[0030] The present invention will be described in detail below in conjunction with the accompanying drawings, and the features of the present invention will be further revealed in the following specific description.

[0031] The following detailed description refers to the accompanying drawings showing exemplary embodiments of the present invention. However, the scope of the present invention is not limited to these embodiments, but is defined by the appended claims. Therefore, embodiments other than those shown in the drawings, such as modified versions of the illustrated embodiments, are still encompassed by the present invention.

[0032] References in this specification to "one embodiment," "an embodiment," "an example embodiment," etc., mean that the embodiment may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Furthermore, these phrases do not necessarily refer to the same embodiment. Furthermore, when a particular feature, structure, or characteristic is described in conjunction with an embodiment, it should be understood that the particular feature, structure, or characteristic can be implemented in conjunction with other embodiments within the knowledge of a person skilled in the relevant art, whether or not explicitly described.

[0033] For ease of explanation, this document only describes in detail an embodiment in which the technical solution of the present invention is applied to a "vehicle", but those skilled in the art can fully understand that the technical solution of the present invention can be applied to any means of transportation such as trains, subways, ships, etc. where there may be a meeting of vehicles. Unless otherwise specified, the term "A or B" used in this specification refers to "A and B" and "A or B", rather than A and B being exclusive.

[0034] In the context of the present invention, the "user" may refer to the driver, and may also refer to passengers other than the driver sitting in the vehicle, such as a passenger in the front passenger seat and / or a rear passenger.

[0035] Figure 1A The layout diagram of the input interface including the single ring keyboard in the prior art is shown, and Figure 1B A layout diagram of an input interface including a dual-ring keyboard according to an embodiment of the present invention is shown.

[0036] BMW has developed a different input control hardware from the touch control, the ZBE controller, which is a push-button rotary button installed next to the driver's seat. Users can use the ZBE controller to interact with the CID, such as inputting characters. Compared with the CID, the ZBE controller is closer to the driver, and its operation has only two simple steps, namely "press the button" and "rotate the button", which makes driving safer and input to the touch screen more convenient.

[0037] like Figure 1A As shown, currently, the Chinese speller GUI design for the ZBE controller is a single ring on which 26 letter keys and some function keys are displayed at certain intervals. Specifically, refer to Figure 1A, the input interface includes an input area, a candidate area, and a keyboard area. The input area displays the characters that have been input, such as the confirmed characters and the unconfirmed characters that have not been fully spelled. The candidate area includes candidate characters / words corresponding to the current spelling syllable. The keyboard area includes a single-ring keyboard for character input. Characters and function options (such as symbols, confirmation, backspace, language, space, etc.) are displayed on the ring of the single-ring keyboard at certain intervals. This single-ring layout has a drawback that when users input Chinese characters, they have to rotate and press the ZBE controller to sequentially select characters on the ring to input letters one by one to form a complete pinyin, so the input efficiency is low. For example, if a user needs to input the Chinese character "帮", the user needs to select and confirm the four characters "b", "a", "n", and "g" one by one.

[0038] Reference Figure 1B , compared with Figure 1A , the present invention provides a double-ring keyboard 100. The keyboard 100 includes an outer ring 101, an inner ring 102, and a focus area 103. In Figure 1B , it is assumed that Chinese has been selected through the "language" function option, that is, in the scenario of Chinese input.

[0039] Reference Figure 1B , generally, one or more English characters and one or more function options are displayed on the inner ring 102. In the Chinese input scenario, users can select the initial consonants of pinyin from the English characters through the inner ring 102. Compared with Figure 1A , Figure 1B , a "mode" option is added to the function options displayed on the inner ring 102 of . This mode option can be selected to switch between the two Chinese pinyin quick input modes described in this article (i.e., the rhyme association mode and the first stroke screening mode). Those skilled in the art can fully understand that other function options (symbols, confirmation, backspace, language, space, etc.) are only illustrative and are not intended to limit the specific function options included in the inner ring 102. In practice, different function options can be included according to actual needs.

