience of having to alternate between the remote control and the TV screen to check for an error in the text input. On the other hand, when the key input is performed with 10 fingers of both hands, the number of keys that one finger takes is substantially 4 to 5, so that the input speed is expected to increase more than the remote control type shown in Fig. Nevertheless, unlike the PC keyboard, the keyboard shown in Fig. 2 (I) is small and needs to be operated with two fingers, so that it is not possible to overcome the inconvenience of having to alternate between the screen and the keyboard to confirm that the input is correct. It has a disadvantage. On the contrary, the touch screen method shown in FIG. 2 (II) has the advantage that the TV screen and the touch screen of the remote controller are synchronized so that the user does not have to watch the TV screen while inputting. However, the price of the remote controller, which is no less than the price of the TV, will be limited in terms of economics.

As described above, the most important element of the input method to be applied to the remote control of the smart TV is that the field of view should be able to focus on the TV during the input. In other words, it should be an input method that can realize Eyes-Free remote control free from the remote control. This is the reason that the menu selection method using the four-way key in the existing remote control became the main control method. In other words, the four-way key has the advantage that the finger operating the four-way key can recognize the position of each four-way key does not have to look at the remote control at the time of operation.

Another object of the present invention is to provide a method in which a finger can recognize a key position of a remote controller while the view is fixed to a TV screen and thus can operate the apparatus without looking at the remote controller.

The remote control input method using the 9-key of the present invention provides an input method that is suitable for performing the hub function of the ubiquitous era for the simplicity, quickness, and securing the accuracy of the field of view. In addition, it can be applied to the form of a general TV remote control shown in Figure 1 can be provided at a low cost and at the same time provides the advantage that the user can easily adapt.

        The remote control of the TV was the main function of simply changing the channel and adjusting the volume before the multi-media broadcasting called smart TV or internet TV. But as these multimedia broadcasts began, TVs became devices that needed the same level of input and output as computers. As a result, the input device has reached its limit in the form of a conventional button array remote control. In other words, the function of the remote control is complicated to arrange all the buttons for each function on the remote control. The advantage of the existing button-based remote control is that buttons with similar functions are arranged next to each other so that users do not have to look at the buttons during operation. For example, when you press a button to increase the volume, you must first look at the remote control to determine its position, but once you operate the key, subsequent operations no longer need to see the key. The reason is that after pressing the volume up button, the only action required is to stop the volume control or operate the button to decrease the volume again. You can press a volume down button because the location is easily identified with your finger, so you never have to look at the remote.

        In this context, the present invention intends to provide a method of making most inputs with only nine keys to minimize the movement of the finger so that the position of the keys can be easily identified, and the present invention will be described in detail with reference to the following embodiments.

The keyboard shown in FIG. 3 is a 9-key keyboard for inputting Korean and English as the core of the configuration of the present invention described in the following embodiments, and in particular, utilizes a multifunction key indicated in red.

<How to input consonants in 9-key consonant keyboard including vowel input activation key>

        3 (I) and FIG. 4 show a 9-key keyboard for inputting Korean characters. These keyboards feature one key for vowel entry, a central red key (named Hanalky). A vowel input method using one key is already known from Korea Patent 10-2012-7004777. By using the 'Hanalki' shown in Figure 4, you can easily enter the Hangul alphabet with only nine keys.

The consonant keyboard of FIG. 4 is a rearrangement of only the consonant array of the existing Hangul input method into seven or eight keys, and the input method is the same as the consonant input method of the existing Hangul input method. 4 (I) shows a consonant arrangement of Samsung Cheonjiin, FIG. 4 (II) shows a consonant arrangement of Cheonjiin's input method (Patent 10-0201211) by Mr. Cho Kwan-hyun, and FIG. 4 (III) shows a consonant arrangement of KT Naraggle. In addition, the consonant array can be arranged arbitrarily on keys other than 'Hanalki'. Using Hanalki, Hangul consonants can be arranged freely within a 9-key keyboard.

        In addition, when using 'Hanal key', the consonant input method of Cheonjiin method (Fig. 4 (I), Fig. 4 (II)) requiring a consonant collision prevention function is placed in the 9-key keyboard with a blank key 'Off' key. The input of consonants is easy to bring.

