Description

Title of Invention : ELECTRONIC DEVICE FOR PROVIDING PREDICTIVE WORD AND OPERATING METHOD THEREOF

Technical Field

[1]
The disclosure relates to an electronic device for providing a predictive word to a user by using letters input by the user, and an operating method thereof.

Background Art

[2]
A portable electronic device such as a smart phone is not limited to basic services, including a telephone call, text transmission, and the like, in providing services, but provides a user with various services, including financial services such as purchase of a product, entertainment services such as games, and the like. Accordingly, a portable electronic device includes various elements, including an input/output interface (e.g., a virtual keyboard displayed on a display), a biometric sensor (e.g., a fingerprint sensor), and the like, configured to acquire information of a user who is using the electronic device or acquire information from the user.
[3]
Among schemes for acquiring information input by the user, the most universal scheme is to acquire character data input by the user through a keyboard. For example, when the user converses with one or more friends via a messenger, the user may use a virtual keyboard displayed on the display of the electronic device. As another example, when the user inputs an address of a webpage or inputs personal identification information in order to use a financial service, or when the user makes note of a thought struck the user, the user may use the virtual keyboard displayed on the display of the electronic device.
[4]
Further, for the convenience of the user, when the user inputs a partially-misspelled word, the electronic device automatically corrects the error, or even when the user inputs only a part of an entire word, the electronic device predicts the entire word and provides the predicted entire word.
[5]
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

Solution to Problem

[6]
When an electronic device provides a predictive word, in relation to a portable electronic device, the portable electronic device has a limited display space, and thus it is difficult for the portable electronic device to provide all predictive words to a user in most cases. The electronic device may determine a word to be provided to the user among the predicted words, on the basis of the current context (e.g., a predictive word class derived from a position in a sentence) and an input history of the user (e.g., whether a relevant word is a word previously input by the user).
[7]
However, the word intended by the user cannot be clearly predicted by utilizing only the input history of the user or the current context. For example, even when the input history of the user or the current context is utilized, 100 or more words can be predicted, and three to five words, which are very few words among the 100 or more words, may be provided to the user. In most cases, a user who cannot trust the provided predictive words manually inputs all letters of a word despite the inconvenience.
[8]
Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide a method for providing a predictive word to a user on the basis of the length of a word desired to be input by the user, and an electronic device therefor.
[9]
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.
[10]
In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device includes a touch-screen display, at least one processor configured to be operatively connected to the touch-screen display, and a memory configured to be operatively connected to the at least one processor, wherein the memory is configured to store instructions that, when executed, cause the at least one processor to control the touch-screen display to display a user interface including a text input area and a keyboard, on the touch-screen display, receive a first input through the keyboard, the first input including a part of a word, in response to the first input, predict at least one word based on at least a portion of the part of the word, the at least one word including a length in a selected range, control the touch-screen display to display the at least one word on the touch-screen display, receive a second input for selecting one word among the at least one word through the touch-screen display, and allow the selected word to be displayed on the text input area.
[11]
In accordance with another aspect of the disclosure, an operating method of an electronic device is provided. The operating method includes displaying a user interface including a text input area and a keyboard, on a touch-screen display, receiving a first input through the keyboard, the first input including a part of a word, in response to the first input, predicting at least one word based on at least a portion of the part of the word, the at least one word including a length in a selected range, displaying the at least one word on the touch-screen display, receiving a second input for selecting one word among the at least one word through the touch-screen display, and displaying the selected word on the text input area.
[12]
An electronic device according to various embodiments provides a user with only a predictive word having a length in a designated range, on the basis of the user's input of a part of a word, and thus can provide a predictive word which more accurately reflects a user's intention.
[13]

For example, as disclosed in FIG. 2, the touch-screen display 210 may display a user interface (e.g., the virtual keyboard 220, a text input area 230, and a candidate word display area 240) configured to converse with another user (e.g., David).
[64]
In an embodiment, the text input area 230 may be an area for display of text determined on the basis of a user input through the virtual keyboard 220. The user may input a content (e.g., text) in the text input area 230 through an interface, such as the virtual keyboard 220. The user may display the text, displayed in the text input area 230, in a conversation content display area 250 or may delete the text without displaying the text in the conversation content display area 250. When any time point is configured as a reference time point, the user may complete an input of a finished word (e.g., "company") in the text input area 230, but may not complete the input of the finished word. For example, the user may input only a part (e.g., "com") of the finished word. In this example, the electronic device 200 may display one or more candidate words, predicted to be input by the user, in the candidate word display area 240 on the basis of a user input (hereinafter, a "first input") corresponding to an input of only a part of the finished word. For example, when the user inputs "com" as a part of the finished word, the electronic device 200 may display three candidate words (e.g., "come", "communication", and "common") starting with "com", in the candidate word display area 240.
