In the prior art, when an input on a display device is used for inputting, for example, when a user needs to input a movie name, a character input interface (i.e., an interface with a soft keyboard) is called up through a remote controller, and characters displayed on a display screen of the display device are selected through physical keys (such as an upper key, a lower key, a left key, a right key, and a confirmation key) of the remote controller, so as to input the movie name. Specifically, for a character input interface displayed on a display screen, for each character on a soft keyboard, a key value of each character in the soft keyboard is marked by an index in an input method, and each character is associated with a plurality of characters, so that each character needs to store the key value of the character associated with the character. When the film name is input, according to the index of the key value of the current focus, determining the character corresponding to the current key value, and then calculating the relation between each character having the relation with the character of the current focus and the coordinate of the character of the current focus according to the moving direction of the physical key, thereby determining the key value of the focus after the physical key moves.
Therefore, in the prior art, the key value of the current character is associated with the key values of other characters near the character, and the movement of the focus, that is, the switching of the characters is controlled by the movement direction of the focus input by the user through the physical key. Each character in the software disk needs to establish an association relation with other characters near the character, and the number of characters in the software keyboard is large, so that the storage space of the display device is occupied. Moreover, when the focus moves, the relation between each character in the relation with the character at the current focus and the coordinates of the character at the current focus needs to be calculated according to the moving direction of the physical keys, so that the calculation amount is large, the workload of a display device processor is increased, the focus moving efficiency is low, and if the calculation is wrong, the focus moving error is caused, and the precision of the focus moving is reduced.
To solve at least one of the above problems, the present application proposes: in the display device, the key value index of each character in the soft key panel zone is related to the arrangement sequence of the row and the column where the character is located, for example, the key value index of each character is stored in a two-dimensional array, for example, the key value index of the character located at the first row and the first column position corresponds to a two-dimensional array keyboard _ layout _ number [0] [0], and the key value index of the character located at the third row and the fourth column position corresponds to a two-dimensional array keyboard _ layout _ number [2] [3], so that when the character is switched, the display device can directly find the two-dimensional array corresponding to the key value index of the switched character according to the received moving direction of the physical key and the position of the current character where the selector is located, and accordingly, the position of the selector after the movement is given. Namely, the key value index of the next character is directly found through the key value index of the current character, the focus moves fast and accurately, and the user experience is improved. In addition, the display equipment only needs to store the two-dimensional array corresponding to the key value index of each character, and the occupied memory space is small.
Fig. 2A to 2N are schematic diagrams illustrating a GUI400 provided by the display apparatus 200 by operating the control device 100.
As shown in fig. 2A, when a user needs to input related content, the control apparatus 100 can be operated to enable the display device to provide a GUI400 for the display, where the GUI400 may include: an input method keypad 401, and a selector 402 for indicating that a character in the keypad 4011 is selected.
Of course, other items may also be included in the GUI400, for example, an identification box 403 for indicating a confirmation search, a text input box 404 for displaying input text content, a cursor 4041 in the text input box 404, a signal strength identification of a wireless network, time information, a date, a return home page icon, recommended content (not shown in fig. 2A) associated with characters input by the user, and the like, and the embodiment of the present application does not limit other items in the GUI400 except for the input method softkey region 401, the text input box 404, and the identification box 403 for indicating a confirmation search. Here, if the text input box 404 includes the cursor 4041, the cursor 4041 may be periodically displayed or hidden.
It is noted that an item refers to a visual object displayed in the GUI400 provided by the display device to identify corresponding content such as an icon, a thumbnail, a link, and the like. The presentation forms of items are often diverse. For example, the items may include text content and/or images for displaying thumbnails related to the text content. As another example, the item may be text and/or an icon for an application, and as another example, the item may also be a virtual key in the input method softkey extent 401.
It should be further noted that the display format of the selector 402 may be the focus object. The movement of the display focus object in the display apparatus 200 may be controlled to select or control items according to an input of a user through the control device 100. Such as: the user may select and control items by controlling the movement of the focus object between items through the direction keys on the control device 100. The identification form of the focus object is not limited. Illustratively, the position of the focus object is realized or identified by setting the background color of the item as shown in fig. 2A, and may also be identified by changing the border line, size, transparency, and outline and/or font, etc. of the text or image of the focused item.
For example, the input method software keyboard zone 401 may be an input method software keyboard zone corresponding to an input method, where the input method software keyboard zone 401 may be different according to different language types, and for example, the input method software keyboard zone 401 may be divided into 34, 35, 36, 37, 38, 39, 40, 46, 54 keys and the like according to different language types. In the embodiment of the present application, the example that the input method software keyboard region 401 includes 34 keys is described.