For example, in the case of the consonant keyboards of FIGS. 4 (I) and 4 (II), when 'each' is inputted, 'AB', which is the base of the first letter 'AB', and 'AB', which is the first letter of the second letter, are Since it is assigned to the same key, after entering the base letter 'ㄱ' of the first letter, press the 'Off' key, and then press the 'a' key again. If you press the 'Off' key twice in a row, the 'space' is entered so that the Hangul alphabet is entered using only 9 keys. Unlike the consonant keyboards of FIGS. 4 (I) and 4 (II), the consonant input of the 'naratgle' type shown in FIG. 4 (III) does not have a consonant collision element and thus does not need the function of the 'off' key. A separate key for input is more inconvenient than a consonant keyboard consisting of seven consonant keys shown in FIGS. 4 (I) and 4 (II). Therefore, it is preferable that the consonants are arranged on seven keys so that the input of the Hangul alphabet including a space input except nine symbols is made up of nine keys.

<How to input vowel>

        Vowel input is made after pressing the 'Hanal key' of the consonant keyboard shown in FIG. 4 to activate the vowel keyboard shown in FIG. FIG. 5 (I) is a combination of all the Korean vowels with the combination of Samjae, Cheonjiin, which is a well-known principle of Hangul creation. In FIG. 5 (II), the short vowels are input by pressing each vowel key once except for 'ㅐ' and 'ㅔ', and in the case of the double vowels, each key is pressed twice. In the case of double vowels, the short vowels constituting the double vowels are inputted by pressing the designated keys in order. For example, in the case of 'ㅑ', the user presses the 'ㅏㅑ' key twice and enters 'ㅐ' by pressing the 'ㅏㅑ' key followed by the 'ㅣ' key. In the case of 'ㅘ', press the 'ㅗㅛ' key followed by the 'ㅏㅑ' key. In the case of FIG. 5 (III), 'ㅐ' and 'ㅔ' are assigned to separate keys, so a single vowel is input by pressing each key once, and a double vowel is input by pressing each key twice. Enter the short vowels that make up the order.

The advantages and disadvantages of the vowel keyboard shown in FIG. 5 are the most intuitive and easy to understand in the case of FIG. 5 (I), but the number of presses is increased. In the case of FIG. Fig. 5 (III) has the greatest advantage. In the case of the vowel keyboard, the method of switching to the consonant keyboard by pressing 'Hanal Key' again when the vowel input is completed is a method applicable to all the vowel keyboards of FIG. 5 and in the case of FIG. As disclosed in -7004777, input efficiency can be improved by automatically converting to a consonant keyboard when the vowel is completed.

In relation to the search process, the vowel keyboards of Figs. (I) and (II) have advantages over the vowel keyboards of Figs. The other thing is that it has a moving key keyboard activation key (501). In other words, these vowel keyboards provide a method that can be converted to a moving key keyboard even if it is not converted to a consonant keyboard, thereby providing a method for selecting and entering a search word easily without leaving a finger having a 9-key keyboard.

<Expand Key Function>

Text input to the remote control for the smart TV is mainly a command input for searching or controlling the TV, so when inputting for these functions, it has a different aspect from the sentence input that sends and receives a message like a smart phone. The biggest difference this feature brings is the space input. In the smart TV or general TV, the search is mainly performed on channels, broadcast contents, and VOD titles, and thus, text input required for searching is possible without a blank input. For example, when searching for a VOD title called "Batman Returns," you can omit the space after "Batman" and type "Batman Returns" to make the search results intact. Therefore, when the 'off' key shown in the consonant keyboard of FIG. 4 is pressed twice, it is preferable to activate the 'move key' keyboard instead of the 'blank' input. That is, if the 'key' key can be activated by pressing the 'Off' key twice, the character input for searching and the selection / execution of the search item displayed on the screen after the character input can be completed as 9 keys. . This way, the search can be completed without the finger having to leave the 9 key. This is because the finger grasps the position of the 9 key, so that not only the character input but also the finger movement for switching to the moving key keyboard can be made without looking at the keyboard with the eyes, thereby bringing the advantage that the view is fixed to the TV screen.