[65]
In an embodiment, a display position and a display shape of the candidate word display area 240 may be variously implemented. As disclosed in FIG. 2, the candidate word display area 240 may be displayed between the text input area 230 and the virtual keyboard 220, or may be displayed between the text input area 230 and the conversation content display area 250. The size of the candidate word display area 240 may be changed according to the number of candidate words to be displayed. The candidate word display area 240 may also be configured such that a separate interface, such as a scroll bar, is added thereto instead of fixing the size thereof.
[66]
In an embodiment, the virtual keyboard 220 may be fixedly displayed, at least temporarily, on the screen. For example, the virtual keyboard 220 may be displayed in response to detection of a user input displayed in the text input area 230. As another example, display of the virtual keyboard 220 may be limited in response to detection of a user input for displaying a content (e.g., text), displayed in the text input area 230, in the conversation content display area 250.
[67]
In an embodiment, the virtual keyboard 220 may be implemented as multiple pages respectively corresponding to different languages. For example, the virtual keyboard 220 may be implemented as a first page corresponding to English and a second page corresponding to Korean.
[68]
As can be noted in FIG. 2, when the user inputs only "com", lengths of one or more candidate words provided by the electronic device 200 may not be specified. For example, the electronic device 200 may not only provide a candidate word including four letters (e.g., come), but may also provide a candidate word including six letters (e.g., common) and even a candidate word including 13 letters (e.g., communication). When the lengths (or a range of lengths) of candidate words are not specified as described above, there are a large number of candidate words (e.g., words starting with "com") provided by the electronic device 200, and thus it is unusual in practice to immediately provide the user with a word desired to be input by the user. Hereinafter, a description will be made of a specific embodiment in which the electronic device 200 specifies a length (or a range of a length) of a word on the basis of a user input (e.g., a first input or a separate input distinguished from the first input) and provides a user with one or more candidate words determined on the basis of the specified length (or the specified range of the length).
[69]
FIG. 3 is a block diagram illustrating a configuration of an electronic device according to an embodiment of the disclosure.
[70]
In an embodiment, the electronic device 200 may include a processor 310, a display 320, an input/output interface 330, and a memory 340.
[71]
In an embodiment, the display 320 may be the touch-screen display 210 disclosed in FIG. 2. The display 320 may display at least one content (e.g., a user interface). For example, the display 320 may display a user interface including a text input area (e.g., the text input area 230 of FIG. 2) and a keyboard (e.g., the virtual keyboard 220 of FIG. 2). The display 320 may receive a touch input from a user. For example, the display 320 may receive a first input of the user which allows not a whole of a word but a part thereof (hereinafter, a "first content") to be displayed (or input) in the text input area 230 through the keyboard 220. In an embodiment, the first content itself may constitute one word. For example, when the first content is "come", "come" itself is one word, but may also be a part of another word (e.g., "comet"), and thus may be an example of the first content of the disclosure.
[72]
In an embodiment, the input/output interface 330 may include an input interface configured to receive data as input from the user, and an output interface configured to provide the user with data or a content. The input/output interface 330 may be the interface 177 disclosed in FIG. 1. Although illustrated as separate units, the display 320 may be an example of an input/output interface. The input/output interface 330 may include an input interface such as a keyboard (e.g., a physical keyboard or a virtual keyboard) configured to receive text as input from the user, or a mouse, or an output interface such as a speaker or a vibration output apparatus.
[73]
In an embodiment, the memory 340 may be the memory 130 disclosed in FIG. 1. In an embodiment, the memory 340 may store instructions which cause the electronic device 200 to perform one or more operations according to an embodiment under the control of the processor 310. For example, the memory 340 may store instructions which cause the processor 310 to predict at least one candidate word on the basis of at least a part of a first content in response to a first input.
[74]
In another embodiment, the memory 340 may also store historical data about previous input by the user (e.g., word data input, in the past, by the user in the text input area 230).
[75]
In still another embodiment, the memory 340 may store a database of words (or a combination of one or more words) so as to allow prediction of at least one word on the basis of at least a part of a first content.
[76]
In an embodiment, the processor 310 may generally control an operation of the electronic device 200. The processor 310 may identify a user input received as input through the input/output interface 330, and may process a corresponding command (e.g., may execute a corresponding application) or may control the display 320 to display a corresponding screen. For example, the processor 310 may predict at least one word on the basis of at least a part of a first content in response to reception of a first input, and may control the display 320 to display the predicted at least one word. Although not illustrated, the processor 310 may separately include a word prediction module (not illustrated), and the word prediction module (not illustrated) may receive data on at least a part of a first content, and may store instructions for prediction of at least one word on the basis of the received data and a particular length range.