As shown in FIG. 2A, the input method soft key panel area 401 includes 34 keys, including four rows, wherein the first row includes 10 keys (i.e. characters), the second row and the third row include 9 keys, respectively, and the fourth row includes 6 keys, wherein the key value index of each key is related to the arrangement order of the row and column where the key value is located, for example, the key value index of the key located in the sixth column of the second row is key _ layout _ number [1] [5], so that the two-dimensional arrays corresponding to the 10 key values included in the first row are key _ layout _ number [0] [0] -key _ layout _ number [0] [9], respectively, the two-dimensional arrays corresponding to the 9 key values included in the second row are key _ layout _ number [0] [0] -key _ layout _ number [1] [8], respectively, and the second row includes 9 key values corresponding to the second key values are key _ layout [2] [8], [ key values ] [2] respectively, the four rows include 6 key values corresponding to two-dimensional arrays of key _ layout _ number [3] [0] -key _ layout _ number [3] [5 ].
In practical applications, the user can move the position of the selector 402 in the input method software keyboard area 401 by operating physical keys of the control device, such as the "up" key, the "down" key, the "left" key, the "right" key, and the "ok" key.
If the user presses the "up" key in the pressure control device, the display device acquires that the character switching instruction input by the user is that the selector 402 moves to the previous row of the current key position, the display device acquires the current key position of the selector 402, and the key position of the selector 402 is adjusted according to the character switching instruction.
Illustratively, if the current key position of the selector 402 is any key position in the top row (i.e. the first row) in the soft key pad area 401, as shown in fig. 2B, the key value index is keyboard _ layout _ number [0] [5], after the display device receives the character switching instruction sent by the user pressing the "up" key in the pressure control device, since no key position exists above the current key position of the selector 402 in the top row (i.e. the first row) in the soft key pad area 401, when the character switching instruction instructs to move the selector 402 upwards, as shown in fig. 2B, the selector 402 is located on the selected current key position and does not move.
If the current key position of the selector 402 is any key position of the second row, the third row or the fourth row, the user presses the 'up' key in the voltage control device, the display device judges the size between the numerical value of the column corresponding to the key value index of the key position where the selector 402 is currently located and the total column number of the key position of the previous row, as shown in fig. 2C, the current key position of the selector 402 is the fifth column of the second row, the key value index is keyboard _ layout _ number [1] [4], after the display device receives the character switching instruction sent by the user pressing the 'up' key in the voltage control device, because 10 columns are arranged in the first row, the current key position of the selector 402 is the fifth column of the second row, the numerical value of the current key position column of the selector 402 is smaller than the total column number of the first row, therefore, the display device subtracts 1 from the row value of the current key position of the selector 402, the column value is unchanged, and obtains the key position after the selector 402 is moved, that the index of the keyboard _ layout [0] [4], as shown in fig. 2D, the selector 402 is controlled to move to the fifth column of the first row, i.e., the selector 402 selects the character "t".
For another example, as shown in fig. 2E, the current key position of the selector 402 is the ninth column in the third row, the key value index is keyboard _ layout _ number [2] [8], and after the display device receives the character switching instruction sent by the user pressing the "up" key in the pressure control device, since there are 9 columns in the second row and the current key position of the selector 402 is the ninth column in the third row, the numerical value of the current key position column of the selector 402 is equal to the total column number of the second row, the display device subtracts 1 from the row value of the current key position of the selector 402, and the column value is unchanged, obtains the key position after the selector 402 is moved, i.e., the key value index of the key position after the movement is keyboard _ layout _ number [1] [8], as shown in fig. 2F, and controls the selector 402 to move to the ninth column in the second row, i.e., the selector 402 selects the character "l".
If the value of the current key position column of the selector 402 is greater than the total number of columns in the previous row, the selector 402 moves to the last key position in the previous row, which can refer to the case that when the selector 402 moves to "down", the value of the current key position column of the selector 402 is greater than the total number of columns in the next row, and then the selector 402 moves to the last key position in the next row.
If the user presses the "down" key in the pressure control device, the display device acquires that the character switching instruction input by the user is that the selector 402 moves to the next line of the current key position, the display device acquires the current key position of the selector 402, and the position of the selector 402 is adjusted according to the character switching instruction.
For example, if the current key position of the selector 402 is any key position in the last row (i.e. the fourth row) in the soft key pad area 401, as shown in fig. 2G, the key value index is keyboard _ layout _ number [3] [2], after the display device receives the character switching instruction sent by the user pressing the "down" key in the pressure control device, since no key position exists below the current key position of the selector 402 in the last row (i.e. the fourth row) in the soft key pad area 401, when the character switching instruction instructs to move the selector 402 downwards, as still shown in fig. 2G, the selector 402 is located at the selected current key position and does not move.