[0040] Continue to refer to Figure 1B , based on the initial consonants input through the inner ring 102, corresponding content can be displayed on the outer ring 101 to facilitate the selection of the desired Chinese characters. For example, in the rhyme association mode, rhyme candidates that conform to the pinyin rules and can be combined with the input initial consonants can be displayed on the outer ring 101. In the first stroke screening mode, one or more first strokes of all candidate characters starting with the input initial consonants can be displayed on the outer ring 101. In the context of this application, "rhyme" can include single vowels, compound vowels, and nasal vowels. Generally, these three categories of vowels include 24 vowels in total.

[0041] According to an embodiment of the present invention, one or more vowel candidates or one or more first strokes may be displayed at intervals in a portion of the outer ring 101 near the selected initial consonant to facilitate user selection. For example, referring to Figure 1B , assuming that the initial consonant "b" in the inner ring 102 is selected, one or more vowel candidates or one or more first strokes may be displayed in a portion of the outer ring 101 near "b" on the inner ring 102.

[0042] Continuing to refer to Figure 1B , the focus area 103 is located within the inner ring 102, that is, the area enclosed by the inner ring 102. This focus area 103 generally displays the character where the current focus is located. For example, when the user traverses the outer ring 101 and / or the inner ring 102 by rotating the ZBE controller, the user's current focus may be prominently displayed (e.g., magnified, highlighted, etc.) in the focus area 103 to facilitate the user to know where the current focus is located without the user having to view the relatively small inner ring 102 and / or outer ring 101.

[0043] The following refers to Figure 2 and Figure 3 to further describe the usage process of two Chinese pinyin quick input modes. Figure 2 and Figure 3 Both take the input of the Chinese character "bang" as an example.

[0044] Figure 2 shows the usage process of the vowel association mode of the double-ring keyboard using Figure 1B according to an embodiment of the present invention.

[0045] In Figure 2 -1, the focus is moved to the initial consonant "b" in the inner ring 102 and confirmed. At this time, the input area at the upper part of the input interface displays "b", and the candidate area on the left displays all Chinese characters with the initial consonant "b". One or more vowels that can be combined with the initial consonant "b" and conform to the pinyin spelling rules are displayed on the outer ring 101. Since the desired Chinese character "bang" is not displayed in the candidate area on the left, it is necessary to continue to select the vowel.

[0046] In Figure 2-2 , the focus is moved to the vowel "ang" in the outer ring 101 and confirmed. At this time, the input area at the upper part of the input interface displays "bang", and the candidate area on the left displays all candidate characters with the syllable "bang". According to an embodiment of the present invention, the outer ring 101 may be hidden after "ang" is confirmed, that is, not displayed.

[0047] In Figure 2-3In [description], the focus is moved to the candidate area, the character "帮" is selected and confirmed. At this time, the Chinese character "帮" is displayed in the upper input area. According to an embodiment of the present invention, after the character "帮" is confirmed, the candidate area on the left can be hidden, that is, not displayed, and the cursor can return to the inner ring 102, for example, return to "b" in the inner ring 102.

[0048] Figure 3 Shows the usage process of the first stroke screening mode of the double-ring keyboard according to an embodiment of the present invention Figure 1B adopted.

[0049] In Figure 3 -1, the focus is moved to the initial consonant "b" in the inner ring 102 and confirmed. At this time, "b" is displayed in the upper input area, all Chinese characters with the initial consonant "b" are displayed in the candidate area on the left, and one or more first strokes of all candidate characters starting with the initial consonant "b" are displayed on the outer ring 101.

[0050] In Figure 3-2 , the focus is moved to the stroke "一" in the outer ring 101 and confirmed. At this time, "b" is still displayed in the upper input area, and one or more candidate characters with the initial consonant "b" and the first stroke being "一" are displayed in the candidate area on the left. According to an embodiment of the present invention, the outer ring 101 can be hidden after the stroke "一" is confirmed, that is, not displayed.

[0051] In Figure 3-3 , the focus is moved to the candidate area, the character "帮" is selected and confirmed. At this time, the Chinese character "帮" is displayed in the upper input area. According to an embodiment of the present invention, after the character "帮" is confirmed, the candidate area on the left can be hidden, that is, not displayed, and the cursor can return to the inner ring 102, for example, return to "b" in the inner ring 102.