[77]
FIG. 4 illustrates a flow 400 of operations of providing a predictive word by an electronic device according to an embodiment of the disclosure.
[78]
Referring to FIG. 4 may be performed by the electronic device 200 of FIG. 2 under the control of the processor 310 of FIG. 2. Hereinafter, the electronic device 200 will be described as performing the operations disclosed in FIG. 4.
[79]
In operation 410, the electronic device 200 may display (or provide) a user interface including a text input area (e.g., the text input area 230 of FIG. 2) and a keyboard (e.g., the virtual keyboard 220 of FIG. 2). The electronic device 200 may display a user interface in response to a user input or satisfaction of a pre-configured condition. For example, the electronic device 200 may display a user interface including a text input area and a keyboard, on a display (e.g., the display 320 of FIG. 3) in response to a user input for activation of a messenger application (e.g., execution of a messenger application or display of the same in the foreground).
[80]
In operation 420, the electronic device 200 may receive a first input for input of a first content. The electronic device 200 may receive a first input for input of a first content in the text input area 230. The first input may be input through the keyboard 220. The first content may be not a whole of a word but a part thereof. For example, the first content may be "com" which is a part of "communication".
[81]
In operation 430, the electronic device 200 may predict at least one word. The electronic device 200 may predict at least one word on the basis of at least a part of the first content. For example, the electronic device 200 may predict at least one word including a whole of the first content. In this example, the electronic device 200 may predict at least one word starting with the first content. For example, when the first content is "com", the electronic device 200 may predict at least one word starting with "com" (e.g., "communication"). As another example, the electronic device 200 may also predict at least one word including not the whole of the first content but a part thereof.
[82]
In an embodiment, the electronic device 200 may predict at least one word on the basis of at least a part of the first content and a particular length range. The electronic device 200 may specify a length range by using an input characteristic of the first input or a separate input distinguished from the first input, and may predict at least one word on the basis of the specified length range and at least a part of the first content. Specific embodiments will be disclosed with reference to FIG. 5 to FIGS. 8A, 8B, 8C, and 8D.
[83]
In operation 440, the electronic device 200 may display the at least one word. For example, the electronic device 200 may display the at least one word (e.g., "communication", "common", and "come") predicted in operation 430 in a candidate word display area (e.g., the candidate word display area 240 disclosed in FIG. 2).
[84]
In operation 450, the electronic device 200 may receive a second input for selection of one of the at least one word. For example, the electronic device 200 may receive a second input for selection of one (e.g., "communication") of the at least one word (e.g., "communication", "common", and "come") displayed in the candidate word display area 240.
[85]
In operation 460, the electronic device 200 may display the selected word in the text input area 230. For example, the electronic device 200 may replace the first content, displayed in the text input area 230, by the selected word, and may display the selected word, by which the first content is replaced, in the text input area 230.
[86]
FIG. 5 illustrates a flow of specific operations of predicting at least one word by an electronic device according to an embodiment of the disclosure.
[87]
Referring to FIG. 5, FIG. 5 may be specific operations of operation 430 disclosed in FIG. 4.
[88]
In operation 510, the electronic device 200 may provide a user interface configured to specify a length range.
[89]
In an embodiment, the electronic device 200 may provide a user interface configured to specify a length range in the text input area 230, or may provide a user interface configured to specify a length range outside the text input area 230 (e.g., between the text input area 230 and the conversation content display area 250).
[90]
In an embodiment, the electronic device 200 may provide a user interface configured to specify a length range, regardless of whether a content is displayed (or input) in the text input area 230. For example, the electronic device 200 may provide a user interface including the text input area 230 and the keyboard, and simultaneously, may provide a user interface configured to specify a length range. In another embodiment, only when a content is displayed in the text input area 230, the electronic device 200 may provide a user interface configured to specify a length range. For example, when the text input area 230 is blank, the electronic device 200 does not provide a user interface configured to specify a length range, but when a content (e.g., at least one letter) is displayed (or input) in the text input area 230, may provide the user interface configured to specify a length range.
[91]
In an embodiment, a user interface configured to specify a length range may include two or more icons (or buttons) corresponding to different length ranges (e.g., a first range or a second range which is not included in the first range). For example, the user interface configured to specify a length range may include an S icon corresponding to a short length, an M icon corresponding to a medium length, and an L icon corresponding to a long length. The electronic device 200 may separately provide an interface through which a user can set the number of letters corresponding to each of a short length, a medium length, and a long length. For example, the electronic device 200 may receive the user's configuration which causes a short length corresponding to the S icon to correspond to six letters or less with reference to an alphabet.
[92]
In operation 520, the electronic device 200 may determine a length range on the basis of a user input entered through the provided user interface. For example, the electronic device 200 may determine a length range as 6 or less with reference to the number of letters, in response to detection of a user input for selection of the S icon. As another example, the electronic device 200 may determine a length range as 7-9 inclusive with reference to the number of letters, in response to detection of a user input for selection of the M icon.