        As shown in FIG. 6, when the virtual keyboard is shown on the TV screen and the 'a' key is pressed on the remote controller, the pressed state of the 'a' key (displayed in yellow) is simultaneously displayed on the virtual keyboard, so that the finger is tactile on the remote controller. It is desirable to be able to visually check the key position visually on the TV screen at the same time.

<Hangul Input: Initial Search and Name Search>

In the case of Korean search, the vowel input is omitted when searching using only the consonant, thus reducing the number of key inputs. Moreover, no vowel entry is required, so there is no need for a vowel activation key. Therefore, in case of granting the function of 'moving key keyboard' instead of 'activating vowel input' of 'Hanalkey', instead of pressing 'Off' key twice as in Example 3, 'Hanalkey' is pressed once Therefore, user convenience can be further increased.

In addition, the contents of the word prediction input method shown in the seventh to tenth embodiments may be applied to the search word selection and input process in the search through the initial input.

<Go to keyboard>

The moving key board shown in FIG. 3 (IV) provides a function of matching the 9-key keyboard with the moving key and the letter input key separately in the conventional general TV remote controller. The keyboard can also provide volume and channel change functions, providing a way to unify the control of the TV with nine keys. Since the volume key and the channel change key are not duplicated at the time of character input or search using the move key, the volume key and the channel change key may be activated by pressing the space key or the hanal key as in Embodiments 3 and 4, or a separate 'move key keyboard mode change' key. It is also possible to set 301 so that volume and channel can be changed at any time.

Nevertheless, in the consonant keyboard structure of FIG. 3 (I), when activating the 'moving key keyboard' by pressing the 'off' key twice, the volume and channel can be adjusted without the finger leaving the 9 key. Of course, the action of pressing 'Off Key' twice is only applicable if 'Active Key Keyboard' is activated instead of 'Blank' input function.

<English: Enter a sentence>

The English keyboard shown in FIG. 3 (II) inputs English characters using multi-tapping. Unlike Hangeul, there is no distinction between consonants and vowel keyboards, so the red 'Hanalki' in the center is only responsible for the space function. In other words, pressing the space key once starts the input of a new character in the same way as the Korean consonant collision prevention function. For example, if you press the 'abc' key twice, then the 'Off' key, then the 'abc' key, 'b' is entered and then 'a' is entered. If you press the 'abc' key twice and then press the 'Off' key twice in succession, enter 'b' followed by a space. This is the same as the input method of the Korean consonant keyboard shown in FIGS. 4 (I) and 4 (II).

Like English in Korean, English input requires multi-tapping reset function when pressing the red 'Hanalkey' of Fig. 3 (II) once in VOD title search and channel search on TV that can perform search function even if there is no space input. If you press and double-click to activate the moving keyboard function, the selection and execution of the search item displayed on the screen after the text input and the text input for the search can be completed as 9 keys.

In the case of searching through the English word input of the present embodiment, the keyword selection and input process contents of Embodiments 7 to 10 may be applied.

<English Input: Application of Word Prediction Input Method>

In English, unlike Korean, character input is commonly performed using a predictive text input method. In this case, the red 'Hanalkey' of FIG. 3 (II) does not require a multi-tap reset function. All you need to do is activate the keyboard.

For example, the word prediction input method is to press the 'abc', 'mno' and 'wxyz' keys one by one to input 'boy'. After it is pressed once, ['a', 'b', 'c'], ['m', 'n', 'o'], ['w', 'x', 'y', 'z' These predicted words are displayed in the predicted word list window 712 so that one of the predicted words that are selected by combining one letter from three groups of] can be selected. (Fig. 7) In order to select / enter the predicted words to be input from the predicted words displayed as described above, pressing the 'Hanal key' (the red key marked with '+') activates the moving key keyboard 811. As shown in FIG. 8, the English keyboard 711 is switched to the moving key keyboard 811. After the keyboard has been converted to a moving key keyboard, pressing the Down (↓) key 801 once will move the selection from 'any' that was initially selected in the list of predicted words to 'boy' one column below. In this state, when the 'confirm' key 802 is pressed, the selected prediction word 'boy' is inputted.