[0052] According to an embodiment of the present invention, one or more candidate characters in the candidate area in the above examples can be displayed as a single column, and the candidate characters in this column can be displayed according to sorting rules such as pinyin order, usage frequency, etc. In addition, depending on the number of candidate characters that can be displayed in this column, this column can be traversed up and down (for example, can be scrolled up and down, etc.) to display more candidate characters.

[0053] However, those skilled in the art can fully understand that the display method of candidate characters in the candidate area shown in FIGS. 1-3 is only illustrative and does not constitute a specific limitation on the display method of the candidate area. For example, the number of candidate characters displayed in the current column of the candidate area can also be different according to the specific interface design. And the candidate area can be hidden when there are no candidate characters, that is, not displayed.

[0054] According to another embodiment of the present invention, Figure 2 and Figure 3 The input area in can only display the last selected Chinese character, such as "帮" (bāng), without displaying the initial consonant or the combination of the initial consonant and the final.

[0055] Those skilled in the art can understand that although the present invention combines with the ZBE controller of BMW for selection (e.g., rotating the ZBE controller) and / or confirmation (e.g., pressing the ZBE controller), the input device of the present invention can also be used in combination with other methods. For example, the user can also input Chinese characters and / or perform other operations by touching the input device displayed on the touch screen. For example, the user can rotate the inner ring and / or the outer ring of the input device displayed on the touch screen for traversal, and perform selection and confirmation by touching specific characters, Chinese characters, function areas, and / or strokes. However, this method is recommended to be carried out under the condition of ensuring safety (e.g., when the vehicle is stationary or operated by the co-pilot).

[0056] Those skilled in the art can fully understand that the layout relationships (e.g., spatial position relationships, relative sizes, etc.) of the input area, the candidate area, and the input keyboard in the input interface illustrated in FIGS. 1-3 are only schematic, and different layout methods can be adopted according to actual requirements.

[0057] Figure 4 FIG. shows a flowchart of a method 400 for Chinese input according to an embodiment of the present invention.

[0058] At 405, a selection of an initial consonant is received via the inner ring of the double-ring keyboard in the input interface. According to an embodiment of the present invention, the input interface includes an input area, a candidate area, and the double-ring keyboard. The double-ring keyboard includes an outer ring, an inner ring, and a focus area. Generally, one or more English characters and one or more function options are displayed on the inner ring, and the one or more function options include mode function options that can be selected to switch among multiple Chinese pinyin quick input modes. Contents corresponding to the input initial consonant can be displayed on the outer ring based on the initial consonant input through the inner ring to facilitate the selection of the desired Chinese character. The focus area is located within the inner ring and generally displays the character where the current focus is located. In the context of the present invention, for the sake of convenience of description, the "selection" and "confirmation" of the above-mentioned characters, candidate characters, and / or function options, etc. are simply referred to as "selection".

[0059] At 410, based on the selection of the initial consonant, contents corresponding to the initial consonant are displayed on the outer ring of the double-ring keyboard surrounding the inner ring according to the current Chinese pinyin quick input mode, and one or more candidate Chinese characters starting with the initial consonant are displayed in the candidate area.

[0060] According to an embodiment of the present invention, when the current Chinese Pinyin quick input mode is the vowel association mode, one or more vowels that can be combined with the initial consonant and conform to the Pinyin spelling rules are displayed on the outer ring.

[0061] According to an embodiment of the present invention, when the current Chinese Pinyin quick input mode is the first stroke screening mode, one or more first strokes of the candidate Chinese characters beginning with the initial consonant are displayed on the outer ring.

[0062] At 415 , it is determined whether one or more candidate Chinese characters in the candidate area are selected. If no Chinese character is selected in the candidate area (ie, there is no Chinese character that the user expects to input in the candidate area), the process proceeds to step 420 , otherwise, the process proceeds to step 435 .

[0063] At 420 , a selection of a portion of the content displayed on the outer ring is received.