[93]
In operation 530, the electronic device 200 may predict at least one word on the basis of the determined length range and at least a part of the first content. In an embodiment, the electronic device 200 may extract at least one word including at least a part of the first content (or starting with at least a part of the first content) from among multiple words belonging to the determined length range. In another embodiment, the electronic device 200 may extract at least one word belonging to the determined length range from among multiple words including at least a part of the first content (or starting with at least a part of the first content). For example, the electronic device 200 may determine "come" and "common", the number of letters of each of which is 6 or less, among the multiple words ("come", "communication", and "common") including at least a part of the first content.
[94]
FIG. 6A illustrates a user interface provided by an electronic device according to various embodiments, FIG. 6B illustrates a user interface provided by an electronic device according to various embodiments, FIG. 6C illustrates a user interface provided by an electronic device according to various embodiments, and FIG. 6D illustrates a user interface provided by an electronic device according to various embodiments.
[95]
Referring to FIG. 6A, the electronic device 200 may display a user interface including the text input area 230 and the keyboard 220. The electronic device 200 may detect, through the keyboard 220, a first input for display of a first content ("com") in the text input area 230, and may display the first content in the text input area 230.
[96]
When the electronic device 200 detects that a part (e.g., "c") of the first content ("com") is displayed in the text input area 230, the electronic device 200 may provide a user interface configured to specify a length range. The user interface configured to specify a length range may include multiple icons 232, 234, and 236 respectively corresponding to different lengths (or the number of letters). The electronic device 200 may display the multiple icons 232, 234, and 236 in the text input area 230, for example, at a right end part of the text input area 230.
[97]
In an embodiment, the electronic device 200 may display the candidate word display area 240 between the text input area 230 and the keyboard 220. Even when a user input entered through the user interface configured to specify a length range is not detected, the electronic device 200 may display at least one word in the candidate word display area 240. For example, the electronic device 200 may display at least one word (e.g., "come", "communication", and "common"), which starts with the first content ("com") and is displayed in the text input area 230, in the candidate word display area 240.
[98]
In an embodiment, the electronic device 200 may receive (or detect) a user input for one of (or for selection one of) the multiple icons 232, 234, and 236. For example, the electronic device 200 may receive a user input for the S icon 232.
[99]
Referring to FIG. 6B, the electronic device 200 may change display of the selected icon 232 in response to reception (or detection) of the user input for one of (or for selection one of) the multiple icons 232, 234, and 236. For example, the electronic device 200 may display an S icon 233 having an oblique-line pattern added thereto.
[100]
In an embodiment, in response to reception of a user input for one of the multiple icons 232, 234, and 236, the electronic device 200 may predict at least one word, and may display the same in the candidate word display area 240. The electronic device 200 may determine a length range corresponding to the selected icon (e.g., the S icon 232), and may predict at least one word on the basis of the determined length range and at least a part of the first content. For example, the electronic device 200 may determine a length range (6 or less with reference to the number of letters) corresponding to the selected S icon 232, may determine at least one word (e.g., "comedy", "commit", and "common") which starts with the first content and is in the determined length range, and may display the determined word in the candidate word display area 240. In an embodiment, the electronic device 200 may display at least one word (or a word list) in a case where at least some words (e.g., "common") coincide with a word list having been displayed in the candidate word display area 240 before the S icon 232 is selected. In another embodiment, the electronic device 200 may display at least one word (or a word list) in a case where at least some words do not coincide with a word list having been displayed in the candidate word display area 240 before the S icon 232 is selected.
[101]
Referring to FIG. 6C, the electronic device 200 may receive a user input (hereinafter, a "second input") for selection of one word from among at least one word displayed in the candidate word display area 240. For example, the electronic device 200 may receive a second input for selection of one word (e.g., "commit") from among at least one word (e.g., "comedy", "commit", and "common") displayed in the candidate word display area 240.
[102]
Referring to FIG. 6D, the electronic device 200 may display the selected word in the text input area 230 in response to detection of the second input for selection of one word from among the at least one word. For example, the electronic device 200 may display the selected word ("commit") instead of the first content ("com") in the text input area 230 in response to detection of a second input for selection of "commit" from among the at least one word.
[103]
In an embodiment, the electronic device 200 may not display a user interface configured to specify a length range, in response to detection of the second input or in response to display of the selected word in the text input area 230. Although not illustrated, even after the selected word is displayed in the text input area 230, the electronic device 200 may maintain display of the user interface configured to specify a length range.