If the current key position of the selector 402 is any key position of the first row, the second row or the third row, the user presses the 'down' key in the pressure control device, the display device judges the size between the numerical value of the column corresponding to the key value index of the key position where the selector 402 is currently located and the total column number of the key position of the next row, as shown in fig. 2H, the current key position of the selector 402 is the seventh column of the third row, the key value index is keyboard _ layout _ number [2] [6], after the display device receives the character switching instruction for moving the selector 402 downwards, because there are 6 columns in the fourth row, the current key position of the selector 402 is the seventh column of the third row, the numerical value of the current key position column of the selector 402 is greater than the total column number of the last row, therefore, the display device adds 1 to the row value of the current key position of the selector 402, changes the column value into the numerical value of the last column of the last row, and obtains the key position after the selector 402 is moved, i.e., the key-value index of the key position after shifting is keyboard _ layout _ number [3] [6], controls the selector 402 to shift to the fourth row and sixth column, i.e., the selector 402 selects the symbol indicating the search, as shown in fig. 2I.
For another example, as shown in fig. 2E, the current key position of the selector 402 is the ninth column in the third row, the key value index is keyboard _ layout _ number [2] [8], and after the display device receives the character switching instruction for moving down the selector 402, since there are 6 columns in the fourth row and the current key position of the selector 402 is the ninth column in the third row, the numerical value of the current key position column of the selector 402 is greater than the total column number in the last row, the display device adds 1 to the row value of the current key position of the selector 402, and the column value becomes the numerical value in the last column of the last row, obtains the key position after moving the selector 402, i.e., the key value index of the key position after moving is keyboard _ layout _ number [3] [6], and still as shown in fig. 2I, controls the selector 402 to move to the sixth column in the fourth row, i.e., the selector 402 selects the symbol indicating the search.
As shown in fig. 2J, the current key position of the selector 402 is the ninth column of the first row, the key value index is keyboard _ layout _ number [0] [8], and after the display device receives the character switching instruction for moving down the selector 402, since there are 9 columns in the second row and the current key position of the selector 402 is the ninth column of the first row, and the numerical value of the current key position column of the selector 402 is equal to the total column number of the second row, the display device adds 1 to the row value of the current key position of the selector 402, and the column value is unchanged, obtains the key position after the movement of the selector 402, i.e., the key value index of the key position after the movement is keyboard _ layout _ number [1] [8], and controls the selector 402 to move to the ninth column of the second row, i.e., the selector 402 selects the character "l", as shown in fig. 2F.
As shown in fig. 2C, the current key position of the selector 402 is the fifth column of the second row, the key value index is keyboard _ layout _ number [1] [4], and after the display device receives the character switching instruction for moving down the selector 402, since there are 9 columns in the third row and the current key position of the selector 402 is the fifth column of the second row, the numerical value of the current key position column of the selector 402 is smaller than the total column number of the third row, the display device adds 1 to the row value of the current key position of the selector 402, and the column value is unchanged, obtains the key position after the movement of the selector 402, i.e., the key value index of the key position after the movement is keyboard _ layout _ number [2] [4], and controls the selector 402 to move to the fifth column of the third row, i.e., the selector 402 selects the character "v", as shown in fig. 2K.
If the user presses the "left" key in the pressure control device, i.e. controls the selector 402 on the display device to move from the column where the current key position is located to the previous column, and the row value is not changed, the display device adjusts the position of the selector 402 according to the current position of the selector 402 and the key input instruction.
For example, as shown in fig. 2L, when the current key position of the selector 402 is the first column in the third row and the key value index is keyboard _ layout _ number [2] [0], i.e. located in the first column in the third row, after the display device receives the character switching instruction sent by the user pressing the "left" key in the pressure control device, since the current key position of the selector 402 is located in the first column in the third row in the softkey panel 401 and no key position exists in the left direction, when the character switching instruction instructs to move the selector 402 to the left, as still shown in fig. 2L, the selector 402 is located in the current key position for selection and does not move.
For example, as shown in fig. 2C, the current key position of the selector 402 is the fifth column of the second row, the key value index is keyboard _ layout _ number [1] [4], since there are 9 columns in the second row, the numerical value of the column where the current key position of the selector 402 is located is not the first column of the row where the current key position is located, therefore, after the display device receives the character switching instruction sent by the user pressing the "left" key in the pressure control device, the display device subtracts 1 from the column value of the current key position of the selector 402, the row value is unchanged, the key position after the movement of the selector 402, i.e., the key value index of the key position after the movement is keyboard _ layout _ number [1] [3], as shown in fig. 2M, the selector 402 is controlled to move to the fourth column of the second row, i.e., the selector 402 selects the character "f".