[0064] According to an embodiment of the present invention, when the current Chinese Pinyin quick input mode is the final association mode, a selection of one of the one or more finals displayed on the outer ring that conform to the Pinyin spelling rules and can be combined with the initial consonant is received.

[0065] According to an embodiment of the present invention, when the current Chinese Pinyin quick input mode is the first stroke screening mode, a selection of one of the one or more first strokes of the candidate Chinese characters beginning with the initial consonant displayed on the outer ring is received.

[0066] At 425 , based on the selection of the portion of content, one or more candidate Chinese characters corresponding to the combination of the initial consonant selected in step 405 and the portion of content selected in step 420 are displayed in the candidate area.

[0067] According to an embodiment of the present invention, when the current Chinese Pinyin quick input mode is the vowel association mode, one or more candidate Chinese characters corresponding to the combination of the initial consonant selected in step 405 and the vowel selected in step 420 are displayed.

[0068] According to an embodiment of the present invention, when the current Chinese Pinyin quick input mode is the first stroke screening mode, one or more candidate Chinese characters corresponding to the combination of the initial consonant selected in step 405 and the first stroke selected in step 420 are displayed.

[0069] At 430, a selection of a candidate Chinese character from the one or more candidate Chinese characters is received.

[0070] At 435, the candidate Chinese characters selected in the candidate area are displayed in the input area.

[0071] Figure 5 1 shows a block diagram of a system 500 for Chinese input according to an embodiment of the present invention. The system 500 mainly includes a dual-ring keyboard display module 501, a candidate area display module 502, and an input area display module 503. It is fully understood by those skilled in the art that the system 500 can be integrated with an existing vehicle-mounted system in a vehicle or implemented as a separate system.

[0072] It is fully understood by those skilled in the art that the division of the above modules is only explained for the purpose of clarity. The functions of one or more of the above modules can be combined into a single module or split into more modules / submodules. Moreover, one or more of the above modules can be implemented by software, hardware or a combination thereof. In addition, the data flow between the modules can be implemented in a manner known in the art, which is not within the scope of the present invention.

[0073] According to one embodiment of the present invention, the dual-ring keyboard display module 501 can be configured to: display an inner ring, which displays one or more English characters arranged at a certain interval and one or more function options, and the one or more function options include a mode function option that can be selected to switch among multiple Chinese pinyin shortcut input modes; display an outer ring around the inner ring, and display content corresponding to the selected initial consonant on the outer ring based on the initial consonant selected through the inner ring and the current Chinese pinyin shortcut input mode to facilitate the selection of the desired Chinese characters.

[0074] According to one embodiment of the present invention, the candidate area display module 502 can be configured to: display a candidate area, which displays one or more candidate Chinese characters beginning with the initial consonant selected by the inner ring, or displays one or more candidate Chinese characters corresponding to a combination of the initial consonant selected by the inner ring and a portion of the content selected by the outer ring.

[0075] According to one embodiment of the present invention, the input area display module 503 can be configured to: display an input area that displays the initial consonants selected by the inner ring, or displays a combination of the initial consonants selected by the inner ring and the finals selected by the outer ring, or displays the candidate Chinese characters selected by the candidate area.

[0076] It can be seen that the present invention proposes a more effective input method to reduce user operations by improving the single-ring keyboard. The present invention presents two rings in the double-ring keyboard instead of the original single ring. Compared with the single ring of the single-ring keyboard, the inner ring of the double-ring keyboard of the present invention also adds a new function option, namely the "Quick Input Mode" button. Through this function option, you can switch between two input modes (stroke mode and pinyin mode). If the user selects the stroke mode, the outer ring will display the first stroke of one or more candidate Chinese characters starting with the selected initial consonant, and the user can select a specific first stroke from it, and the candidate area will display the candidate words containing only the first stroke. If the user selects the pinyin mode, the outer ring will display the candidate of one or more finals corresponding to the selected initial consonant, and the user can select a specific final from it, and the candidate area will display one or more candidate words corresponding to the combination of the initial consonant and the specific final. Thus, the outer ring can display useful information according to the input mode selected by the user, helping the user to improve input efficiency, or filter candidate words.