[104]
In an embodiment, the electronic device 200 may not display a candidate word display area in response to detection of the second input or in response to display of the selected word in the text input area 230. Although not illustrated, even after the selected word is displayed in the text input area 230, the electronic device 200 may maintain display of the candidate word display area.
[105]
FIG. 7 illustrates a flow of specific operations of predicting at least one word by an electronic device according to an embodiment of the disclosure.
[106]
Referring to FIG. 7, FIG. 7 may be specific operations of operation 430 disclosed in FIG. 4.
[107]
In operation 710, the electronic device 200 may verify an input characteristic of at least a part of the first input. For example, the electronic device 200 may verify an input characteristic of at least a part of the first input (when the first input includes multiple inputs, the last input element, for example, when the first content is "com", an input through a key corresponding to "m" in the keyboard 220) for input of the first content (e.g., "com") in the text input area 230.
[108]
In an embodiment, an input characteristic may include at least one of a time for which an input is maintained, the touch area of the input, a body part causing the input (e.g., skin or nail), and the type of input (or gesture) (e.g., tap, tap and hold, or double tap).
[109]
In operation 720, the electronic device 200 may determine a length range on the basis of the verified input characteristic.
[110]
In an embodiment, the electronic device 200 may determine (or specify) a length range according to a time for which an input is maintained. For example, when at least a part (e.g., an input through a key corresponding to "m" in the keyboard 220) of the first input is continuously maintained for a predetermined first time (e.g., 1.2 sec) or longer, the electronic device 200 may specify a length range (e.g., 10 or more with reference to the number of letters) identically to a case in which the L icon 236 is selected in FIG. 6A. As another example, when at least a part (e.g., an input through a key corresponding to "m" in the keyboard 220) of the first input is not continuously maintained for a predetermined second time (e.g., 0.6 sec) or longer, the electronic device 200 may specify a length range (e.g., 6 or less with reference to the number of letters) identically to a case in which the S icon 232 is selected in FIG. 6A. As still another example, when at least a part of the first input is maintained for the predetermined second time to the predetermined first time inclusive, the electronic device 200 may specify a length range (e.g., 7-9 inclusive with reference to the number of letters) identically to a case in which the M icon 234 is selected in FIG. 6A.
[111]
In an embodiment, the electronic device 200 may also determine a length range according to a body part performing an input. For example, when at least a part (e.g., an input through a key corresponding to "m" in the keyboard 220) of the first input is performed using the user's nail, the electronic device 200 may specify a length range (e.g., 10 or more with reference to the number of letters) identically to a case in which the L icon 236 is selected in FIG. 6A.
[112]
In operation 730, the electronic device 200 may predict at least one word on the basis of the determined length range and at least a part of the first content. The electronic device 200 may determine at least one word (e.g., "commitment", "complement", and "compliance") which is in the determined length range (e.g., 10 or more with reference to the number of letters) and starts with the first content ("com").
[113]
FIGS. 8A, 8B, 8C and 8D illustrate a user interface provided by an electronic device on the basis of an input characteristic of a user input according to various embodiments of the disclosure.
[114]
Referring to FIG. 8A, the electronic device 200 may display the text input area 230, the keyboard 220, and the multiple icons 232, 234, and 236 respectively corresponding to different lengths.
[115]
The electronic device 200 may detect a tap-and-hold input through a key corresponding to "m" in the keyboard 220, in a state where "co" is input in the text input area 230.
[116]
Referring to FIG. 8B, in response to detection of the tap-and-hold input through the key corresponding to "m" in the keyboard 220, the electronic device 200 may add "m" in the text input area 230 in which "co" is input, and simultaneously, may display an L icon 237 having an oblique-line pattern added thereto, as in a case in which the L icon 236 is selected. Further, the electronic device 200 may display at least one word (e.g., "commitment", "complement", and "compliance"), which is in a length range corresponding to the L icon 236 and starts with a first content ("com") displayed in the text input area 230, in the candidate word display area 240.
[117]
In an embodiment, multiple icons corresponding to different lengths may be arranged in the keyboard 220.
[118]
Referring to FIG. 8C, the electronic device 200 may display multiple icons 802, 804, and 806 corresponding to different lengths in a designated area (e.g., an uppermost left part) of the keyboard 220.
[119]
In an embodiment, the electronic device 200 may detect a user input for the L icon 806 displayed in a designated area of the keyboard 220, in a state where "com" is displayed in the text input area 230 and "come", "communication", and "common" are displayed in the candidate word display area 240. In this example, as illustrated in FIG. 8D, the electronic device 200 may display "commitment", "complement", and "compliance" in the candidate word display area 240, and may display the L icon 807 having an oblique-line pattern added thereto.
[120]
FIGS. 9A, 9B and 9C illustrate a change in a user interface provided by an electronic device in response to a user input according to various embodiments of the disclosure.