If the user presses the "right" key in the pressure control device, i.e. controls the selector 402 on the display device to move from the column where the current key position is located to the next column, and the row value is not changed, the display device adjusts the position of the selector 402 according to the current position of the selector 402 and the key input instruction.
For example, as shown in fig. 2E, when the current key position of the selector 402 is the ninth column in the third row, i.e. is located in the last column in the third row, and after the display device receives a character switching instruction sent by the user pressing the "right" key in the pressure control device, since the current key position of the selector 402 is the last column in the third row in the softkey pad area 401, and no key position exists on the right side thereof, when the character switching instruction instructs to move the selector 402 to the right, as still shown in fig. 2E, the selector 402 is located on the current key position for selection and does not move.
For example, as shown in fig. 2C, the current key position of the selector 402 is the fifth column of the second row, the key value index is keyboard _ layout _ number [1] [4], since there are 9 columns in the second row, the numerical value of the column where the current key position of the selector 402 is located is not the last column of the row, therefore, after the display device receives the character switching instruction sent by the user pressing the "right" key in the pressure control device, the display device adds 1 to the column value of the current key position of the selector 402, the row value is not changed, the key position after the movement of the selector 402, i.e., the key value index of the key position after the movement is keyboard _ layout _ number [1] [5], as shown in fig. 2N, the selector 402 is controlled to move to the sixth column of the second row, i.e., the selector 402 selects the character "h".
The user moves the position of the selector 402 to the key position corresponding to the character to be input in the input method softkey pad area 401 by operating the control means, and the display device displays the selected character in the text input box 404 by pressing the "ok" key in the control means.
Fig. 3 illustrates a flowchart of a method of moving a selector in an input method of a display device.
Referring to the method shown in fig. 3, the method comprises the steps of:
and S301, displaying a user interface.
The user interface comprises an input method soft keyboard area and a selector used for indicating that a character in the input method soft keyboard area is selected, wherein a key value index of each character in the input method soft keyboard area is related to the arrangement sequence of the rows and the columns where the character is located.
S302, acquiring a character switching instruction input by a user.
S303, moving the selector from the position of the current character to the position of the switched character according to the keyboard index of each character, so that the selector selects the switched character.
In this embodiment, when a user needs to input on the display device, the display device receives an instruction input by the user through the control device, and the display device may display an interface as shown in fig. 2A, for example, where the interface shown in fig. 2A includes: an input method keypad 401, and a selector 402 for indicating that a character in the keypad 4011 is selected. As shown in fig. 2A, the interface may further include other items, for example, an identification box 403 for indicating a confirmation search, a text input box 404 for displaying input text content, a cursor 4041 in the text input box 404, a signal strength identification of the wireless network, time information, date, a return home page icon, recommended content (not shown in fig. 2A) associated with characters input by the user, and the like, and the embodiment of the present application is not limited to other items in the GUI400 except for the input method software keyboard zone 401, the text input box 404, and the identification box 403 for indicating a confirmation search.
Then, the user moves the position of the selector 402 in the input method software keyboard area 401 by physical keys on the control device, such as the "up" key, the "down" key, the "left" key, the "right" key, and the "ok" key.
If the user presses the "up" key in the pressure control means, the display device acquires the current key position of the selector 402 and the direction of character switching (i.e., the direction in which the selector 402 moves), and if the current key position of the selector 402 is located in the uppermost row (the position shown in fig. 2B) of the input method software keyboard region 401, the display device controls the selector 402 not to move.
Alternatively, if the current key position of the selector 402 is located in the uppermost row (the position shown in fig. 2B) of the input method software keyboard area 401 and the character switching instruction instructs the selector 402 to move upward, the display device may control the selector 402 to move to the last row, i.e., the fourth row of the input method software keyboard area 401. Wherein, if the selector 402 is located at the position shown in fig. 2B, since the value of the current key position column of the selector 402 is equal to the total column number of the last row (i.e. the fourth row), after the display device receives the character switching instruction of moving upwards, it is determined that the column number of the selector 402 is not changed, the row number is added to 3, and the selector 402 is controlled to move to the sixth row, i.e. the key value index of the key position after moving is keyboard _ layout _ number [3] [5 ]. If the current key of the selector 402 is located in the ninth column of the top row of the input method software keyboard zone 401, the key value index is keyboard _ layout _ number [0] [8], since the value of the current key column of the selector 402 is greater than the total column number of the last row (i.e. the fourth row), after the display device receives the character switching instruction of moving upwards, it is determined that the column number of the selector 402 is changed to the last column of the last row, the row number is added to 3, and the selector 402 is controlled to move to the sixth column of the fourth row, that is, the key value index of the moved key is keyboard _ layout _ number [3] [5 ]. In this way, the speed of moving to the target character can be increased.
