After the at least one recommendation text item is displayed, when the first recommendation text item is selected from the at least one recommendation text item through the input unit 280, the controller 290 is included in the first text item around the first text item. The display 230 may be controlled to display the new at least one recommended text item for the combination of the text and the text included in the first recommended text item.

For example, after four recommended text items 410-1, 410-2, 410-3, 410-4 are displayed around the first selected text item "D", as shown in FIG. 5, through the input unit 280. When the second recommendation letter item "O" is selected for the second time, the controller 290 searches for at least one recommendation letter item for the "DO" selected by the user, and then, as shown in FIG. Display unit 230 to display a character item including items "T", "L", "N", and "M" (610-1,610-2,610-3,610-4) around the first selected character item "D". ) Can be controlled.

In addition, when the second recommended letter item is selected, the first selected letter item may continue to be displayed as "D". However, this is only an example. The first selected letter item is changed to "O". Can be displayed. In this case, the letter item in which "O" is originally placed may be changed to "D" and displayed.

As described above, when one of the recommended text items is selected, the position of the pointer for inputting the text may be minimized by the user by not changing the position where the new recommended text item is displayed.

In addition, the controller 290 may include at least one recommendation letter item for the "DO" selected by the user with the highest priority at the position of "O" 620-2, which is the most recently selected recommendation letter item. You can display the item so that you can place it. If one of the recommended text items is selected, the user inputs the text by placing the recommended text item having the highest priority among the new recommended text items at the position where the highlight is placed, without changing the position where the new recommended text item is displayed. It is possible to minimize the movement of the pointer.

As illustrated in FIG. 5, the controller 290 may input the text “DO” selected by the user into the text input window 330.

After the at least one recommended text item is displayed, and if a second text item other than the first text item and the at least one recommended text item is selected through the input unit 280, the controller 290 may display the second text item around the second text item. The display unit 230 may be controlled to display at least one recommended text item for a combination of a text included in the first text item and a text included in the second text item.

For example, after selecting the text item up to the second time, after four recommended text items 610-1, 610-2, 610-3, 610-4 are displayed around the text item "D", as shown in FIG. If a third character item "G" other than the recommended character items 610-1, 610-2, 610-3, 610-4 is selected through 280, the control unit 290 at least one of the "DOGs" selected by the user. After searching for the recommended text item of, as shown in FIG. 8, the searched new recommended text items "M", "E", "A", and "L" (810-1, 810-2, 810-3, 810-4) are counted. The display 230 may be controlled to display around the first selected text item "G".

As another embodiment of the present invention, when the first text item is selected through the input unit 280, the controller 290 may control the display 230 to display a refresh item in the text input UI.

In this case, the refresh item is a function item for searching for and displaying a recommendation letter item having a next rank when there is no character item that the user wants to select in the displayed recommendation item.

For example, when the letter item “D” is selected through the input unit 280, the controller 290 may display three recommended letter items “A”, “I”, and “O” 910 as illustrated in FIG. 9. -1,910-2,910-3 and the refresh item "Re" 910-4.

When the refresh item 910-4 is selected through the input unit 280, the controller 290 recommends at least one recommendation letter item for the letter item “G” as shown in FIG. 10 in the next order. The character items "U", "K", and "Y" (1010-1, 1010-2, 1010-3) may be changed and displayed.

In this case, as shown in FIGS. 9 and 10, the refresh item may be displayed in an area where the recommended text item is displayed, but this is only an example and may be located in another area in the text input UI 320. have. For example, as shown in FIG. 11, the refresh item 1120 may be disposed adjacent to the recommended letter item 1110-3.

Meanwhile, according to an embodiment of the present disclosure, the controller 290 may display a function item for providing various functions in addition to the recommended text item. In this case, the function item may include a space item performing a space bar function, an enter item performing an enter key function, a delete item performing a function of deleting a previously input character, and a special item. Include at least one of special character items for text entry

Specifically, a combination of characters input through the input unit 280 completes a new word by inputting one of the words stored in the dictionary database 251 and the user database 253 stored in the storage unit 250 or another character. If possible, the control unit 290 may control the display unit 250 to additionally display at least one function item in addition to the at least one recommended text item.

For example, when a combination of characters input through the input unit 280 may complete one word or another word through input of another character, such as "DOG" and "SELECT", the controller ( 290 may control the display unit 250 to display two recommended text items 1210-1 and 1210-2 and two function items 1220-1 and 1220-2 as shown in FIG. 12. Can be.

Alternatively, when the combination of characters input through the input unit 280 is one of words stored in the dictionary database 251 and the user database 253, and a new word cannot be completed through input of other characters, the controller 290 ) May control the display unit 250 to remove at least one recommended text item and to display at least one function item.

For example, when a combination of characters input through the input unit 280 cannot complete a new word through input of other characters, such as "SELECTION", "BEAUTIFULLY", or the like, the controller 290 is illustrated in FIG. As described above, the display unit 250 may be controlled to display four function items 1310-1, 1310-2, 1310-3, and 1310-4.

Alternatively, when the combination of characters input through the input unit is not a word stored in the dictionary database 251 and the user database 253, the controller 290 removes at least one recommendation letter item and selects at least one function item. The display unit 250 may be controlled to display at least one recommended letter item in the displayed area.

For example, if the combination of characters input through the input unit 280 is not a word stored in the dictionary database 251 and the user database 253, such as "SWEETYKS", the control unit 290 is shown in FIG. As described above, the display unit 250 may be controlled to display four function items 1310-1, 1310-2, 1310-3, and 1310-4.

In particular, when an input command for a word not stored in the dictionary database 251 is received using the displayed at least one function item, the controller 290 may record the received word in the user database 253. Can be.

For example, when the combination of the input characters is "SWEETYKS", when the enter key item 1310-1 or the space item 1310-2 is selected from the displayed function items, the controller 290 selects "SWEETYKS". Can be recorded in the user database 253.

As described above, by registering a word not stored in the dictionary database 251, such as an ID, in the user database 253, the user can later easily identify a word not stored in the dictionary database 251, such as an ID. Can be entered.

However, when a password is input using the text input UI, the controller 290 may not display at least one recommended text item. In detail, since the password must be kept confidential, the controller 290 may not provide a recommendation item when the password is input, and may not store the combination of characters input as the password in the user database 253. .

Meanwhile, in the embodiments described with reference to FIGS. 3 to 13, the recommended text item and the function item are partially overlapped with the text item arranged adjacent to the selected text item. However, this is only an example. The recommended text item and the function item can be displayed.

For example, when selecting a text item using a four-way key, such as a remote control, as shown in FIG. It can be displayed in some areas.

Through the display apparatus 200 as described above, the user can more easily perform text input using the text input UI.