[121]
Referring to FIG. 9A, the electronic device 200 may display the text input area 230, the keyboard 220, and the multiple icons 232, 234, and 236 respectively corresponding to different lengths. The electronic device 200 may detect a user input for selection of the S icon 232, in a state where "com" is input in the text input area 230.
[122]
Referring to FIG. 9B, in response to detection of the user input for selection of the S icon 232, the electronic device 200 may display an S icon 233 having an oblique-line pattern added thereto, and simultaneously, may display, in the candidate word display area 240, at least one word (e.g., "comedy", "commit", and "common") which is in a length range (e.g., 6 or less with reference to the number of letters) corresponding to the S icon 232 and starts with a first content ("com") displayed in the text input area 230.
[123]
In an embodiment, in a state where the at least one word, which is in the length range corresponding to the S icon 232 and starts with the first content ("com") displayed in the text input area 230, is displayed in the candidate word display area 240, the electronic device 200 may receive a user input for changing a length range, instead of a second input for selection of one of the at least one word displayed in the candidate word display area 240. For example, the electronic device 200 may receive a user input for selection of the M icon 234.
[124]
Referring to FIG. 9C, in response to reception of the user input for selection of the M icon 234, the electronic device 200 may display the S icon 232 obtained by removing the oblique-line pattern, and may display an L icon 235 having an oblique-line pattern added thereto. Further, the electronic device 200 may display, in the candidate word display area 240, at least one word (e.g., "complete", "component", and "comprise") which is in a length range corresponding to the M icon 234 and starts with a first content ("com") displayed in the text input area 230, instead of at least one word (e.g., "comedy", "commit", and "common") which is in a length range corresponding to the S icon 232.
[125]
According to the embodiment disclosed in FIGS. 9A, 9B, and 9C, even when a user makes a mistake in selecting a desired icon, the electronic device 200 allows the user to easily reselect a desired icon.
[126]
FIGS. 10A and 10B illustrate a change in a user interface provided by an electronic device in response to a user input according to various embodiments of the disclosure.
[127]
Referring to FIG. 10A, the electronic device 200 may display the text input area 230, the keyboard 220, the candidate word display area 240, and multiple icons 231, 234, and 236 respectively corresponding to different lengths. In this regard, since the S icon 231 is deactivated differently from the M icon 234 and the L icon 236 which are activated, a user may not enter an input for the S icon 231.
[128]
The S icon 231, which is deactivated differently from the M icon 234 and the L icon 236, may be caused by the length of a first content input in the text input area 230. For example, when the first content input in the text input area 230 is "commit" and has a length of 6 with reference to the number of letters, the deactivated S icon 231 may be displayed. This is because a length range corresponding to the S icon 231 is 6 or less with reference to the number of letters and there is a low possibility that the user will input a word, the length of which is in the length range corresponding to the S icon 231.
[129]
Although not illustrated, the deactivated S icon 231 may be displayed only when a first content, the length of which exceeds the length range corresponding to the S icon 231, (e.g., text, the number of letters of which is 7 or more) is input in the text input area 230.
[130]
In an embodiment, the electronic device 200 may detect a user input for selection of the M icon 234 from among the M icon 234 and the L icon 236 which are activated.
[131]
Referring to FIG. 10B, the electronic device 200 may determine at least one word ("committed", "committer", and "committee") which has a length belonging to a length range (e.g., 7-9 inclusive with reference to the number of letters) corresponding to the M icon 234 and starts with the first content ("commit"), and display the same in the candidate word display area 240. In response to detection of a user input for selection of the M icon 234, the electronic device 200 may display the M icon 235 having an oblique-line pattern added thereto.
[132]
FIGS. 11A, 11B and 11C illustrate a user interface provided by an electronic device on the basis of some of letters input by a user according to various embodiments of the disclosure.
[133]
Referring to FIG. 11A, the electronic device 200 may display the text input area 230, the keyboard 220, the candidate word display area 240, and the multiple icons 232, 234, and 236 respectively corresponding to different lengths. A first content ("Adnte") is input (or displayed) in the text input area 230, and at least one word (e.g., "advantage", "adventure", and "advertise") including at least a part of the first content may be displayed in the candidate word display area 240. In the word displayed in the candidate word display area 240, the letters constituting the first content do not need to be arranged in the same order as that of the first content. For example, "advantage" displayed in the candidate word display area 240 includes all the letters (a, d, n, t, and e) constituting the first content ("adnte"), but is neither consecutive in the same manner as in the first content, nor is arranged in the same order as that of the first content. The word (e.g., "advertise") displayed in the candidate word display area 240 does not need to include all the letters constituting the first content.