<Predictive word input using numeric input>

In the seventh embodiment, the down arrow key 801 is pressed in the moving key keyboard shown in FIG. 8 to select the predicted word, and the enter key is pressed. If you replace this process with numeric input, the selection process becomes easier. For example, when a long key is pressed, a number is input instead of a function of the original key of the moving key, and as a result, a predicted word corresponding to the number of the word list window 812 of FIG. 8 is input. In other words, to enter 'boy', press and hold the '2' key (corresponding to the upward movement key). In this case, the key press for typing 'boy' is completed in one step. In the case of the remaining predictive words, the input is made by one key press, which greatly reduces the number of key presses.

<Extension of Keyboard Configuration>

        The structure of the moving key board generally has left, right, up and down four-way moving keys of the type shown in FIG. 3 (IV). In Examples 5 to 7, a desired list was selected by using the general moving keyboard. However, as described in Embodiment 8, when each predicted word and the key correspond to one-to-one without using a moving key and the predicted word is input by one key press, the number of key presses is greatly reduced, thereby increasing user convenience. Done. For this purpose, the configuration of the general moving key board is modified as the moving key board of FIG. The moving key board of FIG. 9 does not have the left and right moving keys. Even Shanghai donkey is used for the selection of predicted word list group, not the navigation key function for selecting the predicted word from the predicted word list. Here, 'predicted word list group' means a predicted word when the number of all predicted words predicted by character input is larger than the number of predicted words that can be selected / inputted by the moving keyboard (the moving keyboard shown in FIG. 9 is '6'). Refers to each group subdivided by the number that can be input with the whole keyboard key.

        For example, the moving key board of FIG. 9 has six keys on the left and right ('1', 'except the' definition 'key and the Shanghai donkey (actually, the functions of the' previous list 'key and' next list 'key). 3 ',' 4 ',' 6 ',' 7 'and' 9 'key) can be entered into the prediction word. In other words, when these number keys are pressed, the predicted word corresponding to the number is input. Accordingly, the number of predicted words that can be input to the 'keyboard' of FIG. 9 is determined by the number keys ('1', '3', '4', '6', '7', and '9' keys). Corresponds to the number.

In the prediction word present list windows 903 and 904 shown in FIG. 9, six prediction words are arranged to the left and right. In fact, the words predicted when the 'abc', 'mno', and 'wxyz' keys are pressed in sequence are shown. More than six words show six predicted words that can be entered in the moving key board in the 'current list window' (903, 904) and the rest in the 'next list window' (905, 906). In this case, the user can easily select a prediction word to input. If the predicted word to be entered is arranged in the 'next list window', the 'next list' key is arranged to be arranged in the 'current list window' and then the input key is input by pressing the designated key. For example, if the predicted word to be input in FIG. 9 is 'coz', the word is placed in the 'next list window'. To place it in the 'current list window', first press the 'next list' key. Then, as shown in FIG. 10, 'coz' is placed in the 'current list window' (1003, 1004), and in this state, 'coz' is input by pressing the 4 key corresponding to 'coz'.

<Use background color of keyboard>

As shown in the ninth embodiment, when the number key is used instead of the moving key of the moving key board, the number of key presses for selecting / inputting a predicted word is greatly reduced than when using the Shanghai donkey. In order to further increase user convenience due to the decrease in the number of key presses, a method of utilizing the background color of the numeric keys of the moving keypad as shown in FIGS. 11 and 12 will be presented in this embodiment.

In Example 9, numbers are also displayed in the predicted word list in order to associate the numeric keys with the predicted words in the predicted word list window. In order to further enhance the linkage between the virtual keyboard 901 and the predicted word list 902 displayed on the screen by actually displaying the numbers, if the same background color is applied to the numeric keys and the predicted word list of the virtual keyboard instead of these numbers, It is possible to easily associate the predicted words with the numeric keys of the virtual keyboard without checking the user, so that the user can easily input the keys of the remote controller.

Accordingly, the contents shown in FIGS. 11 and 12 are the same as those shown in FIGS. 9 and 10, and the user applies a key input for inputting the prediction word by applying a different background color instead of the numbers to the virtual keyboard and the prediction word list. It is easy.

The mobile keyboard configuration for the predicted word input method shown in Embodiments 7 to 10 can be applied to the case of Hangul, and in particular, the selection / input process of the search word can be equally applied in the search process through the initial input.

Not applicable