If the current key position of the selector 402 is any key position of the second row, the third row or the fourth row, the user presses the "up" key in the pressure control device, the display device determines the size between the numerical value of the column corresponding to the key value index of the key position where the selector 402 is currently located and the total column number of the key positions of the last row, and determines the key position after the selector 402 is moved according to the comparison result, such as fig. 2C and 2D, and fig. 2E and 2F, which is not repeated here.
If the user presses the "down" key in the pressure control means, the display device obtains the current key position of the selector 402 and the direction of character switching (i.e., the direction in which the selector 402 moves), and if the current key position of the selector 402 is located in the last row (the position shown in fig. 2G) of the input method software keyboard region 401, the display device controls the selector 402 not to move.
Alternatively, if the current key position of the selector 402 is located in the last row (position shown in fig. 2G) of the input method software keyboard area 401 and the character switching instruction instructs the selector 402 to move downward, the display device may control the selector 402 to move to the uppermost row, i.e., the first row of the input method software keyboard area 401. Wherein, if the selector 402 is located at the position shown in fig. 2G, since the value of the current key position column of the selector 402 is smaller than the total column number of the top row (i.e. the first row), after the display device receives the character switching instruction of moving downwards, it is determined that the column number of the selector 402 is not changed, the row number is decreased by 3, and the selector 402 is controlled to move to the third column of the first row, i.e. the key value index of the key position after moving is keyboard _ layout _ number [0] [2 ]. If the current key position of the selector 402 is located in the last row of the input method software keyboard zone 401 and the numerical value of the current key position column of the selector 402 is greater than the total column number of the top row (i.e., the first row), after the display device receives the character switching instruction of moving downwards, it is determined that the column number of the selector 402 is changed to the last column of the top row, and the row number is reduced by 3. In this way, the speed of moving to the target character can be increased.
If the current key position of the selector 402 is any key position of the first row, the second row or the third row, the user presses the "down" key in the pressure control device, the display device determines the size between the numerical value of the column corresponding to the key value index of the key position where the selector 402 is currently located and the total column number of the key positions of the next row, and determines the key position after the selector 402 is moved according to the comparison result, such as fig. 2H and 2I, fig. 2E and 2I, fig. 2J and 2F, and fig. 2C and 2K, which is not described again here.
If the user presses the "left" key in the pressure control means, the display device obtains the current key position of the selector 402 and the direction of character switching (i.e., the direction in which the selector 402 moves), and if the current key position of the selector 402 is located in the front row (the position shown in fig. 2L) of the input method software keyboard region 401, the display device controls the selector 402 not to move.
Alternatively, if the current key position of the selector 402 is located in the first column (e.g., the position shown in fig. 2L) of the input method soft key pad area 401 and the character switching instruction instructs the selector 402 to move to the left, the display device may control the selector 402 to move to the last column of the row, i.e., the ninth column of the third row of the input method soft key pad area 401, with the key value index of keyboard _ layout _ number [2] [8 ]. In this way, the speed of moving to the target character can be increased.
If the current key position of the selector 402 is at the key position in any column in the middle of the row, the user presses the "left" key in the pressure control device, and the display device controls the selector 402 to move one column to the left in the current row, for example, fig. 2C and fig. 2M, which is not described again here.
If the user presses the "right" key in the pressure control means, the display device obtains the current key position of the selector 402 and the direction of character switching (i.e., the direction in which the selector 402 moves), and if the current key position of the selector 402 is located in the last column (the position shown in fig. 2E) of the input method software keyboard region 401, the display device controls the selector 402 not to move.
Alternatively, if the current key position of the selector 402 is located in the last column (e.g., the position shown in fig. 2E) of the input method software keyboard area 401 and the character switching instruction instructs the selector 402 to move rightward, the display device may control the selector 402 to move to the foremost column of the row, i.e., the first column of the third row of the input method software keyboard area 401, with the key value index of keyboard _ layout _ number [2] [0 ]. In this way, the speed of moving to the target character can be increased.
If the current key position of the selector 402 is at the key position in any column in the middle of the row, the user presses the "right" key in the pressure control device, and the display device controls the selector 402 to move to the right by one column in the current row, for example, fig. 2C and fig. 2N, which is not described again here.