[134]
Referring to FIG. 11A, the at least one word displayed in the candidate word display area 240 may not start with the first content, and may not include the entire first content as a part of the word. This is because no word starting with the first content exists, or no word including the entire first content as a part thereof exists, and the fundamental reason is because the first content ("adnte") is input due to a typographical error by the user.
[135]
When the first content ("adnte") is input due to a typographical error by the user as described above, the electronic device 200 may not specify which letter corresponds to the typographical error in the first content. Therefore, the number of words to be displayed in the candidate word display area 240 may be very large. Any letter constituting the first content may be mistakenly inserted, or any letter constituting the first content may be input instead of a letter intended to be input by the user. For example, a word (e.g., "adventure") including all the letters constituting the first content ("adnte") may be displayed in the candidate word display area 240, and under the premise that "n" is mistakenly inserted in the first content, a word (e.g., "advertise") including all the remaining letters except for "n" may be displayed in the candidate word display area 240. Therefore, the probability that the word displayed in the candidate word display area 240 will be a word satisfying the original intention of the user may be very low.
[136]
In order to overcome the above-described problems, the electronic device 200 may display the multiple icons 232, 234, and 236 respectively corresponding to different lengths, and may predict at least one word satisfying the user's intention, in response to a user input for one of the icons.
[137]
For example, when a user input for the M icon 234 is detected, Referring to FIG. 11B, the electronic device 200 may determine at least one word (e.g., "andante", "adventure", and "adjective") which belongs to a length range corresponding to the M icon 234 and includes at least a part of the first content, and may display the same in the candidate word display area 240. When a user input for the M icon 234 is detected, the electronic device 200 may display an M icon 235 having an oblique-line pattern added thereto.
[138]
Referring to FIG. 11C, the electronic device 200 may detect a second input for selection of one word (e.g., "adjective") from among the at least one word displayed in the candidate word display area 240, and may display a selected word in the text input area 230.
[139]
The embodiment disclosed in FIGS. 11A, 11B, and 11C relieves the user of the burden of having to input a word with correct spelling.
[140]
FIGS. 12A, 12B, 12C and 12D illustrate a user interface provided by an electronic device on the basis of a word class of a word according to various embodiments of the disclosure.
[141]
Referring to FIG. 12A, the electronic device 200 may display a user interface including the text input area 230 and the keyboard 220. When the electronic device 200 detects, through the keyboard 220, a first input for display of a first content ("com") in the text input area 230, in the text input area 230, the electronic device 200 may display the first content, and may display a user interface configured to specify a length range (e.g., the multiple icons 232, 234, and 236) and a user interface configured to specify a word class (e.g., an N icon 242, a V icon 244, and an Ad icon 246). The N icon 242 may signify a noun, the V icon 244 may signify a verb, and the Ad icon 246 may signify an adjective.
[142]
In an embodiment, even before the electronic device 200 detects the user interface configured to specify a length range or the user interface configured to specify a word class, the electronic device 200 may display at least one word including at least a part of the first content. For example, the electronic device 200 may display words (e.g., "come", "communication", and "common"), of which length ranges or word classes are not specified and which have various length ranges and various word classes, in the candidate word display area 240.
[143]
In an embodiment, the electronic device 200 may detect a user input for the user interface configured to specify a length range and a user input for the user interface configured to specify a word class. For example, the electronic device 200 may detect a user input for selection of the M icon 234 and a user input for selection of the V icon 244.
[144]
In an embodiment, although not illustrated, even when there is no user input for the user interface configured to specify a word class, the electronic device 200 may determine a word class or may reduce a selectable word class candidate group, on the basis of at least a part of the first content (e.g., when the first content is a sentence, the context of the sentence) input in the text input area 230. For example, when the first content input in the text input area 230 ends with a noun, the electronic device 200 may reduce a selectable word class candidate group to a verb and an adjective from among a noun, a verb, and an adjective. When a selectable word class candidate group is a single word class, a word class may be specified.
[145]
Referring to FIG. 12B, the electronic device 200 may change display of icons selected by a user, or may give the selected icons with an effect notifying of selection of the icons by the user. For example, the electronic device 200 may display the M icon 235 having an oblique-line pattern added thereto and the N icon 243 having an oblique-line pattern added thereto.
[146]
In an embodiment, the electronic device 200 may newly display at least one related to the selected icons in the candidate word display area 240. For example, when the M icon 234 and the N icon 242 are selected, the electronic device 200 may display, in the candidate word display area 240, at least one word (e.g., "committee", "command", and "component") which has a length in a length range corresponding to the M icon 234, has a word class corresponding to the N icon 242, and starts with the first content ("com").
[147]
Referring to FIG. 12C, the electronic device 200 may receive a second input for selection of one of the at least one word displayed in the candidate word display area 240. For example, the electronic device 200 may receive a second input for selection of "command".
[148]
Referring to FIG. 12D, the electronic device 200 may display the selected word in the text input area 230. The electronic device 200 may replace the first content ("com"), displayed in the text input area 230, by the selected word ("command"), and may display the selected word in the text input area 230.
[149]
Referring to FIGS. 12A, 12B, 12C, and 12D, the description has been made of an embodiment for providing a predictive word to a user on the basis of a user input for a user interface configured to specify a length (or a range of a length) of a word and a user input for a user interface configured to specify a word class. However, it is also possible to implement an embodiment for providing a predictive word to a user on the basis of only a user input for a user interface configured to specify a word class.
[150]
The embodiment disclosed in FIGS. 12A, 12B, 12C, and 12D allows an improvement in the efficiency of learning of a word in any language.
[151]
FIGS. 13A and 13B illustrate a user interface for configuring a length range corresponding to a particular object according to various embodiments of the disclosure.
[152]
In an embodiment, the user interfaces disclosed in FIGS. 13A and 13B may be provided to a user before the embodiment disclosed in FIG. 4 is implemented. That is, the embodiment disclosed in FIG. 4 may be implemented after a length range corresponding to a particular object (e.g., the S icon 232) is configured according to user inputs entered through the user interfaces disclosed in FIGS. 13A and 13B.
[153]
Referring to FIG. 13A, the electronic device 200 may receive a user's configuration of whether to receive a predictive word-providing service according to an embodiment. For example, the electronic device 200 may provide a user interface 1310 configured to receive a user's configuration of whether to receive a predictive word-providing service, in an individual application (e.g., a messenger application) or in a particular application (e.g., a control panel) for defining an overall configuration or environment of the electronic device 200.
[154]
In an embodiment, when a user input through the user interface 1310 for activation of a length-based predictive word-providing function is detected, as disclosed in FIG. 13B, a user interface for specifically configuring a length range may be additionally provided. When the user interface for specifically configuring a length range is provided, an object or indicator 1320 notifying of activation of the length-based predictive word-providing function may be provided therewith.
[155]
Referring to FIG. 13B, the electronic device 200 may provide the user interface for specifically configuring a length range. The user interface disclosed in FIG. 13B may also be provided in an individual application or in a particular application for defining an overall configuration or environment of the electronic device 200. Through the user interface disclosed in FIG. 13B, the electronic device 200 may help individual users personalize a length range of a word according to each user's need. As described above with reference to the drawings, a user interface configured to specify a length range (e.g., the multiple icons 232, 234, and 236 of FIGS. 6A, 6B, 6C, and 6D) may be provided together with a text input area (e.g., the text input area 230 of FIG. 2). The electronic device 200 may provide a user interface configured to receive a user's configuration of a length range corresponding to one icon among the multiple icons.
[156]
For example, the electronic device 200 may display a lower limit 1331, an upper limit 1335, and an adjustment bar 1333 in order to receive the configuration of a length range corresponding to the S icon 232. For example, when the user moves the adjustment bar 1333 and configures the same as a length of 6, the electronic device 200 may determine that a length range corresponding to the S icon 232 is 6 or less with reference to the number of letters.
[157]
As another example, the electronic device 200 may display a lower limit 1341, an upper limit 1345, and an adjustment bar 1343 in order to receive the configuration of a length range corresponding to the M icon 234. For example, when the user moves the adjustment bar 1343 and configures the same as a length of 9, the electronic device 200 may determine that a length range corresponding to the M icon 234 is 7-9 inclusive with reference to the number of letters. In an embodiment, when the user moves the adjustment bar 1343 and configures the same as a length of 9, the electronic device 200 may determine that a length range corresponding to the M icon 234 is 7-9 inclusive with reference to the number of letters, and that a length range corresponding to the L icon 236 is 9 (as indicated by reference numeral 1351) or more with reference to the number of letters.
[158]
In an embodiment, the electronic device 200 may set a lower limit or an upper limit (e.g., the upper limit 1335) to have different values according to types of languages. For example, when a default language is changed from English to Korean or Chinese, the electronic device 200 may reduce the value of the lower limit or the upper limit on the basis of a designated difference or a designated ratio. This is because the number of letters constituting a word in Korean or Chinese is less than in English.
[159]
In an embodiment, when the user interface disclosed in FIG. 13B is provided in an individual application (e.g., a messenger application), the electronic device 200 may automatically recognize a language of a first content input in the text input area 230, and may determine (or change) a value of a lower limit or an upper limit on the basis of the recognized language. For example, in a state in which a length range corresponding to the S icon 232 is configured as 6 or less with reference to the number of letters, when the user inputs a first content in Korean rather than English in the text input area 230, the electronic device 200 may reduce a length range (e.g., 4 or less with reference to the number of letters) corresponding to the S icon 232 by a designated ratio.
[160]
While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
